The aim of this study will be to compare the effects of morphine versus dexmedetomidine when used as adjuvants to local anesthetic (Ropivacaine) in Erector Spinae Plane Block under ultrasound guidance. A group without an adjuvant will also be compared to the groups.
Erector Spinae Plane Block (ESPB) was first introduced in 2016 as a treatment technique for chronic thoracic neuropathic pain, and rapidly became popular in peri-operative medicine due to its relatively simple technique and low complication rate. It has been also used extensively in thoracic surgery. According to a systematic review, ESPB can be used effectively as part of multimodal analgesia in thoracic surgery since, when used, opioid consumption decreases.
The use of adjuvants has been studied to a limited extent in ESPB. Dexmedetomidine and dexamethasone have been tried as adjuvants in ESPB and it has been shown that dexmedetomidine is more effective in block prolongation and post-operative opioid consumption. According to our knowledge, morphine has not been used yet as an adjuvant for ESPB.
Therefore, the investigators will perform a randomized controlled trial in order to compare morphine and dexmedetomidine as adjuvants in ESPB in elective thoracotomies in terms of intraoperative and post-operative opioid consumption. Intraoperative opioid consumption will be guided by vital signs and Nociception-Level Index (NOL) and post-operative opioid consumption will be measured by the amount of morphine consumed by the patient during the first 48 hours post-operatively. Secondary outcomes will also be recorded.
