Environmental safety during the administration of Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC)

Abstract

AbstractBackground:Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC) is an innovative technique for intraperitoneal drug delivery. This study investigates the efficacy of the occupational health safety measures taken to prevent exposition of healthcare workers to the toxic chemotherapy aerosol.Methods:Air samples were taken at the working place of the surgeon and of the anesthetist during 2 PIPAC procedures and analyzed for content of platinum by inductively coupled plasma mass spectrometry (ICP-MS). Airborne particles were quantified in real time. Biological monitoring was performed in two surgeons after 50 PIPAC by examining blood samples for possible traces of platinum. Analysis was performed by an independent company.Results:Safety measures included tightly closed abdomen, operating room (OR), ventilation meeting requirements of ISO norm 14644–1 class 5, closed aerosol waste system and remote control of PIPAC administration. No traces of platinum were found in the air of the OR (detection limit of 0.0001 mg/filter). No specific rise in particle concentration was detected in the air during the PIPAC procedure, patient closure and removal of the sterile drapes. Blood samples of the surgeons showed no traces of platinum.Conclusions:After implementation of adequate safety measures, no signs of environmental contamination or biological exposure of the surgeons were detected during PIPAC.
