Evaluating a Novel EEG-Based Index for Stroke Detection Under Anesthesia During Mechanical Thrombectomy.

Background: The rapid identification of acute stroke (AS) during and after anesthesia might lead to early interventions and improved outcomes. We investigated a novel 2-channel electroencephalogram (EEG)-based marker for stroke detection-the lateral interconnection ratio (LIR)-in AS patients having endovascular thrombectomy (EVT) with general anesthesia (GA) or sedation. The LIR in 2 reference groups of patients without postoperative neurological complications was used for comparison.

The use of bilateral transversus abdominis plane blocks with liposomal bupivacaine on postoperative cesarean delivery patients during COVID-19 pandemic is associated with reduced narcotics use and reduced length of stay.

Background: The use of transversus abdominis plane blocks has been previously shown in both large-scale studies and our own institution to significantly reduce postoperative pain and opioid use. In addition, the use of bilateral transversus abdominis plane blocks using liposomal bupivacaine in combination with neuraxial morphine significantly reduced post-cesarean-delivery pain and opioid use. During the COVID-19 crisis, our anesthesia department in a collaborative effort with our obstetric colleagues thought that the use of bilateral transversus abdominis plane blocks with liposomal bupivacaine could reduce the use of opioids to treat postoperative pain and might result in decreased length of stay.

Perioperative Transfusion Associated With Increased Morbidity and Mortality in Geriatric Patients Undergoing Hip Fracture Surgery.

Introduction: Both conservative and liberal transfusion thresholds, in regard to hematocrit and hemoglobin levels, have been widely studied with varying outcomes. The aim of this study was to evaluate if transfusion administered peri- (anytime during the admission), pre-, intra-, or postoperatively an its association with morbidity and mortality in the geriatric population undergoing hip surgery.

Methods: This study was an institutional review board approved retrospective analysis of data collected from 841 patients at a single urban institution who underwent surgical repairs for hip fractures from 2008 to 2010.

Assessment of Didactic Transesophageal Echocardiography Education During Anesthesia Residency.

Background: Transesophageal echocardiography can be a useful monitor during noncardiac surgery, in patients with comorbidities and/or undergoing procedures associated with substantial hemodynamic changes. The goal of this study was to investigate if transesophageal-echocardiography-related knowledge could be acquired during anesthesia residency.

Methods: After institutional review board approval, a prospective observational study was performed in two anesthesiology residency programs.

Persistent acidosis after reperfusion-A prognostic indicator of increased 30-day and in-hospital postoperative mortality in liver transplant recipients.

During liver transplantation, the patient is at risk of developing progressive lactic acidosis. Following reperfusion, correction of acidosis may occur. In some patients, acidosis will worsen, a phenomenon referred to as persistent acidosis after reperfusion (PAAR).
