简要总结
56 ASA physical status II and III patients, aged 45-75 year, undergoing elective below knee amputation were randomly assigned to receive either sciatic nerve block using a popliteal approach or a sub gluteal approach. Patients in both groups received same amount of LA and additional ultrasound guided femoral nerve block to ensure sensory block of the medial side of the leg. Success of the block was considered when the block is solid and doesn't require shifting to GA
详细描述
56 ASA physical status II and III patients, aged 45-75 year, undergoing elective below knee amputation were randomly assigned to receive either sciatic nerve block using a popliteal approach (group P, n 28) or a sub gluteal approach (group G, n 28). Patients in both groups received same amount of LA (25 ml of bupivacaine 0.5 %) and additional ultrasound guided femoral nerve block by 10 ml of bupivacaine 0.5% to ensure sensory block of the medial side of the leg. Time to complete sensory and motor block, time taken to perform the block, block-related complications, block duration, time for asking for rescue analgesia in the first 24 h were recorded and both patients and surgeons were asked about their level of satisfaction. Success of the block was considered when the block is solid and doesn't require shifting to GA

研究组 & 干预措施
popliteal sciatic nerve block
injecting 25 ml of bupivacaine 0.5 % (Sunnypivacaine, 20 ml vial contains Bupivacaine HCL Monohydrate 105.5 mg eq. to 100 mg Bupivacaine HCL, Sunny Pharmaceutical, Badr city- Cairo- Egypt) once circumferentially around the sciatic nerve at the popliteal fossa using ultrasound device (S-Nerve ultrasound system, Fujifilm Sonosite Inc., Bothell, WA)
干预措施: sciatic nerve block (Procedure)
subgluteal sciatic nerve block
injecting 25 ml of bupivacaine 0.5 % (Sunnypivacaine, 20 ml vial contains Bupivacaine HCL Monohydrate 105.5 mg eq. to 100 mg Bupivacaine HCL, Sunny Pharmaceutical, Badr city- Cairo- Egypt) circumferentially around the sciatic nerve at the subgluteal region using ultrasound device (S-Nerve ultrasound system, Fujifilm Sonosite Inc., Bothell, WA).
干预措施: sciatic nerve block (Procedure)
结局指标
主要结局
to compare between the two techniques as regards the success rate.
时间窗: 24 hours
Success was considered when the block provided solid analgesia with no need to shift to GA
次要结局
- time taken to perform the block(10-20 min)
