Respiratory Distress Syndrome Treatment

Our Approach to RDS Management

Support the breath. Replace the surfactant. Protect the developing lung.

Respiratory Distress Syndrome has a simple underlying mechanism - the immature lung lacks surfactant, the soapy substance that lines the air sacs and prevents them from collapsing between each breath. Without it, the baby must generate enormous negative pressure with every inspiration to reopen collapsed alveoli, quickly exhausting their respiratory muscles and depleting oxygen levels. The treatment, conceptually, is equally simple: replace the missing surfactant and support the breathing until the lungs mature enough to produce it themselves.

The clinical execution of this simple concept, however, demands extraordinary precision - particularly in the most premature and fragile infants. At Shree Hospitals, our approach to neonatal breathing difficulty diagnosis and ventilator care for RDS prioritises gentle, lung-protective strategies from the very first breath, recognising that how we support the lung in the first hours and days directly affects whether it recovers healthily or develops chronic lung disease.

1. Antenatal Prevention - Starting Before Birth
    
   The most effective treatment for RDS begins before delivery:

• Antenatal corticosteroids (betamethasone) administered to the mother when preterm delivery is anticipated - stimulating fetal lung maturation and surfactant production
• A single course of steroids given 24 to 48 hours before delivery reduces RDS severity, need for surfactant, and mortality
• Repeat courses are used selectively, balancing benefit against potential effects on fetal growth
• Delayed cord clamping at delivery - improving cardiopulmonary adaptation in the immediate newborn period
   

2. Immediate Delivery Room Respiratory Support
    

• Positive pressure ventilation initiated gently for babies who don't establish spontaneous breathing - using a T-piece resuscitator with controlled inspiratory pressure
• Sustained inflation technique - a slow, prolonged initial inflation helping to establish functional residual capacity
• CPAP (Continuous Positive Airway Pressure) applied immediately in the delivery room for spontaneously breathing preterm babies - keeping the alveoli open between breaths
• Avoidance of intubation in the delivery room whenever possible - babies managed on CPAP have better lung outcomes than those intubated routinely
   

3. Surfactant Therapy - The Transformative Treatment
    
   Surfactant therapy and CPAP support for newborn RDS in Mumbai at Shree Hospitals:

• Natural bovine-derived surfactant administered directly into the airway via a thin catheter - restoring lung compliance dramatically within minutes
• INSURE technique (Intubate, Surfactant, Extubate to CPAP) - brief intubation for surfactant delivery, immediately returning to CPAP
• LISA technique (Less Invasive Surfactant Administration) - delivering surfactant through a thin catheter while the baby continues breathing on CPAP, minimising intubation-related trauma
• Repeat surfactant dosing when the initial response is incomplete - guided by clinical assessment and chest X-ray findings
• Typically reduces oxygen requirement and breathing difficulty within 1 to 2 hours of administration
   

4. Mechanical Ventilation When Required
    
   For babies with severe neonatal respiratory failure not responding to surfactant and CPAP:

• Conventional mechanical ventilation using lung-protective settings - minimising tidal volumes to prevent ventilator-induced lung injury
• High-frequency oscillatory ventilation for severe RDS or air leak complications - delivering tiny, rapid breath volumes with continuous lung distension
• Volume guarantee ventilation - automatically limiting delivered tidal volume regardless of lung compliance changes, reducing barotrauma
• Permissive hypercapnia strategy - accepting mildly elevated CO₂ to allow lower ventilator pressures
   

5. Supportive NICU Care
    
   Comprehensive support alongside respiratory treatment:

• Temperature regulation in a closed incubator maintaining a thermoneutral environment
• Strict fluid balance management - avoiding excess fluid worsening pulmonary oedema
• Cardiovascular support addressing any haemodynamically significant patent ductus arteriosus (PDA)
• Anaemia treatment - regular blood transfusions in very preterm babies where low haemoglobin worsens oxygen delivery
• Infection prevention - RDS babies are highly vulnerable to secondary bacterial pneumonia
   

6. Prevention of Chronic Lung Disease (BPD)
    
   Bronchopulmonary dysplasia is the most significant long-term complication of RDS treatment:

• Minimising invasive ventilation duration - the most important modifiable risk factor for BPD development
• Vitamin A supplementation - evidence-based supplementation reducing BPD risk in very low birth weight babies
• Post-natal steroid use carefully restricted - used only for ventilator-dependent babies who fail all other weaning attempts, given adverse neurodevelopmental associations
• Pulmonary follow-up after NICU discharge - monitoring for reactive airway disease and supporting families in recognising any ongoing respiratory symptoms
