Glasgow Coma Scale Score (glasgow + coma_scale_score)
Selected AbstractsChildhood encephalopathy: viruses, immune response, and outcomeDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 4 2006Michael Clarke BSc MB ChB FRCPCH This study examined children with an acute encephalopathy illness for evidence of viral infection, disordered blood-brain barrier function, intrathecal immunoglobulin synthesis, and interferon (IFN) production, and related their temporal occurrence to outcome. A prospective study of 22 children (13 males, 9 females; age range 1mo to 13y, median 2y 4mo), recorded clinical details, with serum and cerebrospinal fluid (CSF) analysis near presentation and then on convalescent specimens taken up to day 39 of the neurological illness. Outcome was assessed with standard scales between 18 months and 3 years after presentation. A history consistent with viral infection was given in 17 children but laboratory evidence of viral infection was found in only 7 (7/17). In 18 out of 21 children, an elevated CSF: serum albumin ratio indicative of impairment of the blood,CSF and blood,brain barriers was detected at some stage of the illness. In 14 of the 15 children with a raised immunoglobulin G index, and in 12 of the 14 children where the CSF was positive for oligoclonal bands, this was preceded by, or was observed at the same time as, an abnormal albumin ratio. Sixteen children (16/18) had elevated IFN-, levels in serum, or CSF, or in both. We conclude that these findings indicate an initial disruption of the blood-brain barrier followed by intrathecal antibody production by activated lymphocytes, clonally restricted to a few antigens. This is the first in vivo study to show this as an important pathogenetic mechanism of encephalitis in children. Poor outcome was associated with young age, a deteriorating electroencephalogram pattern from grade 1 to grade 2, and the degree of blood-brain barrier impairment, particularly when prolonged, but not with Glasgow Coma Scale score. The persistence of IFN-, was associated with a good prognosis. [source] The Validity of Using Multiple Imputation for Missing Out-of-hospital Data in a State Trauma RegistryACADEMIC EMERGENCY MEDICINE, Issue 3 2006Craig D. Newgard MD Objectives: To assess 1) the agreement of multiply imputed out-of-hospital values previously missing in a state trauma registry compared with known ambulance values and 2) the potential impact of using multiple imputation versus a commonly used method for handling missing data (i.e., complete case analysis) in a typical multivariable injury analysis. Methods: This was a retrospective cohort analysis. Multiply imputed out-of-hospital data from 1998 to 2003 for four variables (intubation attempt, Glasgow Coma Scale score, systolic blood pressure, and respiratory rate) were compared with known values from probabilistically linked ambulance records using measures of agreement (,, weighted ,, and Bland,Altman plots). Ambulance values were assumed to represent the "true" values for all analyses. A hypothetical multivariable regression model was used to demonstrate the impact (i.e., bias and precision of model results) of handling missing out-of-hospital data with multiple imputation versus complete case analysis. Results: A total of 6,150 matched ambulance and trauma registry records were available for comparison. Multiply imputed values for the four out-of-hospital variables demonstrated fair to good agreement with known ambulance values. When included in typical multivariable analyses, multiple imputation increased precision and reduced bias compared with using complete case analysis for the same data set. Conclusions: Multiply imputed out-of-hospital values for intubation attempt, Glasgow Coma Scale score, systolic blood pressure, and respiratory rate have fair to good agreement with known ambulance values. Multiple imputation also increased precision and reduced bias compared with complete case analysis in a typical multivariable injury model, and it should be considered for studies using out-of-hospital data from a trauma registry, particularly when substantial portions of data are missing. [source] Pain Scores Improve Analgesic Administration Patterns for Trauma Patients in the Emergency DepartmentACADEMIC EMERGENCY MEDICINE, Issue 3 2004Paul A. Silka MD Abstract Objective: To determine the efficacy of pain scores in improving pain management practices for trauma patients in the emergency department (ED). Methods: A prospective, observational study of analgesic administration to trauma patients was conducted over a nine-week period following educational intervention and introduction of verbal pain scores (VPSs). All ED nursing and physician staff in an urban Level I trauma center were trained to use the 0,10 VPS. Patients younger than 12 years old, having a Glasgow Coma Scale score (GCS) <8, or requiring intubation were excluded from analysis. Demographics, mechanism of injury, vital signs, pain scores, and analgesic data were extracted from a computerized ED database and patients' records. The staff was blinded to the ongoing study. Results: There were 150 patients studied (183 consecutive trauma patients seen; 33 patients excluded