Interventions
peng block
A convex ultrasound probe (frequency 2-5 MHz) was positioned at the patient's inguinal ligament, with one end directed toward the anterior inferior iliac spine (AIIS), clearly visualizing the bony prominences of the iliopubic eminence and the AIIS. The needle tip was directed medially toward the pectineus muscle. Upon reaching the space between the pectineus muscle and the pubic bone, and after confirming the absence of blood on aspiration, 30 ml of 0.375% ropivacaine was injected.
obturator nerve block
An ultrasound probe was positioned at the inguinal ligament, with the needle inserted parallel to the long axis of the probe. After confirming no blood upon aspiration, 15 ml of 0.375% ropivacaine was injected into the fascial plane between the adductor brevis and adductor magnus, as well as into the midportion of the adductor longus and adductor brevis muscles.
