Comparison the Effect of Mother's Milk Odor and Vanilla on Response to Pain in Venous Puncture in Control Randomized Clinical Trial Preterm Newborn.

Abstract

Abstract: Introduction: Research suggests that both preterm and term infants can be remember, understand and prefer intrauterine and environmental odors. Use of olfactory stimuli during painful medical procedures reduces pain responses of infants. The main purpose in preterm infants during and after venipuncture. Methods: This study is a randomized clinical trial research. 135 preterm infants who were eligible to participate in the study were randomly selected and divided into three groups, breast milk, vanilla and control. Results: In breast milk group, infants were exposed to the smell of breast milk odor five minutes before sampling to thirty seconds after it finishes. In vanilla group, infants were exposed to the smell of vanilla odor. PIPP tool is used to measure pain associated with blood sampling. PIPP score were calculated for infants of both of groups thirty seconds before venipuncture, during sampling and 30 seconds after the end of sampling. Statistical analyses, which were performed on the results, indicate that there are significant difference between pain score of infants of control and breast milk groups during sampling (p=0.01). Study shows that breast milk odor causes to reduction of preterm infants' response to pain during and after blood sampling.
