Abstract

This study was a cross-sectional analytical study. The purposes were (1) To describe association between nitrous oxide exposure and health effects of operating room personnel. (2) To describe prevalence of health effects of nitrous oxide exposure in operating room personnel. The data was collected by health questionnaire and environmental monitoring of nitrous oxide concentration in operating rooms in a tertiary hospital, Nakhon Ratchasima province between May 2021 and May 2022.  There were 80 personnel in this study divided into 33 operating room personnel and 47 internal medicine personnel.

The results showed that the most health effect of operating room personnel was headache (57.6%) followed by dizziness (27.3%) and drowsiness (33.3%). Nitrous oxide exposure was statistically significant risk factor of dizziness (Odds Ratio = 4.20; 95% CI; 1.295-13.617) and tachycardia (Odds Ratio = 10.22; 95% CI; 1.168-89.500). The concentration of nitrous oxide exposure at 37.5-50 ppm and above than 50 ppm was associated with dizziness, nausea and vomiting, paresthesia, tingling, muscle weakness, delayed reaction time, decrease drive skill, arrhythmia, infertility, and spontaneous abortion more than the concentration of nitrous oxide exposure 5-25 ppm. Therefore, it is necessary to health questionnaire screening including nervous system, cardiovascular system, and reproductive system in periodically medical surveillance. Additionally, exposure monitoring and controlling the nitrous oxide concentration should be lower than national standard and Thai laws.
