    Abstract:
    PDA (patent ductus arteriosus) is a common congenital heart disease. Usually surgical intervention through left thoracotomy or recently through video assisted thoracoscopy will be recommended if the preceding or intent medical treatment fails or is contraindicated. However, once surgical intervention is decided, various complications are still a real fear in the mind of the surgeon and the anesthesiologist, particularly if the infant is premature or very sick. Here we report an anesthetic management in a female preterm infant weighing 500 grams, who underwent PDA ligation. She was born at gestation age of 28 weeks at our hospital, and since her birth she was noted to have infant respiratory distress syndrome associated with renal dysfunction. She was admitted to the neonatal intensive care unit (NICU) straightaway. After thorough examination, a severe PDA was disclosed. The possibility of pulmonary hemorrhage and heart failure could be predicted in view of the large left to right shunt. Worst of all was that her poor renal function contradicted a medical treatment. So we decided to carry out the ligation procedure at once although she was premature and only 5 days old. The NICU was chosen as the operation theater for transferring concerns. General anesthesia was induced and maintained by atropine 0.01 mg, pancuronium 0.1 mg, fentanyl 2 micrograms, and ketamine 0.15 mg intravenously. Supplemental oxygen was given throughout the operation. The PDA was ligated through left thoracotomy and blood loss was minimal. The peri-operative course was uneventful. The patient recovered well following surgery and anesthesia.
