Effect of nerve stimulator on combined lumbar plexus-sciatic nerve block in leg surgery

Objective To observe the anesthesic efficacy of nerve stimulator in combined lumbar plexus-sciatic nerve block for leg surgery. Methods A total of 20 patients (male 12,female 8; aged 18 -76 years),were performed leg surgery with American Society of Anesthesiologists(ASA) Ⅰ to Ⅲ. The time of performing anesthesia,occurring of anesthesic effect and duration of post-operative analgesia were observed and recorded. Results Of these patients 18 cases had satisfactory efficacy of the nerve block. But 2 patients were unsatisfied effect. The difference of systolic blood pressure(SBP),diastolic blood pressure(DBP),heart rate(HR) before and after anesthesia and post operation had no statistical significance(P 0.05). There was no complication occurred during operation and postoperation. Conclusion The clinical efficacy of combined lumbar plexus-sciatic nerve block for leg surgery performed under the guidance of a nerve stimulator is satisfactory and fewer complications has found.
