Venous air embolism in a child undergoing posterior fossa craniotomy: a case report
Insights
Venous air embolism is a serious risk during pediatric neurosurgery, potentially causing fatal complications. Prompt monitoring and treatment are crucial for patient recovery.
Area of Science:
- Pediatric Neurosurgery
- Anesthesiology
- Critical Care Medicine
Background:
- Venous air embolism (VAE) poses a significant risk in pediatric neurosurgery, particularly in the sitting position, with reported incidences up to 33%.
- Children are more vulnerable to VAE due to smaller circulating volumes and potential shunting through a patent foramen ovale or patent ductus arteriosus.
- VAE can lead to severe physiological disturbances and fatalities, necessitating heightened awareness and vigilance.
Observation:
- A case report details a six-year-old child experiencing four episodes of VAE during posterior fossa exploration.
- Initial VAE episodes were tolerated, but subsequent events led to clinical instability.
- 11 cc of air was retrieved via a right atrial catheter, with the patient making a full recovery.
Findings:
- The case highlights the physiological impact of VAE in pediatric patients.
- It underscores the potential for rapid deterioration and the critical nature of air volume in children.
- Successful management involved early detection and intervention through catheterization.
Implications:
- This report emphasizes the importance of continuous monitoring for VAE during high-risk pediatric neurosurgical procedures.
- It advocates for prompt recognition and management strategies to mitigate severe outcomes.
- The findings reinforce the need for specialized protocols in pediatric neuroanesthesia to address VAE risks.
Abstract:
The incidence of venous air embolism in children undergoing neurosurgical procedures in the sitting position may be as high as 33 per cent. It may be more serious in children because smaller total volumes of air can produce serious physiologic disturbances or fatalities, and the risk of systemic air embolism through a patent foramen ovale or patent ductus arteriosus may be greater than in adults. The case of a six-year-old child who sustained four separate episodes of air embolism while undergoing posterior fossa exploration is presented. Early episodes were well tolerated, but later episodes produced clinical instability. A total of 11 cc of air was recovered from an indwelling right atrial catheter, and the patient recovered uneventfully. This case report illustrates the physiologic changes produced by venous air embolism and reviews the importance of adequate monitoring techniques and early treatment.
