Prevalence of sleep apnea in morbidly obese patients who presented for weight loss surgery evaluation: more evidence for routine screening for obstructive sleep apnea before weight loss surgery.
The incidence of obstructive sleep apnea has been underestimated in morbidly obese patients who present for evaluation for weight loss surgery. This retrospective study shows that the incidence of obstructive sleep apnea in this patient population is greater than 70 per cent and increases in incidence as the body mass index increases. Obstructive sleep apnea (OSA) is a common comorbidity in obese patients who present for evaluation for gastric bypass surgery. ⋯ Those with a BMI 60 kg/m2 or greater, the prevalence of OSA rose to 95 per cent. The incidence of sleep apnea in patients presenting for weight loss surgery was greater than 70 per cent in our study. Patients presenting for weight loss surgery should undergo a formal sleep study to diagnose OSA before bariatric surgery.

Controlled Clinical TrialA protocol for the rapid normalization of INR in trauma patients with intracranial hemorrhage on prescribed warfarin therapy.
Trauma patients on prescribed warfarin therapy sustaining intracranial hemorrhage can be difficult to manage. Rapid normalization of coagulopathy is imperative to operative intervention and may affect outcomes. To identify and expedite warfarin reversal, we designed a protocol to administer a prothrombin complex concentrate. ⋯ Protocol patients had improved times to normalization of INR (331.3 vs 737.8 minutes, P = 0.048), number of patients with reversal of coagulopathy (73.2% vs 50.9%, P = 0.026), and time to operative intervention (222.6 vs 351.3 minutes, P = 0.045) compared with control subjects. There were no differences in intensive care unit (ICU) days, hospital days, or mortality. The Proplex T protocol increased the number of patients who received prothrombin complex concentrate, provided rapid normalization of INR, and improved time to operative intervention.

Taser devices were introduced in 1974 and are increasingly used by law enforcement agencies. Taser use theoretically reduces the risk of injury and death by decreasing the use of lethal force. We report a spectrum of injuries sustained by four patients subdued with Taser devices. ⋯ However, individuals may be exposed to the potential for significant injury. These devices represent a new mechanism for potential injury. Trauma surgeons and law enforcement agencies should be aware of the potential danger of significant head injuries as a result of loss of neuromuscular control.

How we die: the impact of nonneurologic organ dysfunction after severe traumatic brain injury.
Although nonneurologic organ dysfunction (NNOD) has been shown to significantly affect mortality in subarachnoid hemorrhage, the contribution of NNOD to mortality after severe traumatic brain injury (TBI) has yet to be defined. We hypothesized that NNOD has a significant impact on mortality after severe TBI. The trauma registry was queried for all patients admitted between January 2004 and December 2004 who died during their initial hospitalization after severe TBI (head Abbreviated Injury Score 3 or greater). ⋯ NNOD contributes to approximately two-thirds of all deaths after severe TBI. These complications occur early and are seen even among those with isolated head injuries. These findings demonstrate the impact of the extracranial manifestations of severe TBI on overall mortality and highlight potential areas for future intervention and research.

Blunt liver injury in children and adults: is there really a difference?
Hepatic injuries are increasingly managed nonoperatively with the availability of adjunctive procedures such as angiography, ERCP, and percutaneous drainage. Although extensively discussed in the adult population, little has been reported on outcomes and management of pediatric liver injury. Retrospective review of all patients with blunt liver injuries admitted to an adult Level I trauma center and pediatric trauma center within the same community was performed from 2004 to 2006. ⋯ Adult patients used adjunctive measures as part of their nonoperative management more frequently, but both subsets had similar length of hospital stays and low overall mortality. A higher rate of liver-related mortality was seen in the PED population. Overall, PED patients seemed to sustain fewer liver related complications necessitating invasive procedures despite similar injury patterns.
