To Intubate or Not: A Comprehensive Clinical Analysis of Airway Management and Stabilization Strategies for Neonatal Congenital Diaphragmatic Hernia in Resource-Limited Facilities

Abstract

Introduction: Congenital Diaphragmatic Hernia (CDH) remains a formidable challenge in neonatal medicine, particularly in low- and middle-income countries (LMICs) where diagnostic resources and advanced life support modalities, such as extracorporeal membrane oxygenation (ECMO), are often unavailable.¹ This condition, characterized by the herniation of abdominal viscera into the thoracic cavity through a diaphragmatic defect, leads to a critical triad of pulmonary hypoplasia, persistent pulmonary hypertension of the newborn (PPHN), and cardiac dysfunction.³ The immediate postnatal management, specifically the decision to initiate invasive mechanical ventilation versus non-invasive support, is a pivotal determinant of survival.³

Case Illustration: This report details two distinct cases of postnatally diagnosed CDH at a Type C hospital in Bali, Indonesia. Case 1 involves a full-term female neonate (2,900g) presenting with moderate respiratory distress (Apgar 4/5/6), who was successfully stabilized using non-invasive continuous positive airway pressure (CPAP) and orogastric decompression before being referred at 20 hours of life. Case 2 involves a full-term low-birth-weight female neonate (2,325g) with prenatally suspected dextrocardia and severe hypoxemia (SpO2 40%), necessitating prompt endotracheal intubation and pressure-controlled ventilation to achieve physiological stability prior to tertiary referral.

Discussion: The analysis explores the embryological origins of the diaphragmatic defect, occurring between the 4th and 12th weeks of gestation, and the physiological impact on lung development.³ It highlights the utility of the Downes score for clinical monitoring in settings where arterial blood gas analysis may be limited.⁶ Furthermore, the discussion contrasts the "gentle ventilation" strategy with historical hyperventilation approaches and examines the systemic challenges of neonatal transport within the Indonesian healthcare framework.⁷

Conclusion: Individualized airway management is essential in resource-limited settings. While immediate intubation is mandatory for severe hypoxemia, non-invasive stabilization may be appropriate for clinically stable phenotypes, provided meticulous orogastric decompression is maintained.³ Early recognition and standardized referral pathways are critical to improving survival outcomes in these complex cases.⁹
