Comparison of 0.5% hyperbaric bupivacaine at different doses after failed spinal anesthesia in cesarean section
Pawan Aggarwal, Shalini Aggarwal

Background: There are drawbacks of spinal anesthesia such as occasional failure (2–4%) to achieve an adequate sensory block. The present study was conducted to compare 0.5% hyperbaric bupivacaine at different doses repeated intrathecally after failed spinal anesthesia in cesarean section. Materials & Methods: This present study was conducted on 68 females of American Society of Anesthesiologists (ASA) I-II, aged between 18 and 40 years, were posted for elective cesarean section in which first spinal anesthesia was failed. Patients were divided into 2 groups of 34 each. Group I patients received 2.4 ml, and Group II patients received 2 ml of 0.5% hyperbaric bupivacaine respectively. Results: The mean operation in group I was 32.4 minutes, in group II was 33.5 minutes, repeat spinal at L3- L4 interface in group I was seen in 7 and in group II was seen in 6, repeat spinal at L4- L5 interface was seen in 25 in group I and 28 in group II and high spinal anesthesia in 2 in group I and 0 in group II was seen. The difference was non- significant (P> 0.05). Atropine requirement in group I was 0.13 mg and in group II was 0.02 mg. Phenylephrine requirement was 205.4 mcg in group I and 105.7 mcg in group II. The difference was significant (P< 0.05). Conclusion: Authors found that spinal anesthesia can be safely repeated in the cesarean section with 2.4 ml of 0.5% hyperbaric bupivacaine provided after first spinal anesthesia. Key words: Bupivacaine, Cesarean, Spinal anesthesia
