【摘要】 目的比较超声引导下髂筋膜间隙多点阻滞与单点阻滞的效果。方法选择髋关节置换患者125例,ASAⅠ或Ⅱ级,男67例,女58例。进行前瞻随机分为研究组(n=62例)和对照组(n=63例)。研究组采用超声引导下多点阻滞方法,对照组髂筋膜间隙阻滞采用超声引导下单次阻滞方法,局麻药为罗哌卡因150mg复合地塞米松7.5mg,容量为30ml。记录股神经、闭孔神经和股外侧皮神经感觉阻滞的起效时间,并评价其阻滞成功率。结果研究组股外侧皮神经、闭孔神经感觉阻滞起效时间分别为(9.1±3.6)min、(9.2±3.6)min,明显短于对照组的(11.2±4.7)min、(13.8±5.3)min(P<0.05)。对照组的股外侧皮神经和闭孔神经的阻滞成功率分别为87.3%、82.5%,明显低于研究组的98.4%、95.2%(P<0.05)。两组股神经的感觉阻滞起效时间和阻滞成功率差异无统计学意义。结论超声引导下髂筋膜间隙不同角度多点阻滞较单点阻滞起效迅速,神经阻滞成功率高。更多还原

【Abstract】 Objective To compare the effects of ultrasound-guided fascia iliaca compartment block of the single and multiple injection.Methods One hundred and twenty five patients undergoing hip replacement,ASA Ⅰ orⅡ,67 patients were male and 58 patients were female.Patients were randomized to receive ultrasound-guided fascia iliaca compartment block by single injection(control group,n=63)or multiple injection(experimental group,n=62).Local anesthetics using 150 mg ropivacaine combined with 7.5mg dexamethasone.Consumption of local anesthetics was 30 ml.We evaluated the onset time of sensory block and the success rate for block of the femoral nerve,the obturator nerve and the lateral femoral cutaneous nerve.Results The onset time of sensory block for the lateral femoral cutaneous nerve(9.1±3.6)min and the obturator nerve(9.2±3.6)min were shorter in experimental group than that in control group [(11.2±4.7)min &(13.8±5.3)min](P<0.05).The success rate for the lateral femoral cutaneous nerve block(87.3%)and the obturator nerve block(82.5%)in control group was significantly lower than that of experimental group(98.4% &95.2%)(P<0.05).However,there was no significant difference on the success rate of femoral nerve block between two groups.Conclusion Ultrasound-guided fascia iliaca compartment block using multiple injection is more effective than single injection.更多还原
