Overview
The aim of this study to evaluate efficacy of ultrasound guided regional anesthesia in performing awake tympanoplasty surgery versus traditional general anesthesia
Description
- To evaluate ultrasound-guided regional anesthesia versus general anesthesia in patients undergoing tympanoplasty as regards:
- To assess the time of discharge from post anesthesia care unit
- To assess intraoperative hemodynamic parameters, quality of the surgical field and the block success rate (number of patients converted to general anesthesia).
- To assess postoperative parameters: Numerical Rating Scale , time to first request of analgesia, postoperative opioid consumption, patient and surgeon satisfaction in both groups.
- To assess the incidence of block-related complications (such as nerve injury, hematoma, inadequate block, or local anesthetic toxicity) or surgery related complications as nausea and vomiting
