Erector Spinae Block Using a Dexmedetomidine Versus Magnesium Sulfate as an Adjuvant to Bupivacaine

Postoperative Analgesia Clinical Trial

Official title:
Ultrasound Guided Erector Spinae Block Using a Combination of Bupivacaine and Dexmedetomidine Versus Bupivacaine and Magnesium Sulfate for Postoperative Analgesia in Lumbar Spine Surgery

Clinical Trial Summary

This prospective parallel group randomized study will be conducted over 52 adult participants between 20 and 60 years ASA (American Association of Anesthesiologists) I and II undergoing lumbar spine surgery. The participants will be randomly allocated into 2 groups. Group BM (Bupivacaine + magnesium sulfate) will receive bilateral erector spinae block using bupivacaine and magnesium sulfate after induction of general anesthesia, while group BD (Bupivacaine + dexmedetomidine) will receive bilateral erector spinae block using bupivacaine and dexmedetomidine after induction of general anesthesia. Hemodynamic changes will be monitored intraoperatively, and postoperative pain will be assessed using the visual analogue scale in order to assess the need for postoperative analgesia.

Clinical Trial Description

This prospective parallel group randomized study will be conducted over 52 adult participants between 20 and 60 years ASA (American Association of Anesthesiologists) I and II undergoing lumbar spine surgery. The participants will be randomly allocated into 2 groups. General anesthesia will be induced using propofol 1-2mg/kg, fentanyl 2ug/kg, and atracurium 0.5mg/kg. Both groups will receive bilateral erector spinae block Group BM will receive bilateral erector spinae block .A technique that will be performed ultrasound guided to identify the transverse process of T10, and an 18G (gauge) needle will be introduced in plane deep to the erector spinae muscle after which a combination of 20ml bupivacaine 0.25% and 2.5 ml magnesium sulfate. While group BD will receive the same block with the with 20ml bupivacaine 0.25% and dexmedetomidine 1ug/kg. Hemodynamic changes will be monitored intraoperatively, for detection of any variations. Postoperative pain will be assessed every 2 hours following the surgery using the visual analog scale in order to assess the need for postoperative analgesia. Analgesia will be given in the form of nalbuphine 10mg when the visual analog scale is above 4. Patient satisfaction will be measured by a scale from 1-10 the next day. Any complications will be recorded. ;
