[Postoperative re-expansion causing unilateral pulmonary edema]

A case of re-expansion pulmonary oedema is reported. A 7-year-old girl, after having been operated on for a lung tumour, had a postoperative haemothorax combined with atelectasis of the left upper lobe. After she had recovered from the first dose of chemotherapy, the thoracotomy wound was reopened to remove the partially organised and lysed haemothorax, as well as the very thickened pleura. The patient developed clinical signs of pulmonary oedema very shortly after the end of the anaesthetic (tachypnoea, cyanosis, a decrease in oxygen saturation when FIO2 < 1, pink frothy secretions in the endotracheal tube). End-inspiratory crepitations became audible in the left lung field only. The chest film showed left-sided diffuse nodular alveolar opacities. The girl was again ventilated, with + 5 cmH2O positive end-expiratory pressure. She was extubated 36 h later, and discharged a few days later without any sequela. This case was the first to be described in a child after pleural surgery. The death rate, estimated from a literature survey, is about 20%.
