Abstract:
Objective To investigate the influence of Bupivacaine injection speed on blood pressure of patients undergoing cesarean section.Methods 90 patients(ASAⅠ-Ⅱ)who underwent cesarean section were selected with combined spinal-epidural anesthesia were divided randomly into three groups(20 for each).0.5% bupivacaine 1.4ml(7mg),the speed of injection in group A,group B and group C is 10 seconds,20 seconds,30 seconds.Systolic blood pressure(SBP),Diastolic blood pressure(DBP)and Heart rate(HR)were recorded before anesthesia and 5min,10min,15min and 30min after anesthesia.Cases need to be added epidural drug were all recorded.Results The age,body length and body weight in the three groups has no significant difference,location of injection and posture were same.The best effect of anesthesia was founded in group B,blood pressure(BP)and HR was stable.The effect of anesthesia was better but BP and HR were obviously descent in group A.The block level of anesthesia was unsatisfactory and need to add epidural drug in group C.Conclusion The injection speed of 0.5% bupivacaine 1.4ml in combined spinal-epidural anesthesia is suitable of 20 seconds when patients underwent cesarean section.
