Assessment of nasal mucociliary clearance in anesthetists

Abstract

Materials and methods: The first group consisted of 30 anesthetists who had been working at least 2 years. The control group of 30 subjects was selected from hospital staff with no history of occupational exposure to waste anesthetic gases. Mucociliary clearance time was assessed by measuring the saccharine nasal transit time (SNTT). Background/aim: To assess mucociliary clearance in anesthetists who were exposed to waste anesthetic gases occupationally. Results: Thirty-six women and 24 men aged between 25 and 60 years were enrolled in the study. There were no differences between the anesthetist and control groups in terms of age, sex, height, or weight. The median SNTT for the anesthetists (10 min) was longer than that for the control group (8.3 min). The difference was significant (P = 0.025). In addition, there was a significant correlation between the SNTT and the working time (P = 0.02). Furthermore, anesthetists who had worked for 4 years or more had prolonged SNTT compared to those who had worked less than 4 years (P < 0.001). Conclusion: The present study demonstrated the impairment of mucociliary clearance in anesthetists. Increasing impairment with increasing working time was also detected.
