A case of prone position combined with iNO therapy under EIT monitoring in the treatment of refractory hypoxemia after lung transplantation

We report a case of severe primary graft dysfunction (PGD) and refractory hypoxemia after bilateral lung transplantation in our center. The effect of conventional therapy of the patient was inadequate, and the patient was unable to be weaned off extracorporeal membrane oxygenation (ECMO). Employing electrical impedance tomography (EIT) monitoring technology, we implemented a series of interventions including prone position, inhaled nitric oxide (iNO) therapy, tracheotomy and other treatment methods. After undergoing a rigorous treatment process, the patient was successfully transitioned out of intensive care unit (ICU) on the 24th day after operation. In conclusion, the utilization of EIT for visual respiratory management, in conjunction with a multifaceted therapeutic approach, substantially contributed to the improved prognosis of lung transplant recipients.
