Cadaveric study identifying clinical sonoanatomy for proximal and distal approaches of ultrasound-guided intercostobrachial nerve block.

Background And Objectives: The intercostobrachial nerve (ICBN) has significant anatomical variation. Localization of the ICBN requires an operator's skill. This cadaveric study aims to describe two simple ultrasound-guided plane blocks of the ICBN when it emerges at the chest wall (proximal approach) and passes through the axillary fossa (distal approach).

Outcomes of physician patients after non-cardiac surgery: a registry analysis.

Objectives: When physicians become patients, they may expect special privileges, extra attention from caregivers, and non-routine treatments. Consequently, physician patients may not be treated per routine-which possibly worsens care rather than improving it. We thus tested the primary hypothesis that in-hospital mortality and major complications after non-cardiac surgery are more common in physician patients than in non-physician patients.

Impact of Methylprednisolone on Postoperative Quality of Recovery and Delirium in the Steroids in Cardiac Surgery Trial: A Randomized, Double-blind, Placebo-controlled Substudy.

Background: Inflammation after cardiopulmonary bypass may contribute to postoperative delirium and cognitive dysfunction. The authors evaluated the effect of high-dose methylprednisolone to suppress inflammation on the incidence of delirium and postoperative quality of recovery after cardiac surgery.

Methods: Five hundred fifty-five adults from three hospitals enrolled in the randomized, double-blind Steroids in Cardiac Surgery trial were randomly allocated to placebo or 250 mg methylprednisolone at induction and 250 mg methylprednisolone before cardiopulmonary bypass.

A Randomized Trial of a Supplemental Alarm for Critically Low Systolic Blood Pressure.

Background: Intraoperative hypotension is associated with complications that might be ameliorated by earlier intervention. We therefore tested the primary hypothesis that a supplemental decision support alert for critically low systolic blood pressure (SBP) decreases the duration of intraoperative hypotension.

Methods: We enrolled adults having surgery and anesthetized by attending anesthesiologists or nurse anesthetists under attending supervision.

Intraoperative core temperature patterns, transfusion requirement, and hospital duration in patients warmed with forced air.

Background: Core temperature patterns in patients warmed with forced air remain poorly characterized. Also unknown is the extent to which transient and mild intraoperative hypothermia contributes to adverse outcomes in broad populations.

Methods: We evaluated esophageal (core) temperatures in 58,814 adults having surgery lasting >60 min who were warmed with forced air.

Myocardial injury after noncardiac surgery: a large, international, prospective cohort study establishing diagnostic criteria, characteristics, predictors, and 30-day outcomes.

Background: Myocardial injury after noncardiac surgery (MINS) was defined as prognostically relevant myocardial injury due to ischemia that occurs during or within 30 days after noncardiac surgery. The study's four objectives were to determine the diagnostic criteria, characteristics, predictors, and 30-day outcomes of MINS.

Methods: In this international, prospective cohort study of 15,065 patients aged 45 yr or older who underwent in-patient noncardiac surgery, troponin T was measured during the first 3 postoperative days.
