Bupivacaine spinal anesthesia for cesarean section in the appropriate dose in the observation Author: Lu Chun-Li Li Mei Xiang Qin Haijian [Abstract] Objective To observe and compare different doses of bupivacaine spinal anesthesia in cesarean section in the anesthetic effect, of the appropriate dose of local anesthetic Methods 60 patients in our hospital until the middle term, normal vital signs, need to line the lower uterine segment cesarean section in pregnant women, were randomly divided into three groups, A, B, C group, 20 cases each, choose the line L2 ~ 3 subarachnoid space block, each application of 0.75% bupivacaine dose were as follows: A group of 1.5ml (11.25mg), B group 1.4 ml (10.50 mg), C group 1.3 ml (9.75 mg). observed sensory motor block onset time, feeling lost up to T4 and T6 of the number of cases, the anesthetic effect and adverse results three groups of patients the onset time of anesthesia was no significant difference. anesthesia of T4 over the number of cases, A group than in B, C group (P lt;0.05), analgesic effects A, B above C group (P lt;0.05), hypotension, the incidence of nausea and vomiting in group A than B, C group (P lt;0.05). three groups were no postoperative headache occurred Conclusion 0.75% bupivacaine 1.4 ml for cesarean section spinal anesthesia can provide satisfactory results, vital signs normal, low incidence of adverse reactions.
