Association of Neuraxial Anesthesia With Postoperative Venous Thromboembolism After Noncardiac Surgery: A Propensity-Matched Analysis of ACS-NSQIP Database.
Neuraxial anesthesia improves components of the Virchow's triad (hypercoagulability, venous stasis, and endothelial injury) which are key pathogenic contributors to venous thrombosis in surgical patients. However, whether neuraxial anesthesia reduces the incidence of venous thromboembolism (VTE) remain unclear. We therefore tested the primary hypothesis that neuraxial anesthesia reduces the incidence of 30-day VTE in adults recovering from orthopedic surgery. Secondarily, we tested the hypotheses that neuraxial anesthesia reduces 30-day readmission, 30-day mortality, and the duration of postoperative hospitalization. ⋯ Neuraxial anesthesia appears to provide only weak VTE prophylaxis, but can be offered as an adjuvant to current thromboprophylaxis in high-risk patients.

Does the Incidence of Postoperative Complications After Inguinal Hernia Repair Justify Hospital Admission in Prematurely and Term Born Infants?
Postoperatively, young infants are admitted overnight in view of the risk for respiratory complications such as desaturation and apnea. This risk seems much lower than previously reported. Until what age this risk persists, and which infants might actually qualify for day-care treatment, is unknown. ⋯ Incidence of postoperative respiratory complications is high in preterm infants <45 weeks PCA requiring postoperative overnight saturation and heart rate monitoring. Incidence of postoperative complications in preterm born infants 45-60 weeks PCA varies. Gestational age and possibly presence of respiratory history can be used to estimate the need for overnight admission in these infants. Postoperative respiratory complications after inguinal hernia repair in ASA physical status I and II term born infants >1 month of age are uncommon, which justifies day-care admission for this type of surgical procedure.

Extracorporeal Membrane Oxygenation Appropriateness: An Interdisciplinary Consensus-Based Approach.
We describe a quality improvement initiative aimed at achieving interdisciplinary consensus about the appropriate delivery of extracorporeal membrane oxygenation (ECMO). Interdisciplinary rounds were implemented for all patients on ECMO and addressed whether care was consistent with a patient's minimally acceptable outcome, maximally acceptable burden, and relative likelihood of achieving either. The rounding process was associated with decreased days on venoarterial ECMO, from a median of 6 days in 2014 (first quartile [Q1]-third quartile [Q3], 3-10) to 5 days in 2015 (Q1-Q3, 2.5-8) and in 2016 (Q1-Q3, 1-8). Our statistical methods do not allow us to conclude that this change was due to our intervention, and it is possible that the observed decreases would have occurred whether or not the rounding process was implemented.

Anesthetics are widely used drugs administered in a multitude of clinical settings. Their impacts on various functions of the immune system have been studied but are still not fully understood. Neutrophil granulocytes are a critical first-line host defense mechanism against infections and contribute to the inflammatory phase of wound healing, but dysregulated neutrophil activation can also precipitate perioperative organ injury. A better understanding of the interactions between common anesthetics and neutrophils may reveal considerations toward optimizing treatment of our most vulnerable patients in the intensive care unit and in the perioperative setting.
