The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) empowers surgeons and medical centers to reliably collect, analyze, and act on clinically collected outcomes data. How individual ACS NSQIP leaders designated as Surgeon Champions (SC) utilize the ACS NSQIP at the hospital level and the obstacles they encounter are not well studied. ⋯ Active use of ACS NSQIP data provide SC with demonstrable CQI by regularly reviewing data, having frequent interaction with clinical reviewers, and frequently sharing data with hospital administration and colleagues. SC thus play a key role in successful quality improvement at the hospital level.

Although many sepsis treatments have shown efficacy in acute animal models, at present only activated protein C is effective in humans. The likely reason for this discrepancy is that most of the animal models used for preclinical testing do not accurately replicate the complex pathogenesis of human sepsis. Our objective in this study was to develop a clinically applicable model of severe sepsis and gut ischemia/reperfusion (I/R) that would cause multiple organ injury over a period of 48 h. ⋯ This animal model of Sepsis+I/R replicates the systemic inflammation and dysfunction of the major organ systems that is typically seen in human sepsis and trauma patients. The model should be useful in deciphering the complex pathophysiology of septic shock as it transitions to end-organ injury thus allowing sophisticated preclinical studies on potential treatments.

Comparative Study
Comparison of "open lung" modes with low tidal volumes in a porcine lung injury model.
Ventilator strategies that maintain an "open lung" have shown promise in treating hypoxemic patients. We compared three "open lung" strategies with standard of care low tidal volume ventilation and hypothesized that each would diminish physiologic and histopathologic evidence of ventilator induced lung injury (VILI). ⋯ None of the "open lung" techniques were definitively superior to LowVt with respect to VILI; however, APRV oxygenated and ventilated more effectively and reduced cytokine concentration compared with LowVt with nearly indistinguishable histopathology. These data suggest that APRV may be of potential benefit to critically ill patients but other "open lung" strategies may exacerbate injury.

Anastomotic leakage following colorectal surgery still occurs all too frequently, and this complication is difficult to predict. A nonfunctional stoma may reduce the risk of clinically relevant leaks but is overtreatment for most patients. More accurate assessments of the risk of anastomotic leakage would be very helpful in tailoring treatment in colorectal surgery. Therefore, a Colon Leakage Score (CLS) was developed and tested. ⋯ The CLS can predict the risk of anastomotic leakage following left-sided colorectal surgery. After further validation, this score may help the surgeon make a more individualized, safer decision regarding whether to perform an anastomosis or make a (nonfunctional) stoma.

Randomized Controlled Trial
Tramadol use for axillary brachial plexus blockade.
We investigated the effects of tramadol added to the mixture of local anesthetic for axillary brachial plexus blockade (ABB) in patients to have undergone hand and forearm surgery. ⋯ Adding 100 mg of tramadol to the combination of levobupivacaine and lidocaine during ABB could not provide an important clinical effect in patients undergoing hand and forearm surgery.
