[Recruitment maneuver and high PEEP in a patient with severe reperfusion pulmonary edema after pulmonary thromboendarterectomy].
Recently open lung approach such as recruitment maneuver and high PEEP has been applied in patients with acute respiratory distress syndrome. We report here a 29-year-old man with chronic pulmonary thromboembolism (CPTE). In this case, recruitment maneuver and high PEEP relieved postoperative respiratory failure. The major complications after pulmonary thromboendarterectomy (PTE) for CPTE are: reperfusion pulmonary edema (RPE), pulmonary hypertension (PH), hypoxia and bronchial bleeding, all of which the patient has demonstrated. Preoperative examination showed high pulmonary artery pressure (85/41, mean 50 mmHg), and high pulmonary vascular resistance predicted poor postoperative course. After PTE, he developed severe RPE, PH, hypoxia and bronchial bleeding, resulting in failed weaning from cardiopulmonary bypass. Therefore he required mechanical support of percutaneous cardiopulmonary support (PCPS). In ICU we repeated recruitment maneuver (PEEP: 30 cmH2O, peak inspiratory pressure: 42 cmH2O, respiratory rate; 15 breaths.min-1, for 1 min) and kept high PEEP (15 cmH2O). After initiating this ventilatory strategy, RPE was gradually relieved, followed by improvement of oxygenation and PH. We successfully weaned him from PCPS 38 hr after surgery and he was discharged alive on the 90 post-operative day. We conclude that recruitment maneuver and high PEEP may be useful for RPE developed after PTE.
