Report of the 2022 Perfusion Perspectives of Waste Anesthetic Gas Exposure Survey.

OBJECTIVES: To describe perfusionist perspectives regarding waste anesthetic gas (WAG) management during cardiopulmonary bypass (CPB) and compare results to existing American Society of Extracorporeal Technology (AmSECT) guidelines and the 2016 National Institute of Occupational Safety and Health Survey of healthcare workers and anesthesia care providers. DESIGN: We developed a questionnaire with 26 questions covering institutional demographics, use of anesthetic gases, scavenging systems, and air monitoring practices. SETTING: Web-based survey. PARTICIPANTS: Self-identified board-eligible perfusionist members of AmSECT, the American Academy of Cardiovascular Perfusion, and the Maryland and Wisconsin State Perfusion Societies in 2022. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of the 4,303 providers sent the survey, 365 (8.5%) participated. Although 92% of the respondents (335/364) routinely administered inhaled anesthetics via the oxygenator, only 73.2% (259/354) routinely scavenged WAG during CPB cases. Only 6.6% of the respondents (22/336) conducted environmental monitoring for WAG levels. Cited reasons for not scavenging waste gases included a lack of applicable protocols and waste gas scavenging systems, excessive cost, and no need for scavenging. CONCLUSIONS: Our findings identify a gap between AmSECT guidelines and current perfusionist behavior and suggest potential strategies for reducing WAG leakage during CPB. Effective management should incorporate hazard awareness training, availability of standard procedures to minimize exposure, scavenging systems, regular equipment inspection, and prompt attention to spills and leaks. In high-risk environments, environmental surveillance for waste gas levels would also contribute to waste gas safety. A comprehensive approach to managing waste anesthetic gases will reduce WAG leakage, help improve health care worker safety, and prevent potential adverse effects of exposure.

A Case Report of Percutaneous Right Ventricular Assist Device Utilization After Cesarean Delivery in a Patient With Severe Pulmonary Arterial Hypertension.

Physiologic changes of pregnancy are poorly tolerated in patients with pulmonary arterial hypertension (PAH), and peripartum maternal mortality is high. We present a case of a 31-year-old G3P0020 patient at 35 weeks' gestation with severe World Health Organization group I PAH who underwent cesarean delivery followed by percutaneous right ventricular assist device placement. Risks and benefits of the mode of delivery, neuraxial versus general anesthesia, and mechanical circulatory support are reviewed.

Management strategies for patients with neurologic stimulators during nonneurologic surgery: an update and review.

PURPOSE OF REVIEW: The goal of this review is to summarize the perioperative management of noncardiac implanted electrical devices (NCIEDs) and update the anesthesiologist on current recommendations for management when a NCIED is encountered during a nonneurosurgical procedure. RECENT FINDINGS: Indications for NCIEDs continue to expand, and increasing numbers of patients with NCIEDs are presenting for nonneurosurgical procedures. Recent case reports demonstrate that NCIEDs may meaningfully affect perioperative management including use of electrocautery and neuromonitoring. This review highlights the importance of evaluating NCIED function (including lead impedance) prior to surgery, provides an update on the MRI compatibility and safety of these devices, and reviews the management of patients with altered respiratory drive because of vagal nerve stimulators. SUMMARY: As the prevalence of NCIEDs in patients presenting for surgery increases, anesthesiologists will likely encounter these devices more frequently. To provide a well tolerated anesthetic, anesthesiologists should recognize the concerns associated with NCIEDs and how best to address them perioperatively.

Determinants of Professional Fulfillment and Burnout Among Intensivists: A National Survey by the Society of Critical Care Anesthesiologists in 2022.

BACKGROUND: Increased burnout and decreased professional fulfillment among intensive care physicians is partly due to intensive care unit (ICU) workload. Although the SARS-CoV-2 (COVID-19) pandemic increased ICU workload, it also may have increased feelings of personal fulfillment due to positive public perceptions of physicians caring for COVID patients. We surveyed critical care anesthesiologists to identify the effect of provider demographics, ICU workload, and COVID-19-related workload, on professional fulfillment and burnout. METHODS: We performed an exploratory survey of 606 members of the Society of Critical Care Anesthesiologists (SOCCA) in January and February 2022. We used the Stanford Professional Fulfillment Index (PFI) to grade levels of professional fulfillment and markers of burnout (ie, work exhaustion and disengagement). Univariable and multivariable models were used to identify associations between provider demographics and practice characteristics and professional fulfillment and work exhaustion. RESULTS: One hundred and seventy-five intensivists (29%) responded. A total of 65% were male and 49% were between 36 and 45 years old. The overall median PFI score-0 (none) to 24 (most professional fulfillment)-was 17 (IQR, 1-24), with a wide distribution of responses. In multivariable analysis, factors associated with higher professional fulfillment included age >45 years ( P =.004), ≤15 weeks full-time ICU coverage in 2020 ( P =.02), role as medical director ( P =.01), and nighttime home call with supervision of in-house ICU fellows ( P =.01). CONCLUSIONS: Professional fulfillment and work exhaustion in this cross-sectional survey were associated with several demographic and practice characteristics but not COVID-19-related workload, suggesting that COVID-19 workload may not have either positive or negative perceptions on professional fulfillment.

