Mechanical ventilation in newborn infants.

Area of Science:

• Neonatal Medicine
• Pediatric Critical Care
• Respiratory Physiology

Background:

• Mechanical ventilation (MV) is a critical intervention for neonates with respiratory failure.
• Data on MV outcomes in developing countries, particularly for infants weighing >= 1500g, are limited.
• Understanding challenges and outcomes in resource-limited settings is crucial for improving neonatal care.

Purpose of the Study:

• To describe the experience and outcomes of mechanical ventilation in newborn infants with birth weight >= 1500g in a developing country.
• To identify indications, complications, and survival rates associated with MV in this population.
• To determine risk factors for poor outcomes in neonates requiring MV.

Main Methods:

• A retrospective review of 41 neonates (birth weight >= 1500g) treated with MV over 20 months.
• Intermittent positive pressure ventilation and continuous positive airway pressure via nasotracheal intubation were employed.
• Data collected included indications for MV, duration, complications, and survival rates.

Main Results:

• The overall survival rate was 43.9%.
• Common indications included respiratory distress syndrome (RDS), aspiration pneumonia, and apnea.
• Frequent complications were sepsis (26.8%), pulmonary hemorrhage (21.9%), and congestive heart failure (17.1%). Post-extubation atelectasis occurred in 29.6%.

Conclusions:

• Mechanical ventilation in this cohort of higher-birth-weight neonates in a developing country was associated with significant morbidity and mortality.
• Risk factors for poor outcomes included low birth weight (<2000g), prematurity, and delayed referral to the Neonatal Intensive Care Unit.
• Improvements in neonatal care and timely interventions are needed to enhance survival rates.
