Total Blood Loss (total + blood_loss)
Selected AbstractsThe effect of desmopressin on blood loss in patients with rheumatoid arthritis undergoing hip arthroplastyACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 7 2010K. A. LEINO Background: Blood loss is an important issue for patients with rheumatoid arthritis undergoing hip surgery. We hypothesised that intraoperative desmopressin treatment would result in a reduction in blood loss in rheumatoid patients undergoing total hip arthroplasty. Methods: Seventy-five patients scheduled for elective total hip arthroplasty were randomised to three groups to receive 0.4 ,g/kg desmopressin (D 0.4), 0.2 ,g/kg desmopressin (D 0.2) or placebo intraoperatively in a double-blind fashion. Blood transfusions were based on calculated safe allowable blood loss and haemoglobin measurements (trigger 90 g/l, 5.59 mmol/l). The primary endpoint was the total blood loss measured till the end of the fourth post-operative day. Secondary endpoints included red cell transfusion requirements and haemoglobin. Results: Total blood loss during the study period was not significantly different between the groups (D 0.4 1829 ± 1068; D 0.2 2240 ± 843 and placebo 2254 ± 1040 ml; P= 0.50). The total amount of red cell transfusions was fewer in group D 0.4 (3.6 ± 1.6 U) when compared with D 0.2 (4.4 ± 1.7 U; P=0.009) and placebo (4.5 ± 2.0 U; P= 0.011) groups. Haemoglobin concentration was lower in the placebo group in the first (5.42 ± 1.16 vs. 5.98 ± 0.47 mmol/l; P=0.033) and the second (6.28 ± 0.66 vs. 6.69 ± 0.47 mmol/l; P=0.033) post-operative mornings compared with group D 0.4. Conclusion: Despite a lack of difference in the primary outcome, total blood loss, intraoperative administration of 0.4 ,g/kg desmopressin resulted in fewer total red cell transfusion requirements in rheumatoid patients undergoing total hip arthroplasty when compared with 0.2 ,g/kg treatment and placebo. [source] Which may be effective to reduce blood loss after cardiac operations in cyanotic children: tranexamic acid, aprotinin or a combination?PEDIATRIC ANESTHESIA, Issue 1 2005FÜSUN S. BULUTCU MD Summary Background:, Children with cyanotic heart disease undergoing cardiac surgery in which cardiopulmonary bypass is used are at increased risk of postoperative bleeding. In this study, the authors investigated the possibility of reducing postoperative blood loss by using aprotinin and tranexamic acid alone or a combination of these two agents. Methods:, In a prospective, randomized, blind study, 100 children undergoing cardiac surgery were investigated. In group 1 (n = 25) patients acted as the control and did not receive either study drugs. In group 2 (n = 25) patients received aprotinin (30.000 KIU·kg,1 after induction of anesthesia, 30.000 KIU·kg,1 in the pump prime and 30.000 KIU·kg,1 after weaning from bypass). In group 3 (n = 25) patients received tranexamic acid (100 mg·kg,1 after induction of anesthesia, 100 mg·kg,1 in the pump prime and 100 mg·kg,1 after weaning from bypass). In group 4 (n = 25) patients received a combination of the two agents in the same manner. Total blood loss and transfusion requirements during the period from protamine administration until 24 h after admission to the intensive care unit were recorded. In addition, hemoglobin, platelet counts and coagulation studies were recorded. Results:, Postoperative blood loss was significantly higher in the control group (group 1) compared with children in other groups who were treated with aprotinin, tranexamic acid or a combination of the two agents (groups 2, 3 and 4) during the first 24 h after admission to cardiac intensive care unit (40 ± 18 ml·kg,1·24 h,1, aprotinin; 35 ± 16 ml·kg,1·24 h,1, tranexamic acid; 34 ± 19 ml·kg,1·24 h,1, combination; 35 ± 15 ml·kg,1·24 h,1). The total transfusion requirements were also significantly less in the all treatment groups. Time taken for sternal closure was longer in the control group (68 ± 11 min) compared with treatment groups 2, 3 and 4, respectively (40 ± 18, 42 ± 11, 42 ± 13 min, P < 0.05). The coagulation parameters were not found to be significantly different between the three groups. Conclusions:, Our results suggested that both agents were effective to reduce postoperative blood loss and transfusion requirements in patients with cyanotic congenital heart disease. However, the combination of aprotinin and tranexamic acid did not seem more effective than either of the two drugs alone.

