Abstract：Objective:To investigate the effectiveness and the influence to hemodynamic of heavy proportion and equal proportion bupivacaine in combined spinal-epidural anesthesia for caesarean section operation.Method:60 cesarean section operation patients with ASAⅠ-Ⅱwere randomly divided into heavy proportion group and equal proportion group with 30 cases each.2 ml 0.5%heavy proportion bupivacaine and equal proportion bupivacaine were injected to two groups at a speed of 0.2 ml/s.The onset time,peak time,sensory block level and the quality of analgesia were assessed.The changes of blood pressure,side effects,the Apgar score of newborn and other indexes were recorded.Result:The anesthetic effect of all cases was satisfactory.There were no significant difference in anesthetic effect,oxyhemoglobin saturation and Apgar score of newborn in two groups.Equal proportion group presented a longer peak time than heavy proportion group(P<0.05),but equal proportion had less effect on the blood pressure.Meanwhile,the movement recovery time of equal proportion was shorter.The side effect incidence rates in equal proportion group were lower than in heavy proportion group(P<0.05).Conclusion:Equal proportion bupivacaine is better in combined spinal-epidural anesthesia for caesarean section operation.
