BackgroundIncreasing comfort and physiological stabilization in preterm infants during neonatal care improves their neurophysiological development. Bathing procedures that support this development and will not expose the newborn to stress should be preferred.ObjectivesOur study aimed to examine the effectiveness of tub bathing and sponge bathing methods on the physiological parameters (i.e., heart rate, respiration rate, oxygen saturation, body temperature) and comfort of late preterm infants.DesignRandomized controlled trial. Study is registered at ClinicalTrials.gov NCT03796312.SettingsThe trial was conducted in a neonatal intensive care unit of a university hospital in Antalya, Turkey.MethodsLate preterm infants (gestational age between 34 0/7 weeks and 36 6/7 weeks) were randomly assigned by a computer program to either intervention (tub bath) or control group (sponge bath). The physiological parameters and comfort of preterm infants in both groups were evaluated at 10 min before the bath. Infant comfort was reevaluated 10 min after the procedure, while physiological parameters were reevaluated after 15 and 30 min. Preterm infant heart rate, oxygen saturation, respiratory rate, body temperature and comfort behaviors were assessed by two independent evaluators who were blinded to the purpose of the study at different phases across the two bathing protocols. Written consent was obtained from the university and hospital ethics committee where the research was performed, and from the families of the infants participating in the study. SPSS 20.0 and SAS 9.3 were used for data analysis. Data was analyzed by percentage distribution, mean, repeated analysis, variance analysis, Bonferroni analysis as a further analysis and t-test in dependent groups.ResultsApproximately 120 preterm infants completed the protocol (60 in each group). The two groups did not differ in gestational age, sex, weight or other demographic variables (p > 0.05). Tub bathing was more effective in reducing preterm infants' comfort scores (9.47 ± 2.55 vs. 14.85 ± 4.77, p < 0.001) and heart rate than sponge bathing (132.88 ± 12.00 vs. 144.00 ± 17.74, p < 0.05). Preterm infants in the tub bathing group maintained their body temperature better than those in the sponge bathing group (36.75 ± 0.26 vs. 36.59 ± 0.25, p < 0.05). There was no difference in oxygen saturation (98.35 ± 0.88 vs. 97.85 ± 1.36, p = 0.291) or respiratory rate (45.57 ± 5.39 vs. 47.20 ± 5.41, p = 0.472) between the tub and sponge bathing groups.ConclusionsTub bathing is a safer, more pleasurable/comfortable bathing option and is the recommended method for bathing healthy, late preterm infants.Copyright © 2019 Elsevier Ltd.
