[Treatment of mediastinal infection following cardiac surgery by continuous closed irrigation with povidone-iodine in early infancy]. 
Two patients aged 2 months and 9 days with postoperative mediastinal infection were treated by continuous closed irrigation with 0.5% povidone-iodine solution.  Satisfactory eradication was achieved in both two patients.  Although serum iodine level was elevated as high as 7,610 micrograms/dl in the neonatal patient, no disturbances of the thyroid function and the acid-base balance were seen.  The usefulness of continuous closed irrigation in the neonatal or infantile period was suggested.
