The effects of white noise and swaddling methods on orogastric tube insertion-related pain in preterm infants: A randomized controlled trial.

Aim: This study aims to investigate the effects of the white noise, swaddling and white noise + swaddling methods on pain and physiological parameters associated with orogastric tube insertion procedure.

Methods: This was a randomized controlled trial. A total of 132 preterm infants were randomly assigned to four groups as white noise group (n = 33), swaddling group (n = 33), white noise + swaddling group (n = 33) and control group (n = 33).
