pericapsular nerve group block

Details and patient eligibility

About

the goal of this clinical trial is to evaluate the analgesic effect of pericapsular nerve group (PENG) block in elderly patients with hip fractures undergoing hip surgery .

and to evaluate its effect in reducing post operative complications .

Full description

all patients meeting the inclusion criteria will be informed about the study goal , methods and procedure in clear language. a written informed consent will be taken.

All patients ,once arrived to the OR, monitor will be attached, spinal anesthesia will be performed as follows, after sterilization of the back with bovidon iodine, local anesthesia 3cc of lidocaine 20% will be injected at the level of L3-L4 spine , then injection of 17 mg bupivacaine 0.5% through a 25 spinal needle.

At the end of surgery,all patients will receive PENG block through ultrasound. The regional block was performed with the patient in the supine position. A curvilinear low-frequency ultrasound probe (2-5MHz) was initially placed in a transverse plane over the AIIS and then aligned with the pubic ramus by rotating the probe counterclockwise approximately 45 degrees. In this view, the IPE, the iliopsoas muscle and tendon, the femoral artery, and pectineus muscle were observed. A 22-gauge, 80-mm needle was inserted from lateral to medial in an in-plane approach to place the tip in the musculofascial plane between the psoas tendon anteriorly and the pubic ramus posteriorly. Following negative aspiration, the local anesthetic solution was injected in 5-mL increments while observing for adequate fluid spread in this plane for a total volume of 20 mL bupivacaine 0.25%.
