简要总结
participants were randomly divided into three groups : group 30 , group 40 and group 50 . for all the three groups an ultrasound guided supra-inguinal fascia iliaca block had been performed.
for group 30 ,a volume of 30 ml of 0,2 % ropivacaine had been injected for group 40 ,a volume of 40 ml of 0,2 % ropivacaine had been injected for group 50 ,a volume of 50 ml of 0,2 % ropivacaine had been injected
详细描述
participants were randomly divided into three groups : group 30 , group 40 and group 50 . for all the three groups an ultrasound guided supra-inguinal fascia iliaca block had been performed.
A linear ultrasound probe was placed in the sagittal plane to obtain an image of the superior iliac spine.the fascia iliaca and sartorious,iliopsoas,and oblique internal muscles were identified by sliding the probe medially. After identifiying the "bow-tie sign"formed by the muscle fascias , an 50 mm needle was introduced 1-2 cm inferior to the inguinal ligament.using an in-plane approch, the fascia iliaca was penetrated and hydrodissected , separating the fascia iliaca from the iliac muscle. in this created space a total volume of 30 ml, 40ml or 50ml of 0.2% ropivacaine was injected , respectively to group 30 ,group 40 and group 50 .
pain score at rest and with a straight leg raise of the affected limb to 15 degrees were assessed before and 30 minutes after block performance.
