Comparing The Effectiveness Of Pericapsular Nerve Group (PENG) Block Versus Supra-Inguinal Fascia Iliaca Compartment Block(S-FICB) In Reducing Positional Pain During Neuraxial Anaesthesia In Hip Fractures Patients

Fractures in and around the hip are common in the elderly and most of them required early surgical fixation. Hip fractures are accompanied with a considerable amount of pain. Based on National Orthopaedic Registry Malaysia (NORM), spinal/neuraxial anaesthesia makes up 66.3%, is the preferred mode of anaesthesia. Severe pain associated with fractured hip often results in difficulty during positioning for neuraxial anaesthesia and hence it is extremely challenging to position the patients in sitting or lateral position for neuraxial anaesthesia procedures. A supra-inguinal fascia iliaca compartment block (S-FICB), a 3 in 1 block involving femoral nerve , lateral femoral cutaneous nerve and obturator nerve. It is famous technique among anaesthesiologist to treat immediate and postoperative pain in hip fractures patients. The pericapsular nerve group (PENG) block is an ultrasound-guided approach, first described by Giron-Arango et al. in 2018 for the blockade of the articular branches of the femoral, obturator and accessory obturator nerves that provide sensory innervation to the anterior hip capsule. It is an alternative regional anaesthesia technique for the management of acute pain after hip fracture. The goal of this clinical trial is to compare the effectiveness of (PENG) block vs (S-FICB) block in reducing positional pain during neuraxial block in patients going for elective internal fixation of neck of femur fractures. And investigators's hypothesis is PENG block is as effective as S-FICB in reducing positional pain during neuraxial block in patients going for elective internal fixation of neck of femur fractures.
