title: Effect of Erythromycin on Gastric Emptying Time of Low Birth Weight Babies.
abstract: BACKGROUND
  To study the promotility effects of low dose erythromycin on gastric emptying time in a population of normal low birth weight (LBW) neonates on breast feeds with or without nutritional supplements and human milk fortifier (HMF).
  
  
  METHODS
  A randomised control trial involving 50 neonates was undertaken and they were given 6mg/kg/day of oral erythromycin or placebo in three divided doses for four consecutive days in the first two weeks of life. The gastric emptying time (GET) was assessed ultrasonographically by measuring the decrease in the antral cross sectional area (ACSA). The time taken for the ACSA to become half the prefeed value, was taken as t/2 or half GET. The babies were also assessed for pre and post intervention side effects of the drug. The results were analysed using SPSS ver 11.5.
  
  
  RESULTS
  The test group showed a significant decrease in GET after the intervention. This effect was mainly seen in the preterm babies as compared to term Small for Gestational Age (SGA) babies. The decrease in GET was more in babies born after 34 weeks of gestation as compared to smaller babies. The reduction in GET was seen in babies on breast milk alone and nutritional supplements with breast milk but not when HMF was added. No side effects of the drug were noted.
  
  
  CONCLUSIONS
  Low dose erythromycin is a safe way of decreasing gastric emptying in preterm babies born after 34 weeks of gestation in the first two weeks of life.
