Insights
Anesthetic management for Beckwith-Wiedemann syndrome requires careful attention to hypoglycemia and macroglossia. Monitoring glucose and preparing for airway challenges are crucial for safe surgical repair of cleft palate and macroglossia.
Area of Science:
- Pediatric Anesthesiology
- Medical Genetics
Background:
- Beckwith-Wiedemann syndrome (BWS) is a congenital overgrowth disorder.
- Key features include exomphalos, macroglossia, and hypoglycemia, posing unique anesthetic challenges.
Observation:
- Two pediatric cases undergoing cleft palate repair and macroglossia reduction highlight anesthetic considerations.
- Macroglossia can complicate airway management, including mask ventilation and intubation.
Findings:
- Hypoglycemia requires vigilant intraoperative plasma glucose monitoring to prevent neurological complications.
- Airway difficulties necessitate proactive strategies, such as awake vocal cord inspection before induction.
Implications:
- This case series emphasizes the importance of tailored anesthetic plans for BWS patients.
- Proactive management of hypoglycemia and airway issues ensures improved patient outcomes during surgery.
Abstract:
Anesthetic considerations of 21-mo-old and 4-yr-old sisters with Beckwith-Wiedemann syndrome during surgical repair of cleft palate and reduction of macroglossia are presented and discussed. This syndrome is characterized by exomphalos, macroglossia, gigantism, hypoglycemia in infancy, and many other clinical features. This syndrome is also known as exomphalos, macroglossia, and gigantism (EMG) syndrome. Principal problems associated with anesthetic management in this syndrome are hypoglycemia and macroglossia. Careful intraoperative plasma glucose monitoring is particularly important to prevent the neurologic sequelae of unrecognized hypoglycemia. It is expected that airway management would be complicated by the macroglossia, which might cause difficult bag/mask ventilation and endotracheal intubation following the induction of anesthesia and muscle paralysis, so preparations for airway difficulty (e.g., awake vocal cord inspection) should be considered before induction. A nasopharyngeal airway is useful in relieving postoperative airway obstruction.
