目的了解医院层流洁净手术部运行初期,对医务人员身体产生的危害因素提出预防控制措施。方法通过调查分析一起由医院层流洁净手术部运行初期引起的医务人员身体不适的原因,采用现场卫生学调查与实验室检测相结合的方法进行综合分析。结果未能严格执行操作规程,导致动态下手术室内麻药七氟醚残留(1.56~1.78 mg/m~3)是引起医务人员不适的主要原因;部分室内虽然受到苯的污染(分别是1.70 mg/m~3和0.16mg/m~3),经临床症状及体检结果、实验室检测结果、接触史及流行病学分析,不是引起本次事件的主要原因;排除环氧乙烷、甲苯、二甲苯、甲醛、CO和CO_2中毒。结论要确保层流洁净手术室的使用安全,必须重视使用前的全面调试,使检测结果符合相关标准要求;医务人员必须熟悉层流洁净手术室的工作流程,严格执行操作规程;落实专人负责层流洁净手术室的维护和管理。
Objective To understand the operation of the laminar flow clean operation department in the hospital and put forward preventive and control measures on the health hazards of the medical staff. Methods By analyzing and analyzing the causes of medical staff discomfort caused by the operation of clean laminar flow surgical department in the hospital at the beginning of the operation, a comprehensive analysis was made on the combination of on-site hygiene investigation and laboratory testing. The results failed to strictly enforce the operating procedures, resulting in dynamic intraoperative anesthetic sevoflurane residues (1.56 ~ 1.78 mg / m ~ 3) is the main cause of medical staff discomfort; part of the indoor although benzene contamination (1.70 mg / m ~ 3 and 0.16mg / m ~ 3). The clinical symptoms and physical examination results, laboratory test results, exposure history and epidemiological analysis were not the main reasons for this incident. Ethylene oxide, toluene, Toluene, formaldehyde, CO and CO_2 poisoning. Conclusion To ensure the safe operation of laminar flow clean operating room, we must attach importance to the comprehensive commissioning before use to make the test results comply with the relevant standards. The medical staff must be familiar with the workflow of laminar clean operating room and strictly enforce the operating procedures. Clean operating room maintenance and management.
