Comparing Fascia Iliaca Compartment Block and Pericapsular Nerve Group Block for Hip Fracture Pain Control

The aim of the study is to compare the analgesic effect of fascia iliaca compartment block (FIC) block and pericapsular nerve group (PENG) block in hip fracture pain control. The participants, caregivers, and assessors will be blinded to the type of block the participants receive. Patients aged 20 years or older with hip fracture scheduled for surgical treatment will be assessed for eligibility to participate the study. One hundred eligible patients will be included in the study after informed consents are obtained, and then randomly allocated into either FIC block or PENG block, with 50 patients in each group. Both blocks will performed under ultrasound guidance. The followings will be assessed: the numerical rating pain scale (NRS 0-10, 0: no pain, 10: worst pain imaginable) at before and after nerve block at different time points during rest and passive internal rotation of the fractured lower limb to neutral position from its typical external rotation deformity 30 mins after block (primary outcome). The degree of patient's satisfaction regarding nerve blocks and anesthesiologist's satisfaction regarding patient position during spinal anesthesia will also be assessed. The pain and use of rescue analgesics in the first 24 hours after operation will be recorded.
