Treatment of mediastinal infection by continuous closed irrigation with an antibiotic solution in a new bone baby

: The patient was a three-week-old girl. Four days after thoracic surgery, mild fever developed, and turbid fluid was drained from the incision. Culture of the discharge showed Pseudomonas aeruginosa and Serratia marcescens. Debridement was immediately performed and continuous closed irrigation with an antibiotic solution started and maintained for 17 days. During this period, the upper half of the body was elevated. Ten days after irrigation started culture of the drainage fluid became negative. We emphasize early diagnosis, and the usefulness of continuous closed irrigation with an antibiotic solution in neonates.
