Tympanum; Perforation Clinical Trial
Official title:
General Anesthesia With or Without Local Ear Block in Middle Ear Surgeries; A Randomised, Double-blind Trial
Background: Proper selection of anesthetic technique is important in middle ear microsurgery.
Controlled hypotension in ear surgery decreases blood loss with improved quality of the
surgical field, however, it is associated with resistance to vasodilators and delayed
recovery from anesthesia. The use of local anesthetic technique alone in middle ear surgery
decreases bleeding and reduces postoperative pain, however, pain on injection, noise, and
head‑neck position had been reported with the increased risk of patient injuries.
This study aimed to compare the effects of local ear block combined with general anesthesia
versus general anesthesia alone, regarding intraoperative hemodynamics, anesthetic
consumption, recovery characteristics, postoperative pain, adverse effects and postoperative
complications.
Eighty adult patients undergoing middle ear surgery (tympanoplasty with or without mastoidectomy) were enrolled in the study. Patients were randomized into two equal groups (40 patients each). A standardized general anesthetic technique was used in both groups. Group I, received general anesthesia combined with ear block using 10 ml of 0.25% bupivacaine and (Group II), received general anesthesia alone combined with ear block using 10 ml saline. Propofol 2-3 mg /Kg was administered to induce anesthesia, which was maintained using isoflurane. Hemodynamic variables, surgical conditions including the quality of the operative field, intraoperative fentanyl, vasodilators (propranolol and nitroglycerine), isoflurane consumption, recovery time, postoperative pain, total analgesics consumption and postoperative complications were recorded ;
