Objectives: Early diagnosis and emergent surgical debridement of necrotizing soft tissue infections (NSTIs) remains the cornerstone of care. We aimed to study the effect of early surgery on patients' outcomes and, in particular, on hospital length of stay (LOS) and Intensive Care Unit (ICU) LOS. Materials and Methods: Over a 6-year period (January 2003 through December 2008), we analyzed the records of patients with NSTIs. We divided patients into two groups based on the time of surgery (i.e., the interval from being diagnosed and surgical intervention): Early (<6 h) and late (≥6 h) intervention groups. For these two groups, we compared baseline demographic characteristics, symptoms, and outcomes. For our statistical analysis, we used the Student's t-test and Pearson Chi-square (χ2) test. To evaluate the clinical predictors of early diagnosis of NSTIs, we performed multivariate logistic regression analysis. Results: In the study population (n = 87; 62% males and 38% females), age, gender, wound locations, and comorbidities were comparable in the two groups. Except for higher proportion of crepitus, the clinical presentations showed no significant differences between the two groups. There were significantly shorter hospital LOS and ICU LOS in the early than late intervention group. The overall mortality rate in our study patients with NSTIs was 12.5%, but early intervention group had a mortality of 7.5%, but this did not reach statistical significance. Conclusions: Our findings show that early surgery, within the first 6 h after being diagnosed, improves in-hospital outcomes in patients with NSTIs.

This is a unique question-and-answer book for surgical residents and trainees, concentrating on the growing subspecialty of surgery in critical care and emergency surgery.This book covers all surgical aspects of critical care and acute or emergency surgery, making it an ideal learning and review  text for surgical trainees and those professionals.

Contrast-induced nephropathy (CIN) in trauma patients is uncommon and the incidence is unknown. We studied the incidence of CIN and its outcome. A retrospective chart review of trauma patients 16 years of age and older who were admitted to our Level I trauma center during 2005 was performed. Patients who received the intravenous contrast CT scan and had their serum creatinine (Cr) monitored at admission and at 48 to 72 hours were identified. CIN was defined as a 0.5-mg/dL rise of serum Cr or a 25 per cent increase from the baseline if the baseline Cr was abnormal. We excluded patients transferred from an outside facility, patients without repeated serum Cr measurements, patients who had cardiac arrest or persistent hypotension, and patients who had received N-acetylcysteine (Mucomyst) before their CT scan. We compared CIN and non-CIN groups. During 2005, 543 fit our study criteria, of whom 19 (3.5%) had CIN. CIN (vs non-CIN) had a higher baseline serum Cr (1.48 + 0.23 vs 1.06 + 0.02, P < 0.001), a longer intensive care unit stay (17 vs 5 days, P < 0.001), and a longer hospital stay (19 vs 8 days, P < 0.001); the mortality rate was not different (10 vs 4%, P = 0.2). We found elevated baseline serum Cr (OR, 1.92; 95% CI, 1.13 to 3.27; P = 0.016) to be associated with increased risk for CIN. All but two serum Cr levels peaked within 48 hours; all returned to baseline. One patient with an underlying congenital kidney disease required temporary dialysis. CIN incidence in trauma is low and the clinical course is benign.

The triad of seatbelt-related severe abdominal wall disruption, hollow viscus injury, and distal abdominal aortic injury after a motor vehicle collision is uncommon. We present a small case series involving those three clinical features with the goal of preventing a future missed diagnosis of the distal abdominal aortic injury in particular.
