Neuraxial Anesthesia during the COVID-19 Pandemic: Report from a Large Academic Medical Center.

OBJECTIVE: Three primary neuraxial techniques reduce labor pain: epidural, dural puncture epidural (DPE), and combined spinal-epidural (CSE). This study aims to determine whether neuraxial analgesia techniques changed after the onset of the coronavirus disease 2019 (COVID-19) pandemic. Given that a dural puncture confirms neuraxial placement, we hypothesized that DPE was more frequent in women with concerns for COVID-19. STUDY DESIGN: A single-center retrospective cohort study comparing neuraxial analgesia techniques for labor and delivery pain management before and after the onset of the COVID-19 pandemic and in patients with and without SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) at a maternity hospital in Dallas, Texas, with a large delivery service. Statistical analyses included the Chi-square test for categorical and Kruskal-Wallis test for nonparametric ordinal comparisons. The Cochran-Mantel-Haenszel test was used to assess the association between neuraxial technique and accidental dural puncture or postdural puncture headache. RESULTS: Of 10,971 patients who received neuraxial analgesia for labor, 5,528 were delivered in 2019 and 5,443 in 2020. Epidural analgesia was the most common neuraxial technique for labor pain in 2019 and 2020. There was no difference in the frequency of neuraxial analgesia techniques or the rates of accidental dural puncture or postdural puncture headaches comparing all deliveries in 2019 to 2020. Despite a significant increase in DPEs relative to epidurals in the SARS-CoV-2-positive group compared with the SARS-CoV-2-negative group in 2020, there was no significant difference in postdural puncture headaches or accidental dural punctures. CONCLUSION: The advantages of a DPE, specifically the ability to confirm epidural placement using a small gauge spinal needle, likely led to an increase in the placement of this neuraxial in SARS-CoV-2-positive patients. There was no effect on the frequency of postdural puncture headaches or accidental dural punctures within the same period. KEY POINTS: · Epidural analgesia was the most common neuraxial technique for labor pain management.. · Dural puncture epidural placements increased in SARS-CoV-2-positive patients.. · Rates of postdural puncture headaches and accidental dural puncture after neuraxial placement did not change..

Examining the impact of trimester of diagnosis on COVID-19 disease progression in pregnancy.

BACKGROUND: COVID-19 infection is associated with increased morbidity in pregnancy and adverse maternal and neonatal outcomes. Little is currently known about how the timing of infection during pregnancy affects these outcomes. OBJECTIVE: This study aimed to evaluate the effect of trimester of COVID-19 infection on disease progression and severity in pregnant patients. STUDY DESIGN: This was a prospective cohort study of pregnant patients diagnosed with COVID-19 infection who delivered at a single urban hospital. Universal testing for SARS-CoV-2 was performed at hospital admission and for symptomatic patients in inpatient, emergency department, and outpatient settings. Disease severity was defined as asymptomatic, mild, moderate, severe, or critical on the basis of National Institutes of Health criteria. We evaluated disease progression from asymptomatic to symptomatic infection and from asymptomatic or mild infection to moderate, severe, or critical illness, and stratified by trimester of COVID-19 diagnosis. Primary outcomes included progression of COVID-19 disease severity and a composite obstetrical outcome, which included delivery at <37 weeks, preeclampsia with severe features, abruption, excess blood loss at delivery (>500 mL for vaginal or >1000 mL for cesarean delivery), and stillbirth. RESULTS: From March 18, 2020 to September 30, 2021, 1326 pregnant patients were diagnosed with COVID-19 and delivered at our institution, including 103 (8%) first-, 355 (27%) second-, and 868 (65%) third-trimester patients. First-trimester patients were older and had more medical comorbidities; 86% of patients in all trimesters were Hispanic. Among patients admitted within 14 days of a positive test, 3 of 18 (17%) first-trimester, 20 of 47 (43%) second-trimester, and 34 of 574 (6%) third-trimester patients were admitted for the indication of COVID-19 illness. Across all trimesters, 1195 (90%) of 1326 COVID-19 infections were asymptomatic or mild, and 45 (10%) of 436 initially asymptomatic patients developed symptoms. Of patients with asymptomatic or mild symptoms at diagnosis, 4 (4%) of 93 first-, 18 (5%) of 337 second-, and 49 (6%) of 836 third-trimester patients developed moderate, severe, or critical illness (P=.80). There was no significant difference in composite obstetrical outcome with respect to trimester of COVID-19 diagnosis (24% first-trimester, 28% second-trimester, 28% third-trimester patients; P=.69). CONCLUSION: Moderate, severe, or critical illness develops in almost 10% of pregnant patients. The frequency of COVID-19 disease progression in pregnancy does not differ by trimester of diagnosis.
