The high prevalence of ventilator-associated pneumonia (VAP) in trauma patients has been reported in the literature, but the reasons for this observation remain unclear. We hypothesize that trauma factors play critical roles in VAP etiology. ⋯ It is time to redefine VAP in trauma patients based on the effect of rib fractures, pulmonary contusions, and failed prehospital intubations. The Centers for Disease Control and Prevention definition of VAP needs to be modified to reflect the effect of trauma factors in the etiology of trauma-associated pneumonia.

"Blush," defined as a focal area of contrast pooling within a hematoma, is frequently encountered in patients with severe blunt torso trauma. Contemporary clinical practice guidelines recommend the use of angiography with embolization in all hemodynamically stable patients with evidence of active extravasation. Patients presenting with blush visualized on computed tomography (CT), but not demonstrated on subsequent angiography, present a challenging clinical dilemma. The purpose of this study was to study the natural course of patients with this blush disparity between CT and angiography. ⋯ CT imaging has enhanced our ability to detect contrast extravasation after injury, and evidence of blush on CT suggests the presence of active hemorrhage. This analysis suggests that in clinical situations in which CT blush is noted secondary to blunt trauma to the spleen or liver, a negative angiogram still carries a significant risk of recurrent hemorrhage; consideration for empiric embolization at the time of the initial procedure even in the absence of blush on angiographic evaluation is thus warranted. Prospective studies are needed to validate these findings and to assess the utility of this clinical paradigm.

Surgical wound classification (SWC) is a component of surgical site infection risk stratification. Studies have demonstrated that SWC is often incorrectly documented. This study examines the accuracy of SWC after implementation of a multifaceted plan targeted at accurate documentation. ⋯ Implementation of a multifaceted approach improved accuracy of documented SWC.

Obesity's influence on postoperative complications in either laparoscopic ventral hernia repair (LVHR) or open ventral hernia repair (OVHR) has yet to be defined. Although 30-day postoperative complications increase with higher body mass index (BMI), we propose LVHR minimizes surgical site infections (SSIs) and surgical site occurrences (SSOs) for given BMI categories. ⋯ Obese patients are over-represented in VHRs. Thirty-day postoperative wound complications increase with higher BMI. LVHR minimizes both SSIs and SSOs, especially in higher obesity classes.

The effect of intracranial pressure (ICP) monitoring on mortality after severe traumatic brain injury (sTBI) remains unclear. We hypothesized that ICP monitoring would not be associated with improved survival in patients with sTBI. ⋯ ICP monitoring is associated with improved survival in adult patients with sTBI. In addition, significant variability exists in the use of ICP monitoring among patients with sTBI.
