Effect of Swaddling on Sleep Period of Preterm Infants
Keywords:
Swaddle, Sleep duration, Standard nursing care, Preterm infantsAbstract
Preterm infants in the neonatal care unit receive excessive stimulation from the environment. This environment is different from the mother’s womb and affects sleep duration, the development of the central nervous system, and can lead to an abnormal sensory system in preterm infants. Fortunately, swaddling is a method that can be used to help preterm infants have longer sleep periods. The study aimed to compare the effects of swaddling and standard nursing care on the sleep states of preterm infants. Fourteen preterm infants postconceptional aged between 32-36 weeks admitted to neonatal care unit at Chiang Rai Prachanukroh Hospital were studied. The study used a one group cross-over experimental design. The control group received routine nursing care and the experiment group received the swaddle. The researcher observed and recorded by videotape the participant’s sleep and recorded the noise levels for a period of 2 hours. The researcher observed the sleep-wake states of preterm infants and recorded using Penjit Thanacharoenpipat’s methods and form (Thanacharoenpipat, 2001) . Environmental sound levels were also recored using Salisa Kodyee’s methods and form (Kodyee, 2015). The recorded data were analyzed using descriptive statistics as dependent sample t-test. Wilcoxon Matched Pairs Singed-Ranks Test was used for matched pairs. The study found that:
- The mean duration of total sleep in the group using the swaddle was statistically significantly greater than the control group receiving routine nursing care (p<.05)
- The mean duration of deep sleep in the group using the swaddle was statistically significantly greater than the control group receiving routine nursing care (p<.05)
The findings of this study indicated that swaddling can promote a longer duration of deep sleep and greater total sleep than routine nursing care. This study could be used as a guide for improving the duration of sleep in preterm infants.