per criteria). Pain scores were documented for 73% of the patients. Overall, 53% (95% confidence interval [CI] = 45% to 61%) of the patients received analgesics in the ED. Of the patients who had pain scores documented, 60% (95% CI = 51% to 69%) received analgesics, whereas 33% (95% CI = 18% to 47%) of the patients without pain scores received analgesics. No patient with a VPS < 4 received analgesics, whereas 72% of patients with a VPS > 4 and 82% with a VPS > 7 received analgesics. Mean time to analgesic administration was 68 minutes (95% CI = 49 to 87). Conclusions: Pain assessment using VPS increased the likelihood of analgesic administration to trauma patients with higher pain scores in the ED. [source] Testing the outcome score of spontaneous intracerebral haemorrhage in haemodialysis patientsINTERNAL MEDICINE JOURNAL, Issue 10 2009B.-R. Huang Abstract The aim of this study is to determine the predictive value of the spontaneous intracerebral haemorrhage (ICH) outcome score (which we described previously) in haemodialysis (HD) patients who develop spontaneous ICH. The validation cohort consisted of all HD patients with spontaneous ICH presenting to Chang Gung Memorial Hospital in Taiwan during 2005,2007. The data were collected from one hospital and prospectively analysed, and the predictive model was tested using an external validation dataset. The prognostic factors were confirmed by chi-squared testing. We calculated the 30-day mortality in different groups of the validation cohort divided according to outcome score and tested the predictive value of the outcome score. The overall mortality rate was 52.6% in 38 HD patients. The originally identified prognostic factors were Glasgow Coma Scale score, age ,70 years, systolic blood pressure <130 or ,200 mmHg, ICH volume ,30 mL, presence of intraventricular haemorrhage and serum glucose ,8.8 mmol/L. All but one (serum glucose ,8.8 mmol/L (P= 0.07)) were subsequently found to be associated with 30-day mortality. In patients scoring 6 and 7, mortality was 100%, but in patients scoring 0, it was only 11.1%. The 30-day mortality in the validation cohort increased steadily with score and had good predictive value (correlation coefficient = 0.986, P < 0.001). Similar results in two different cohorts indicate that the ICH outcome score is a reliable outcome measure. [source] Acute confusional state after designer tryptamine abusePSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 2 2007MASANARI ITOKAWA md Abstract A 23-year-old Japanese woman was brought to the emergency department about 6.5 h after taking liquid and later a half tablet purchased on the street. About 4.5 h prior to presentation, she displayed excited and disorganized behavior. On examination, she was not alert or oriented, with a Glasgow Coma Scale score of 13, did not answer any questions from doctors while smirking and looking around restlessly, and sometimes exhibited echolalia, imitating the speech of doctors. She was given intravenous infusion of fluid for 8 h, then discharged. Gas chromatography-mass spectrometry of urine revealed 5-methoxy-diisopropyltryptamine, 5-methoxy-N-methyltryptamine and an unidentified tryptamine. Identifying chemical products based solely on information of users is insufficient, and urinalysis is necessary in cases potentially involving designer drugs. [source] Perfusion computed tomography in the acute phase of mild head injury: Regional dysfunction and prognostic value,ANNALS OF NEUROLOGY, Issue 6 2009Zwany Metting MD Objective Traumatic brain injury is a major cause of disability and death. Most patients sustain a mild head injury with a subgroup that experiences disabling symptoms interfering with return to work. Brain imaging in the acute phase is not predictive of outcome, as 20% of noncontrast computed tomographic (CT) scans on admission is normal in patients with a suboptimal outcome. The aim of this study was to perform perfusion CT imaging in the acute phase of mild head injury in patients without intracranial abnormalities on the noncontrast CT, to assess whether these patients had cerebral perfusion abnormalities. Furthermore, the relation between perfusion CT parameters and severity of head injury and outcome was evaluated. Methods In patients with mild head injury and normal noncontrast CT, perfusion CT was performed directly after admission. The perfusion data were compared with data of 25 healthy control subjects. Outcome was determined 6 months after injury with the extended Glasgow Coma Outcome Scale score and return to work. Results Seventy-six patients were included. In patients with a decreased Glasgow Coma Scale score, a significant decrease of cerebral blood flow and cerebral blood volume was detected in the frontal and occipital gray matter. In logistic regression analyses, decreased cerebral blood flow and cerebral blood volume in the frontal lobes predicted worse outcome according to the extended Glasgow Coma Outcome Scale score. CT perfusion parameters did not predict return to work. Interpretation In the acute phase of mild head injury, disturbed cerebral perfusion is seen in patients with normal noncontrast CT correlating with severity of injury and outcome.

