The heel test it’s a blood test routinely performed on newborns to diagnose rare diseases of genetic origin, such as phenylketonuria and congenital hypothyroidism. The puncture to extract the sample is not pleasant for babies.
Now, US researchers have found that listening to a nana de Mozart It can help reduce the pain that neonates experience from that heel stick. The study is published in the journal Pediatric Research.
The authors, led by researcher Saminathan Anbalagan from the Lincoln Medical & Mental Health Center in New York (USA), have carried out a randomized, blinded clinical trial in which they participated 100 infants of that city.
Data were collected between April 2019 and February 2020 from infants who were, on average, two days old and were born at 39 weeks gestational. 53% were male and 61% Hispanic. As part of standard care, all were given 0.5 milliliters of sugar solution two minutes before performing the heel stick.
Gestures and crying to measure pain
The researchers evaluated the pain levels based on babies’ facial expressions, degree of crying, breathing patterns, limb movements, and alertness levels.
To perform the experiment, 54 of the 100 infants heard the song crib instrumental music by Mozart for 20 minutes before, the very moment of the puncture and five minutes after, while the rest did not listen to music.
The mean pain score of the infants who listened to the lullaby was significantly lower during and immediately after the heel stick
The researchers had take into account the possible influence of other stimuli sensory on pain levels by routinely performing the procedure in a quiet, dimly lit room at room temperature and not providing infants with pacifiers or physical comfort.
The authors observed similar pain levels in both groups of infants prior to heel stick, with mean pain scores of zero in both groups, setting a maximum possible score of seven.
However, the mean pain score of the infants who listened to the lullaby was significantly lower during and immediately after the heel stick, compared to those who did not listen to music.
less pain with music
The pain values of the infants who listened to the lullaby were four during heel stick, zero one minute after procedure and zero two minutes after heel prick.
For their part, the pain scores of those who did not listen to the lullaby were seven, 5.5 and two at the same moments.
The investigators no longer observed significant differences in the mean pain values of the infants in both groups three minutes after the procedure.
Recorded music may be effective in relieving pain in newborns undergoing minor procedures
The results suggest that recorded music may be a effective method of relief of pain in newborns undergoing minor procedures.
The authors suggest that future investigations study whether the recordings of the parent voices may also reduce pain in newborns during minor procedures, as well as explore the influence of physical comfort of caregiversin addition to music, on pain levels.
