Gouin S, et al. - In this study, researchers performed comparison of the efficacy of an oral sucrose solution vs. a placebo in reducing pain in infants undergoing venipuncture without cannulation. The administration of an oral sweet solution did not statistically decrease pain scores in infants 1 to 3 months of age undergoing simple venipuncture. They observed no significant change in participants' heart rate variations and crying time with the administration of this solution.
