Methods Forty primiparas with a full term fetus were divided randomly into group A(n=20) and B(n=20). They were accepted a 13 ml of 3% chloroprocaine or 10.8 ml of 2.5% chloroprocaine at lumbar 2~3 epidural space in the group A or Group B ,respectively . Results (1)Onset time (1.75±0.55min vs 1.76±0.37min),pain free time of incision(9.30±1.53min vs 8.71±1.54min ) and pain appearance time of incision (9.30±1.53min vs 8.71±1.54min )were similar in both groups, respective. (2)Effects of anesthesia and analgesia were satisfactory in both groups, none of cases needed any analgesics for pain.(3)Ranges of nerve block(thoracic 5.05±1.19~sacral 3.40±1.25 vs thoracic 5.10±0.94~sacral 3.95±1.10)were similar in both groups.(4)Motor blockade depths of the lower limbs in group B were significantly bigger(p<0.01) than those in group A. (5)Changes of blood pressure and heart rate were not restrained .Conclusion 2.5% and 3% chloroprocaine all can produce satisfying epidural anesthesia for cesarean section , the 2.5% chloroprocaine has a lesser lower limbs motor blockade. |
国产盐酸氯普鲁卡因(可谱诺)已用于临床麻醉3年,我们曾对其用于硬膜外麻醉、臂丛神经阻滞及局部侵润麻醉做过临床观察[1,2,3]。本文专选择剖宫产,再次观察其麻醉效果,并用不同浓度进行比较。 |
结 果 3. 运动阻滞程度及神经阻滞范围:B组运动阻滞程度明显比A组强(p<0.01)。B组以III级阻滞为主占65%。A组则以I级阻滞为主占60%。神经阻滞范围两组相一致。见表2。 4. 两组血压、心率的变化:麻醉后均有一定程度的血压下降,平均最大下降均未超过10%,血压相对稳定。心率在麻醉后也有加快,但平均增加亦未超过10%。见表3。 5. Apgar评分:婴儿娩出后1分钟A、B两组 Apgar 评分分别为8.89±1.06和8.90±1.04,5分钟后分别为9.95±0.22和9.89±0.32。无一例低于7分。 |
