ABSTRACT
Previous randomized trials of the analgesic effects of sucrose, glucose, and a pacifier in term neonates have shown that the pacifier resulted in lower pain scores than glucose or sucrose, but the pacifier with and without sucrose did not differ. The current study was designed to assess the analgesic effect of pharmacologic [sucrose, water] and a non-pharmacologic measures [pacifier] in preterm infants and to find whether there is any synergism between these intervention in relieving pain during painful procedures. In this double-blind, randomized, controlled study, 36 preterm infants [mean 31 weeks gestational age, range 27 to 36 weeks] were randomly allocated to six different regimens [0.5 mL sterile water with pacifier, 0.5 mL sterile water without pacifier, 0.5 mL sucrose 24% with pacifier, 0.5 mL sucrose 24% without pacifier, pacifier alone and control group] during a stay in intensive care of up to 15 days. Pain scores were measured with the Premature Infant Pain Profile [PIPP], a validated behavioral acute pain scale. Of all the regimens, the lowest pain scores occurred with the use of 24% sucrose solution combined with pacifier. The mean pain score for the combination of sucrose with pacifier was 0.7 as compared to 1.4 for the sterile water with pacifier group [P < .05]. The synergistic effect of the combination of sucrose and non-nutritive sucking was clinically effective and safe in relieving the pain of simple procedures such as venipuncture or heel stick in preterm and term infants, but further research is needed on these interventions alone and in combination with other behav-ioral interventions in neonates