[source] Application of cardiopulmonary bypass for resection of renal cell carcinoma and adrenocortical carcinoma extending into the right atriumINTERNATIONAL JOURNAL OF UROLOGY, Issue 3 2006TATSUMASA OCHI Aim:, The application of cardiopulmonary bypass to atrial involvement represents an important advance that has improved the safety and technical efficacy of a difficult surgical undertaking. Our experiences of the management of extended thrombi into the right atrium in patients with retroperitoneal malignancy using a cardiopulmonary bypass were discussed. Methods:, Data were reviewed for five patients (two men and three women; mean age, 60.4 years; range, 49,79 years) with retroperitoneal tumors displaying intracardiac tumor extension. Tumors originated in the right kidney in four patients, and in left adrenal gland in one patient. Cardiopulmonary bypass was used in all cases. Results:, Mean total blood loss was 6059 mL. Mean operative time was 14.7 h. No intra- or postoperative complications due to surgical technique were encountered, and no significant bleeding occurred during incision of the inferior vena cava or after removal of tumor thrombus. The follow-up period ranged from 3 to 20 months with a mean of 12.6 months. Of the five patients, three died of metastatic diseases, one died of liver dysfunction and one remains disease free as of 18 months postoperatively. Conclusions:, Our experience indicates that this procedure can be safely used for atrial involvement. Although superior long-term survival cannot be shown yet, favorable early results and a lack of perioperative complications were identified. [source] Phosphorylcholine-Coated Circuits Improve Preservation of Platelet Count and Reduce Expression of Proinflammatory Cytokines in CABG: A Prospective Randomized TrialJOURNAL OF CARDIAC SURGERY, Issue 4 2009Costas J. Schulze M.D. Phosphorylcholine (PC) is a new-generation coating material designed to ameliorate biocompatibility and thereby to reduce the detrimental interactions of CPB. We studied the effects of PC-coated perfusion circuits on platelet function and the humoral and cellular response to CPB. Methods: Thirty patients undergoing coronary artery bypass grafting were randomized to PC-coated (PC group, n = 15) and noncoated (control group, n = 15) circuit groups. Clinical data, total blood loss, and pre- and postoperative platelet counts were recorded and IL-6 and TNF-,, CD41a, CD42b, and CD62p were measured at induction of anesthesia, after the initiation of CPB and at termination of CPB. Results: There was a significantly improved preservation of platelet count following CPB in the PC group (p = 0.028), which was sustained over a period of 72 hours. The use of PC-coated circuits further resulted in a significant attenuation of TNF-, and IL-6 expression (p < 0.05 and p < 0.01); however, we were unable to detect any differences in clinical outcomes. Conclusions: Despite similar clinical outcome, the obvious reduction of cytokine expression and improved preservation of platelet count suggest superior biocompatibility of PC-coated circuits. [source] Ureteral catheter placement for prevention of ureteral injury during laparoscopic hysterectomyJOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 1 2008Yudai Tanaka Abstract Aim:, Ureteral injury is among the most devastating complications of gynecologic surgery. Estimated incidence of ureteral injury during laparoscopic hysterectomy is 2.6,35 times (0.2,6.0%) that in abdominal hysterectomy. We investigated preoperative ureteral catheter (UC) placement as a way to prevent ureteral injury in laparoscopic hysterectomy. Methods:, Clinical records of 94 women who underwent laparoscopic hysterectomy between February 2006 and January 2007 in Yazaki Hospital, Kanagawa, Japan, were reviewed retrospectively. Thirty-four patients between February and June 2006 underwent the surgery without ureteral catheterization and 60 patients between July 2006 and January 2007 underwent surgery with ureteral catheterization. Clinical outcomes were statistically compared between the two groups. Results:, The average time required for catheter insertion was 9.35 min. The ureter in which the catheter was placed was visualized clearly. In one patient, whose left ureter was deviated by a massive myoma, catheter insertion was not possible. No complications arose from catheter placement except for minor complaints including low back pain, urinary discomfort, and transient hamaturia. While one injury occurred in a patient without ureteral catheterization (1/34), no ureteral injury occurred in any patient with ureteral catheterization (0/60). Operative time, total blood loss, and hospital stay were not significantly different between the two groups. Conclusions:, UC placement is simple, helping to prevent ureteral injury during laparoscopic hysterectomy and enhancing safety of this procedure. [source] Oral misoprostol for the prevention of primary post-partum hemorrhage during third stage of laborJOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 6 2007Christopher A. Enakpene Abstract Aim:, To assess the effectiveness of oral misoprostol compared with methylergometrine