Patients are traditionally kept fasting (NPO) from midnight prior to surgery, to prevent aspiration during anesthesia. NPO time is continued postoperatively, out of concern for ileus. Prolonged periods of NPO place the pediatric population at risk for under-nutrition. Published guidelines for preoperative NPO times have been shown to be safe. The aim of this study was to investigate current pre- and postoperative feeding practices of children at a pediatric tertiary care hospital. ⋯ Observed preoperative NPO time exceeded current recommendations in this study.

Observational StudyPostoperative Cognitive Dysfunction and the Change of Regional Cerebral Oxygen Saturation in Elderly Patients Undergoing Spinal Surgery.
In this study, we examined the relationship between postoperative cognitive dysfunction (POCD) and intraoperative regional cerebral oxygen saturation (rSO2) in elderly patients undergoing spinal surgery. ⋯ This study showed that the duration of decline in rSO2 <60% during lumbar spinal surgery was correlated with the development of POCD at the seventh postoperative day in elderly patients.

CommentDexamethasone as adjuvant for femoral nerve block following knee arthroplasty: a randomized, controlled study.
We examined the effect of the addition of dexamethasone to bupivacaine for femoral nerve blocks on the block duration and the quality of post-operative analgesia following total knee replacement surgery. ⋯ The addition of dexamethasone to bupivacaine for femoral nerve block prolonged the duration of analgesia, improved early post-operative pain following total knee arthroplasty.

Oliguria without serum creatinine increase after living donor liver transplantation is associated with adverse post-operative outcomes.
Acute kidney injury (AKI) is a common complication after liver transplantation and is associated with significant morbidity and mortality. Although clinical guidelines recommend defining AKI based on serum creatinine increase and oliguria, the validity and utility of the oliguric component of AKI definition remains largely unexplored. This study examined the incidence and the impact on clinical outcomes of oliguria meeting the urine output criterion of AKI in patients undergoing liver transplantation. The authors hypothesised that oliguria was an independent risk factor for adverse post-operative outcomes. ⋯ Oliguria is common after liver transplantation, and incorporating oliguria into the diagnostic criteria dramatically increases the measured incidence of AKI. Oliguria without serum creatinine increase was significantly associated with adverse post-operative outcomes.

Cardiopulmonary Bypass-Induced Inflammatory Response: Pathophysiology and Treatment.
The objectives of this review are to discuss the pathophysiology of the pro-inflammatory response to the cardiopulmonary bypass circuit, the impact of ischemia reperfusion injury on post-operative organ function, the compensatory anti-inflammatory response and the evidence for immune-modulatory strategies and their impact on outcomes. ⋯ Innovations such as the development of more biocompatible surfaces and miniaturized circuits, as well as the increasing expertise of surgeons, anesthesiologists and perfusionists has transformed cardiac surgery and the use of cardiopulmonary bypass into a relatively routine procedure with favorable outcomes. Despite these refinements, the attendant inflammatory response to bypass, ischemia reperfusion injury and the compensatory anti-inflammatory response contribute to post-operative morbidity and mortality. Additional studies are needed to further delineate the impact of immunomodulatory strategies on outcomes.
