Repair of congenital diaphragmatic hernia on extracorporeal membrane oxygenation - observations of a paediatric surgeon.

Abstract

IntroductionCongenital diaphragmatic hernia (CDH) is a defect involving herniation of the abdominal organs into the pleural cavity through an incompletely closed diaphragm. This defect is also accompanied by various types of pulmonary and bronchial hypoplasia and serious anomalies in the pulmonary vascular bed and pulmonary hypertension. Extracorporeal membrane oxygenation (ECMO) is used in extreme cases resistant to standard treatment. There are no reports clearly indicating the optimal time to make a decision about the repair of CDH in paediatric patients on ECMO. In high-risk neonates (with severe hypoplasia and pulmonary hypertension), this repair procedure is postponed until the cardiopulmonary parameters are stabilized and pulmonary pressure reduced.AimTo present the experience of paediatric surgeons regarding congenital diaphragmatic hernia repair in neonates on extracorporeal membrane oxygenation.Material and methodsCDH was surgically repaired in 17 neonates, and of these 7 were on ECMO.ResultsSurgical problems were encountered intraoperatively: positioning of the patient forced by the cannulae inserted in the carotid vessels, significant generalized oedema, significant capillary bleeding from the surgical wound, difficulties with closing the abdominal cavity. The most common postoperative complications included bleeding from various areas.ConclusionsEach surgery in a neonate with CDH on ECMO is a challenge for the whole medical team involved in the procedure.
