Hip and proximal femur fractures, comprising 20% of all fractures in the elderly, are rising due to the aging population. Intense pain associated with proximal femur fractures can be worsened by position changes during examination, transport, or treatment. This augmented pain response can trigger adverse cardiovascular and cerebrovascular complications. 

The Fascia Iliac Block is increasingly used to reduce hip fracture pain. In recent years, USG -a guided supra-inguinal FICB approach has emerged as a novel method for performing FICB. It is safely performed with minimal risk as the needle trajectory does not cross major vessels, and the intended site of drug deposition is relatively superficial. The Supra inguinal approach, a recent advance over the conventional approach, ensures a more consistent spread of Local anesthetics (LA). It provides (80%) sensory blockade of the thigh than the previous method(30%).

The single-shot S-FICB provides analgesia for approximately eight hours, and few other studies show that its effect starts wearing off around 24 hrs. We wanted to prolong the analgesia period by inserting a catheter and providing continuous LA infusion through the elastomeric infusion system without electricity. It gives a consistent supply of drugs and does not require detachment during transportation.

Hence this study is designed to assess and compare the analgesic efficacy of USG-guided single-shot Suprainguinal Fascia Iliaca Compartment Block (S-FICB) to Continuous S-FICB  using a continuous catheter and infusing through an elastomeric infusion pump in elderly patients with proximal femur fracture presenting to to the Emergency Department (ED).
