Selected AbstractsThe Efficacy of Esmolol versus Lidocaine to Attenuate the Hemodynamic Response to Intubation in Isolated Head Trauma PatientsACADEMIC EMERGENCY MEDICINE, Issue 1 2001M. Andrew Levitt DO Abstract. Objective: To assess the effect of esmolol vs lidocaine to attenuate the detrimental rise in heart rate and blood pressure during intubation of patients with isolated head trauma. Methods: This was a prospective, double-blind, randomized study, performed at an urban, county teaching emergency department. Participants were 30 patients with isolated head trauma. Each underwent a standardized intubation protocol including esmolol or lidocaine, both at 2 mg/kg. Results: Esmolol was used in 16 patients and lidocaine in 14. Mechanisms of injury included 12 assaults, 6 motor vehicle collisions, 6 falls, 4 auto-vs-pedestrian crashes, and 2 bicycle incidents. Mean ethanol level was 0.116 ± 0.133 SD (range 0-0.482). Mean Glasgow Coma Scale (GCS) score was 7.9 ± 4.0 SD. Cranial computed tomography (CT) hemorrhagic findings included 9 subdural/epidural hematomas, 6 cortex hemorrhages, and 2 multi-hemorrhages. Eleven patients received surgical intervention: 9 patients received a craniotomy, and 2 a ventricular catheter. The 2-minute time interval around intubation was used to assess each drug's efficacy. The mean difference change between groups for heart rate was 4.0 beats/min (95% CI = -17.7 to 9.7 beats/min), for systolic blood pressure was 1.3 mm Hg (95% CI = -27.8 to 30.4 mm Hg), and for diastolic blood pressure was 2.6 mm Hg (95% CI = -27.1 to 21.9 mm Hg). The power of this study was 90% to detect a 20-beat/min difference in heart rate, a 35-mm Hg difference in systolic blood pressure, and a 20-mm Hg difference in diastolic blood pressure. Conclusions: Esmolol and lidocaine have similar efficacies to attenuate moderate hemodynamic response to intubation of patients with isolated head trauma. [source] The Prognostic Value of the Modified Glasgow Coma Scale in Head Trauma in DogsJOURNAL OF VETERINARY INTERNAL MEDICINE, Issue 6 2001Simon R. Platt A clinical coma scale modified from the Glasgow Coma Scale used for humans has been suggested as a useful predictor of outcome in the head trauma patient. The objective of this study was to correlate the modified Glasgow Coma Scale (MGCS) score of dogs with head trauma with their probability of survival. Thirty-eight dogs with head trauma were selected and retrospectively evaluated. The information retrieved from the medical record of each dog included signalment, body weight, cause of head trauma, MGCS, presence of concurrent neck pain, and outcome (dead or alive) after 48 hours. Logistic regression was used to model survival in the 1st 48 hours as a function of MGCS, gender, weight, and calvarial fractures. The MGCS ranged from 5 to 18. Seven dogs died within 48 hours of the head trauma. The MGCS could predict the probability of survival in the 1st 48 hrs after head trauma with 50% probability in a patient with a score of 8. Gender, weight, and presence of skull fractures did not predict survival. In conclusion, the MGCS is a useful index for prediction of outcome in dogs with head trauma. [source] Peripheral blood picture following mild head trauma in childrenPEDIATRICS INTERNATIONAL, Issue 3 2008Bulent Alioglu Abstract Background: The aim of the present study was to investigate changes in peripheral white blood cell, and differential counts following mild head trauma in a pediatric population. Methods: Fifty-one patients (mean age, 79 ± 62 months) with mild head trauma (Glasgow Coma Scale [GCS] score 15) who were admitted to the emergency department, were studied. Two blood specimens were collected from each patient, one on arrival and one after 24 h at the emergency department. Complete blood count was performed using a hemocytometer and the absolute cell counts for each sample were calculated after examination of peripheral smear. Results: No patient developed any complication during the hospital stay or after discharge. Significant differences were found for white blood cell, neutrophil, and immature cell counts just after and 24 h after trauma (P = 0.047, 0.039 and 0.009, respectively). Conclusions: Mild head trauma may cause an increase in white blood cell, neutrophil and band counts in children just after trauma. In a child with a mild head trauma, who is asymptomatic, with GCS score of 15 and absence of risk factors, and without clinical deterioration, complete blood cell count may be omitted from laboratory workup. But a prospective randomized study comparing mild head trauma patients with good and bad clinical outcome is needed to draw a definite conclusion.

Abrahamson PhD Elevations in ,-amyloid peptide (A,) levels after traumatic brain injury (TBI) may confer risk for developing Alzheimer's disease in head trauma patients. We investigated the effects of simvastatin, a 3-hydroxy-3-methylglutaryl-CoA reductase inhibitor, on hippocampal A, burden in a clinically relevant head injury/intervention model using mice expressing human A,. Simvastatin therapy blunted TBI-induced increases in A,, reduced hippocampal tissue damage and microglial activation, and improved behavioral outcome. The ability of statins to reduce post-injury A, load and ameliorate pathological sequelae of brain injury makes them potentially effective in reducing the risk of developing Alzheimer's disease in TBI patients.
