Area of Science:

  • Cardiology
  • Pediatric Surgery
  • High-Altitude Medicine

Background:

  • Patent ductus arteriosus (PDA) is a common congenital heart defect in children.
  • High-altitude environments present unique physiological challenges, including reduced oxygen availability.
  • Surgical interventions for congenital heart defects at high altitudes require careful consideration of patient acclimatization and anesthetic management.

Purpose of the Study:

  • To evaluate the safety and feasibility of surgical ligation of patent ductus arteriosus (PDA) in children residing at high altitudes.
  • To assess the outcomes of pediatric cardiac surgery performed during medical camps in remote high-altitude regions.

Main Methods:

  • Retrospective review of 11 pediatric patients (ages 4-17) who underwent PDA ligation.

  • Procedures performed at Sonam Norboo Memorial District Hospital in Leh, Ladakh (11,400 feet).
  • Surgery conducted under general anesthesia with endotracheal intubation, with same-day extubation.

    • Main Results:

    • All 11 children survived the PDA ligation procedure.
    • No surgical or anesthetic complications were reported.
    • Patients were discharged within 5-6 days post-surgery.
    • Children had low mean arterial oxygen saturation at room air but were acclimatized to high altitude.

    Conclusions:

    • Simple cardiac surgical procedures, like PDA ligation, can be performed safely and effectively at high altitudes.
    • High-altitude medical camps can successfully provide essential pediatric cardiac surgical care.
    • The study supports the feasibility of managing congenital heart defects in pediatric populations in remote, high-altitude settings.
