Airborne and surface contamination after rotational intraperitoneal pressurized aerosol chemotherapy using cisplatin.

초록

OBJECTIVE: We evaluated the occupational exposure levels of healthcare workers while conducting rotational pressurized intraperitoneal aerosol chemotherapy (RIPAC) using cisplatin in a large animal model. METHODS: We performed RIPAC using cisplatin in 6 female pigs and collected surface and air samples during the procedure. Surface samples were obtained from RIPAC devices and personal protective equipment (PPE) by wiping, and air samples were collected around the operating table. All samples were analyzed by inductively coupled plasma-mass spectrometry to detect platinum. RESULTS: Among all surface samples (n=44), platinum was detected in 41 samples (93.2%) but not in all air samples (n=16). Among samples collected from RIPAC devices (n=23), minimum and maximum cisplatin levels of 0.08 and 235.09 ng/cm² were detected, mainly because of direct aerosol exposure in the abdominal cavity. Among samples collected from healthcare workers' PPE (n=21), 18 samples (85.7%) showed contamination levels below the detection limit, with a maximum of 0.23 ng/cm². There was no significant contamination among samples collected from masks, shoes, or gloves. CONCLUSIONS: During the RIPAC procedures, there is a potential risk of dermal exposure, as platinum, a surrogate material for cisplatin, was detected at low concentration levels in some surface samples. However, the respiratory exposure risk was not identified, as platinum was not detected in the airborne samples in this study. © 2025.
