Unplanned endotracheal extubation (UEE) is a common complication in medical intensive care units but very little data about UEE in surgical populations are available. Our hypothesis is that the surgical intensive care unit (SICU) population requires reintubation less frequently compared with the medical intensive care unit population. We prospectively gathered data on patients in a SICU in an attempt to identify the incidence of UEE and to study the need for reintubation after UEE. ⋯ A total of 85% of patients who self-extubate during the weaning process did not require reintubation in our study. Those who have an FiO2 >50%, a lower PaO2/FiO2 ratio, had UEE occur by accident, or were not being weaned when UEE occurred required reintubation more frequently. These data suggest that some of our SICU patients are intubated longer than necessary, which may translate into more ventilator related complications, longer ICU stays and increased cost.

To determine the utility of near-infrared spectroscopy in the diagnosis of lower extremity compartment syndrome (CS). ⋯ Near-infrared spectroscopy-derived StO2 values in the lower extremities of trauma patients with CS were diminished relative to the control patients and usually normalized after fasciotomy. Near-infrared spectroscopy evaluation may offer a rapid, noninvasive method of assessing extremities at risk for CS.

Intolerance of enteral nutrition interrupts caloric balance and increases hospital costs. This study proposes that enteral feeding by percutaneous endoscopic gastrojejunostomy (PEGJ) provides continuous uninterrupted nutrition with greater consistency than percutaneous endoscopic gastrostomy (PEG). ⋯ This study suggests that enteral nutrition delivered by means of PEGJ is better tolerated than enteral nutrition delivered by means of PEG in trauma patients with no abdominal conditions that preclude percutaneous feeding tube placement.

The circumstances of failure for nonoperative management of blunt traumatic brain injury have been poorly defined. In this study, all trauma patients identified over a 12-year period with progression of neurologic injury requiring craniotomy were retrospectively reviewed. ⋯ Of the variables investigated, only anatomic location of injury was found to be predictive of early failure of nonoperative management. Frontal intraparenchymal hematomas are particularly prone to early failure. Clinical examination and intracranial pressure monitoring are equally important in detecting failure and should be an integral part of nonoperative management.

The potential to modulate the inflammatory response has renewed interest in hypertonic saline (HTS) resuscitation of injured patients. However, the effect of the timing of HTS treatment with respect to polymorphonuclear neutrophil (PMN) priming and activation remains unexplored. We hypothesized that HTS attenuation of PMN functions requires HTS exposure before priming and activation. ⋯ The timing of HTS is a key variable in the attenuation of PMN cytotoxic functions. Maximal attenuation of cytotoxicity is achieved before priming, whereas HTS exposure after activation augments cytotoxicity.
