Pneumonia due to aspiration of povidine iodine after preoperative disinfection of the oral cavity

Povidone-iodine (PI) is thought to be an effective disinfectant and safe for many surgeons. Aspiration pneumonia is usually caused by gastric contents, but if PI solution will be aspirated, pneumonia or other complications may occur.
We present a case of pneumonia to aspiration of PI solution in a 91-year-old man patient who underwent oral-maxillofacial surgery. When surgeons used PI solution for disinfection into the oral cavity, the solution seems to be sinking gradually. The patient showed severe respiratory distress and developed hypoxia. There were much frothy fluids into a tracheal tube. We suctioned through the endotracheal tube and performed bronchoscopy, that revealed a redness which appeared associated to a chemical injury on the left trachea and bronchus. His condition was complicated by ARDS and DIC. Periodical bronchial suction and guideline-based treatments of ARDS were carried in ICU. He recovered without severe complication.
Although PI solution for an oral disinfection is used routinely, all operators need to be aware of the risk for PI aspiration
