Randomized Controlled Trial Comparative Study Clinical Trial
Effects of an immune-enhancing diet in critically injured patients.
To determine the effects of an immune-enhancing experimental diet (XD = supplemental arginine, trace elements, and increased omega-3 fatty acids) versus standard diet (SD), on immune cell function and clinical outcome of critically injured patients. ⋯ The exact role and timing for diets with immune-enhancing effects has yet to be defined.

Comparative Study
Right ventricular volumes overestimate left ventricular preload in critically ill patients.
Studies have shown right ventricular end-diastolic volume (RVEDV) to be a more accurate estimate of left ventricular preload than pulmonary artery wedge pressure. We prospectively evaluated the ability of RVEDV to predict left ventricular end-diastolic volume (LVEDV) in critically ill patients. ⋯ RVEDV from the RF Swan markedly overestimated left ventricular preload. If RVEDV is used as an absolute value for determining preload, patients may be underresuscitated. Transesophageal echocardiography in conjunction with RF Swan can be used to more accurately determine preload and cardiac performance than RF Swan alone in critically ill patients.

Open pelvic fractures represent one of the most devastating injuries in orthopedic trauma. The purpose of this study was to document the injury characteristics, complications, mortality, and long-term, health-related quality of life outcomes in patients with open pelvic fractures. ⋯ Patients with open pelvic fractures often survive, need to be treated with massive blood transfusions, and often require a colostomy. They are frequently left with chronic pain and residual disabilities in physical functioning and physical roles, and many remain unemployed years after injury.

Recalcitrant coagulopathy "the bloody vicious cycle," produces the majority of deaths after torso trauma. A model predicting this life-threatening complication may facilitate clinical decision-making. ⋯ Postinjury life-threatening coagulopathy in the seriously injured requiring massive transfusion is predicted by persistent hypothermia and progressive metabolic acidosis.

Recently, invasive intensive care unit monitoring of cerebral oxygenation has become feasible. The purpose of this study was to investigate the effects of standard therapeutic interventions used in the treatment of intracranial hypertension on cerebral oxygenation and other physiologic parameters in comatose patients. ⋯ A CPP > 60 mm Hg emerges as the crucial factor guaranteeing sufficient brain oxygenation. Any intervention used to further elevate CPP does not improve cerebral oxygenation, to the contrary, forced hyperventilation even bears the risk of inducing brain ischemia.
