Bedside optic nerve sheath diameter ultrasound for the evaluation of suspected pediatric ventriculoperitoneal shunt failure in the emergency department. - Child's nervous system : ChNS : official journal of the International Society for Pediatric Neurosurgery
To determine the feasibility and test characteristics of optic nerve sheath diameter (ONSD) measured by ocular ultrasound as a screening tool for ventriculoperitoneal shunt (VPS) failure.Prospective observational study using a convenience sample of children 6 months to 18 years of age, presenting to an academic pediatric emergency department for evaluation of possible VPS failure between September 2008 and March 2009. ONSD was measured by anterior transbulbar and lateral transbulbar techniques. Mean ONSD was compared between subjects with and without shunt failure, as determined by neurosurgical decision to operate.A total of 39 encounters were completed, including 20 VPS failures. The mean ONSD was 4.5 ± 0.9 and 5.0 ± 0.6 mm among encounters with and without shunt failure (p = 0.03), respectively. The mean ONSD was not statistically different when obtained by the anterior transbulbar vs. the lateral transbulbar approach (4.8 ± 1.0 vs. 4.7 ± 0.8 mm, p = 0.12). ONSD ultrasound had a sensitivity of 61.1 % (95 % CI 35.7-82.7) and specificity of 22.2 % (95 % CI 6.4-47.6 %) for detecting shunt failure in this sample.ONSD ultrasound does not appear to be a useful primary screening tool in emergency department evaluation of VPS failure. There was no difference between the anterior transbulbar approach and the lateral transbulbar approach. Children with VPS in our sample have larger ONSD measurements than in previously reported studies.
Soft tissue infections and emergency department disposition: predicting the need for inpatient admission. - Academic emergency medicine : official journal of the Society for Academic Emergency Medicine
Little empiric evidence exists to guide emergency department (ED) disposition of patients presenting with soft tissue infections. This study's objective was to generate a clinical decision rule to predict the need for greater than 24-hour hospital admission for patients presenting to the ED with soft tissue infection.This was a retrospective cohort study of consecutive patients presenting to a tertiary care hospital ED with diagnosis of nonfacial soft tissue infection. Standardized chart review was used to collect 29 clinical variables. The primary outcome was >24-hour hospital admission (either general admission or ED observation unit), regardless of initial disposition. Patients initially discharged home and later admitted for more than 24 hours were included in the outcome. Data were analyzed using classification and regression tree (CART) analysis and multivariable logistic regression.A total of 846 patients presented to the ED with nonfacial soft tissue infection. After merging duplicate records, 674 patients remained, of which 81 (12%) required longer than 24-hour admission. Using CART, the strongest predictors of >24-hour admission were patient temperature at ED presentation and mechanism of infection. In the multivariable logistic regression model, initial patient temperature (odds ratio [OR] for each degree over 37 degrees C = 2.91, 95% confidence interval [CI] = 1.65 to 5.12) and history of fever (OR = 3.02, 95% CI = 1.41 to 6.43) remained the strongest predictors of hospital admission. Despite these findings, there was no combination of factors that reliably identified more than 90% of target patients.Although we were unable to generate a high-sensitivity decision rule to identify ED patients with soft tissue infection requiring >24-hour admission, the presence of a fever (either by initial ED vital signs or by history) was the strongest predictor of need for >24-hour hospital stay. These findings may help guide disposition of patients presenting to the ED with nonfacial soft tissue infections.
Association between a positive ED FAST examination and therapeutic laparotomy in normotensive blunt trauma patients. - The Journal of emergency medicine
Although a positive FAST (focused assessment with sonography for trauma) examination in hypotensive blunt trauma patients generally suggests the need for emergent laparotomy, this finding's significance in normotensive trauma patients is unclear. We tested the association between a positive FAST and the need for therapeutic laparotomy in normotensive blunt trauma patients. This was a retrospective cohort analysis of consecutive normotensive blunt trauma patients presenting to two trauma centers. The outcome was therapeutic laparotomy. The unadjusted association between a positive FAST and laparotomy was odds ratio (OR) 116 (95% confidence interval [CI] 49.5-273). This association persisted after adjusting for confounding variables (OR 44.6, 95% CI 1.77-1124). Thirty-seven percent of patients with a positive FAST required therapeutic laparotomy vs. 0.5% with a negative FAST. Among normotensive blunt trauma patients, there was a strong association between a positive FAST and the need for therapeutic laparotomy. Very few normotensive patients with a negative FAST required therapeutic laparotomy.
Principles of basic wound evaluation and management in the emergency department. - Emergency medicine clinics of North America
The primary objectives of basic wound management center around promoting optimal wound healing and cosmesis. These objectives may be achieved through the systematic assessment, preparation, and repair of the laceration supplemented with appropriate patient care instructions. The meticulous and methodical management of traumatic wounds described in this article will assist the emergency physician in decreasing overall complication rates and help improve patient satisfaction.
The saliva strip test is an accurate method to determine blood alcohol concentration in trauma patients. - Academic emergency medicine : official journal of the Society for Academic Emergency Medicine
To determine the accuracy of alcohol saliva testing (AST) in trauma patients.Blood alcohol concentration (BAC) was measured by using both AST (QED A350; STC Technologies, Bethlehem, PA) and blood serum levels in 100 trauma patients admitted to the emergency department of an urban Level 1 trauma center.All 41 patients who tested positive for BAC on AST (mean [+/-SD]: 167.9 +/- 16.16; range: 20-350 mg/dL) also tested positive on serum determination (mean: 197.6 +/- 13.79; range: 22-446 mg/dL). Correlation between the two positive tests was significant (0.879, p < 0.001). Of the remaining 61 patients, 59 tested negative on both tests, while two patients with BACs of <30 mg/dL tested negative on the AST. For 18 patients with blood in the oropharynx, there was a correlation of 0.976 (p < 0.001, two-tailed) between serum and AST tests.The AST method of measuring BAC in trauma patients is accurate. Blood in the oral cavity did not appear to affect the accuracy of the test.
