Persistent Pulmonary Hypertension of the Newborn (PPHN)

Overview

Persistent Pulmonary Hypertension of the Newborn (PPHN) is a serious neonatal condition in which a newborn’s circulatory system does not adapt properly after birth, resulting in high blood pressure in the lungs. This prevents adequate oxygen from entering the bloodstream.

Normally, after birth, blood flow to the lungs increases to allow oxygen exchange. In PPHN, the blood vessels in the lungs remain constricted, limiting oxygen delivery to the body.

At Moolchand Hospital, newborns with respiratory complications receive specialized treatment in the Neonatal Intensive Care Unit (NICU) under the care of experienced neonatologists and pediatric specialists. As a trusted multi super speciality hospital in Delhi and a leading hospital in Lajpat Nagar Delhi, Moolchand provides advanced neonatal monitoring and treatment for critical newborn conditions.

What is Persistent Pulmonary Hypertension?

In the womb, a fetus receives oxygen through the placenta rather than the lungs. Because of this, most blood bypasses the lungs before birth.

After delivery, the newborn’s lungs begin functioning, and blood vessels in the lungs normally relax to allow proper blood flow.

In PPHN, these blood vessels remain abnormally narrow, causing:

• Reduced blood flow to the lungs
  
  

• Low oxygen levels in the blood
  
  

• Increased strain on the heart
  
  

This condition requires urgent medical care.

Symptoms

Symptoms of PPHN typically appear soon after birth.

Common symptoms include:

• Rapid or difficult breathing
  
  

• Bluish discoloration of skin or lips (cyanosis)
  
  

• Low oxygen levels despite oxygen therapy
  
  

• Rapid heart rate
  
  

• Chest retractions during breathing
  
  

• Poor feeding or lethargy
  
  

Severe cases may require immediate respiratory support.

Causes

PPHN may develop due to conditions that affect lung function or blood flow in newborns.

Common causes include:

• Meconium Aspiration Syndrome
  
  

• Perinatal Asphyxia
  
  

• Pneumonia or infection in newborns
  
  

• Congenital diaphragmatic hernia
  
  

• Premature birth
  
  

• Lung development abnormalities
  
  

These conditions may interfere with normal adaptation of lung circulation after birth.

Risk Factors

Certain factors increase the risk of persistent pulmonary hypertension in newborns:

• Premature birth
  
  

• Maternal diabetes or hypertension
  
  

• Post-term pregnancy
  
  

• Complicated labor or delivery
  
  

• Cesarean delivery without labor
  
  

• Congenital lung disorders
  
  

Careful monitoring during pregnancy and delivery can help reduce risks.

Diagnosis

Doctors diagnose PPHN using clinical evaluation and specialized tests.

Diagnostic procedures may include:

• Measurement of oxygen levels in the blood
  
  

• Chest X-ray to assess lung condition
  
  

• Echocardiography to evaluate heart and pulmonary circulation
  
  

• Blood gas analysis
  
  

• Continuous monitoring in the NICU
  
  

At Moolchand Hospital Delhi, advanced neonatal imaging and monitoring systems allow rapid diagnosis and treatment.

Treatment

Treatment focuses on improving oxygen levels and reducing pressure in the lung blood vessels.

Oxygen Therapy

High levels of oxygen help improve oxygenation in the bloodstream.

Mechanical Ventilation

Breathing support may be required in severe cases.

Inhaled Nitric Oxide

This therapy helps relax pulmonary blood vessels and improve blood flow to the lungs.

Medications

Medications may be used to support heart function and stabilize circulation.

Advanced Life Support

In severe cases, advanced life-support techniques may be used in specialized neonatal centers.

Early treatment significantly improves survival and recovery.

Possible Complications

If untreated or severe, PPHN may lead to complications such as:

• Severe oxygen deprivation
  
  

• Heart strain or heart failure
  
  

• Brain injury due to low oxygen
  
  

• Developmental delays
  
  

• Chronic lung problems
  
  

Prompt NICU care helps reduce these risks.

Prevention

Although PPHN cannot always be prevented, certain measures may reduce risk:

• Regular prenatal check-ups
  
  

• Proper management of high-risk pregnancies
  
  

• Monitoring fetal health during labor
  
  

• Early treatment of neonatal respiratory problems
  
  

Access to advanced neonatal care greatly improves outcomes.
