Insights
Swallowing exercises significantly accelerate independent oral feeding in preterm infants by improving oral feeding skills. Sucking exercises showed no significant benefit. This intervention aids in faster maturation of feeding abilities.
Area of Science:
- Neonatal development
- Pediatric nutrition
- Clinical intervention studies
Background:
- Preterm infants often struggle with oral feeding, impacting their nutritional intake and development.
- Developing effective interventions to improve oral feeding skills (OFS) in preterm infants is crucial for their health outcomes.
Purpose of the Study:
- To investigate the efficacy of specific sucking and swallowing exercises in accelerating the attainment of independent oral feeding in preterm infants.
- To determine if these exercises lead to faster maturation of infants' oral feeding skills (OFS).
Main Methods:
- Randomized controlled trial involving very low birthweight infants assigned to control, sucking, or swallowing exercise groups.
- Sucking exercise involved pacifier use; swallowing exercise involved placing milk boluses on the tongue.
- Primary outcome: days to independent oral feeding. Secondary outcomes: overall transfer, proficiency, transfer rate, and OFS levels.
Main Results:
- The swallowing exercise group achieved independent oral feeding significantly faster (15 ± 2 days) compared to controls (21 ± 2 days; p = 0.019).
- The sucking exercise group showed no significant difference in time to independent feeding (19 ± 2 days) compared to controls.
- Infants in the swallowing group demonstrated more mature oral feeding skills (OFS) than controls.
Conclusions:
- Swallowing exercises are an effective intervention for facilitating independent oral feeding in preterm infants.
- Sucking exercises did not demonstrate efficacy in accelerating oral feeding attainment.
- The benefits of swallowing exercises likely stem from accelerated maturation of infants' oral feeding skills.
Aim:
Preterm infants have difficulty oral feeding. We hypothesized that a specific sucking and swallowing exercises vs. no intervention accelerate the attainment of independent oral feeding through a faster maturation of infants' oral feeding skills (OFS).
Methods:
Very low birthweight infants were randomized to a control, sucking and swallowing groups. Sucking consisted of active sucking on a pacifier, and swallowing of placing a milk bolus (0.05-0.2 mL) on the tongue where the bolus rests prior to entering the pharynx. Primary outcome was days from start to independent oral feeding (SOF-IOF). Secondary outcomes included overall transfer (OT, % volume taken/volume prescribed), proficiency (PRO, % volume taken at 5 min/volume prescribed), rate of transfer (RT, mL/min) over the entire feeding and infants' OFS levels. OFS levels were defined by PRO and RT.
Results:
Days from SOF to IOF vs controls (21 ± 2) were similar for the sucking group (19 ± 2) and shorter for the swallowing group (15 ± 2; p = 0.019). Only the latter infants demonstrated more mature OFS levels than controls.
Conclusion:
The swallowing exercise is an efficacious intervention in facilitating the attainment of independent oral feeding, but not the sucking exercise. We speculate that the swallowing benefit resulted from an accelerated maturation of infants' OFS levels.
