INTRODUCTION: Kangaroo care (KC) has been thought of as an important intervention for improving the care of low birth weight infants; however, the physiological effect of KC is still controversial.
OBJECTIVE: The aim of this study was to investigate physiological responses during KC.
METHODS: Sixteen low birth weight (<1600 g) infants with gestational ages of 24 to 32 weeks were studied. Heart rate (HR), respiration rate, pulse oxygen saturation (SPo2), and regional cerebral oxygenation (rSo2) were obtained in 3 periods continuously: before, during, and after KC. Spectral analysis was performed. Total amplitude, the power of low-frequency (LF; 0.06–0.10 Hz) band, high-frequency (HF, 0.15–0.40 Hz) band, and the ratio of LF/HF were calculated. Three groups were compared by analysis of variance.
RESULTS: Significant differences were not observed during KC in terms of mean HR, SPo2, and rSo2. By amplitude, these parameters were significantly decreased during KC (P < .001) and increased after KC (P < .001). The power of LF or HF was either significantly decreased during KC in HR, SPo2, and rSo2 (P < .05); however, the ratio of LF/HF was increased during KC in HR, whereas the ratio was decreased in rSo2 (P < .05).
CONCLUSIONS: These results suggest that KC influences the stability of rSo2 as well as HR and SPo2. Discrete results in the LF/HF ratio of rSo2 may indicate that KC has different effects on rSo2 associated with cerebral function.
