Neonatal painful stimuli: skin conductance algesimeter index to measure efficacy 24% of sucrose oral solution.

Pain management is one of the main challenges in addressing the improved care of hospitalized newborns. The administration of oral sucrose with and without non-nutritive suction has been proposed as a nonpharmacological intervention to relieve procedural pain in newborns. The effects have not yet been well characterized. The aim of this study is to investigate, using skin conductance algesimeter (SCA) pain monitor index, the effects of 24% sucrose solution on pain perception during capillary and arterial blood sampling. It is a prospective, randomized controlled study: sucrose versus placebo. Sucrose was given orally to infants who were submitted to arterial or capillary sampling. The SCA was measured during, and for 3 min before and after the intervention. Fifty-six infants were enrolled: 31 in the sucrose group and 25 in the placebo group. SCA showed that the measurement of peaks per second of pain during and 3 min after the procedures was lower in the sucrose group than the placebo group and that this difference was statistically significant ( p  < .05). In conclusion, 24% sucrose administered orally is effective in reducing pain during and after capillary and arterial sampling in newborns and can be used for the prevention and treatment of pain in the Neonatal Intensive Care Unit. Brief rationale To treat neonatal pain, a tiered approach with nonpharmacological and pharmacological method can be used.Among nonpharmacological therapies, sucrose administration is safe and effective in reducing single episodes of minor procedural pain. This study aimed to investigate, the effects of 24% sucrose solution on pain perception during capillary and arterial blood withdrawn by using an objective method: skin conductance algesimeter (SCA) pain monitor index.This randomized controlled trial in which term and/or preterm neonates (postnatal age maximum of 28 days corrected for postmenstrual age) received sucrose for procedural pain. Oral sucrose was administered directly by a disposable plastic vial. SCA was measured by means of a specific device.We demonstrated, using SCA pain monitor index, the efficacy of 24% sucrose solution on pain perception during capillary and arterial blood withdrawn. The results of this study provide an objective evidence of sucrose efficacy for the prevention and treatment of neonatal painful procedures.
