The Development of an Accurate Test Weighing Technique for Preterm and High-Risk Hospitalized Infants

Breastfeeding Medicine, 06/04/2012

Haase B et al. – The data from this study support the use of this test weighing technique as an accurate, objective assessment of the measurement of breastmilk intake after a breastfeeding session, thus allowing medical decisions regarding supplementation to be based on objective data rather than inaccurate clinical indices of the quality of infant feedings at the breast.

Methods

  • Test weights were performed on a sample of hospitalized high-risk infants with and without leads who were bottle- or nasogastric-fed.
  • Volume consumed was compared to weight gain to determine whether the developed technique was accurate.

Results

  • In each group, with or without leads, only one measure of actual intake versus test weight result was found outside the confidence limits (95%), and only one measure was found outside the clinically acceptable difference of ±5 g.
  • Correlation coefficient (r2) values of weight gain by test weight to volume of intake were 0.998 for infants without leads and 0.997 for infants with leads.
