[Procedural pain perception of preterm newborn in neonatal intensive care unit: assessment and non-pharmacological...

The aim of this study was to evaluate the reaction to the procedural pain of preterm newborn and to demonstrate the different effectiveness of the two analgesic and not pharmacological techniques of recent clinical acquisition, the use of glucose solution and the sensorial saturation, in order to identify an optimal strategy for the prevention and pain treatment.

We take a sample of 28 preterm newborns of 30-35 weeks. The subjects are divided in two randomized groups following the kind of analgesia used during the hematic sample from heel: the first group (group A) included 14 subjects, who received glucose solution associated to no nutritive suction; the second group (group B) included 14 subjects who received the sensorial saturation. The symptoms associated with pain at the moment of venous sample are measured through premature infant pain profile (PIPP) scale.

Results show that the score was lower in the group treated with sensorial saturation (media 6.52; P<0.001) than in the group treated with glucose (media 13.80; P<0.05).

The use of "care" techniques (in our case sensorial saturation) ameliorates the quality of life in NICU and reduces the pain threshold perceived by newborn, reducing therefore the exposition to the pain stimulus and the possibility that some consequences due to an inadequate pain treatment in neonatal age could develop.
