Post-Operative Cognitive Dysfunction in Elderly Patients Receiving Propofol Sedation for Gastrointestinal Endoscopies: An Observational Study Utilizing Processed Electroencephalography.

Background: Propofol sedation is commonly administered during gastrointestinal (GI) procedures. The Patient State Index (PSI) is a processed electroencephalography (EEG) parameter obtained with the SedLine Sedation Monitoring system (Masimo Corporation, Irvine, CA). When used to objectively assess the patient's level of consciousness, PSI may provide a more effective, safer titration of sedation during GI procedures.

Extracorporeal Membrane Oxygenation for COVID-19: Comparison of Outcomes to Non-COVID-19-Related Viral Acute Respiratory Distress Syndrome From the Extracorporeal Life Support Organization Registry.

Unlabelled: To compare complications and mortality between patients that required extracorporeal membrane oxygenation (ECMO) support for acute respiratory distress syndrome (ARDS) due to COVID-19 and non-COVID-19 viral pathogens.

Design: Retrospective observational cohort study.

Setting: Adult patients in the Extracorporeal Life Support Organization registry.

Complications of Transesophageal Echocardiography: A Review of Injuries, Risk Factors, and Management.

Transesophageal echocardiography (TEE) use has become widespread in cardiac surgical operating rooms over the last 2 decades. Surgical and medical decision-making often are guided by the findings of the TEE examination, rendering TEE an invaluable tool both inside and outside the operating room. TEE has become ubiquitous in some parts because it is considered safe and relatively noninvasive.

The Incidence, Degree, and Timing of Hypocalcemia From Massive Transfusion: A Retrospective Review.

Background: Electrolyte administration during massive transfusion without readily available calcium laboratory values is likely ubiquitous but not well standardized. We aimed to quantify the incidence, degree, and timing of hypocalcemia during the first 24 hours after initiation of a massive transfusion with the institutional massive transfusion protocol (MTP). We hypothesized that hypocalcemia is prevalent during acute resuscitation (first six hours) despite efforts of the treatment team to replete calcium during active resuscitation.
