Background and Aims: Spinal anesthesia is the preferred technique over general anesthesia in caesarean section. General anesthesia is still used for category-1 emergency caesarean section because of time constraints. We usually follow rapid sequence general anesthesia in obstetrics to avoid aspiration. However, this technique poses several problems. An approach of spinal anesthesia termed as rapid sequence spinal anesthesia has been described. The present study was designed to compare the time intervals (time for anesthesia, time to surgical readiness, incision to delivery time, emergence time) and Apgar score between rapid sequence spinal anesthesia and rapid sequence general anesthesia during category-1 caesarean section and to evaluate whether rapid sequence spinal anesthesia is a better option in category-1 caesarean section. Materials and Methods: In this prospective randomized study, 60 patients of American Society of Anesthesiologists physical status (ASA-PS) I posted for category-1 emergency caesarean section were randomly allocated into two equal groups and received either of the two techniques. Demographic data, respective time intervals, and Apgar scores were noted and compared. Results: The time for anesthesia, surgical readiness, and emergence were significantly longer (P < 0.001) in rapid sequence general anesthesia group as compared to rapid sequence spinal anesthesia group (144.80 ± 3.42 vs 131.20 ± 3.40 s, 178.76 ± 4.09 vs 169.93 ± 3.08 s, 512.13 ± 34.33 vs 222.10 ± 12.80 s). No significant difference was found in incision to delivery time and Apgar scores between the two groups. Conclusion: Because anesthesia to delivery time is shorter in rapid sequence spinal anesthesia, this technique may be equivalent to rapid sequence general anesthesia in category-1 emergency caesarean section.
