Abstract:
Objective To explore the key points of anaesthetic management of bilateral lung transplantation treating severe idiopathic pulmonary arterial hypertension.Methods Clinical data of 20 cases with severe IPAH treated by bilateral lung transplantation were analyzed retrospectively, 2 males and 18 females, ASA physical status Ⅲ or Ⅳ.The hemodynamic changes were observed at various points (30 min after double lung ventilation, 15 min after ECMO, during one-lung ventilation, 30 min after pulmonary artery block, at the opening of pulmonary artery and at the end of surgery) and pre-and post-operative changes of cardiovascular morphology were analyzed with heart ultrasound.Results Compared with 30 min after double lung ventilation, PaO2 and SVV were significantly increased and PAP, PAWP and PaCO2 were decreased 15 min after extracorporeal membrance oxygenation (ECMO) (P<0.05).PAP and PAWP were significant higher and SVV was lower 30 min after pulmonary artery block than 15 min after ECMO (P<0.05).Opening of pulmonary artery had significantly increased SVV and reduced PAP and PAWP compared with pulmonary artery block (P<0.05).ECMO was removed in 4 cases at end of the surgery.The remaining 16 cases assisted by ECMO were transferred to ICU, 3 cases underwent thoracotomy for exploration and hemostasis 1 day after the operation while 13 cases suffered from different degrees of left heart dysfunction postoperatively, 4 of which had acute heart failure.Of the 4 cases, 2 were treated by right femoral vein-right femoral artery bypass (V-A ECMO bypass) and 2 underwent right femoral vein-right internal jugular vein bypass (V-V ECMO bypass).Moreover, 3 cases performed tracheotomy 5 days, 6 days and 13 days day after the operation, respectively.All the patients were cured and discharged.Their cardiovascular morphology was improved.Conclusion The key successful factors of IPAH treated by bilateral lung transplantation are to improving perioperative heart function, keeping stable hemodynamics during induction of anesthesia and the operation and using ECMO properly and postoperative support.
