Selected AbstractsReduction of Early Postoperative Morbidity in Cardiac Surgery Patients Treated With Continuous Veno,Venous Hemofiltration During Cardiopulmonary BypassARTIFICIAL ORGANS, Issue 8 2009Remo Luciani Abstract Cardiac surgery with cardiopulmonary bypass is associated with a systemic inflammatory response syndrome. The major clinical features of this include a reduction of pulmonary compliance and increased extracellular fluids, with increased pulmonary shunt fraction similar to acute respiratory distress syndrome, thus resulting in prolonged mechanical ventilation time (VAM) and intensive care unit length of stay (ICU STAY). We evaluated the feasibility of an intraoperatory cardiopulmonary bypass (CPB) circuit connected with a monitor for continuous veno,venous hemofiltration (CVVH) to ameliorate pulmonary function after open heart surgery reducing VAM and ICU STAY. Forty patients undergoing elective coronary artery bypass grafting were randomized at the time of surgery into a control group (20 patients who received standard cardiopulmonary bypass) and a study group (20 patients who received CVVH during cardiopulmonary bypass). The analysis of postoperative variables showed a significative reduction of VAM in treated group (CVVH group mean 3.55 h ± 0.85, control group 5.8 h ± 0.94, P < 0.001) and ICU STAY (CVVH group mean 29.5 h ± 6.7, control group 40.5 h ± 6.67, P < 0.001). In our experience, the use of intraoperatory CVVH during cardiopulmonary bypass is associated with lower early postoperative morbidity. [source] Early predictability of the need for tracheotomy after admission to ICU: an observational studyACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 9 2010D. P. VEELO Background: The goal of this study was to explore the ability of professional judgment to predict the need for tracheotomy early among intensive care unit (ICU) patients. Methods: Prospective study using daily questionnaires among ICU physicians in a mixed medical,surgical ICU. The prediction of tracheotomy was by a visual analogue scale (VAS, from 1 to 10, with 1 representing ,absolutely no need for tracheotomy' and 10 representing ,pertinent need for tracheotomy') during ICU stay until tracheal extubation or tracheotomy. For the purpose of this study, a VAS score ,8 was considered a positive prediction for tracheotomy. Results: A total of 476 questionnaires were retrieved for 75 patients (6.4±5.2 questionnaires per patient), of which 11 patients finally proceeded with a tracheostomy. At first assessment (mean of 2.4±0.8 days after ICU admittance), ICU physicians predicted the need for tracheotomy 3.0 (2.0,6.0) higher VAS points for patients who were finally tracheotomized (P<0.01). Patients with a positive prediction had a 5.4 (1.2,24.1) higher chance of receiving tracheotomy (P=0.03). Considering the median VAS score over a maximum of 10 days before tracheotomy, ICU physicians scored tracheotomized patients significantly higher from day 8 onwards. When comparing ICU physicians, fellows and residents separately, only staff physicians scored a significant difference in the VAS score (P<0.05). Conclusion: ICU physicians are able to differentiate between patients in need for tracheotomy from those who do not, within 2 days from admittance. The closer the time to the actual intervention, the better the physicians are able to predict this decision. [source] Application of ECMO in Multitrauma Patients With ARDS as Rescue TherapyJOURNAL OF CARDIAC SURGERY, Issue 3 2007Navid Madershahian M.D. The final rescue therapy for patients with severe hypoxia refractory to conventional therapy modalities is the extracorporeal gas exchange. Methods: We report the management of three polytraumatized patients with life-threatening injuries, severe blunt thoracic trauma, and consecutive ARDS treating by extracorporeal membrane oxygenation (ECMO). Two patients suffered a car accident with severe lung contusion and parenychmal bleeding. Bronchial rupture and mediastinal emphysema was found in one of them. Another patient developed ARDS after attempted suicide with multiple fractures together with blunt abdominal and thoracic trauma. Results: All patients were placed on ECMO and could be rapidly stabilized. They were weaned from ECMO after a mean of 114 ± 27 hours of support without complications, respectively. Mean duration of ICU stay was 37 ± 23 days. Conclusions: Quick encouragement of ECMO for the temporary management of gas exchange may increase survival rates in trauma patients with ARDS. [source] Midterm Results of Off-Pump Coronary Artery Bypass Surgery in 136 Patients: An Angiographic Control StudyJOURNAL OF CARDIAC SURGERY, Issue 1 2006Hakki Kazaz M.D. This study summarizes the midterm results of 136 off-pump bypass surgery patients. Methods: Between January 2000 and March 2002, out of 178 surgical myocardial revascularizations, 136 (76.4%) were off-pump bypass surgery. Complete revascularization was done and especially arterial grafts were used. All patients were followed clinically and with treadmill test for 2 years. Average control angiography was performed at the end of 2-year follow-up. Results: Of all the patients, 56.7% were male and the mean age of the patients was 63.6 ± 7.4 years. A total of 481 anastomoses were performed,136 (28.27%) to the left anterior descending artery (LAD), 135 (28.07%) to the circumflex coronary artery (Cx) branches, 102 (21.20%) to the right coronary artery (RCA), 108 (22.46%) to the D,. The mean graft number was 3.46. We used 96.6% of patients' left internal mammarian artery (LITA), 29.2% radial artery (RA), 4.4% right internal thoracic artery (RITA), and 100% saphenous vein. There were ischemic changes within 12 patients. All ischemic changes came back to normal within 4 and 18 hours, postoperatively. Mean extubation time was 5.36 ± 2.23 hours, mean stay in intensive care unit was 17.53 ± 3.15 hours, mean hospital stay was 5.03 ± 1.29 days. The LITA patency was 99.25%, RA patency was 97.84%, RITA patency was 100%, and saphenous vein patency was 91.79% with control angiography. Conclusion: Off-pump coronary artery bypass graft (CABG) is efficient procedure with lower index of mortality, morbidity, ICU stay, hospital stay, good wound healing, early socialization, and results in lower costs. [source] Prethymectomy plasmapheresis in myasthenia gravisJOURNAL OF CLINICAL APHERESIS, Issue 4 2005Jiann-Horng Yeh Abstract Plasma exchange before thymectomy may decrease the time on mechanical ventilation (MV) and shorten the stay in the intensive care unit (ICU) for patients with myasthenia gravis (MG). This study evaluated the effects of prethymectomy plasmapheresis. A total of 29 myasthenic patients, 18 women and 11 men aged 20,73 years, were treated with double filtration plasmapheresis (DFP) for two to five consecutive sessions over a period between 2 and 21 days (mean 8.1 days) before transsternal thymectomy. Acetylcholine receptor antibody (AchRAb) titers, vital capacity (VC), maximal inspiratory pressure (Pimax), and MG score were measured before and after the course of DFP. Three outcome measures including duration of postoperative hospital stay, duration of ICU stay, and duration of MV were analyzed for correlation with clinical variables. The duration of MV ranged from 6 to 93 h, with a median of 21 h. The median ICU stay was one day and the median postoperative hospital stay was 10 days. A higher removal rate of AchRAb was associated with a shorter duration of ICU and postoperative hospital stay (P = 0.001 and 0.019, respectively). Postoperative hospital stay was strongly correlated with post-DFP Pimax (P = 0.010), and marginally correlated with pre-DFP VC (P = 0.047) and to a lesser extent with pre-DFP Pimax (P = 0.063). Univariate analysis using the log rank test revealed that removal rate of AchRAb <30% (P = 0.043) and pre-DFP Pimax <,60 cmH2O (P = 0.024) were significantly associated with prolonged ICU stay. Risk factors for prolonged postoperative stay included post-DFP Pimax <,60 cmH2O (P = 0.017), pre-DFP Pimax <,60 cmH2O (P = 0.031), and post-DFP VC < 1.0 L (P = 0.046). Our results confirmed the efficacy and safety of DFP in prethymectomy preparation for myasthenic patients. J. Clin. Apheresis, 2005 © 2005 Wiley-Liss, Inc. [source] Factual memories of ICU: recall at two years post-discharge and comparison with delirium status during ICU admission , a multicentre cohort studyJOURNAL OF CLINICAL NURSING, Issue 9 2007Brigit L Roberts RN, IC Cert Aims and objective., To examine the relationship between observed delirium in ICU and patients' recall of factual events up to two years after discharge. Background., People, the environment, and procedures are frequently cited memories of actual events encountered in ICU. These are often perceived as stressors to the patients and the presence of several such stressors has been associated with the development of reduced health-related quality of life or post-traumatic stress syndrome. Design., Prospective cohort study using interview technique. Method., The cohort was assembled from 152 patients who participated in a previously conducted multi-centre study of delirium incidence in Australian ICUs. The interviews involved a mixture of closed- and open-ended questions. Qualitative responses regarding factual memories were analysed using thematic analysis. A five-point Likert scale with answers from ,always' to ,never' was used to ask about current experiences of dream, anxiety, sleep problems, fears, irritability and/or mood swings. Scoring ranged from 6 to 30 with a mid-point value of 18 indicating a threshold value for the diagnosis of post-traumatic stress syndrome. A P -value of <0·05 was considered significant for all analyses. Results., Forty-one (40%) out of 103 potential participants consented to take part in the follow-up interview; 18 patients (44%) had been delirious and 23 patients (56%) non-delirious during the ICU admission. The non-participants (n = 62) formed a control group to ensure a representative sample; 83% (n = 34) reported factual memories either with or without recall of dreaming. Factual memories were significantly less common (66% cf. 96%) in delirious patients (OR 0·09, 95%CI 0·01,0·85, p = 0·035). Five topics emerged from the thematic analysis: ,procedures', ,staff', ,comfort', ,visitors', and ,events'. Based on the current experiences, five patients (12%, four non-delirious and one delirious) scored ,18 indicative of symptoms of post-traumatic stress syndrome; this did not reach statistical significance. Memory of transfer out of ICU was less frequent among the delirious patients (56%, n = 10) than among the non-delirious patients (87%, n = 20) (p = 0·036). Conclusion., Most patients have factual memories of their ICU stay. However, delirious patients had significantly less factual recall than non-delirious patients. Adverse psychological sequelae expressed as post-traumatic stress syndrome was uncommon in our study. Every attempt must be made to ensure that the ICU environment is as hospitable as possible to decrease the stress of critical illness. Post-ICU follow-up should include filling in the ,missing gaps', particularly for delirious patients. Ongoing explanations and a caring environment may assist the patient in