Pulmonary toxicity of antineoplastic agents: anaesthetic and postoperative implications.
Agents commonly used in the treatment of neoplastic diseases may impair pulmonary function, and a wide spectrum of agents are currently implicated as toxic to the pulmonary system. Agents most commonly implicated are bleomycin, carmustine, busulfan, methotrexate, and thoracic radiotherapy. Less commonly implicated agents include mitomycin, procarbazine, melphalan, chlorambucil, and cyclophosphamide. Therapeutic interactions at time of operation and postoperatively may exacerbate existing pulmonary damage. It is imperative for the physicians treating patients receiving antineoplastic therapy to recognize potentially dangerous therapeutic interactions, and adjust the therapeutic regimen accordingly. Concentrations of inspired oxygen must be maintained as low as is safely possible. Intraoperative monitoring of arterial and mixed venous oxygen tensions will enable the clinician to adjust inspired oxygen concentrations to the lowest possible level while maintaining adequate oxygen tensions to the tissues. A systematic review of antineoplastic agents currently implicated, drug-oxygen interactions, and a review of the pathophysiology are presented.
