Erector Spinae Block With Ropivacaine and Dexmedetomidine on Opioid Consumption After Lumar Spine Surgeries

Efficacy of Erector Spinae Block With Ropivacaine and Dexmedetomidine on Opioid Consumption After Lumar Spine Surgeries - A Randomised Controlled Trial

The aim of this study is to investigate the role of 0.5 micrograms/kg of dexmedetomidine with 0.2 % ropivacaine in erector spinae block in reducing opioid consumption for patients undergoing lumbar spine surgeries. This study will help in understanding the role of adding dexmdetomidine to ropivacaine in erector spinae block in reducing opioid consumption after lumbar spine surgeries

A number of adjuvants have been used with local anesthetics including dexamethasone, nalbuphine and dexmedetomidine etc with the aim of improving quality and duration of peripheral nerve blocks. Dexmedetomidine is a potent alpha-2 agonist which can prolong the duration of regional anesthesia block when used in combination with local anesthetics. Although, there is no consensus on the dose of dexmedetomidine for peripheral nerve block considering the fact that it can lower heart rate and blood pressure intraoperatively. Investigators therefore, planned this randomised controlled trial to investigate the role of 0.5 micrograms/kg of dexmedetomidine with 0.2 % ropivacaine in erector spinae block for patients undergoing lumbar spine surgeries.

Inclusion Criteria:

• Patients aged between 18 and 70 years, scheduled to undergo lumbar spine surgeries with an ASA score of 1 to 3 will be included in the study

Exclusion Criteria:

• Patients who refused enrollment or later requested removal for the study, those who are unable to give informed consent and patients with either contraindications for regional anesthesia, known allergy to local anesthetics or dexmedetomidine, bleeding diathesis, use of anticoagulants or corticosteroids, inability to operate patient controlled analgesia (PCA) system, psychiatric disorders or use of psychiatric medications will not be included in the study.
