Beta-blocker use is associated with improved outcomes in adult trauma patients.

Background: Beta-adrenoreceptor blocker (beta-blocker) therapy may improve outcomes in surgical patients by decreasing cardiac oxygen consumption and hypermetabolism. Because beta-blockers can lower the systemic blood pressure and cerebral perfusion pressure, there is concern regarding their use in patients with head injury. However, beta-blockers may protect beta-receptor rich brain cells by attenuating cerebral oxygen consumption and metabolism.

Impact of an inpatient rehabilitation facility on functional outcome and length of stay of burn survivors.

This study reviewed the use of an inpatient rehabilitation unit for burn survivors. We hypothesized that adult burn patients admitted earlier to inpatient rehabilitation have an equal or better functional outcome than those remaining in acute burn center for rehabilitation care. Functional Independence Measure (FIM) data were prospectively collected on our burn center admissions dating January 2002 to August 2003.

Bronchoalveolar lavage in diagnosis of ventilator-associated pneumonia in patients with burns.

Ventilator-associated pneumonia (VAP) remains a major cause of morbidity and mortality for patients with burns. In nonburn populations, bronchoalveolar lavage (BAL) excludes other pathology such as systemic inflammatory response syndrome. We hypothesized that BAL would decrease our false-positive VAP rate.

Blunt splenic injury: operation versus angiographic embolization.

Background: Splenic injuries, like other blunt traumatic injuries, are increasingly treated with non-operative management. Angiographic embolization (AE) has emerged as an alternative modality for treatment of splenic injuries. We hypothesized that splenic embolization would lead to equivalent, if not improved, outcomes in terms of mortality, total costs, complications, and duration of stay.

Trends in burn resuscitation: shifting the focus from fluids to adequate endpoint monitoring, edema control, and adjuvant therapies.

Bum shock is a complex process involving a series of intertwined physiologic responses to injury that require more rigorous intervention than simply a change in fluid tonicity, fluid composition, or fluid resuscitation volume. Controversy ensues over monitoring techniques and resuscitation goals, in part because the identification of true markers of perfusion is clouded by intradependence of endpoints on other metabolic processes. The persistence of cellular hypoperfusion in patients who have been deemed adequately resuscitated by global indices supports the growing realization that failure of conventional endpoint-monitoring strategies to detect compensated bum shock can lead to significant organ injury from SIRS or MODS.

Beta-blocker use is associated with improved outcomes in adult burn patients.

Background: There is no direct evidence that beta-blockers improve mortality in burn victims. Beta-blockers attenuate hypermetabolic states in burned children, and perioperative use in elective adult cases has beneficial effects, which suggests that beta-blockers may also improve burn outcomes. However, beta-blockers decrease cardiac output and may decrease oxygen delivery, and theoretically may increase mortality.

Normal D-dimer levels do not exclude thrombotic complications in trauma patients.

Background: Deep venous thrombosis (DVT) and pulmonary embolism (PE) are common complications in trauma patients. These diagnoses can be difficult and expensive to make. Recent studies report that a negative D-dimer test excludes thrombotic complications.

Does bronchoalveolar lavage enhance our ability to treat ventilator-associated pneumonia in a trauma-burn intensive care unit?

Background: Recent literature supports the notion that bronchoalveolar lavage (BAL) in ventilated trauma patients may improve our ability to diagnose and treat ventilator-associated pneumonia (VAP). We hypothesized that BAL would decrease the number of cases of VAP diagnosed and impact our antibiotic use and ventilator days.

Methods: Prospective data on all infectious complications were collected for patients admitted to the trauma-burn service for the year 2001.

The utility of D-dimer levels in screening for thromboembolic complications in burn patients.

Recent studies confirm that thromboembolic complications in burn patients are higher than previously reported. Swelling, pain, and erythema are not useful indicators of deep venous thrombosis (DVT) in burned extremities. We propose that D-dimer levels may be useful in determining which patients would benefit from further screening for DVT.

Hospital cost is reduced by motorcycle helmet use.

Background: The purpose of this study was to identify the impact of motorcycle helmet use on patient outcomes and cost of hospitalization, in a state with a mandatory helmet law.

Methods: Patients admitted after motorcycle crashes from July 1996 to October 2000 were reviewed, including demographics, Injury Severity Score, length of stay, injuries, outcome, helmet use, hospital cost data, and insurance information. Statistical analysis was performed comparing helmeted to unhelmeted patients using analysis of variance, Student's test, and regression analysis.

The need for early angiographic embolization in blunt liver injuries.

Background: Although nonoperative management of blunt liver injury (BLI) has become standard practice, adjuncts to nonoperative therapy, such as angiographic embolization, have not been well characterized.

Methods: Patients with BLI were retrospectively identified at our American College of Surgeons-verified Level I trauma center from January 1997 through February 2001. Patients were stratified into four groups: those who received angiographic embolization (AE) as an early intervention when BLI was initially diagnosed (EARLY-AE); those who underwent AE after liver-related operation or later in the hospital course (LATE-AE); those treated with operation only (OR-ONLY); and nonoperative patients who also did not undergo AE (NO-OR).

Burn centers should be involved in prevention of occupational electrical injuries.

Electrical injuries are uncommon, comprising 10% of our regional burn center admissions during a 9-year period. The purpose of this study was to determine the incidence, type, and location of occupation-related electrical injuries in an attempt to focus our injury prevention and outreach efforts. We retrospectively reviewed the medical records of patients with electrical injuries admitted to our burn center from January 1992 through March 2000, with focused analysis on those patients admitted with occupation-related electrical injuries.

Venous thrombosis incidence in burn patients: preliminary results of a prospective study.

There are few prospective data on the incidence of deep venous thrombosis (DVT) in burn patients. In an on-going prospective study, hospitalized burn patients 18 years or older with an expected hospital length of stay more than 72 hours were imaged with baseline venous duplex ultrasound of all extremities within the first 48 hours after admission and weekly until discharge. Patient demographics and clinical risk factors for DVT were assessed.

Initial resuscitation after burn injury: therapies, strategies, and controversies.

Thermal injury disrupts normal hemostasis and sets off a cascade of events: cellular alterations and release of inflammatory mediators cause hypovolemic and cellular shock. Fluid resuscitation in burn injuries has been in use for more than a century, and much research has been devoted to development of resuscitation formulas and appropriate choice of fluid. Parameters for adequate monitoring of resuscitation are greatly debated.
