Abstract
To verify the nutritive and non-nutritive stimuli efficacy in the newborn's response to pain during venipuncture. The main sample was composed of 64 newborns that were randomly divided into three groups. The first group (n=20) received nutritive sucking stimulus that was performed through maternal breastfeeding. The second group (n=21) received non-nutritive sucking stimulus that was performed through the introduction of the researcher little finger in the newborn's oral cavity. The third group or control group (n=23) did not receive any analgesia stimulus. The newborns were evaluated using the Neonatal Infant Pain Scale, and the responses to painful stimuli were compared. The nutritive as well as non-nutritive suction methods provided a comforting effect, resulting in lower pain response scores (p<0.05). There was no difference between the analgesia provided by both methods (p>0.05). The nutritive and the non-nutritive sucking stimuli proved to be efficacious tools in relieving pain among newborns.
Highlights
Pain can be defined as an unpleasant sensorial and emotional experience associated with a real or potential injury to the body tissues[1]
It is a subjective sensation, and it is through painful experiences that occur from birth that each individual learns its meaning[1]
The present study aimed to investigate the analgesic potential of the nutritive sucking (NS) and non-nutritive sucking (NNS) stimuli among newborns undergoing venipuncture
Summary
Pain can be defined as an unpleasant sensorial and emotional experience associated with a real or potential injury to the body tissues[1]. It is a subjective sensation, and it is through painful experiences that occur from birth that each individual learns its meaning[1]. A newborn modifies his physiological, behavioral, and psychological parameters during an acute painful stimulus in order to stop or limit the duration of the painful experience[1] This process requires great energy expenditure, leading to the increase of heart rate, blood pressure, the respiratory rate variability, and behavioral modifications, such as crying and specific facial expressions[3]. The importance of checking the efficacy of both methods remains in the fact that it could be used in the hospital and ambulatorial clinical practice in a routine basis, requiring no additional costs, in order to provide pain relief in pursuit of improvements in a newborns’ care and their quality of life
