OBJECTIVE: To describe the outcome of infants with congenital diaphragmatic hernia (CDH) presenting early who were referred for possible extracorporeal membrane oxygenation (ECMO). DESIGN: Retrospective descriptive study. SETTING: Neonatal Intensive Care Unit of the Royal Alexandra Hospital, Edmonton. PATIENTS: Fifteen infants referred to our program since its introduction, in February 1989; 13 received ECMO. The criterion for ECMO was the presence of an oxygen index of more than 40 on three occasions within 2 hours. INTERVENTION: ECMO was performed by means of cannulation of the right carotid artery and jugular vein for 111.0 hours on average. RESULTS: In 5 of the 13 infants who underwent ECMO the procedure was performed after surgical repair; all were successfully weaned off ECMO, and the cannula was removed without incident. In the remaining eight ECMO was started before surgical repair; of the six who received it during repair four ultimately survived. None of the previously described predictors of outcome for CDH, including diagnosis before 25 weeks' gestation (in six cases), were useful in determining the survival of the patients. Bleeding was the most common complication and cause of death. CONCLUSION: ECMO is associated with survival in infants with CDH who fail to respond to conventional therapy and who have a poor prognosis according to previously established criteria.
This report describes a recipient of single-lung transplantation surviving extraordinary complications: (1) early graft failure mandating retransplantation; (2) left atrial thrombus formation, which resolved by recombinant tissue plasminogen activator lysis; (3) and development of a "locked-in-syndrome." Possible underlying mechanisms are discussed.
It has been suggested that delayed repair with preoperative stabilization might improve survival in high-risk (symptomatic within 6 hours of birth) congenital diaphragmatic hernia (CDH). This study compares the results of immediate operation versus delayed repair using extracorporeal membrane oxygenation (ECMO) when necessary. Since we first used ECMO in 1984, 101 high-risk CDH infants have been treated. Prior to 1987, we used immediate repair and postoperative ECMO if necessary. Between 1987 and 1990 we combined delayed operation (24 to 36 hours) with preoperative ECMO as necessary. No infant in this series was excluded from ECMO therapy unless absolute contraindications existed (prematurity, intracranial hemorrhage, or other major anomalies). Fifty-five patients received immediate operation and 46 had delayed repair. The two groups were comparable populations based on gestational age, birth weight, age at onset of symptoms, Apgar scores, best postductal PO2 (BPDPO2), and frequency of antenatal diagnosis. There was no statistically significant difference in overall survival between the two groups. Differences in survival among subpopulations (BPDPO2 greater than 100 or less than 100, antenatal diagnosis, inborn v outborn) also are not significant. The requirement for ECMO was similar in both groups. Survivors in the delayed repair group were ventilated longer and on ECMO longer, but had fewer late deaths (greater than 21 days) and fewer pulmonary sequelae (O2 dependency at discharge) than infants in the immediate repair group (P less than .05).(ABSTRACT TRUNCATED AT 250 WORDS)
