Prospective Study Of Local Infiltration Analgesia For Post Operative Pain Control Following Total Hip Replacement

Abstract

Introduction: Local infiltration analgesia has gained popularity in recent past using mixture of drugs for various surgeries. This study was planned to assess the efficacy of local infiltration for total hip replacement based on postoperative outcomes like Visual Analogue Score (VAS), mobilization time and hospital stay. Methods: This prospective study included adult patients undergoing total hip replacement under spinal anesthesia from January 2018 to December 2018. Local infiltration using ropivacaine, clonidine, ketorolac and adrenaline was given at three stages during surgery and postoperatively pain control was assessed using VAS score during rest and movement, mean duration of first walk, mean duration of hospital stay was recorded. The data collected therein was analyzed using SPSS v.22. Results: Pain control was satisfactory in majority of patients with VAS score of 0-3 both during rest and movement. The first assisted walk was between 11.4 to 17.5hrs (mean: 14.14hrs) after surgery. 56% of patients had less than 3 days hospital stay after surgery. Conclusion: Local infiltration analgesia is safe, practical and efficient in pain control after hip surgeries.
