Aim: To present the clinical and surgical experiences in extracorporeal membrane oxygenation (ECMO) in patients with congenital diaphragmatic hernia (CDH). Methods: Patients with CDH who underwent ECMO were evaluated for birth weight and week, localization of hernia, hernia, ECMO indications, time to ECMO ventilation and duration of ECMO, results of surgical treatment and complications. Results: Four patients with mean birth week of 37.5 weeks (37-38) and mean birth weight of 3380g (3210-3850g) were included. Male-female ratio is 1:3. Hernia was left sided in 3 patients and right sided in one patient. Although patients received conventional ventilation and treatment of pulmonary hypertension (nitric-oxide, ileomedin, sildenafil) underwent aorta-atrium cannulation for ECMO with a mean time of 2days (1-4days) with abnormal blood gases, oxigenation and pulmonary pressures. Blood gases before ECMO showed mean pH;7.11 (6.63-7.35), PCO2;65.5 (49-83), P02;54.7(36-72) and O2 saturation 81% (74%-88%). When pulmonary pressures were evaluated mean right pulmonary arterial pressure was 59.7mmHg (55-65). CDH were repaired with polytetraflouroethylenne patch via thoracotomy in one case and with laparotomy in three cases during ECMO cannulation. Mean ECMO ventilation time was 34.75 days (11-83 days). One of the cases is still on ECMO at 29th day. During follow-up, two patients developed ischemic bowel perforation and operated with ileostomy in once case and primary suture repair in other. One patient had bleeding and pneumothorax during ECMO ventilation. Patient who underwent ileostomy was died because of sepsis at 15th ECMO day. Three of the cases survived and two of them have still conventional ventilation support (mean 47 days). Conclusion: Initial experiences showed that ECMO is a promising alternative treatment in patients who did not respond to conventional ventilation methods and pulmonary hypertension treatment. Improvement in experiences in ECMO ventilation and development of clinical protocols may reveal decreased ECMO complications and mortality rate in CDH patients.
