Anorectal manometry in premature infants.
Journal of Pediatric Surgery
|October 1, 1979
Summary
Premature infants can have a normal anorectal reflex, as shown by pressure studies. This finding indicates that low birth weight and prematurity do not prevent a typical anorectal reflex development.
Area of Science:
- Pediatrics
- Gastroenterology
- Physiology
Background:
- Establishing normal physiological parameters in premature infants is crucial for assessing their development.
- Anorectal function is a key indicator of gastrointestinal health in neonates.
Purpose of the Study:
- To determine normal anorectal pressure parameters in premature infants.
- To assess the presence and characteristics of the anorectal reflex in this population.
Main Methods:
- Utilized an infusion manometric technique for anorectal pressure studies.
- Recruited twenty-eight unselected premature infants for the study.
- Obtained rectal and anal sphincter pressure readings.
Main Results:
- Satisfactory pressure readings were achieved in 27 out of 28 infants.
- A normal anorectal reflex was observed in all infants with adequate readings.
- The study established preliminary normal parameters for anorectal pressures in premature infants.
Conclusions:
- Prematurity and low birth weight do not preclude a normal anorectal reflex.
- The findings suggest that standard manometric techniques can reliably assess anorectal function in premature infants.
- Further research may refine these parameters and explore clinical implications.