making a complete recovery both physically and mentally. Relevance to clinical practice., This study highlights the need for continued patient information, re-assurance and optimized comfort. While health care professionals cannot remove the stressors of the ICU treatments, we must minimize the impact of the stay. It must be remembered that most patients are aware of their surroundings while they are in the ICU and it should, therefore, be part of ICU education to include issues regarding all aspects of patient care in this particularly vulnerable subset of patients to optimize their feelings of security, comfort and self-respect. [source] RIFLE classification as predictive factor of mortality in patients with cirrhosis admitted to intensive care unitJOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 10 2009Evangelos Cholongitas Abstract Background and Aim:, To evaluate the association of the Risk, Injury, Failure, Loss and End-stage renal failure (RIFLE) score on mortality in patients with decompensated cirrhosis admitted to intensive care unit (ICU). Methods:, A cohort of 412 patients with cirrhosis consecutively admitted to ICU was classified according to the RIFLE score. Multivariable logistic regression analysis was used to evaluate the factors associated with mortality. Liver-specific, Acute Physiology and Chronic Health Evaluation (APACHE) II, Sequential Organ Failure Assessment (SOFA) and RIFLE scores on admission, were compared by receiver,operator characteristic curves. Results:, The overall mortality during ICU stay or within 6 weeks after discharge from ICU was 61.2%, but decreased over time (76% during first interval, 1989,1992 vs 50% during the last, 2005,2006, P < 0.001). Multivariate analysis showed that RIFLE score (odds ratio: 2.1, P < 0.001) was an independent factor significantly associated with mortality. Although SOFA had the best discrimination (area under receiver,operator characteristic curve = 0.84), and the APACHE II had the best calibration, the RIFLE score had the best sensitivity (90%) to predict death in patients during follow up. Conclusions:, RIFLE score was significantly associated with mortality, confirming the importance of renal failure in this large cohort of patients with cirrhosis admitted to ICU, but it is less useful than other scores. [source] Gastrointestinal symptoms in intensive care patientsACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 3 2009A. REINTAM Background: Gastrointestinal (GI) problems are not uniformly assessed in intensive care unit (ICU) patients and respective data in available literature are insufficient. We aimed to describe the prevalence, risk factors and importance of different GI symptoms. Methods: We prospectively studied all patients hospitalized to the General ICU of Tartu University Hospital in 2004,2007. Results: Of 1374 patients, 62 were excluded due to missing data. Seven hundred and seventy-five (59.1%) patients had at least one GI symptom at least during 1 day of their stay, while 475 (36.2%) suffered from more than one symptom. Absent or abnormal bowel sounds were documented in 542 patients (41.3%), vomiting/regurgitation in 501 (38.2%), high gastric aspirate volume in 298 (22.7%), diarrhoea in 184 (14.0%), bowel distension in 139 (10.6%) and GI bleeding in 97 (7.4%) patients during their ICU stay. Absent or abnormal bowel sounds and GI bleeding were associated with significantly higher mortality. The number of simultaneous GI symptoms was an independent risk factor for ICU mortality. The ICU length of stay and mortality of patients who had two or more GI symptoms simultaneously were significantly higher than in patients with a maximum of one GI symptom. Conclusion:, GI symptoms occur frequently in ICU patients. Absence of bowel sounds and GI bleeding are associated with impaired outcome. Prevalence of GI symptoms at the first day in ICU predicts the mortality of the patients. [source] Lactobacillus plantarum 299v reduces colonisation of Clostridium difficile in critically ill patients treated with antibioticsACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 8 2008B. KLARIN Background: The incidence of Clostridium difficile -associated disease (CDAD) in hospitalised patients is increasing. Critically ill patients are often treated with antibiotics and are at a high risk of developing CDAD. Lactobacillus plantarum 299v (Lp299v) has been found to reduce recurrence of CDAD. We investigated intensive care unit (ICU) patients with respect to the impact of Lp299v on C. difficile colonisation and on gut permeability and parameters of inflammation and infection in that context. Methods: Twenty-two ICU patients were given a fermented oatmeal gruel containing Lp299v, and 22 received an equivalent product without the bacteria. Faecal samples for analyses of C. difficile and Lp299v were taken at inclusion and then twice a week during the ICU stay. Other cultures were performed on clinical indication. Infection and inflammation parameters were analysed daily. Gut permeability was assessed using a sugar probe technique. Results: Colonisation with C. difficile was detected in 19% (4/21) of controls but in none of the Lp299v-treated patients (P<0.05). Conclusions: Enteral administration of the probiotic bacterium Lp299v to critically ill patients treated with antibiotics reduced colonisation with C. difficile. [source] Serum osmolality and outcome in intensive care unit patientsACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 8 2006B. Holtfreter Background:, The aim of the present study was to compare 16 routine clinical and laboratory parameters, acute physiologic and chronic