Hemodynamic changes in patients with SARS-CoV-2 infection presenting for cesarean delivery under spinal anesthesia: a retrospective case-control study.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is associated with adverse maternal and neonatal outcomes. Early studies suggested that COVID-19 was associated with a higher incidence of hypotension following neuraxial anesthesia in parturients. We explored the hemodynamic response to spinal anesthesia for cesarean delivery in pregnant severe respiratory distress syndrome-coronavirus-2 (SARS-CoV-2) positive patients, using a retrospective case-control design. METHODS: We searched our electronic medical records for patients who received spinal anesthesia for cesarean delivery, and were SARS-CoV-2 positive or recovered at delivery, and used historical and SARS-CoV-2 negative controls from two tertiary care hospitals. We compared the demographic, clinical, and hemodynamic variables between patients who were SARS-CoV-2 positive at delivery, those who were positive during pregnancy and recovered before delivery, and controls. Analyses were stratified by normotensive versus hypertensive status of the patients at delivery. RESULTS: We identified 22 SARS-CoV-2 positive, 73 SARS-CoV-2 recovered, and 1517 controls. The SARS-CoV-2 positive, and recovered pregnant patients, had on average 5.6 and 2.2 mmHg, respectively, higher post-spinal mean arterial pressures (MAPs) than control patients, adjusting for covariates. Additionally, the lowest post-spinal MAP was negatively correlated with the number of daysbetween the onset of COVID-19 symptoms and delivery in patients with hypertension (correlation -0.55, 95% CI -0.81 to -0.09). CONCLUSIONS: Patients with SARS-CoV-2 infection during pregnancy exhibit less spinal hypotension than non-infected patients. While the clinical significance of this finding is unknown, it points to important cardiovascular effects of the virus.

Emergency medicine resident involvement in emergency medical services

Introduction: Emergency medical services (EMS) are a critical component to Emergency Medicine (EM) residency training. In the United States, the Accreditation Council for Graduate Medical Education (ACGME) has established minimum training requirements for EM residency programs. Since the last study exploring resident EMS involvement was performed, there have been over 100 new EM resident programs started. Given the rapid increase in new EM programs, we sought to determine EMS experiences provided to current EM residents. Materials and Methods: A 22-question anonymous online survey was distributed through E-mail to program directors of approved EM residencies in October 2020. A follow-up reminder was sent 3 weeks later. Results: In total, 51 of 257 programs responded (20% response rate). Forty-five percent of EM residents experience between 10 and 25 EMS calls during their residency, 31% experience 26-50, and 20% experience >50 calls. The majority of programs (53%) have a separate EMS rotation where residents function as observers, 24% of residents function as providers, and 25% also have residents respond in a dedicated physician response vehicle. Aeromedical exposure is limited (47% have none and 43% average only 1-9 flights). Two-thirds of programs (67%) have residents provide online medical command during their ED shifts and 61% require residents to provide didactics to EMS clinicians. Despite ACGME requirements, only two-thirds of programs (69%) provide training about disaster/mass casualty incident (MCI) management and 67% have them participate in a disaster/MCI drill. About one-third of programs (31%) have decreased EMS experiences due to limited time in the residency curriculum, and 20% of programs have limited EMS experiences due to the COVID pandemic. Conclusions: The majority of responding EM residency programs meet ACGME EMS-related requirements. There is an opportunity for improvement around disaster education based on these data. Limited time in the curriculum and the COVID pandemic were cited as reasons that programs have limited their EMS experiences.
