This study aims to evaluate the role of dexmedetomidine as an adjuvant in external oblique intercostal plane block for post-thoracotomy pain.
External oblique intercostal plane block (EOIPB) is a novel block that has been described as an important modification of the fascial plane blocks that can consistently involve the upper lateral abdominal walls.
Dexmedetomidine is a selective alpha 2- adrenoceptor agonist possessing sedative, anxiolytic, and analgesic properties without the development of respiratory depression.

Rescue analgesia of morphine will be given as 3 mg bolus if the numeric rating scale (NRS) > 3 to be repeated after 30 min if pain persists until the NRS < 4.
| 48 hours postoperatively |
| Degree of pain | Each patient will be instructed about postoperative pain assessment with the numeric rating scale (NRS). NRS (0 represents "no pain" while 10 represents "the worst pain imaginable"). NRS will be assessed at 0, 4, 8, 12, 18, 24, 36 and 48 h postoperatively. | 48 hours postoperatively |
| Heart rate | Heart rate will be recorded preoperative, before performing of block, and every 15 min till the end of surgery. | Every 15 min till the end of surgery |
| Mean arterial pressure | Mean arterial pressure will be recorded preoperative, before performing of block, and every 15 min till the end of surgery. | Every 15 min till the end of surgery |
| Incidence of adverse events | Incidence of adverse events such as pneumothorax, local anesthetic systemic toxicity (LAST), bradycardia, hypotension, nausea, vomiting, respiratory depression, or any other complication will be recorded. | 48 hours postoperatively |
