FURNITURE polish ingestation remains one of the most frequent types of petroleum product intoxication in young children.1 The incidence of pulmonary inflammation is higher after furniture polish ingestion than after ingestion of any other petroleum product.2 The relationship of petroleum product intoxication to pulmonary injury has been attributed to direct parenchymal injury resulting from aspiration and to indirect injury to the alveoli and pulmonary capillaries by the excretion through the lungs from the blood of the absorbed petroleum product.3
The pulmonary changes observed after furniture polish poisoning include hemorrhage, atelectasis, and frothy pulmonary edema. These findings are very similar to lesions associated with alteration of the surface activity of the lining layer of the lung.
This study was designed to evaluate the effect of furniture polish intoxication on the surface active properties of the lungs. Rats and dogs were given furniture polish by various routes and the
