Objectives: Report on the use of two statewide Medical Operations Coordination Centers (MOCCs) to manage a rapid surge in pediatric acute and critical care patient needs.

Design: Brief report.

Setting: The states of Washington and Oregon during the pediatric respiratory surge in November 2022/December 2022 which overwhelmed existing pediatric acute and critical care hospital capacity.

Purpose: A study was conducted using high-fidelity electronic health record (EHR)-based simulations with incorporated eye tracking to understand the workflow of critical care pharmacists within the EHR, with specific attention to the data elements most frequently viewed.

Methods: Eight critical care pharmacists were given 25 minutes to review 3 simulated intensive care unit (ICU) charts deployed in the simulation instance of the EHR. Using monitor-based eye trackers, time spent reviewing screens, clinical information accessed, and screens used to access specific information were reviewed and quantified to look for trends.

Background: The COVID-19 pandemic resulted in the need for hospitals to plan for a potential "surge" of COVID-19 patients.

Problem: Prior to the onset of the COVID-19 pandemic, our hospital adult acute care capacity ranged 90% to 100%, and a potential hospital surge was projected for Oregon that would exceed existing capacity.

Approach: A multidisciplinary team with stakeholders from nursing leadership, nursing units, nurse-led case management, and physicians from hospital medicine was convened to explore the conversion of an ambulatory surgical center to overflow patient acute care capacity.

This brief report describes the rapid deployment of a real-time electronic tracking board for all hospitals in the state of Oregon. In preparation for the coronavirus disease 2019 surge on hospital resources, and in collaboration across health systems, with health authorities and an industry partner, we combined existing infrastructures to create the first automated tracking board for our entire state, including bed types by health system and geographic area, and with granularity to the individual unit level for each participating hospital. At the time of submission, we have a live snapshot of 87% of beds in the state, including real-time ventilator data across eight health systems.

Background: Acute right ventricular dysfunction is a challenging problem in the immediate postoperative period following orthotopic heart transplantation. There are no prior reports of the use of inhaled iloprost in the setting of acute right ventricular dysfunction and acute pulmonary hypertension. Our hypothesis was that the use of inhaled iloprost in heart transplant recipients would be associated with a reduction in the duration of mechanical ventilation compared to patients being treated with continuous inhaled epoprostenol.

What We Already Know About This Topic: Electromagnetic interference from monopolar electrosurgery may disrupt implantable cardioverter defibrillators.Current management recommendations by the American Society of Anesthesiologists and Heart Rhythm Society are based on expert clinical opinion since there is a paucity of data regarding the risk of electromagnetic interference to implantable cardioverter defibrillators during surgery.

What This Article Tells Us That Is New: With protocolized electrosurgery dispersive electrode positioning in patients with implantable cardioverter defibrillators, the risk of clinically meaningful electromagnetic interference was 7% in above-the-umbilicus noncardiac surgery and 0% in below-the-umbilicus surgery.

Background: Economic, personnel, and procedural challenges often complicate and interfere with efficient and safe perioperative care of patients with cardiovascular implantable electronic devices (CIEDs). In the context of a process improvement initiative, we created and implemented a comprehensive anesthesiologist-run perioperative CIED service to respond to all routine requests for perioperative CIED consultations at a large academic medical center. This study was designed to determine whether this new care model was associated with improved operating room efficiency, reduced institutional cost, and adequate patient safety.

Objective: In this review, we define learning goals and recommend competencies concerning focused basic critical care ultrasound (CCUS) for critical care specialists in training.

Design: The narrative review is, and the recommendations contained herein are, sponsored by the Society of Critical Care Anesthesiologists. Our recommendations are based on a structured literature review by an expert panel of anesthesiology intensivists and cardiologists with formal training in ultrasound.

Purpose Of Review: Therapeutic hypothermia following out-of-hospital cardiac arrest improves neurological recovery. Coupled with neurological benefit, multiple complications including infection have been associated with therapeutic hypothermia following out-of-hospital cardiac arrest. In this review, we will discuss therapeutic hypothermia, and more broadly, temperature management, as a risk for ICU infection.

BACKGROUND: Therapeutic hypothermia (TH) has been established as an effective treatment for preserving neurological function after out of hospital cardiac arrest (CA). Use of TH has been limited in cardiac surgery patients in particular because of concern about adverse effects such as hemorrhage and dysrhythmia. Little published data describe efficacy or safety of TH in cardiac surgical patients who suffer unintentional CA.

Echocardiography is a rapid, noninvasive, comprehensive cardiac assessment option for patients presenting with hemodynamic instability. In patients with septic shock, echocardiography can be used to guide fluid therapy by measuring collapsibility of the inferior vena cava. Sepsis-induced myocardial dysfunction can be diagnosed, and responses to therapy can be monitored with echo.

Soluble epoxide hydrolase (sEH) metabolizes epoxyeicosatrienoic acids (EETs), primarily 14,15-EET. EETs are derived from arachidonic acid via P-450 epoxygenases and are cardioprotective. We tested the hypothesis that sEH deficiency and pharmacological inhibition elicit tolerance to ischemia via EET-mediated STAT3 signaling in vitro and in vivo.

Article Synopsis
  • Soluble epoxide hydrolase (sEH) breaks down protective molecules known as epoxyeicosatrienoic acids (EETs), which help prevent cell death during heart issues like myocardial ischemia.
  • Researchers investigated whether blocking sEH through gene deletion or drug inhibition could lower heart damage after a temporary lack of blood flow in mice.
  • Results showed that treating mice with sEH inhibitors or EET increased their heart protection significantly, suggesting targeting sEH could be a new way to help patients with heart problems.

There is evidence for differences in the response to the treatment of cardiovascular disease in men and women. In addition, there are conflicting results regarding the effectiveness of pharmacologically induced protection or ischemic preconditioning in females. We investigated whether the ability of Met(5)-enkephalin (ME) to reduce cell death after oxygen-glucose deprivation (OGD) is influenced by the presence of 17beta-estradiol (E(2)) in a nitric oxide (NO)- and estrogen receptor-dependent manner.
