The objective of this study is determining if enteral administration of Lactated Ringer's solution (LR) in preterm infants with feeding intolerance enables for faster advancement of milk feeding than fasting.

Primary Outcome Measures:
  • Average of the daily enteral caloric intake (in calories/kg/day) received over the 14 days after study entry [ Time Frame: 14 days ]
    To measure enteral caloric intake, the volume of milk feeding, for each patient will be recorded daily and for 14 days. Unfortified milk and fortified milk are calculated as containing respectively 0.67 Cal/ml and 0.81 Cal/ml.

Secondary Outcome Measures:
  • Number of days to reach 130 ml/kg milk feeding [ Time Frame: variable ]
  • Number of days to discontinue IV access [ Time Frame: variable ]
  • Growth (weight, height, head circumference), increase % after 14 days and between study entry and discharge home [ Time Frame: variable ]
  • Length of hospitalization [ Time Frame: variable ]
  • Necrotizing enterocolitis [ Time Frame: during the 14 day-study period and hospitalization ]
  • Electrolytes, bilirubin, serum urea nitrogen, creatinine and liver enzymes [ Time Frame: 14 days ]
  • Infections [ Time Frame: until discharge ]

Estimated Enrollment: 60
Study Start Date: November 2010
Estimated Study Completion Date: September 2012
Estimated Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Fasting
Active Comparator: Lactated Ringer's Solution Drug: Lactated Ringer's Solution
2.5 ml per kg every 3 hours, via nasogastric tube, orogastric tube or orally, until the infant reaches 80 ml/kg/day of milk feeding or for a maximum of 14 days
Other Name: Lactated Ringer's

Detailed Description:

Feeding intolerance is a common problem in premature infants in the Neonatal Intensive Care Unit. Definition is clinical and based on abdominal distension, abdominal tenderness, emesis, change in gastric residuals, presence of blood in stool, and apnea with bradycardia.

Feeding intolerance is associated with serious complications: necrotizing enterocolitis, longer hospitalization and prolonged intravenous nutrition complications (e.g. sepsis, liver damage). Therefore, the investigators aim to achieve adequate enteral nutrition as soon as possible.

Because LR is a an amniotic fluid-like solution, it may improve gastro-intestinal function and avoid fasting, as well as its multiple problems (e.g. intestinal atrophy and decreased intestinal motility). LR was chosen as the test solution because of experience documenting its safe use in comparable groups: in newborn resuscitation parenterally, in amnioinfusion, and in bowel irrigation. Moreover, LR is similar in electrolytes composition to the experimental solution used in previous studies by Barney et al in neonates.

Inclusion Criteria:

  • Birth gestational age (GA) between 25 and 32 weeks
  • Corrected gestational age less than 34 weeks
  • Enteral feeding tolerated at a minimum of 10 ml/kg/day for a minimum of 48 hours
  • Severe feeding intolerance, defined as a minimum of one or more of the following signs leading to withholding of milk feedings on two evaluations over 12 to 24 hours:

    1. Significant increased abdominal girth, as evaluated by the treatment team, with abdominal tenderness
    2. Visible enlarged bowel loops with abdominal tenderness
    3. Recurrent emesis leading to withhold feeds
    4. Gastric residuals in excess of one feeding, recurrent or with growing abdominal girth
    5. Visible blood in stools without anal etiology
