Poster Title: Reducing Spinal-Induced Hypotension in Cesarean Sections with Ondansetron
Abstract:
The use of spinal anesthesia for cesarean delivery is widespread due to its simplicity and reliability. Though generally considered a safe technique, hypotension is the most common complication that anesthesia providers face when administering spinal anesthetics to parturients. In this population, hypotension is partly attributed to a cardioinhibitory response called the Bezhold-Jarish reflex which, evidence suggests, may be attenuated by non-vasoactive medications such as ondansetron. This project aims to build upon the foundational work of past initiatives and disseminate evidence-based research to improve the timing and administration of ondansetron prior to cesarean delivery to promote both maternal and fetal safety. Through the PICO framework: Do parturients receiving a spinal for cesarean delivery (P) that receive ondansetron before block onset (I) compared to after block onset (C) have reduced incidence of hypotension (O)? a literature search and review informed the development of educational brochures which were distributed to anesthesia providers at a single hospital setting. Prior to the introduction of the brochure, pre-intervention surveys indicated that 73% of anesthesia providers administered ondansetron prior to onset of spinal anesthesia. After educational materials were distributed, post-intervention surveys showed that 100% of providers administered ondansetron prior to spinal administration. The findings suggest that dissemination of knowledge may be an effective strategy in the enhancement of anesthesia care and may contribute to compliance with best practices. These results are, however, limited by the single-center design and small sample size.