health evaluation (APACHE) and sequential organ failure assessment (SOFA) score for their value in predicting mortality during hospital stay in patients admitted to a general intensive care unit (ICU). Methods:, A retrospective observational clinical study was carried out in a 15-bed ICU in a university hospital. Nine hundred and thirty-three consecutive patients with ICU stay > 24 h (36.2% surgical, 29.1% medical and 34.7% trauma) were observed. Blood sampling, patient surveillance and data collection were performed. The primary outcome was mortality in the hospital. We used receiver operating characteristic (ROC) analyses and logistic regression to compare the 16 relevant parameters, APACHE II and SOFA scores. Results:, Two hundred and thirty-three out of the 933 patients died (mortality 25.0%). One laboratory parameter, serum osmolality [area under the curve (AUC) 0.732] had a predictive value for mortality which lay between that of APACHE II (AUC 0.784) and SOFA (AUC 0.720) scores. When outcome prediction was restricted to long-term patients (ICU stay > 5 days), serum osmolality (AUC 0.711) performed better than either of the standard scores (APACHE AUC 0.655, SOFA AUC 0.636). Using logistic regression analysis, the association of clinical parameters, age and diagnosis group with mortality was determined. Conclusion:, Elevated serum osmolality at ICU admission is associated with an increased mortality risk in critically ill patients. Serum osmolality is cheaper and more rapid to determine than the scoring systems. However, further studies are needed to evaluate the predictive value of serum osmolality in different patient populations. [source] Development of renal failure during the initial 24 h of intensive care unit stay correlates with hospital mortality in trauma patientsACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 7 2006T. Ala-Kokko Background:, Although multiple organ failure is the leading late cause of death, there is controversy about the impact of acute organ dysfunction and failure on trauma survival. Methods:, Consecutive adult trauma admissions between January 2000 and June 2003, excluding isolated head traumas and burns, were analysed for parameters of organ function during the first 24 h following intensive care unit (ICU) admission using the Sequential Organ Failure Assessment (SOFA) scoring system. A national prospectively collected ICU data registry was used for analysis, including data from 22 ICUs in university and central hospitals in Finland. Results:, The study population consisted of 1044 eligible trauma admissions; 32% of the cases were treated at university hospital level, the rest being secondary referral central hospital admissions. The mean Acute Physiology and Chronic Health Evaluation (APACHE) II score was 15 (SD8), ICU mortality was 5.6% and a further 1.6% of patients died during their post-ICU hospital stay. Forty-five per cent of the patients were categorized as having multiple traumas. In univariate analysis, APACHE II , 25 [odds ratio (OR), 35; 95% confidence interval (CI), 18,66] and renal failure (OR, 29.5; 95% CI, 14,63) produced the highest ORs for ICU mortality. In the APACHE II-, sex- and age-adjusted logistic regression model, renal failure was a significant risk factor for both ICU and hospital mortality (OR, 11.8; 95% CI, 3.9,35.4; OR, 8.2; 95% CI, 2.9,23.2, respectively). Conclusion:, The development of renal failure during the initial 24 h of ICU stay remained an independent risk factor for mortality in trauma patients requiring intensive care treatment even after adjusting for the APACHE II score, age and sex. [source] Identification and characterization of errors and incidents in a medical intensive care unitACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 7 2005J. Graf Background:, To assess the frequency, type, consequences, and associations of errors and incidents in a medical intensive care unit (ICU). Methods:, Two-hundred and sixteen consecutive patients with predominantly cardiovascular and pulmonary disorders admitted between December 2002 and February 2003 were enrolled. Demographic data, SAPS II, and TISS-28 were obtained for all patients. Prior to patient enrolment all staff members (physicians, nurses, physiotherapists) were repeatedly encouraged to make use of the Incident Report Form (IRF) and detailed descriptions on how, why and when to use the IRF were provided. Results:, During the observation period of 64 days, 50 errors involving 32 patients (15%) were reported. Patients subjected to errors were more severely ill (SAPS II 42 ± 25 vs. 32 ± 18, P < 0.05), had a higher hospital mortality (38% vs. 9%), and a longer ICU stay (11 ± 18 vs. 3 ± 5 days, P < 0.05). Gender, age and TISS-28 were equally distributed. Each day of ICU stay increased the risk by 8% (odds ratio 1.078, 95% confidence interval 1.034,1.125, P < 0.001), and by 2.3% per SAPS II point (odds ratio 1.023, 95% confidence interval 1.006,1.040, P < 0.001). The majority of errors and incidents were judged as ,human failures' (73%), and 46 errors and incidents (92%) as ,avoidable'. Conclusions:, The identification and characterization of errors and incidents combined with contextual information is feasible and may provide sufficient background information for areas of quality improvement. Areas with a high frequency of errors and incidents need to undergo process evaluation to avoid future occurrence. [source] Use and practice of patient diaries in Swedish intensive care units: a national surveyNURSING IN CRITICAL CARE, Issue 1 2010Eva Åkerman Aims and objectives: To describe and compare the extent and application