BACKGROUND For patients with adhesive small bowel obstruction (ASBO), early surgery after a failed trial of nonoperative treatment can improve outcome. However, deciding which patients require early surgery is difficult, given the lack of specific clinical or radiographic signs. The study goals were to identify clinical and computed tomography (CT)(More)
High ratios of Plasma to Packed Red Blood Cells (FFP:PRBC) improve survival in massively transfused trauma patients. We hypothesized that non-trauma patients also benefit from this transfusion strategy. Non-trauma patients requiring massive transfusion from November 2003 to September 2011 were reviewed. Logistic regression was performed to identify(More)
BACKGROUND Intracranial pressure (ICP) monitoring is a standard of care in severe traumatic brain injury when clinical features are unreliable. It remains unclear, however, whether elevated ICP or decreased cerebral perfusion pressure (CPP) predicts outcome. METHODS This is a prospective observational study of patients sustaining severe blunt head injury,(More)
Subtotal cholecystectomy (SC) is an alternative to open total cholecystectomy (OTC) when variable anatomy or other intraoperative findings preclude safe dissection of Calot's triangle. The objective of this study was to compare the outcomes between SC and OTC in patients with complicated cholecystitis, cases that could not be completed with the original(More)
BACKGROUND During subclavian vein catheterization, a potential, but rare, hazard is the phrenic nerve injury, which compromises respiratory function. We conducted a cadaver study focused on the possible anatomical relationships between the subclavian vein and the phrenic nerve. METHODS Forty-two adult cadavers (84 heminecks) were dissected. Special(More)
BACKGROUND Incidental pneumomediastinum is a common radiologic finding following blunt thoracic injury; however, the clinical significance of pneumomediastinum on screening imaging is poorly defined (Curr Probl Surg. 2004;41(3):211-380; Injury. 2010;41(1):40-43). The purpose of this study was to define the incidence of aerodigestive injuries in patients(More)
BACKGROUND Aspiration events (AEs) are a well-recognized complication in trauma patients and have traditionally been considered a risk factor for pneumonia. Despite this, there is no consensus on the incidence or clinical significance of AE in the trauma population. METHODS All patients admitted as trauma team activations at our Level I trauma center who(More)
BACKGROUND The traditional theory that pulmonary emboli (PE) originate from the lower extremity has been challenged. METHODS All autopsies performed in Los Angeles County between 2002 and 2010 where PE was the cause of death were reviewed. RESULTS Of the 491 PE deaths identified, 36% were surgical and 64% medical. Venous dissection for clots was(More)
Ventricular arrhythmias (VAs) are common pediatric rhythm disorders requiring comprehensive laboratory evaluation. Although usually idiopathic, implying a benign character and favorable prognosis, the initial clinical approach is still not established in all cases. Considering their prognostic significance, exercise-induced (precipitated or aggravated) VAs(More)
Discontinuity of the bowel following intestinal injury and resection is a common practice in damage control procedures for severe abdominal trauma. However, there are concerns that complete occlusion of the bowel, especially in the presence of hypotension or edema that may result in ischemic bowel changes or increase bacterial or toxin translocation.
