Analysis of patients with congenital diaphragmatic hernia requiring pre-operative extracorporeal membrane oxygenation (ECMO).

Abstract：

:The purpose of this report was to analyze the patients requiring preoperative extracorporeal membrane oxygenation (ECMO) as the most critical group of patients with congenital diaphragmatic hernia (CDH) and to identify any special features. Over the past 11 years, out of 72 neonates with CDH admitted before 24 h of age, 40 (56%) could be managed with conventional therapies while the other 32 (44%) required ECMO. Seventeen infants requiring preoperative ECMO were classified as group 1, and the 15 with postoperative ECMO as group 2 (controls). The records of patients in both groups were analyzed. Patients in group 1 were not only severely hypoxic, but also significantly hypercapneic on admission, and in 14 (82%) the diaphragmatic defect was so large or totally agenetic that a prosthetic patch was necessary. The average age at onset of ECMO in group 1 was 13.1 h, and the average duration was 159 h. Major hemorrhagic complications including intracranial hemorrhage occurred with a significantly higher frequency in group 1. The survival rate in group 1 was 41%, compared with 73% in group 2 and 85% in non-ECMO patients. Four infants in group 1 with extremely hypoplastic lungs could not be weaned from ECMO, and died without undergoing an operation. Moreover, 4 of the 7 survivors in group 1 required prolonged (105-658 days) ventilator care with a tracheostomy after weaning from ECMO, and were frequently hospitalized thereafter. The pulmonary function of these patients remained severely underdeveloped for a long time; indeed, the average pulmonary perfusion ratio of the affected side remained at only 40% of the contralateral side in group 1, although the volume ratio reached 85%. These findings may suggest that the main pathology of the patients requiring preoperative ECMO was a high degree of pulmonary hypoplasia, and that there will be limitations to management using ECMO.
