This study compared the incidence of hypotension and nausea-vomiting induced by bupivacaine and lidocaine in parturients undergoing caesarean section under spinal anaesthesia. Methods and Materials: In this clinical trial, 120 parturients undergoing caesarean section were randomly allocated into two groups. 60 patients received subarachnoid lidocaine 5% (75-100 mg) and the other group of patients received bupivacaine 0.5% (12-15 mg). If systolic blood pressure decreased to 80 mm Hg or less than 70% of the pre-anesthesia value, 5mg ephedrine was injected. We evaluated Blood pressure each 3 minutes up to 15 min and every 5 min thereafter till the end of the recovery stay. Findings: There was no statistically significant difference in the incidence of nausea -vomiting between the two groups after spinal anesthesia. On the other hand, there was significant difference in systolic blood pressure 12 minutes after the procedure and also a significant difference was noted in diastolic blood pressure 3, 9, 15, and 40 minutes after performing spinal anesthesia (P < 0.05). The amount of ephedrine used in both groups did not show either any significant difference. Conclusions: Intrathecal bupivacaine may yield more hemodynamic stability than intrathecal }, URL = {http://jap.iums.ac.ir/article-1-19-en.html}, eprint = {http://jap.iums.ac.ir/article-1-19-en.pdf}, journal = {Anesthesiology and Pain}, doi = {}, year = {2013} }
