Role of Dexmedetomidine as Adjuvant With Bupivacaine in Ultrasound-Guided Erector Spinae Plane Block for Postoperative Analgesia After Shoulder Arthroscopy: A Randomized Controlled Study
Role of Dexmedetomidine as Adjuvant With Bupivacaine in Ultrasound-Guided Erector Spinae Plane Block for Postoperative Analgesia After Shoulder Arthroscopy: A Randomized Controlled Study
The aim of this study is to evaluate the effect of adding dexmedetomidine as an adjuvant to bupivacaine in ultrasound (US) guided erector spinae plane block (ESPB) for managing acute postoperative pain in patients undergoing shoulder arthroscopy.
Shoulder arthroscopy is a common procedure done is orthopedics for many surgical indications as rotator cuff tears, stiffness and instability. This procedure has a well - documented postoperative pain. To improve the outcome after surgery, effective pain control is needed.
There are many postoperative pain management modalities after shoulder arthroscopy including non-steroidal anti-inflammatory drugs, intraarticular injection, regional nerve blocks, patient controlled analgesia and cryotherapy.
The erector spinae plane block (ESPB) is one of the emerging regional techniques for managing postoperative pain. ESPB has been used successfully in many surgeries such as mastectomy, thoracotomies , percutaneous nephrolithotomies, lumbar fusions, hernia repair, cesarean delivery and even in total hip arthroplasty .
ESPB has been successfully used to treat chronic shoulder pain, and the local anesthetic spread was reported to reach the level of C3 when it was performed at T2.
Dexmedetomidine is a very selective α2 adrenoceptor agonist that is tenfold more selective than clonidine. It is a highly flexible medication in anesthetic practice, finding use in an expanding range of clinical circumstances.
