Comparison of 25% Dextrose versus Expressed Breast Milk in Reducing Pain while Heel Prick Procedure in Preterm Neonates in a Tertiary Care Hospital, Vadodara, Gujarat, India: A Randomised Clinical Trial

Introduction: Preterm infants undergo repeated painful procedures during a period of rapid brain development and programming of stress systems. Newborn babies including preterm infants do feel pain. Although different interventions, such as skin-to-skin contact, glucose solutions, breastfeeding, and local anaesthetic agents, have been evaluated to reduce infants’ pain, there is no clinical trial available to identify the best method. Aim: To compare the dectrose 25% versus Expressed Breast Milk (EBM) in reducing pain while heel prick procedure in preterm neonates in a tertiary care hospital. Materials and Methods: The present randomised clinical trial was conducted at Neonatal Intensive Care Unit (NICU) of Kashiben Gordhandas Patel Children Hospital, Vadodara, Gujarat, India, from September 2019 to May 2020. Total 125 neonates with Gestational age between 28 weeks to 36 weeks were included in the study. Babies were divided into two groups by randomisation: Group-A: EBM and Group-B: Dextrose 25%. Premature Infant Pain Profile (PIPP) score was calculated from worst state of individual recovery period (0-½ minute, 1-1½ minute, 3-3½ minute) and compared to baseline period PIPP. Results: Mean gestational age on examination in Group-A was 34.48±6.14 weeks and in Group-B were 34.51±5.89 weeks. Out of total 125 preterm babies (Group-A-62, group B-63), 71 (56.8%) were male and 54 (43.2 %) were females. Comparison of PIPP at 1-1½ min of heel prick in EBM and Dextrose 25% group was statistically significant (p-value <0.003) suggestive of continued analgesic effect of dextrose 25% better than EBM and PIPP scores after 3-3½ min of heel prick having no statistically significant difference. (p>0.05) Mean difference between the PIPP score in the dextrose 25% and EBM groups was -1.25 and -1.33 at 0 and 1 minute after procedure (p-value,
