Comparative StudyThromboembolic prophylaxis in blunt traumatic intracranial hemorrhage: a retrospective review.
There are few data in the literature on venous thromboembolic (VTE) prophylaxis for the traumatic population with intracranial hemorrhage (ICH). We reviewed our institutional experience and compared the incidence of deep vein thrombosis and pulmonary embolism in patients with ICH receiving either early prophylaxis (< 72 hours from admission) or late prophylaxis (> 72 hours from admission), and the respective incidences in progression of intracranial hemorrhage. We identified 124 patients for this study. ⋯ Three patients with pharmacological VTE prophylaxis developed ICH progression, with one being clinically significant. Our institutional review demonstrated that it seems safe to initiate early pharmacological VTE prophylaxis in blunt head trauma with stable ICH. Nevertheless, further prospective randomized studies are needed to fully elucidate the safety and efficacy in the timing of prophylaxis for blunt head trauma with ICH.

Comparative StudyCan computed tomography scan be performed effectively in the diagnosis of acute appendicitis without the added morbidity of rectal contrast?
The highest degrees of accuracy have been demonstrated for CT scans using rectal contrast in diagnosing appendicitis. However, the administration of rectal contrast is associated with patient discomfort and rarely, rectosigmoid perforation (0.04%). Additionally, the commonly accepted negative appendectomy rate is around 16 per cent. ⋯ Two hundred and forty-five inpatient CT scans were performed for suspected appendicitis with a sensitivity of 90 per cent, specificity of 98 per cent, accuracy of 94 per cent, positive predictive value of 98 per cent, and negative predictive value of 91 per cent. CT scanning without rectal contrast is effective for the diagnosis of acute appendicitis making rectal contrast, with its attendant morbidity, unnecessary. The previously acceptable published negative appendectomy rate is higher than that found in current surgical practice likely due to preoperative CT scanning.

Blunt thoracic aortic injury (BAI) is a rare but often fatal injury that occurs with severe polytrauma. Immediate diagnosis and treatment of BAI are essential for a successful outcome. We reviewed our experience with 20 patients with BAI treated at a Level I trauma center between 1995 and 2006. ⋯ BAI is rare and often associated with multiple life-threatening injuries complicating diagnosis and treatment. Our data support the aggressive use of CTA even when classic CXR findings are not present. When CT must be delayed for abdominal exploration, intraoperative TEE is useful.

Comparative StudyBlood transfusions in trauma: six-year analysis of the transfusion practices at a Level I trauma center.
The objective of this study was to analyze the transfusion practices in trauma patients in one institution. A retrospective analysis of the Trauma Registry linked with the Blood Bank Database of a Level 1 trauma center was conducted. Over 6 years, 17 per cent of the 25,599 trauma patients received blood transfusions. ⋯ The highest reduction in PRBC transfusion was seen in blunt trauma patients (34.6%, P < 0.001). During the study period there was a concurrent increase in mean units of fresh frozen plasma used (60.7%, P < 0.001) and no change in the use of platelets and cryoprecipitate. In conclusion, transfusions of PRBC were significantly reduced over time in trauma patients without any evident negative impact on mortality.

Comparative StudyThe Surgical Care Improvement project (SCIP) initiative to reduce infection in elective colorectal surgery: which performance measures affect outcome?
One component of the Surgical Care Improvement Project (SCIP) is the prevention of surgical site infections (SSIs) by: 1) timing the administration of prophylactic antibiotics (PAs) within 1 hour of incision; 2) using approved PA regimens; and 3) discontinuing PA within 24 hours. We sought to evaluate institutional compliance with SCIP recommendations in patients undergoing elective colorectal surgery and determine whether they affected the incidence of SSI. One hundred four elective colorectal cases were reviewed. ⋯ There was no significant difference in the incidence of SSI in patients who received compliant versus noncompliant PA (12.7% vs 9.1%, P = 0.75). Timely PA administration significantly reduces the incidence of SSI in patients undergoing elective colorectal surgery. Efforts should focus on ensuring that PAs are given in a timely manner to reduce SSI in colorectal surgery.