of patients' diaries in Sweden. Background: Since 1991, patient diaries have been used in intensive care unit (ICU) follow-up in Sweden. There is paucity of relevant data evaluating the effect of this tool and also on what premises patients are enrolled. Likewise, data are sparse on the diaries' design, content structure and the use of photographs. Design: Descriptive explorative design by a semi-structured telephone interview. Methods: The interview results were analysed with descriptive statistics and differences between the ICU levels were explored by ,2 analysis. Qualitative manifest content analysis was performed to explore the purpose of diary writing. Results: Of all ICUs (n = 85), 99% responded and 75% used diaries. The source of inspiration was collegial rather than from scientific data. The main reason for keeping a diary was to help the patient to recapitulate the ICU stay. Discrepancies between the different levels of ICUs were detected in patient selection, dedicated staff for follow-up and the use of photographs. Comparison between the ,2 analysis and the content analysis outcome displayed incongruence between the set unit-goals and the activities for achievement but did not explain the procedural differences detected. Conclusion: The uses of diaries in post ICU follow up were found to be common in Sweden. A majority used defined goals and content structure. However, there were differences in practice and patient recruitment among the levels of ICUs. These discrepancies seemed not to be based on evidence-based data nor on ongoing research or evaluation but merely on professional judgement. As ICU follow-up is resource intense and time consuming, it is paramount that solid criteria for patient selection and guidelines for the structure and use of diaries in post-ICU follow-up are defined. [source] Home care for chronic respiratory failure in children: 15 years experiencePEDIATRIC ANESTHESIA, Issue 4 2002L. APPIERTO MD Background:,Advances in paediatric intensive care have reduced mortality but, unfortunately, one of the consequences is an increase in the number of patients with chronic diseases. It is generally agreed that home care of children requiring ventilatory support improves their outcomes and results in cost saving for the National Health Service. Methods:,Since 1985, the Children's Hospital Bambino Gesù of Rome has developed a program of paediatric home care. The program is performed by a committed Home Health Care Team (HHCT) which selects the eligible patients for home care and trains the families to treat their child. During the period January 1985 to January 2001, 53 children with chronic respiratory failure were included in the home care program. Of these, seven patients were successively excluded and six died in our intensive care unit (ICU), while one still lives in our ICU since 1997. The results obtained in the remaining 46 children are reported. Results:,The pathologies consisted of disorders of respiratory control related to brain damage (26%), upper airways obstructive disease (26%), spinal muscular atrophy (22%), myopathies and muscular dystrophies (6.5%), bronchopulmonary dysplasia (6.5%), tracheomalacia (6.5%), central hypoventilation syndrome (4.3%) and progressive congenital scoliosis (2.2%). Of these 46 patients, 34 children are mechanically ventilated and the median of their ICU stay was 109.5 days (range 54,214 days), while the remaining 12 children were breathing spontaneously and the median of their ICU stay was 90.5 days (range 61,134 days). We temporarily readmitted six patients to our ICU to perform scheduled otolaryngological surgery, eight patients for acute respiratory infections and two patients for deterioration of their neurological status due to high pressure hydrocephalus for placement of a ventriculoperitoneal shunt; these 16 patients were discharged back home again. Two other patients were readmitted for deterioration of their chronic disease and died in our ICU, while seven patients died at home. Conclusions:,Thirty-seven children are still alive at home and four of them improved their respiratory condition so that it was possible to remove the tracheostomy tube. Our oldest patient has now achieved 15 years of mechanical ventilation at home. [source] Progression of Organ Failure in Patients Approaching Brain Stem DeathAMERICAN JOURNAL OF TRANSPLANTATION, Issue 6 2009F. T. Lytle We performed a retrospective cohort study to document the progression of organ dysfunction in 182 critically ill adult patients who subsequently met criteria for brain stem death (BSD). Patients were admitted to intensive care units (ICUs) of Mayo Medical Center, Rochester, MN, between January 1996 and December 2006. Daily sequential organ failure assessment (SOFA) scores were used to assess the degree of organ dysfunction. Serial SOFA scores were analyzed using analysis of variance (ANOVA). Mean (standard deviation, SD) SOFA score on the first ICU day was 8.9 (3.2). SOFA scores did not significantly change over the course of ICU stay. 67.6% of patients donated one or more organs after BSD was declared. The median time from ICU admission to declaration of BSD was 18.8 h (interquartile range 10.3,45.0), and in those who donated organs, the time from declaration of BSD to organ retrieval was 11.8 h (9.5,17.6). The fact that mean SOFA scores did not change significantly over time, even after BSD occurred, has implications for the timing of retrieval of organs for transplantation. [source] Survival and length of stay following blood transfusion in octogenarians following cardiac surgeryANAESTHESIA, Issue 4 2010T. Veenith Summary Our