in the prevention of primary post-partum hemorrhage during the third stage of labor. Methods:, This was a randomized controlled trial of 864 singleton low-risk pregnant women. The outcomes were total blood loss, duration of the third stage of labor and peripartal change in hematocrit. Comparisons were by the ,2 -test and Student t -test. Relative risks were calculated for side-effects profile. A P -value of less than 0.05 was statistically significant. Results:, The biodata of all the participants were similar. The mean blood loss for the misoprostol and methylergometrine groups was 191.6 ± 134.5 mL and 246.0 ± 175.5 mL, respectively (95% CI: ,79.3 to ,39.5 mL). The mean duration of the third stage of labor was 19.6 ± 2.4 min and 9.4 ± 3.3 min in the misoprostol and methylergometrine groups, respectively (95% CI: 9.82,10.58 min). More subjects had blood loss >500 mL, 42 (9.7%) versus 6 (1.4%), and peripartal hematocrit change greater than 10%, 38 (8.8%) versus 5 (1.2%), in the methylergometrine group than in the misoprostol group, respectively. Also, more subjects received additional oxytocic in the methylergometrine group, compared to the misoprostol group (80 [18.5%] versus 33 [7.6%] patients, respectively). Conclusions:, Orally administered misoprostol was more effective in reducing blood loss during the third stage of labor than intramuscular methylergometrine. However, there were more subjects in the misoprostol group in whom duration of the third stage of labor was greater than 15 min and who also had manual placental removal than in the methylergometrine group. [source] Increased blood loss in upright birthing positions originates from perineal damageBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 3 2007A De Jonge Objective, To assess whether the risk of severe blood loss is increased in semi-sitting and sitting position, and if so, to which extent blood loss from perineal damage is responsible for this finding. Design, Secondary analysis of data from a large trial. Setting, Primary care midwifery practices in the Netherlands. Population, About 1646 low-risk women who had a spontaneous vaginal delivery. Methods, Blood loss was measured using a weighing scale and measuring jug. Logistic regression analysis was used to examine the net effects of birthing position and perineal damage on blood loss greater than 500 ml. Main outcome measures, Mean total blood loss and incidence of blood loss greater than 500 ml and 1000 ml. Results, Mean total blood loss and the incidence of blood loss greater than 500 ml and 1000 ml were increased in semi-sitting and sitting position. In logistic regression analysis, the interaction between birthing position and perineal damage was almost significantly associated with an increased risk of blood loss greater than 500 ml. Semi-sitting and sitting position were only significant risk factors among women with perineal damage (OR 1.30, 95% CI 1.00,1.69 and OR 2.25, 95% CI 1.37,3.71, respectively). Among women with intact perineum, no association was found. Conclusions, Semi-sitting and sitting birthing positions only lead to increased blood loss among women with perineal damage. [source] Virtual reality simulation training can improve technical skills during laparoscopic salpingectomy for ectopic pregnancyBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 12 2006R Aggarwal Objectives, To assess the first commercially available virtual reality (VR) simulator to incorporate procedural modules for training of inexperienced gynaecological surgeons to perform laparoscopic salpingectomy for ectopic pregnancy. Design, Prospective cohort study. Setting, Departments of surgery and gynaecology in central London teaching hospitals. Sample, Thirty gynaecological surgeons were recruited to the study, and were divided into novice (<10 laparoscopic procedures), intermediate (20,50) and experienced (>100) groups. Methods, All subjects were orientated to the VR simulator with a basic skills task, followed by performing ten repetitions of the virtual ectopic pregnancy module, in a distributed manner. Main outcome measures, Operative performance was assessed by the time taken to perform surgery, blood loss and total instrument path length. Results, There were significant differences between the groups at the second repetition of the ectopic module for time taken (median 551.1 versus 401.2 versus 249.2 seconds, P= 0.001), total blood loss (median 304.2 versus 187.4 versus 123.3 ml, P= 0.031) and total instrument path length (median 17.8 versus 8.3 versus 6.8 m, P= 0.023). The learning curves of the experienced operators plateaued at the second session, although greater numbers of sessions were necessary for intermediate (seven) and novice (nine) surgeons to achieve similar levels of skill. Conclusions, Gynaecological surgeons with minimal laparoscopic experience can improve their skills during short-phase training on a VR procedural module. In contrast, experienced operators showed nonsignificant improvements. Thus, VR simulation may be useful for the early part of the learning curve for surgeons who wish to learn to perform laparoscopic salpingectomy for ectopic pregnancy. [source] |
