Knowledge of Anaesthesia Providers on Exposure to Inhalational Anaesthetic Agents in Ghana

Abstract

Background: Chronic exposure to inhaled anaesthetic agents poses an occu-pational hazard related to the practice of anaesthesia. Therefore, this study sought to find out the perception of anaesthesia providers on exposure to in-halational anaesthetics, evaluate their knowledge on the effects of chronic ex-posure and strategies to reduce chronic exposure to operating room inhala-tional anaesthetic agents. Method: This cross-sectional survey was conducted by administering a self-administered questionnaire to 71 anaesthesia provid-ers in Ghana who attended the annual refresher course of the faculty of Anaesthesia, West African College of Surgeons, in 2016. Data collected were analysed and presented as frequencies and percentages. Results: Halothane and isoflurane were the most frequently used inhalational agents by the res-pondents. Majority (90.1%) of the respondents perceived they are exposed to inhalational anaesthetics in their working environment. Majority of the anaes-thetic providers cited poorly functioning scavenging systems (28.2%) and use of paediatric Ayre's T-piece (28.2%) as sources of exposure to inhalational anaesthetics. All respondents admitted making attempts to reduce their ex-posure to inhalational anaesthetics. Majority of the respondents mentioned teratogenicity (77.5%) and hepatotoxicity (67.6%) as effects of chronic expo-sure to inhaled anaesthetic agents. Conclusion: Anaesthesia providers in Ghana perceived they are chronically exposed to inhalational anaesthetic agents in their work environment. They are aware of the sources of inhala-tional anaesthetic agent exposure, associated health risks and strategies requi-red to reduce chronic exposure to inhaled anaesthetic agents.
