OBJECTIVE: The aim of this study was to evaluate the effects of sugammadex and neostigmine used in general anesthesia on postoperative mucociliary clearance.

PATIENTS AND METHODS: This prospective, randomized and double-blind study was performed on 60 non-smokers with ASA I-III underwent inguinal hernia repair under general anesthesia. Mucociliary clearance was assessed by nasal saccharine transit time (STT). After the preoperative STT measurement, the patients were taken to the operating room, and divided into two equal groups as group 1 and 2 (n= 30 for each group). Midazolam, propofol, and rocuronium were used in all patients. Anesthesia was maintained by sevoflurane at a flow rate of 6 lt/min (50% O2 – 50% N2O) with a minimum alveolar concentration of 1.3-1.5. After the surgical procedure, atropine-neostigmine (20 mcg/kg – 50 mcg/kg) and sugammadex (2 mg/kg) were administered to group 1 and group 2, respectively, and then the patients were extubated. The postoperative STT was measured in postoperative period.

RESULTS: The mean age of the patients was 53 (±16) years, and 56 (93%) of them were male. There were no differences between the groups in terms of age, gender, height, weight, ASA score, and duration of anesthesia, duration of surgery, postoperative period, preoperative STT, and postoperative STT. However, when each group was evaluated separately, there was a statistically significant increase in the postoperative STT compared to the preoperative STT in both groups (p=0.005 for group 1, p<0.001 for group 2).

CONCLUSIONS: The effects of sugammadex and neostigmine used in general anesthesia on postoperative mucociliary clearance are similar, and postoperative mucociliary clearance is delayed.
