Insights
Pneumothorax is a rare complication in pediatric laparoscopic surgery. This case report details a 7-month-old infant who developed pneumothorax during antireflux surgery, highlighting the need for vigilance.
Area of Science:
- Pediatric Surgery
- Anesthesiology
- Thoracic Surgery
Background:
- Pneumothorax is a known complication of laparoscopic surgery.
- Reports in the pediatric population are infrequent.
- Laparoscopic procedures in infants require careful monitoring.
Observation:
- A 7-month-old girl developed sudden intra-abdominal hypertension (>30 mmHg) and hypoxemia (SpO2 <80%) during laparoscopic gastroesophageal antireflux surgery.
- This occurred despite a low insufflation pressure (6 mmHg) and standard anesthetic management.
- A pleural injury and pneumothorax were identified as the cause.
Findings:
- The infant experienced a sudden increase in intra-abdominal pressure and a significant drop in oxygen saturation during laparoscopic surgery.
- A diaphragmatic injury leading to pneumothorax was diagnosed and surgically repaired.
- The patient recovered fully with resolution of pneumothorax post-operatively.
Implications:
- This case underscores the risk of pneumothorax in pediatric laparoscopic surgery, even with low insufflation pressures.
- It highlights the importance of recognizing and managing sudden intra-abdominal hypertension and hypoxemia during these procedures.
- Prompt diagnosis and repair of diaphragmatic injuries are crucial for favorable outcomes in pediatric patients.
Abstract:
Pneumothorax is a complication associated with laparoscopic surgery, but there have been few reports of this complication in the pediatric population. We experienced a case of 7-month-old girl who developed pneumothorax during laparoscopic gastroesophageal antireflux surgery. After induction of general anesthesia, the trachea was intubated with a 3.5 mm internal diameter tube without a cuff. Anesthesia was maintained with sevoflurane and intermittent bolus injections of fentanyl. The insufflation pressure of carbon dioxide was 6 mmHg. Approximately 2 hours after the start of surgery, the intra-abdominal pressure suddenly increased to above 30 mmHg followed by a decrease in Sp(O2) to below 80%. We increased FI(O2) to 1.0 and ventilated lungs by bag. Sp(O2) recovered to 98%, but the Et(CO2) increased above 50 mmHg. Fifteen minutes after the episode, the pleural injury was found. The injured diaphragm was then repaired, and the trachea was extubated after surgery uneventfully. The pneumothorax resolved on the next day.
