With estimated global post-operative mortality rates at 1-4% leading to approximately 3-12 million deaths per year, an urgent need exists for reliable measures of perioperative risk. Existing approaches suffer from poor performance, place a high burden on clinicians to gather data, or do not incorporate intraoperative data. Prior work demonstrated that intraoperative anesthetics induce prefrontal EEG oscillations in the alpha band (8-12Hz) that correlate with post-operative cognitive outcomes. ⋯ Intraoperative EEG alpha power is independently associated with post-operative mortality and adverse outcomes, suggesting it could represent a broad measure of post-operative physical resilience and provide clinicians with a low-burden, personalized measure of post-operative risk.

Handoff Mnemonics Used in Perioperative Handoff Intervention Studies: A Systematic Review.
Perioperative handoffs are known to present unique challenges to safe and effective patient care. Numerous national accrediting bodies have called for standardized, structured handoff processes. Handoff mnemonics provide a memory aid and standardized structure, as well as promote a shared mental model. We set out to identify perioperative handoff intervention studies that included a handoff mnemonic; critically assess process and patient outcome improvements that support specific mnemonics; and propose future recommendations. ⋯ While the evidence supporting one handoff mnemonic over others is weak, SBAR/SBAR variants have been studied more often in the perioperative environment demonstrating some process improvements. A key finding is that 70% of included studies converted their handoff mnemonic to a list or checklist. Finally, given the essential nature of effective handoffs to perioperative patient safety, it is crucial that handoff interventions are well developed, implemented, and evaluated. We propose 8 recommendations for future perioperative handoff mnemonic clinical interventions and research.

Renal resistive index assessment by intraoperative transesophageal echocardiography is associated with acute kidney injury after cardiac surgery: a prospective observational study.
Acute kidney injury (AKI) is a major health burden after cardiac surgery. Renal vasoconstriction and venous congestion can be assessed via transesophageal echocardiography (TEE). The primary objective is to determine feasibility of measuring intraoperative Renal resistive index (RRI) and portal vein pulsatility fraction (PF) by TEE. The secondary objectives are to determine the association between RRI and/or PF and postoperative AKI, Intensive Care Unit (ICU) length of stay, hospital length of stay, and 30-day mortality. ⋯ This study demonstrates high feasibility for obtaining intraoperative TEE measurement of RRI and PF and significant correlation between postoperative AKI with pre CPB RRI, post chest closure RRI, and the combination of RRI at the three timepoints.

Extracorporeal cardiopulmonary resuscitation (ECPR) for refractory in-hospital cardiac arrest has been associated with improved survival compared with conventional cardiopulmonary resuscitation (CPR). Perioperative patients represent a unique of the inpatient population. This study aims to describe and analyze the characteristics and outcomes of patients who received ECPR for perioperative cardiac arrest (POCA). ⋯ The use of ECPR for adults with POCA can be associated with excellent survival with neurologically favorable outcomes in carefully selected patients. Longer CPR time, higher lactate levels, and lower pH were associated with increased mortality. Given the small sample size, no other prognostic factors were identified, though certain trends were detected between survival groups.