Renzulli Background: Non-operative management (NOM) of blunt splenic injuries is nowadays considered the standard treatment. The present study identified selection criteria for primary operative management (OM) and planned NOM. Methods: All adult patients with blunt splenic injuries treated at Berne University Hospital, Switzerland, between 2000 and 2008 were reviewed. Results: There were 206 patients (146 men) with a mean(s.d.) age of 38·2(19·1) years and an Injury Severity Score of 30·9(11·6). The American Association for the Surgery of Trauma classification of the splenic injury was grade 1 in 43 patients (20·9 per cent), grade 2 in 52 (25·2 per cent), grade 3 in 60 (29·1 per cent), grade 4 in 42 (20·4 per cent) and grade 5 in nine (4·4 per cent). Forty-seven patients (22·8 per cent) required immediate surgery. Transfusion of at least 5 units of red cells (odds ratio (OR) 13·72, 95 per cent confidence interval 5·08 to 37·01), Glasgow Coma Scale score below 11 (OR 9·88, 1·77 to 55·16) and age 55 years or more (OR 3·29, 1·07 to 10·08) were associated with primary OM. The rate of primary OM decreased from 33·3 to 11·9 per cent after the introduction of transcatheter arterial embolization in 2005. Overall, 159 patients (77·2 per cent) qualified for NOM, which was successful in 143 (89·9 per cent). The splenic salvage rate was 69·4 per cent. In multivariable analysis age at least 40 years was the only factor independently related to failure of NOM (OR 13·58, 2·76 to 66·71). Conclusion: NOM of blunt splenic injuries has a low failure rate. Advanced age is independently associated with an increased failure rate. Copyright © 2010 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd. [source] Performance of Severity of Illness Scoring Systems in Emergency Department Patients with InfectionACADEMIC EMERGENCY MEDICINE, Issue 8 2007Michael D. Howell MD ObjectivesTo validate the Mortality in Emergency Department Sepsis (MEDS) score, the Confusion, Urea nitrogen, Respiratory rate, Blood pressure, 65 years of age and older (CURB-65) score, and a modified Rapid Emergency Medicine Score (mREMS) in patients with suspected infection. MethodsThis was a prospective cohort study. Adult patients with clinically suspected infection admitted from December 10, 2003, to September 30, 2004, in an urban emergency department with approximately 50,000 annual visits were eligible. The MEDS and CURB-65 scores were calculated as originally described, but REMS was modified in neurologic scoring because a full Glasgow Coma Scale score was not uniformly available. Discrimination of each score was assessed with the area under the receiver operating characteristics curve (AUC). ResultsOf 2,132 patients, 3.9% (95% confidence interval [CI] = 3.1% to 4.7%) died. Mortality stratified by the MEDS score was as follows: 0,4 points, 0.4% (95% CI = 0.0 to 0.7%); 5,7 points, 3.3% (95% CI = 1.7% to 4.9%); 8,12 points, 6.6% (95% CI = 4.4% to 8.8%); and ,13 points, 31.6% (95% CI = 22.4% to 40.8%). Mortality stratified by CURB-65 was as follows: 0 points, 0% (0 of 457 patients); 1 point, 1.6% (95% CI = 0.6% to 2.6%); 2 points, 4.1% (95% CI = 2.3% to 6.0%); 3 points, 4.9% (95% CI = 2.8% to 6.9%); 4 points, 18.1% (95% CI = 11.9% to 24.3%); and 5 points, 28.0% (95% CI = 10.4% to 45.6%). Mortality stratified by the mREMS was as follows: 0,2 points, 0.6% (95% CI = 0 to 1.2%); 3,5 points, 2.0% (95% CI = 0.8% to 3.1%); 6,8 points, 2.3% (95% CI = 1.1% to 3.5%); 9,11 points, 7.1% (95% CI = 4.2% to 10.1%); 12,14 points, 20.0% (95% CI = 12.5% to 27.5%); and ,15 points, 40.0% (95% CI = 22.5% to 57.5%). The AUCs were 0.85, 0.80, and 0.79 for MEDS, mREMS, and CURB-65, respectively. ConclusionsIn this large cohort of patients with clinically suspected infection, MEDS, mREMS, and CURB-65 all correlated well with 28-day in-hospital mortality. [source] Predictive value of clinical and radiological findings in inflicted traumatic brain injuryACTA PAEDIATRICA, Issue 9 2010Pilvi Ilves Abstract Aims:, The aim of this study is to evaluate the value of early radiological investigations in predicting the long-term neurodevelopmental outcome of infants with inflicted traumatic brain injury (ITBI). Methods:, Clinical and radiological investigations of 24 infants with ITBI were performed during the acute phase of injury (1,3 days), and during the early (4 days up to 3 months) and late (>9 months) postinjury phases. The clinical outcome in survivors (n = 22) was based on the Rankin Disability Scale and the Glasgow Outcome Score. Results:, Five out of 24 infants (21%) had a poor neurodevelopmental outcome (death and severe disability), 17 infants (71%) had different developmental problems and 2 infants were normal at the mean age of 62 (54,70) (95% CI) months. A low initial Glasgow Coma Scale score of 8 or below [p < 0.05, OR 13.0 (1.3,133.3)], the development of brain oedema [p < 0.005, OR 13.0 (1.6,773)], focal changes in the basal ganglia during the acute phase [p < 0.01, OR 45 (2.1,937.3)], the development of new intracerebral focal changes early postinjury [p < 0.05, OR 24.1(1.0,559.1)], a decrease in white matter [p < 0.01, OR 33 (1.37,793.4)] and the development of severe atrophy before 3 months postinjury [p < 0.05, OR 24 (11.0,559.1)] were significantly correlated with a poor neurodevelopmental outcome. Conclusions:, Early clinical and radiological findings in ITBI are of prognostic value for neurodevelopmental outcome. [source] | ||||||||||