aim was to assess if peri-operative blood transfusion is an independent risk factor for mortality and morbidity in the elderly. We report the results of a cohort study of all patients aged 80 or more on the day of their emergency or elective cardiac surgery (n = 874), using routinely collected data from January 2003 to November 2007. The primary outcome was all-cause mortality in hospital. The secondary outcomes were duration of stay in the intensive care unit (ICU) and overall hospital stay. Confounding variables were used to build up a risk model using a multivariable logistic regression analysis, and blood transfusion was added to assess whether it had additional predictive value for hospital mortality. Patients were divided into three groups: (i) transfusion of 0,2 units of red blood cells; (ii) transfusion of > 2 units of red blood cells and (iii) transfusion of red blood cells plus other clotting products. The strongest independent predictors of hospital death were logistic EuroSCORE and body mass index. After inclusion of these two variables, the odds ratio for transfusion remained significant. Relative to 0,2 units, the odds ratio for > 2 units was 6.80 (95% CI 2.46,18.8), and for other additional blood products was 14.4 (95% CI 5.34,37.3), with a p value of < 0.001. Duration of stay in the ICU was significantly associated with the amount of blood products administered (median (IQR [range]) ICU stay 1 (1-2 [0-15]) day if transfused 0,2 units of red blood cells, 2 (1-6 [0-128]) days if transfused > 2 units of red blood cells and 3 (1-76 [0-114]) days if other clotting products were used; p value < 0.001). Hospital stay was also associated with the amount of red cells used (p < 0.001). [source] Impact of introducing a sedation management guideline in intensive careANAESTHESIA, Issue 3 2006C. Adam Summary To ensure that sedative agents in the intensive care unit are used for maximum benefit, a guideline that promotes the accurate and continuous assessment of patients' needs is indicated. This observational 24-month prospective study investigated the effect of introducing a sedation management guideline into a 10-bedded multidisciplinary intensive care unit on length of stay, severity of illness, mortality and the number of bed days provided. Costs for all sedative drugs were calculated as cost per bed day. Intensive care unit mortality remained constant before and after guideline introduction. The length of stay of non-cardiac surgery patients was mean (SD) 4.6 (4.4) and 5.1 (4.3) days, respectively (p = 0.2). Monthly sedative cost before guideline introduction was £6285 compared to £3629 afterwards (p,0.0001), representing a real saving of £63 759 in sedative costs over the 2 years following introduction of the guideline. Guideline-directed management for sedation significantly reduces the cost of sedative drugs per bed day without any negative effect on length of ICU stay and outcome. [source] Epidemiology of post-injury multiple organ failure in an Australian trauma systemANZ JOURNAL OF SURGERY, Issue 6 2009David C. Dewar Abstract Background:, The epidemiology of post-injury multiple organ failure (MOF) is reported internationally to have gone through changes over the last 15 years. The purpose of this study is to describe the epidemiology of post-injury MOF in Australia. Methods:, A 12-month prospective epidemiological study was performed at the John Hunter Hospital (Level-1 Trauma Centre). Demographics, injury severity (ISS), physiological parameters, MOF status and outcome data were prospectively collected on all trauma patients who met inclusion criteria (ICU admission; ISS > 15; age > 18, head Abbreviated Injury Scale (AIS) <3 and survival >48 h). MOF was prospectively defined by the Denver MOF score greater than 3 points. Data are presented as % or Mean+/,SEM. Univariate statistical comparison was performed (Student t -test, X2 test), P < 0.05 was considered significant. Results:, Twenty-nine patients met inclusion criteria (Age 40+/,4, ISS 29+/,3, Male 62%), five patients developed MOF. The incidence of MOF among trauma patients admitted to ICU was 2% (5/204) and 17% (5/29) in the high-risk cohort. The maximum average MOF score was 6.3 +/,1, with the average duration of MOF 5+/,2 days. Two patients had respiratory and cardiac failure, two patients had failure of respiratory, cardiac and hepatic systems, while one patient had failure of respiratory, hepatic and renal systems. One MOF patient died, all non MOF patients survived. MOF patients had longer ICU stays (20+/,4 versus 7+/,0.8 P= 0.01), tended to be older (60+/,11 versus 35+/,4 p=0.07). None of the previously described independent predictors (ISS, base deficit, lactate, transfusions) were different when the MOF patients were compared with the non-MOF patients. Conclusion:, The incidence of MOF in Australia is consistent with the international data. In Australia MOF continues to cause significant late mortality and morbidity in trauma patients. MOF patients have longer ICU stay than high-risk non MOF patients, and use significant resources. Our preliminary data challenges the timeliness of the 10-year-old independent predictors of post-injury MOF. The epidemiology, the clinical presentation and the independent predictors of post-injury MOF require larger scale reassessment for the Australian context. [source] CT02 A STUDY TO EVALUATE VARIOUS TECHNIQUES OF CORONARY ARTERY BYPASS GRAFTINGANZ JOURNAL OF SURGERY, Issue 2007P. Singhal Introduction In Wellington Hospital, CABG is being performed by various techniques like OPCAB, On-pump cardioplegic arrest, fibrillatory arrest and On-pump beating