Clinical Study of Lumbar Plexus-Sciatic Nerve Block Using Peripheral Nerve Stimulator in the Single Lower Extremity Surgery in Elderly Patients
Abstract：Objective:To study sought to observe the efficacy of lumbar plexus-sciatic nerve block using peripheral nerve stimulator in the single lower extremity surgery in elderly patients. Methods:21 patients undergoing the single lower extremity surgery were received lumbar plexus-sciatic nerve block using peripheral nerve stimulator. The local anesthetic drug was 0.375%ropivacaine,and the amount of drug for lumber plexus blockade and sciatic plexus blockade was 30 ml.The hemodynamics,onset time,duration,efficacy,and adverse reactions were recorded.Results:In hemodynamics,the mean artery pressure(MAP)and the hart rate(HR)of T1(ten minutes after anesthesia),T2(thirty minutes after anesthesia) and T3(operation finish) had no significant difference than that of T0(baseline) (P>0.05);the onset time of sensory block was(8.6±1.7)min,and the duration was (418.2±113.7)min;the onset time of motor block was(12.5±3.1)min,and the duration was (178.7±38.8)min.The excellent anesthesia effect was 90.5%and the fine effect was 9.5%,all the people had few complications.Conclusion:The anesthetic strategy of lumbar plexus-sciatic nerve block using peripheral nerve stimulator will lead to precise anesthesia effect,complete blockade,stable hemodynamics and few complications,which were the reasons why it could be applicable to in the single lower extremity surgery in elderly patients.
