The Effect of Adding Lateral Femoral Cutaneous Nerve Block to PENG Block on Postoperative Opioid Consumption in Hip Surgery

The incidence of femoral neck fracture in Europe is 330/10000 per year. It is increasing every year due to the aging of the population. In patients 55 years and older, hip fracture-related mortality is estimated to be between 4% and 16% at one month and between 11% and 43% at one year after surgery. The reduced risk of postoperative complications associated with the use of regional anesthesia, shorter mobilization times, and reduced morphine consumption in hip fractures have been reported, and have been incorporated into postoperative pain control as part of multimodal strategies. PENG has been described for postoperative pain control for surgery on the hip joint or for the treatment of post-traumatic pain associated with proximal femur/femoral head fractures. Lateral femoral cutaneous nerve block is used in combination with other peripheral block methods to provide analgesia in the lateral thigh.

The investigators aimed to evaluate the effect of adding lateral femoral cutaneous nerve block to PENG block on pain scores and opioid consumption in femoral fracture procedures under spinal anesthesia.