Measuring SARS-CoV-2 aerosolization in rooms of hospitalized patients.

Objective: Airborne spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remains a significant risk for healthcare workers. Understanding transmission of SARS-CoV-2 in the hospital could help minimize nosocomial infection. The objective of this pilot study was to measure aerosolization of SARS-CoV-2 in the hospital rooms of COVID-19 patients. Methods: Two air samplers (Inspirotec) were placed 1 and 4 m away from adults with SARS-CoV-2 infection hospitalized at an urban, academic tertiary care center from June to October 2020. Airborne SARS-CoV-2 concentration was measured by quantitative reverse transcription polymerase chain reaction and analyzed by clinical parameters and patient demographics. Results: Thirteen patients with COVID-19 (eight females [61.5%], median age: 57 years old, range 25-82) presented with shortness of breath (100%), cough (38.5%) and fever (15.4%). Respiratory therapy during air sampling varied: mechanical ventilation via endotracheal tube (n = 3), high flow nasal cannula (n = 4), nasal cannula (n = 4), respiratory helmet (n = 1), and room air (n = 1). SARS-CoV-2 RNA was identified in rooms of three out of three intubated patients compared with one out of 10 of the non-intubated patients (p = .014). Airborne SARS-CoV-2 tended to decrease with distance (1 vs. 4 m) in rooms of intubated patients. Conclusions: Hospital rooms of intubated patients had higher levels of aerosolized SARS-CoV-2, consistent with increased aerosolization of virus in patients with severe disease or treatment with positive pressure ventilation through an endotracheal tube. While preliminary, these data have safety implications for health care workers and design of protective measures in the hospital. Level of Evidence: 2.

100 Years of Critical Care in the Pages of Anesthesia & Analgesia.

The founding of Anesthesia & Analgesia (A&A) in 1922 was roughly contemporaneous with the creation of the first intensive care unit (ICU) in the United States at Johns Hopkins in 1923. Throughout the next 100 years, the pages of A&A have mirrored the development of critical care as its own distinct specialty. Although primarily a journal focused on intraoperative anesthesia, A&A has maintained a small but steady presence in critical care research. This review highlights the history and development of critical care publications in the pages of A&A from early observations on the physiology of critical illness (1922-1949) to the groundbreaking work of Peter Safar and others on cardiopulmonary resuscitation (1950-1970), the growth of modern critical care (1970-2010), and the 2020 to 2022 coronavirus disease 2019 (COVID-19) era.

Anesthesiology Residency Recruitment: A Prospective Study Comparing In-Person and Virtual Interviews.

Background: Residency recruitment requires significant resources for both applicants and residency programs. Virtual interviews offer a way to reduce the time and costs required during the residency interview process. This prospective study investigated how virtual interviews affected scoring of anesthesiology residency applicants and whether this effect differed from in-person interview historical controls. Methods: Between November 2020 and January 2021, recruitment members at the University of Chicago scored applicants before their interview based upon written application materials alone (preinterview score). Applicants received a second score after their virtual interview (postinterview score). Recruitment members were queried regarding the most important factor affecting the preinterview score as well as the effect of certain specified applicant interview characteristics on the postinterview score. Previously published historical controls were used for comparison to in-person recruitment the year prior from the same institution. Results: Eight hundred and sixteen virtual interviews involving 272 applicants and 19 faculty members were conducted. The postinterview score was higher than the preinterview score (4.06 versus 3.98, P value of <.0001). The change in scores after virtual interviews did not differ from that after in-person interviews conducted the previous year (P = .378). The effect of each characteristic on score change due to the interview did not differ between in-person and virtual interviews (all P values >.05). The factor identified by faculty as the most important in the preinterview score was academic achievements (64%), and faculty identified the most important interview characteristic to be personality (72%). Conclusions: Virtual interviews led to a significant change in scoring of residency applicants, and the magnitude of this change was similar compared with in-person interviews. Further studies should elaborate on the effect of virtual recruitment on residency programs and applicants.
