Insights

Extracorporeal membrane oxygenation (ECMO) significantly improved survival rates for infants with congenital diaphragmatic hernia (CDH). While most survivors experienced complications like GERD and CLD, neurodevelopmental outcomes at one year were largely average to borderline.

Area of Science:

  • Neonatal Medicine
  • Pediatric Surgery
  • Critical Care

Background:

  • Congenital diaphragmatic hernia (CDH) is a severe condition with historically high mortality rates in neonates.
  • The advent of advanced respiratory support has been crucial in managing these critical cases.

Purpose of the Study:

  • To evaluate the impact of extracorporeal membrane oxygenation (ECMO) on survival rates in infants diagnosed with CDH.
  • To document the short-term medical sequelae and 1-year neurodevelopmental outcomes for CDH infants treated with ECMO.

Main Methods:

  • A cohort of 30 neonates with CDH admitted between 1990 and 1992 was studied.
  • Twenty infants requiring ECMO underwent medical and neurodevelopmental assessments at 3, 6, and 12 months post-discharge.
  • Data on neonatal course, surgical interventions, and follow-up outcomes were collected via chart review and clinical evaluations.

Main Results:

  • The survival rate for CDH infants requiring ECMO was 80% (16 of 20).
  • The overall survival rate for CDH increased from 31% to 63% following the implementation of the ECMO program (P = .01).
  • Common sequelae included gastroesophageal reflux (81%), need for tube feeding (69%), and chronic lung disease (62%). At 1 year, mean cognitive scores were average (87±23), and motor skills were borderline (75±24), with hypotonia in 10 of 13 patients.

Conclusions:

  • ECMO has substantially improved survival for neonates with congenital diaphragmatic hernia.
  • While ECMO facilitates survival, long-term management must address common sequelae such as GERD, CLD, and neurodevelopmental deficits, including borderline motor skills and hypotonia.

Fetal Circulation01:14

Fetal Circulation

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...
Acute Respiratory Failure-V01:29

Acute Respiratory Failure-V

The treatment for acute respiratory failure varies based on factors like the underlying cause, overall health, and severity. A collaborative healthcare team is essential for early detection, often through arterial blood gas analysis. Identifying the cause is the primary goal, with treatment strategies adjusted for ventilation/perfusion (V/Q) mismatch, shunting, or diffusion impairment.
Ensure that patients are monitored continuously for their response to therapy, including changes in...

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned under...
