This prospective observational single-center study will compare the effects of ultrasound-guided meta-PENG block and suprainguinal fascia iliaca plane block in patients undergoing hip fracture surgery under spinal anesthesia.
Hip fracture surgery can cause significant pain before, during, and after the operation. Regional anesthesia techniques may help reduce pain, improve positioning for spinal anesthesia, decrease the need for additional analgesics, and support earlier mobilization.
Patients included in the study will be adults scheduled for hip fracture surgery under spinal anesthesia. According to routine clinical practice and the anesthesiologist's decision, patients will receive either ultrasound-guided meta-PENG block or ultrasound-guided suprainguinal fascia iliaca plane block. The study will not assign patients to a treatment group by randomization.
The main outcome will be pain during positioning for spinal anesthesia, measured using the Numeric Rating Scale. Additional outcomes will include postoperative pain at rest and during activity, additional analgesic consumption, patient satisfaction, mobilization time, and length of hospital stay.
