Abstract
Objective: To investigate any relationship between the pathological features of amiodarone-induced pulmonary toxicity (APT) and clinical use of amiodarone in patients dying from acute respiratory distress syndrome (ARDS).
Design: Retrospective study. Review of clinical and pathological findings of patients dying from ARDS.
Setting: Intensive Care Unit (ICU) and Pathology Department of University hospital.
Subjects: Ten patients with clinical diagnosis of ARDS, who died in ICU and underwent post mortem examination.
Interventions: Case note review of clinical details; independent review of histological specimens.
Measurement and results: Over a 3-year period, ten patients underwent post mortem examination, of whom seven had received amiodarone. Three patients who received longer than 48 h of amiodarone had histological changes of widespread lipoid pneumonia, a recognised pattern of APT.
Conclusions: Acute amiodarone pulmonary toxicity is a definite pathological entity in ICU patients. High oxygen concentrations may be a risk factor, while pre-existing pathology, e. g. ARDS, may mask its development. Amiodarone should be used with caution in this group of patients.
