Sepsis and postoperative surgical site infections.

Surgical site infections remain a significant cause of morbidity and mortality. High-quality evidence supports several measures to prevent surgical site infections that should be applied with high compliance, although effective application remains suboptimal. Recognizing high-risk patients and avoiding potential pitfalls in the diagnosis of surgical site infections is paramount in preventing progression to sepsis, particularly in emergency surgical patients with physiologic derangement. A high index of suspicion postoperatively is critical to identify patients with surgical site infections and to prevent failure to rescue.

Low-volume resuscitation for severe intraoperative hemorrhage: a step in the right direction.

The impact on outcomes resulting from crystalloids used with hemostatic close ratio resuscitation (HCRR) in intraoperative hemorrhage (IOH) has not been analyzed. We hypothesize a survival advantage in patients with IOH managed with a low-volume resuscitation (LVR) protocol during HCRR. A 4-year case-control study was conducted to determine the impact on mortality of LVR versus conventional resuscitation efforts (CRE) during HCRR. A total of 45 patients managed with a HCRR + LVR protocol (combination Hextend® and 3% hypertonic saline) and 55 historical cohorts managed with HCRR + CRE (lactated Ringer's) were included. Patient demographics, number of intraoperative units of packed red blood cells (PRBCs) and fresh-frozen plasma (FFP) received, and FFP:PRBC ratio were similar between groups. The mean intraoperative fluid volume was 0.76 L in the HCRR + LVR group versus 4.7 L in the HCRR + CRE group (P = 0.003). In a linear regression model HCRR + LVR versus HCRR + CRE, mean trauma intensive care unit length of stay was 6 versus 11 days (P = 0.009); 30-day overall mortality was 11.1 versus 32.7 per cent (P = 0.009); perioperative mortality was 2.2 to 10.9 per cent (P = 0.13); and intensive care unit mortality 8.8 to 21.8 per cent (P = 0.07). LVR protocol conveyed a survival benefit to patients undergoing HCRR (odds ratio for mortality, 0.07 [95% confidence interval 0.07-0.54]). This is the first civilian study to analyze the impact of LVR in patients managed with HCRR during IOH. Patients with IOH managed with HCRR and a predefined LVR protocol with Hextend® and 3 per cent hypertonic saline had an overall survival advantage and shorter trauma intensive care unit length of stay. LVR can be an effective alternative to CRE when used in combination with HCRR in patients with IOH.