heart. Aim This study was undertaken to compare morbidity and mortality between On- pump CABG and OPCAB on basis of Euroscore. Material and Method From January 2003 till December 2004, data were collected according to Australasian society of Cardiothoracic surgery data set. Euroscores were calculated and patients were divided into 3 groups. Results of OPCAB and On-pump CABG were compared on basis of Euroscore group. In this period we performed 350 On-pump CABG and 254 OPCAB. Results OPCAB group had less number of grafts per patients. Even for triple vessel disease numbers of grafts were lower in OPCAB group. OPCAB group had more patients with total arterial revascularization. There were 10 deaths in On-pump group and 1 in OPCAB group. In the low and moderate risk group there was no significant difference in hospital stay, ventilation hours and ICU stay. However inotropic requirement and requirements of blood products were less in OPCAB group. There was no statistically significant difference between Incidence of new renal failure or arrhythmia in two groups. 2 patients in each group had blocked graft in immediate postop period and required revascularization. There were only 5 patients in the high-risk group in OPCAB making intergroup comparisons difficult. Conclusion OPCAB does not offer any significant advantage in terms of mortality and morbidity over On-pump CABG. To evaluate the effects of number of grafts and total arterial revascularization, it needs a long-term follow-up. [source] Relationship between elevated preoperative troponin T and adverse outcomes following cardiac surgeryANZ JOURNAL OF SURGERY, Issue 1-2 2003William J. Lyon Background: The prognostic value of troponin T (TnT) has been demonstrated in patients following a myocardial infarction. There are limited data regarding the prognostic utility of preoperative TnT in patients undergoing cardiac surgery. The aim of the present study was to determine if elevated preoperative TnT is a predictor of more complex recovery outcomes in the cardiac surgical setting. Methods: A single preoperative TnT measurement was assessed in 696 patients undergoing isolated coronary artery bypass graft surgery. Elevated preoperative TnT levels were classified as ,0.2 ng/mL. Preoperative, intraoperative, intensive care and postoperative events were prospectively recorded for all patients, and retrospectively reviewed for the present study. Results: Elevated preoperative TnT levels were detected in 10% (71/696) of patients. Compared to patients with normal TnT levels, elevated preoperative TnT increased the risk of mortality at 30 days (7%vs 1%, P = 0.004, odds ratio (OR) = 6.7) and 2 years (14%vs 3%, P < 0.001, OR = 5.0), and resulted in prolonged intensive care unit (ICU) stays (P < 0.001) and longer postoperative hospitalization (P < 0.001). Elevated preoperative TnT was also associated with an increased need for perioperative and postoperative cardiovascular support, early ischaemic change and postoperative congestive cardiac failure. In multivariate analyses preoperative TnT was a significant independent predictor of 30-day and 2-year mortality, and duration of ICU stay. Conclusions: Elevated preoperative TnT highlights a subgroup of cardiac surgical patients who are more likely to have a postoperative course with increased morbidity and mortality. [source] Comparison of Sustained Hemodiafiltration With Continuous Venovenous Hemodiafiltration for the Treatment of Critically Ill Patients With Acute Kidney InjuryARTIFICIAL ORGANS, Issue 4 2010Masanori Abe Abstract Despite improvements in medical care, the mortality of critically ill patients with acute kidney injury (AKI) who require renal replacement therapy (RRT) remains high. We describe a new approach, sustained hemodiafiltration, to treat patients who suffered from acute kidney injury and were admitted to intensive care units (ICUs). In our study, 60 critically ill patients with AKI who required RRT were treated with either continuous venovenous hemodiafiltration (CVVHDF) or sustained hemodiafiltration (S-HDF). The former was performed by administering a postfilter replacement fluid at an effluent rate of 35 mL/kg/h, and the latter was performed by administering a postfilter replacement fluid at a dialysate-flow rate of 300,500 mL/min. The S-HDF was delivered on a daily basis. The baseline characteristics of the patients in the two treatment groups were similar. The primary study outcome,survival until discharge from the ICU or survival for 30 days, whichever was earlier,did not significantly differ between the two groups: 70% after CVVHDF and 87% after S-HDF. The hospital-survival rate after CVVHDF was 63% and that after S-HDF was 83% (P < 0.05). The number of patients who showed renal recovery at the time of discharge from the ICU and the hospital and the duration of the ICU stay significantly differed between the two treatments (P < 0.05). Although there was no significant difference between the mean number of treatments performed per patient, the mean duration of daily treatment in the S-HDF group was 6.5 ± 1.0 h, which was significantly shorter. Although the total convective volumes,the sum of the replacement-fluid and fluid-removal volumes,did not differ significantly, the dialysate-flow rate was higher in the S-HDF group. Our results suggest that in comparison with conventional continuous RRT, including high-dose CVVHDF, more intensive renal support in the form of postdilution S-HDF will decrease the mortality and accelerate renal recovery in critically ill patients with AKI. [source] Coronary Artery Bypass Grafting for Hemodialysis- Dependent