23. Evaluation of the impact of anesthesia on hearing in surgical patients
Main Article Content
Abstract
Postoperative hearing loss is a rarely reported phenomenon. However, this phenomenon had been increasing lately Postoperative hearing loss can be unilateral or bilateral, transient or permanent, and has been reported with most anesthetic techniques. The study was conducted on 25 patients receiving endotracheal anesthesia at Hanoi Medical University Hospital after abdominal surgery. The patient's hearing capacity was evaluated 1 day before surgery, 1 day, 1 week, and 1 month after surgery. Results: Characteristics of study subjects: 18 women, 7 men, age range: 24 - 68 years old, most common age is 40 - 50 years old, accounting for 67.2%. Fentanyl 0.5mg, Propofol 1%, Rocuronium bromide 10 mg/ml x 5ml, Ondansetron 8 mg/4ml, Ketorolac 30 mg/1ml were the chosen anesthetics. One day after surgery, 18/25 (72%) patients had hearing loss at different levels, and 25% had sensorineural hearing loss. 11/18 (61.1%) patients had mild sensorineural hearing loss, 7/18 had moderate sensorineural hearing loss. After 1 week, 2 patients had mild hearing loss; after 4 weeks, 1 patient had mild hearing loss. There was close correlation between changes in hearing and anesthesia time R > 1, anesthetic drug R > 1.2 and recovery time after surgery > 0.9.
