Brief Summary:
The development of sucking behaviors in preterm infants is thought to reflect neurobehavioral maturation and organization. From a clinical perspective, the ability to feed depends upon a coordinated sucking, swallowing and breathing pattern. In preterm infants less than 32 weeks gestation, this ability is not usually effective enough to sustain full oral feeds. In the interim, infants are fed by gavage tube until they are mature enough to take milk directly from the breast or bottle (Pinelli, Symington, 2005). Non-nutritive sucking has been used during gavage feeding and in the transition from gavage to breast/bottle feeding. The rationale for this intervention is that non-nutritive sucking facilitates the development of sucking behavior and improves digestion of enteral feeds.

Observational Model: Cohort
Time Perspective: Prospective
Official Title: Randomized Control Trial Evaluating The Effect Of Patterned Oral Somatosensory Entrainment Stimulation Program (NTrainer System) On Suck Development and Feeding Performance of Preterm Infants Born Between 23 And 34 Weeks Gestational Age
Study Start Date : November 2007
Actual Primary Completion Date : November 2008
Actual Study Completion Date : November 2008

Control Group
Control group When neonates are considered ready for oral feedings these feedings will be started with the standard oral feeding protocol for the NICU but without the NTrainer stimulation regimen described previously.
NTrainer System
NTrainer Experimental Group When neonates are considered ready for oral feedings these feedings will be started simultaneously with the NTrainer therapy. Control and experimental interventions will not be initiated until the infant is in an optimal behavioral state, i.e., drowsy to quiet alert (NIDCAP state 3 or 4). Preterm infants in the experimental group will receive alternating 3-minute epochs of patterned oral somatosensory stimulation and null conditions using the NTrainer© during the tube (gavage) feeding session up to 4 times per day.

Primary Outcome Measures :
  1. The Non-Nutritive Suck SpatioTemporal Index (NNS STI) [ Time Frame: 28 days ]
  2. Transition-to-Oral Feed (TOF) [ Time Frame: 28 days ]
  3. Length-of-Stay (LOS) in the NICU [ Time Frame: 28 days ]

Secondary Outcome Measures :
  1. Growth velocity: Weight Gain (gms/kg/day) [ Time Frame: 28 days ]
  2. Growth velocity: Head Growth (cm/wk) [ Time Frame: 28 days ]
  3. Growth velocity: Length Growth (cm/wk) [ Time Frame: 28 days ]

Study Population
Preterm Infants Born Between 23 And 34 Weeks Gestational Age

Inclusion Criteria:

  • Estational age between 23 weeks and 0/7 days and 34 weeks as per the best estimate by the neonatologist.

Hemodynamically stable and off all vasopressors B. Tolerating 120 ml/kg/day of enteral feedings C. Respiratory rate <80 breaths per minute D. Alert and active neurologic exam appropriate for post-menstrual age E. No signs of sepsis or intolerance of gastric feedings

Exclusion Criteria:

  • Gestational age < 23 weeks or > 34 weeks
  • Any major congenital anomalies
  • Not ready for oral feedings
