Introduction:

Wet lung, also known as transient tachypnea of the newborn (TTN), is a respiratory disorder primarily seen in newborns. This condition occurs when fluid in the infant's lungs is not adequately cleared during or after birth, leading to breathing difficulties. It's most common in babies born by cesarean section or delivered before full-term. This article provides a comprehensive overview of wet lung, including its causes, symptoms, diagnosis, treatment, and prognosis.

Causes of Wet Lung:

• Fluid Retention: During gestation, the baby's lungs are filled with fluid. Normally, this fluid is cleared during and after birth. In wet lung, the fluid clearance is delayed.
• Cesarean Delivery: Higher incidence in babies born via C-section, as the natural compression of the chest during vaginal delivery helps expel lung fluid.
• Premature Birth: Premature infants may have underdeveloped lungs and weaker respiratory muscles.

Symptoms of Wet Lung:

• Rapid Breathing (Tachypnea): Breathing rate over 60 breaths per minute.
• Grunting Sounds: Made by the baby while exhaling, as an attempt to keep air in the lungs.
• Nasal Flaring: Widening of the nostrils with each breath.
• Retractions: Indrawing of the chest wall, especially around the ribs, during breathing.

Diagnosis of Wet Lung:

• Clinical Assessment: Based on the newborn's breathing pattern and symptoms.
• Chest X-ray: May show fluid in the lungs or other signs consistent with TTN.
• Blood Tests: To rule out infections or other conditions.

Treatment of Wet Lung:

• Oxygen Therapy: To maintain adequate oxygen levels in the blood.
• Fluid Management: Ensuring the baby receives enough fluids, often intravenously.
• Monitoring: Close observation in a neonatal intensive care unit (NICU) may be necessary.
• Supportive Care: Feeding support and ensuring the baby stays warm and comfortable.

Prognosis and Recovery:

• Rapid Improvement: Most infants with wet lung show significant improvement within 24 to 48 hours.
• Full Recovery: Complete recovery is typically expected without long-term complications.
• Follow-up: Regular pediatric check-ups to monitor lung development and overall health.

Prevention and Awareness:

• Antenatal Care: Regular prenatal visits to monitor the baby’s development.
• Awareness of Risk Factors: Understanding the risks associated with cesarean delivery and premature birth.

Conclusion:

Wet lung is a relatively common condition in newborns, particularly those born via cesarean section or prematurely. Prompt recognition and appropriate medical intervention typically lead to a quick and full recovery. Understanding the causes, symptoms, and treatment options is crucial for caregivers and healthcare providers to ensure the best outcomes for affected infants.