PatientsARTIFICIAL ORGANS, Issue 4 2001Hitoshi Hirose Abstract: Patients with end-stage renal disease carry a risk of coronary atherosclerosis. This study was performed to evaluate the perioperative and remote data of coronary artery bypass grafting (CABG) in hemodialysis dependent patients. We retrospectively analyzed the results of isolated CABG performed at Shin-Tokyo Hospital between June 1, 1993 and May 31, 2000. Preoperative, perioperative, and follow-up data of the patients on hemodialysis (Group HD, n = 37) were collected and compared with those of control patients (Group C, n = 1,639). Group HD consisted of 26 males and 11 females with a mean age of 59.9 ± 8.1 years, and the mean number of bypasses was 2.5 ± 1.1. Group HD had a longer postoperative intubation time, ICU stay, and hospital stay than Group C. The postoperative major complication rate in Group HD (18.9%) was not significantly different from that in Group C (11.3%). However, the inhospital mortality rate in Group HD (5.4%) was higher than Group C (0.6%). At the mean follow-up of 2.4 years, the actuarial 3-year survival of Groups HD and C were 90.6% and 97.6%, respectively (p < 0.001), excluding hospital mortality. The actuarial 3-year cardiac event-free rates were 84.3% in Group HD and 88.8% in Group C, showing no difference. Patients on chronic hemodialysis carry a significant risk of prolonged inhospital care and hospital death. Once successful surgical revascularization was completed, their long-term cardiac events could be controlled as effectively. The increased distant death rates was probably associated with the nature of renal disease. [source] Tongue weakness is associated with respiratory failure in patients with severe Guillain-Barré syndromeACTA NEUROLOGICA SCANDINAVICA, Issue 6 2009D. Orlikowski Objective,,, Swallowing impairment may worsen respiratory weakness and conduct to respiratory complications such as aspiration pneumonia in Guillain-Barré syndrome (GBS). We prospectively evaluate how tongue weakness could be associated to bulbar dysfunction and respiratory weakness in severe GBS patients. Measurements and main results,,, Tongue strength, dysphagia and respiratory parameters were measured in 16 GBS patients at intensive care unit (ICU) admission and discharge and in seven controls. Tongue strength was decreased in the GBS patients compared with the controls. At admission, patients with dysphagia and those requiring mechanical ventilation (MV) had greater tongue weakness. All the patients with initial tongue strength <150 g required MV during ICU stay. Tongue strength correlated significantly with respiratory parameters. Conclusion,,, This study confirms the strong association between bulbar and respiratory dysfunction in GBS admitted to ICU. Tongue weakness may be present in GBS, especially during the phase of increasing paralysis, and resolves during the recovery phase. Tongue strength and indices of global and respiratory strength vary in parallel throughout the course of GBS. Further studies are needed to assess if, when used in combination with other respiratory tests, tongue strength measurement could contribute to identify patients at high risk for respiratory complications. [source] Epidemiology of post-injury multiple organ failure in an Australian trauma systemANZ JOURNAL OF SURGERY, Issue 6 2009David C. Dewar Abstract Background:, The epidemiology of post-injury multiple organ failure (MOF) is reported internationally to have gone through changes over the last 15 years. The purpose of this study is to describe the epidemiology of post-injury MOF in Australia. Methods:, A 12-month prospective epidemiological study was performed at the John Hunter Hospital (Level-1 Trauma Centre). Demographics, injury severity (ISS), physiological parameters, MOF status and outcome data were prospectively collected on all trauma patients who met inclusion criteria (ICU admission; ISS > 15; age > 18, head Abbreviated Injury Scale (AIS) <3 and survival >48 h). MOF was prospectively defined by the Denver MOF score greater than 3 points. Data are presented as % or Mean+/,SEM. Univariate statistical comparison was performed (Student t -test, X2 test), P < 0.05 was considered significant. Results:, Twenty-nine patients met inclusion criteria (Age 40+/,4, ISS 29+/,3, Male 62%), five patients developed MOF. The incidence of MOF among trauma patients admitted to ICU was 2% (5/204) and 17% (5/29) in the high-risk cohort. The maximum average MOF score was 6.3 +/,1, with the average duration of MOF 5+/,2 days. Two patients had respiratory and cardiac failure, two patients had failure of respiratory, cardiac and hepatic systems, while one patient had failure of respiratory, hepatic and renal systems. One MOF patient died, all non MOF patients survived. MOF patients had longer ICU stays (20+/,4 versus 7+/,0.8 P= 0.01), tended to be older (60+/,11 versus 35+/,4 p=0.07). None of the previously described independent predictors (ISS, base deficit, lactate, transfusions) were different when the MOF patients were compared with the non-MOF patients. Conclusion:, The incidence of MOF in Australia is consistent with the international data. In Australia MOF continues to cause significant late mortality and morbidity in trauma patients. MOF patients have longer ICU stay than high-risk non MOF patients, and use significant resources. Our preliminary data challenges the timeliness of the 10-year-old independent predictors of post-injury MOF. The epidemiology, the clinical presentation and the independent predictors of post-injury MOF require larger scale reassessment for the Australian context. [source] |
