Fascia Iliaca Block Successfully Prolonged With Dexmedetomidine and Dexamethasone for Pain Control in a Patient Undergoing Total Hip Arthroplasty

Abstract

Regional anesthesia has found many advocates as enhanced recovery after surgery continues to become a more popular option for procedures such as total hip arthroplasty. Among the many benefits is the better pain control with a reduction or complete elimination of the need for opioids for perioperative pain management. With aims to improve the multi-modal approach to pain management, we present a case demonstrating further improvements in the regional anesthetic technique with the addition of a dexamethasone and dexmedetomidine adjuvant to the local anesthetic injectate. Our case is that of a 65-year-old woman with a history of hypertension, hyperlipidemia, and right hip osteoarthritis undergoing a right total hip arthroplasty who received a preoperative ultrasound-guided fascia iliaca block with the adjuvants dexamethasone and dexmedetomidine added to the injectate. The surgery was uneventful. She did not require any postoperative opioid or non-opioid analgesics, denying any pain for the first three postoperative days.
