Considerable debate exists regarding the definition, skill set, and training requirements for the new specialty of acute care surgery (ACS). We hypothesized that a patient subset could be identified that requires a level of care beyond general surgical training and justifies creation of this new specialty. ⋯ ACS and EGS patients represent distinct patient cohorts, as reflected by significant differences in critical care needs, likelihood of multiple operations, and need for postdischarge rehabilitation. The skills required to care for ACS patients, including ability to rescue from complications and provide critical care, differ from those required for EGS patients and supports development of ACS training and regionalization of care.

Sepsis is a potentially fatal whole-body inflammation caused by severe infection. Hydrogen gas (H2) is effective for treating sepsis. In this study, we hypothesized that the protective function of H2 in mice with septic lung injury occurred through the activation of heme oxygenase 1 (HO-1) and its upstream regulator nuclear factor-erythroid 2 p45-related factor 2 (Nrf2). ⋯ H2 plays a significant role in regulating the release of the inflammatory cytokine HMGB1 in septic mice, which is partially mediated through the activation of HO-1 as a downstream molecule of Nrf2.

Patient satisfaction is an increasing area of interest due to implications of pay for performance and public reporting of results. Although scores are adjusted for patient factors, little is known about the relationship between hospital structure, postoperative outcomes, and patient satisfaction with the hospital experience. ⋯ High surgical volume more strongly predicted overall patient satisfaction on the HCAHPS survey than postoperative outcomes, whereas volume was less predictive in other HCAHPS domains. Patients may require more specific questioning to identify high quality, safe hospitals.

Previous studies have demonstrated that ultrasonographic measurement of the inferior vena cava diameter is a useful tool for the evaluation of intravascular volume status in preoperative patients. However, ultrasonographic measurement of inferior vena cava diameter could be limited by factors including obesity, bowel gas, or complex abdominal wounds. Our study sought to determine whether subclavian vein (SCV) diameter measured by ultrasound correlate with central venous pressure (CVP), as another indicator of intravascular volume status in patients undergoing gastrointestinal surgery. ⋯ SCV diameter is consistently low in patients undergoing gastrointestinal surgery as compared with healthy subjects. Measuring the SCV diameter maybe an important addition to the ultrasonographic evaluation of hypovolemia and other potentially volume-depleted patients.

Comparative Study
Early versus late hospital readmission after pancreaticoduodenectomy.
Most studies focus on readmission within 30 d of surgery and may therefore underestimate the true burden of readmission after complex procedures. We therefore sought to explore factors associated with readmission within 90 d of discharge after pancreaticoduodenectomy (PD). ⋯ Readmission within 30 d after PD was associated with patient- and procedure-related factors. Readmission in the 31-90-d window was not associated with patient- or procedure-related factors and may be influenced by the underlying pathology or subsequent medical management for that disease.
