Abstract:

Background:
Pain management after total hip arthroplasty is well studied. Nevertheless, there is no consensus regarding the "cocktail" to use in periarticular infiltration (PAI). Liposomal bupivacaine (LB) is a slow release local anesthetic that can be infiltrated during surgery. In this study, we compared LB to bupivacaine hydrochloride (HCL).
Methods:
Between September 2014 and March 2016, 181 patients were screened for this prospective randomized trial. A total of 107 patients were enrolled and studied. Patients were separated into LB and control groups. LB group (50) received PAI with LB and bupivacaine HCL with epinephrine and the control group (57) received PAI with bupivacaine HCL and epinephrine. Patient morphine equivalent consumption, pain score estimated on visual analog scale, time to first ambulation greater than 20 feet, time to discharge, drug-related side effects, and patient falls were documented. Data were collected up to 72 hours postoperation.
Results:
There was no significant difference in morphine equivalent consumption in any of the 12-hour time blocks, up to 72 hours. No patient falls were documented in either group. Time to first ambulation greater than 20 feet, ambulation same day as surgery, time to discharge, and drug-related side effects were not significantly different between groups.
Conlcusion:
Intraoperative PAI with LB did not result in significant differences in postoperative opioid consumption, pain scores, opioid-related side effects, time to first ambulation, and length of stay up to 72 hours following total hip arthroplasty compared to a control group.
