Comparison of Anesthetic Effects of Three Methods of Spinal Canal Administration for Cesarean Section

Objective] To explore the effect of three methods of spinal canal anesthesia for cesarean section on the anesthesia efficacy of parturients. Methods] Sixty parturients undergoing cesarean section were randomly divided into Group A, B and C with 20 cases in each. Group A was given 3mg（15mg） 0.5% hyper- baric bupivacaine. Group 13 was given 2mL（10mg） 0.5%hyperbaric bupivacaine and epidura filling of 10mL 0. 25% bupivacaine. Group C was given 7. 5mg（1. 5mL） 0. 5% hyperbaric bupivacaine and 20ug fentanyl. Mean arterial pressure（MAP）, heart rate（HR）, the degree of motion block and the regression time of the level at basic value（T1）, lmin afler anesthesia（T2 ） , 5min after anesthesia（T3 ） and the end of the operation（T4 ） were detected and recorded. Results] Compared with T1, MAP at T2 after anesthesia in three groups decreased with a certain extent（ P〈0.05）. MAP at T2 and Ta in group A decreased more significantly than that in Group B and C（ P〈0.01）, but there was no significant difference between Group B and C（ P 〉0.05）. The bromage score in Group A was higher than that in Group B and C（ P〈0.05）. The regression time of the level in Group A was longer than that in Group B and C（ P〈0.01）, but there was no obvious differences between Group B and C（ P 〉0.05）. Conclusion] The two methods of the medication such as10mg bupivaeaine combined with epidural filling, 7.5mg bupivacaine combined with 20ug fentanyl have little effect on hemodynamics and good effect on muscle relaxation. They are worthy to be popularized.
