Effect of music combined with swaddling on pain in full-term newborns: randomized clinical trial.

OBJECTIVES

to evaluate the effect of music applied within ten and 15 minutes, combined with swaddling, on behavioral (facial action) and physiological (heart rate) responses to pain in full-term newborns, before and during venipuncture for blood sampling.

METHODS

a randomized, triple-blind, clinical trial with 52 rooming in infants randomly assigned to four groups of 13: Experimental 1 (music [ten minutes] plus swaddling), Experimental 2 (music [15 minutes] plus swaddling), Control 1 (no music [ten minutes] plus swaddling), and Control 2 (no music [15 minutes] plus swaddling). Pain was measured using the Neonatal Facial Coding System in the basal and procedural moments.

RESULTS

experimental 2 group showed high pain absence (p < 0.05); low heart rate mean (p < 0.0001) in the basal and procedural (antisepsis, puncture, blood squeezing/aspiration, compression) moments.

CONCLUSIONS

neonates who listened to 15 minutes of music plus swaddling showed a greater absence of facial pain actions.
