摘要
目的:观察单点法与两点法在腰麻—硬膜外麻醉中的疗效与安全性。方法:选择ASAⅠ-Ⅱ级手术患者84例,分为单点法组与两点法组各4 2例,单点法组选L1～2 间隙行硬膜外穿刺成功后,经硬膜外穿刺针置入2 5G腰穿针,穿破蛛网膜,注入0 .5%布比卡因1 2mg而后退出腰穿针再置入硬膜外导管,两点法组选择L1～2 行硬膜外穿刺置管,然后经L2～3进行腰穿,方法同单点法组。结果:两组患者的麻醉起始时间及硬膜外首次用药时间、血压下降幅度等情况,两组均无明显差别(P >0 .0 5)。腰麻及硬膜外阻滞平面上界、单点法比两点法略低,单点法置管较两点法困难为多。结论:选用两点法操作方便,麻醉平面易控制和衔接,成功率高,单点法的腰麻平面的调节不如两点法随意,急诊手术选用单点法可相对节省时间。
Objective: To investigate the effects and safety of single-segment technique (SST) and double-segment technique (DST)in combined spind-epidurd anesthesia(CSA).Methods: 84 patients of ASA-Ⅱ operation were divided SSTgroup and DST group. The SST group were received spind administration with 0.5% bupivacaine 12mg and then put in epidural catheter through L_ 1～2 interval. The DST group were put in epidural catheter through L_ 1～2 interval and then received spinal administration with bupivocaine 12mg through L_ 2～3 interval. Results: There were no significant.differences in beginning time of anesthesia. First epidural administration with Lidocain and fall level of blood pressure among two groups. The higher boundary line of spinal and epidural block plane was lower in SST group than in DST, but put in epidural catheter was more difficult in SST group than in DST. Conclusions: There are more benefits in CSEA with DST than with SST such as operated more conveniently, anesthesia plane controlled and linked up more easily and higher successful rate of operation. CSEA with SST can save time in emergency operation.
