Aim: To determine the effect of kangaroo mother care (KMC) on perfusion index, heart rate, and oxygen saturation in premature infants who were discharged early and admitted to the neonatal intensive care unit (NICU) in the following days.
Methods: This study has a randomized controlled experimental design and uses a pretest–posttest control group model. This study included infants between December 2019 and December 2020 who were discharged early and subsequently admitted to the NICU. Experimental (n=38) and control (n=38) groups were assigned using the simple randomization technique at the NICU of a private university hospital in Istanbul, Türkiye. Heart rate, perfusion index, and oxygen saturation levels of the experimental group in which KMC was applied and the control group in which KMC was not applied were compared. Measurements of these parameters were made at 15-minute intervals for 45 minutes (0–1, 15, 30, 45 minutes). Data were collected via the Mother and Infant Introductory Information Form, Kangaroo Mother Care Preparation Checklist, Kangaroo Mother Care Physiological Parameter Monitoring Form, and Noninvaziv Pulse Co-Oximetry. Statistics of these data were performed with the independent sample t-test, Pearson’s Chi-square, Fisher’s exact test.
Results: In the experimental and control groups, infants’ gestational age (31.11 ± 3.25 and 31.61 ± 3.04, respectively; p = .491) and weight (1778.29 ± 436.93 and 1953.29 ± 345.74, respectively; p = .057) were similar, and the differences were statistically insignificant. Before KMC, there was no difference between the heart rate, oxygen saturation, and perfusion index values of the experimental and control groups (p > .05). From the first 15 minutes after the application of KMC to 45 minutes post-KMC, there was a significant decrease in (p=0.001) and stabilization of heart rate and oxygen saturation in the experimental group compared with the control group. The heart rates in the experimental group at 15th, 30th, and 45th minutes during KMC were lower than in the control group (147.63 ± 11.04; 142.47 ± 11.94; 136.82 ± 13.22 and 153.13 ± 8.73; 154.50 ± 7.27; 154.84 ± 7.05, respectively). Also, their oxygen saturation during KMC was higher than in the control group (96.68 ± 2.08; 97.24 ± 2.18; 97.87 ± 1.66 and 94.79 ± 1.27; 94.66 ± 1.45; 94.39 ± 1.38, respectively). This significant difference between KMC on heart rate and oxygen saturation in the experimental group compared to the control group continued for 45 minutes after KMC. The perfusion index was significantly higher at 30 minutes and 45 minutes during KMC. However, although it continued after KMC, this change in perfusion index was not statistically significant.
Conclusion: Kangaroo mother care helps to regulate the heart rate, oxygen saturation, and perfusion index of premature infants who were discharged early and admitted to the NICU in the following days.
