Bochdalek hernias in infants: factors determining mortality
Insights
Bochdalek hernia repair outcomes show that infants admitted within 8 hours have the highest mortality. Recent increases in mortality are linked to severely ill infants requiring advanced respiratory support.
Area of Science:
- Pediatric Surgery
- Neonatal Care
- Congenital Abnormalities
Background:
- Bochdalek hernia is a congenital defect requiring surgical intervention.
- Early diagnosis and management are critical for infant survival.
Purpose of the Study:
- To analyze surgical repair outcomes for Bochdalek hernias in infants.
- To identify factors associated with mortality and explore potential interventions.
Main Methods:
- Retrospective review of 76 infant surgical repairs from 1950-1974.
- Analysis of patient demographics, admission timing, and clinical characteristics.
Main Results:
- Mortality was exclusively observed in infants admitted under 30 hours of age.
- Highest mortality rates were seen in infants admitted within the first 8 hours.
- A recent increase in mortality correlated with intubated infants with large defects and hypoplastic lungs.
Conclusions:
- Infant admission timing is a critical prognostic factor for Bochdalek hernia repair.
- Severely compromised infants present unique challenges impacting survival.
- Careful consideration of pre-arrival intubation is advised.
Abstract:
From 1950 through 1974, 76 infants with Bochdalek hernias have been surgically repaired. Mortality has been confined to those admitted at under 30 hr of age, and the highest mortality has been among those infants admitted within the first 8 hr of life. A recent increase in mortality is explained by the arrival of a new group of infants who arrived intubated, had large diaphragmatic defects, required postoperative ventilatory assistance, and had hypoplastic lungs at autopsy. Six infants might have benefited from an early intervention to hasten closure of their patent ductus arteriosus. Since we cannot be positive that intubation of these infants prior to arrival will not have a deleterious effect, we urge great discretion in choosing which infants to intubate.
