Obstetric Anesthesia Practice in the Tertiary Care Center: A 7-Year Retrospective Study and the Impact of the COVID-19 Pandemic on Obstetric Anesthesia Practice

There are many benefits of neuraxial anesthesia (NA) in the obstetric population. We performed a retrospective analysis of anesthesia provided to obstetric patients in the tertiary care center between 1 January 2014 and 31 December 2020 and the influence of the COVID-19 pandemic on anesthetic practice. A total of 15,930 anesthesia procedures were performed. A total of 2182 (17.52%) cesarean sections (CS) required general anesthesia (GA), including 383 (3.07%) of emergency conversion from NA. NA for CS consisted of 9971 (80.04%) spinal anesthesia (SA) and 304 (2.44%) epidural anesthesia (EPI). We found a decrease in the GA rate for CS in 2020 (11.87% vs. 14.81%; p < 0.001). The conversion rate from NA to GA for CS was 2.39% for SA and 31.38% for EPI. The conversion rate from labor EPI to SA for CS increased in 2020 (3.10% vs. 1.24%; p < 0.001), as well as the SA rate for other obstetric procedures (61.32%; p < 0.001). We report 2670 NA for vaginal delivery, representing 31.13% of all vaginal deliveries. NA constituted the vast majority of obstetric anesthesia. However, we report a relatively high incidence of GA. There was a decrease in GA use in the obstetric population during the pandemic. Further reduction in GA use is possible, including an avoidable conversion from NA to GA.

Automated summary

There are many benefits of neuraxial anesthesia in the obstetric population. The study found a decrease in the use of general anesthesia during the COVID-19 pandemic in obstetric patients, suggesting the possibility of further reducing its use.
