Impact of carbon dioxide pneumoperitoneum in operating rooms on the health of medical staffs / 中华劳动卫生职业病杂志

ABSTRACT

Objective@#To evaluate the impact of CO2 pneumoperitoneum in operating rooms on the health of medical staffs.@*Methods@#In June 2016, the thirty-three medical staffs in operating rooms were chosen as the object of the research.Seventeen people who took part in the pneumoperitoneum operation were selected as a exposure group and sixteen people who took part in the laparotomy operation were selected as a control group.Vital signs and arterial blood gases of medical staffs in the two groups were both measured in pre-operation and post-operation. Occupational Health Questionnaires were conducted to collect information on age, weight and postoperative symptoms. The level of CO2 in operating room was determined by a portable infrared CO2 analyzer.@*Results@#Compared with the control group, the concentration of CO2 in the exposed group was higherat T1, T2 and T3 (t=22.227, 13.583, 17.408, P<0.05) . Heart rates and PaCO2 in the exposure group raised greatly (t=2.132, 2.129, P<0.05) , while pH decreased (t=-3.015, P<0.05) . The differences between the two groups were statistically significant.@*Conclusion@#The increase of mild acidosis and thesense of job burnout in medical staffs could be caused by CO2 pollution in the operating rooms.
