Postoperative Analgesia Outcomes Of Pericapsular Nerve Group Block (PENG Block) Combined With Lateral Femoral Cutaneous Nerve Block After Hip Replacement Surgery: A Randomized Controlled Study
In Brief
A clinical study evaluating PERICAPSULAR NERVE GROUP BLOCK COMBINED WITH LATERAL FEMORAL CUTANEOUS NERVE BLOCK for POSTOPERATIVE ANALGESIA. Completed, enrolled 60 participants across 1 site.
Detailed Summary
Background: this study aimed to describe the pain relief outcomes after hip replacement surgery by continuous Pericapsular Nerve Group Block (PENG Block) in combination with lateral femoral cutaneous nerve (LFCN) block under the guidance of ultrasound. Methods: patients who had hip surgery at E University hospital, Hanoi, Vietnam from August 2021 to August 2022 belonged to two groups: group of patients with pain relief with PENG block in combination with LFCN block (PENG BLOCK group) and group of patients with patient-controlled intravenous analgesia (PCA group). Outcomes regarding clinical and pain score from initiation of insertion or PCA insertion (H0) to after 72 hours (H72) were recorded.

Timeline
Interventions
During and after the surgery, a group of patients received intravenous morphine analgesia via PCA (concentration 1mg/ml, bolus dose of 1mg, lock time 10 minutes, maximum dose 10mg/4 hours). The remaining group of patients receive pain relief by PENG block and LFCN block. In this group, the ultrasound probe was placed horizontally from the anterior superior iliac spine, and was moved along the femoral arc defining the pubic spine. Then, the transducer was rotated 45 degrees, moved parallel to the femoral arch identifying the anterior inferior iliac spine (AIIS), iliopubic eminence (IPE) and inferior lumbosacral head. The ultrasound probe was moved lightly until the upper end of the femoral head was identified. Next, a 120 mm Tuohy 18G anesthetic needle was used under ultrasound guidance, which was moved lateral to medial in the plane between the ultrasound transducer and the superior tip of the femoral head. Then, 10 mL of ropivacaine 0.25% was injected through the anesthetic needle tip
