The effect of sensory stimulation on apnea of prematurity.

OBJECTIVES

The study aims to assess the effect of sensory stimulation on apnoea among premature newborns.

METHODS

Thirty preterm newborns that were diagnosed with apnoea of prematurity, had a gestational age between 32 and 34 weeks, had low birth weight, and were appropriate for gestational age from 1200 to 2000 g were included in this prospective randomized study. Subjects were divided into two equivalent groups: a control group that received the standard care including nasal oxygen (one litre per minute) and caffeine citrate, and a study group that received the same care plus sensory stimulation (tactile, proprioceptive, and kinaesthetic). Participants' heart rate, oxygen saturation, and apnoea frequency were measured by the neonatal intensive care unit team using a pulse-oximeter. The sensory stimulation sessions were 10 min, 3 times per day, totalling 30 min over a 7 day period.

RESULTS

There was a significant decrease in heart rate within both groups after receiving treatment from before treatment ( < 0.05), with no significant differences between the two groups. Furthermore, there was no significant difference in oxygen saturation within the groups after treatment compared with the levels before treatment, with no significant differences between the two groups ( > 0.05). Before treatment, there was a non-significant difference in the apnoea rate between both groups ( = 0.464), whereas there was a significant decrease in the apnoea rate of the study group after treatment compared with the control group ( = 0.031).

CONCLUSION

Sensory stimulation applied with standard respiratory care can decrease the frequency of apnoea of prematurity.
