IntroductionProximal femur fractures are common among older individuals and pose challenges in achieving effective post-operative analgesia. Age-related co-morbidities limit the selection of analgesics in this population. This study aimed to compare the safety and effectiveness of transdermal buprenorphine (TDB) patch with traditional analgesics after fixation of an extracapsular fracture of the proximal femur.MethodologyA prospective randomized controlled study was conducted over a 2-year period, involving 60 patients who underwent surgery for extra capsular intertrochanteric fracture fixation. The patients were randomly assigned to two groups by random envelope method. Group A received an intravenous formulation of paracetamol and tramadol for the initial 48 h, followed by an oral formulation. Group B received a transdermal buprenorphine (TDB) patch delivering 5 mcg/hour immediately after surgery, which continued for 2 weeks postoperatively. During the 14-day monitoring period, patients' pain scores were assessed using the Visual Analog Scale (VAS) at rest and during movement. The primary objective was to maintain a VAS score of 4 or lower. Rescue analgesics were administered if the VAS score reached 6. The secondary objectives included evaluating the quantity of rescue analgesics required and monitoring for any adverse effects or complications.ResultsPain scores at rest and during movement were significantly lower in Group B at all-time points (p-value 0.0006 - ≤ 0.0001), and the requirement for rescue analgesia was also significantly lower in this group. The administration of the TDB patch did not result in any significant adverse effects.ConclusionTDB patch is secure and offers better compliance and analgesia than other analgesics in the postoperative period whilst treating proximal femur extra capsular fracture.Copyright © 2024 Elsevier Ltd.
