As an unintended consequence of these advances, more babies born with malformations such as congenital diaphragmatic hernia (CDH) survive and with more severe malformations than in the past.Dr. Pramod Puligandla discusses a new clinical practice guideline on diagnosis and management of CDH. Dr. Puligandla is a Professor of Paediatric Surgery, Paediatrics and Surgery at McGill University, Faculty of Medicine in Montreal, Quebec.
