Influence of general anaesthesia on ano-rectal manometry in healthy children
Insights
Ano-rectal manometry is key for diagnosing Hirschsprung's disease. Performing this test under general anesthesia can yield more accurate results in uncooperative children.
Area of Science:
- Pediatric Gastroenterology
- Surgical Diagnostics
Background:
- Ano-rectal manometry is a crucial diagnostic tool for Hirschsprung's disease.
- Accurate results depend on a calm, cooperative child.
- General anesthesia may be necessary for uncooperative pediatric patients.
Purpose of the Study:
- To evaluate the impact of general anesthesia on ano-rectal manometry in healthy children.
- To compare internal and sphincter activity during awake and anesthetized states.
Main Methods:
- 15 healthy children underwent manometric recordings of internal and sphincter activity.
- Recordings were performed both while awake and under general anesthesia.
Main Results:
- Tonic activity at rest was significantly reduced under general anesthesia.
- Internal sphincter relaxations in response to rectal distension were less pronounced during anesthesia.
- Despite reduced relaxations, these responses were still recordable under anesthesia.
Conclusions:
- Ano-rectal manometry can be effectively performed under general anesthesia.
- General anesthesia offers an advantage for diagnosing Hirschsprung's disease in uncooperative children.
- This approach ensures more reliable diagnostic data when awake testing is not feasible.
Abstract:
According to several investigations ano-rectal manometry is a valuable diagnostic test of Hirschsprung's disease. In order to yield accurate results it requires a quiet, calm child who cooperates. In the few instances when this is not possible, general anaesthesia may be desirable. Manometric recordings of the internal and sphincter activity were therefore performed in 15 healthy children when awake and during general anaesthesia. The tonic activity at rest was significantly reduced during anaesthesia. Relaxations of the internal sphincter in response to rectal distension were recorded in all children both when awake and during anaesthesia. They were, however, significantly less pronounced during anaesthesia. These findings strongly suggest that ano-rectal manometry in the diagnosis of Hirschsprung's disease may be performed with advantage during general anaesthesia if the child does not cooperate when awake.
