摘要
目的:观察不同浓度利多卡因复合罗哌卡因及单用罗哌卡因对坐骨神经阻滞起效时间的影响。方法:90例行单侧下肢手术的病人,随机分A、B、C三组(n=30)。采用神经刺激器定位行单侧坐骨神经-腰丛阻滞。三组坐骨神经用药分别为2%或1%利多卡因与罗哌卡因联合及单纯罗哌卡因。记录三组腓肠神经外侧皮支(SN)、腓浅神经(FN)、胫神经跟内侧支(TN)的起效时间。记录起效时间小于15min及20min的例数及该时间点可以手术病人百分率。结果:A组TN起效时间快于B组与C组(P<0.05),A、B两组SN、FN起效时间快于C组(P<0.05);SN、FN、TN起效时间小于15min及20min的例数在A/B/C三组分别为28/24/14、25/19/12、29/19/16和29/28/23、29/24/19、30/23/23;A、B、C三组可以手术病人百分率在15min和20min时分别为83.3%、43.3%、33.3%和96.7%、66.7%、60%,A组大于B组和C组(P<0.01)。结论:应用2%利多卡因复合罗哌卡因坐骨神经起效时间较快,是较好的临床用药组合。
Objective：To observe the effect of lidocaine with different concentration combined with rupivocaine or rupivocaine alone on the onset time of sciatic nerve. Methods： Ninety patients who were undergone Operation on the lower Limb were randomly divided into group A, group B and group C （n=80）. Sciatic nerve combined lumbar plexus block were performed in all patients. Sciatic nerve was block with 2% lidocaine, 1% lidocaine combined ropivocaine or ropivocaine alone in group A,B and C respectively. The onset time of lateral cutaneous branch of sural nerve（SN）, superficial peroneal nerve（FN）,rami calcanei mediales nervi tibialis（TN） and the number of nerves in which onset time was less than 15 minutues or 20 minutues were recorded. The percentage of patients reedy to undergo surgery in 15 min and 20 min was recorded. Results： The onset time of TN in gronp A was faster than that in gronp B and gronp C （P〈0.05）, the onset time of SN and FN in group Aand group B was faster than that in group C （P〈0.05）, The number of cases whose onset time of SN, FN, TN was less than 15 minrtues or 20 minutues were 28/24/14,25/19/12,29/19/16 and 29/28/23,29/PA/19,30/23/23 in group A, B, C, respectively. The percentage of patiens ready to ondergo surgery in 15 rain and 20 rain was 83.3%,43.3%,33.3% and 96.7%,66.7%,60% in group A,B,C,respectively.The percentage in group A was than that in group B and group C（P〈0.01 ）. Conclusion： The onset time using 2% lidocaine and ropivocaine is faster in sciatic nerve block. Combination of the two local anesthetic is more suitable in clinics.
