ZHOU Riyong,XU Xuzhong.. The effect of ultrasound-guided popliteal sciatic nerve combined saphenous nerve blocks for surgical of diabetic foot[J]. JOURNAL OF WEZHOU MEDICAL UNIVERSITY, 2014, 44(11): 825-.
Abstract：Objective: To observe the anesthesia effect of popliteal sciatic nerve and saphenous nerve block guided with ultrasound for diabetic foot surgery. Methods: Sixty patients undergoing diabetic foot surgery were randomly assigned to nerve block group (group NB) and Epidural block group (group EA) with 30 cases each group. Group NB: popliteal sciatic nerve block and saphenous nerve block on the adductor canal level guided with ultrasound. Group EA: routine lumbar epidural anesthesia 3-4 gap. Two groups of local anesthetics are lidocaine 2% 5 mL+0.75% ropivacaine 10 mL. Following variables were recorded: the anesthesia efficacy, rating as excellent, effective and failure; onset time of nerve block, duration of perioperative; blood pressure and heart rate during perioperative, Numeric rating scale (NRS) 24 h after operationg was used to assess the intensity of pain. Results: Anesthesia efficacy were no signifcant between two groups; the onset time were no signifcant differences between two groups, but the duration of sensory and motor block in group EA were obviously shorter than those of group NB (P<0.05). The SBP and DBP during perioperative has no significant change in Group NB before and after anesthesia. while in Group EB, SBP and DBP were lower at the time 15, 30 min after anesthesia (P<0.05). The changes of intraoperative blood pressure and heart rate were significantly differences between the two groups (P<0.05). Group NB were significantly lower NRS scores than Group EB (P<0.05). Conclusion: Ultrasound-guided popliteal sciatic nerve combined with saphenous nerve block for diabetic foot surgery has the equivalent analgesia and more stable hemodynamics with superior postoperative analgesia compared with epidural anesthesia.
