A Randomised Controlled Trial to assess the postoperative analgesic efficacy of Fascia Iiliaca Block Versus Pericapsular Nerve Group (PENG)Block in patients undergoing hip fixation surgery

Hip fracture is a common orthopedic emergency in the elderly and is associated with significant morbidity and mortality, surgical reductions and fixations are the definitive treatments in most patients. Adequate pain relief is essential in the postoperative period .  Initially intravenous patient controlled analgesia and epidural analgesia were used . these have been replaced by various peripheral nerve blockade techniques ; these include lumbar plexus block , psoas compartment block , femoral nerve block and so on . Recently fascia iliaca block and (Pericapsular Nerve Group ) PENG block have been proposed for the same ,but there has been no comparative study regarding the two blocks . These peripheral nerve blocks have been found to be associated with reduced motor blockade , early ambulatory outcomes , adequate analgesia  and decreased requirement of opioids .

This study is a randomized controlled trial to assess the efficacy of fascia iliaca and PENG block in the postoperative period. The selection of the patients for the block will be done by computer generated random table and   both the blocks will be given preoperatively  and catheter will be placed at the site of the block and infusion pumps containing the drugs will be attached to the catheter. The surgery will be done under spinal anaesthesia and the catheter will be placed for 48 hours postoperative duration.

Following observations will be made

1.  Mean NRS ( Numerical Rating Scale) score at 0 , 4,8,12, and 24 hours postoperatively

2. Change in NRS score while positiong for spinal anaesthesia

3. Mean dosage of 24 hours postopearive analgesic requirement

4. Proportion  of catheter and drug related complications

Data will be collected and compiled in an excel sheet and will be analyzed statistically .
