Psychophysiologic and behavioral effects of tactile stimulation on infants with congenital heart disease
1School of Nursing, University of California, San Francisco 94143.
Insights
Intense touch significantly increased arousal in infants with congenital heart disease, with girls showing greater physiological response. Some infants experienced distress from highly arousing stimuli.
Area of Science:
- Developmental Psychology
- Pediatric Nursing
- Infant Physiology
Background:
- Infants hospitalized with congenital heart disease require careful management of their physiological state.
- Understanding infant responses to sensory stimuli is crucial for optimizing care and minimizing distress.
Purpose of the Study:
- To investigate the impact of different verbal and tactile stimuli on arousal levels in infants with congenital heart disease.
- To examine gender differences in response to these stimuli.
Main Methods:
- A within-subjects, counterbalanced, repeated measures design was used with 24 infants.
- Physiological measures (heart rate, blood pressure, respiration) and activity level were recorded.
- Infants received six types of verbal and tactile stimuli.
Main Results:
- Intense, vigorous tactile stimulation of highly innervated areas significantly increased heart rate, systolic blood pressure, and activity levels.
- Girls exhibited greater physiological responsiveness to touch compared to boys.
- A subset of infants displayed distress during more arousing stimulation.
Conclusions:
- Specific types of tactile stimulation can significantly impact infant arousal and physiological responses.
- Gender may influence how infants with congenital heart disease respond to tactile input.
- Caregivers should be mindful of stimulus intensity to prevent potential infant distress.
Abstract:
A within-subjects, counterbalanced, repeated measures design was employed to determine the effects of gender and six different types of verbal and tactile stimuli on the arousal of 24 infants hospitalized for congenital heart disease during their first 6 months of life. Infants were systematically assigned to different sequences of the various stimuli. Measures of arousal included heart rate, blood pressure, respiration, and activity level. Results indicated that the use of touch conducive to neural excitation (i.e., intense, vigorous, extensive touching of highly innervated body areas) produced higher heart rates (p less than .01) and systolic blood pressure (p less than .002) as well as greater activity (p less than .01) than did other types of tactile stimulation or soothing verbal stimulation. Girls appeared more physiologically responsive to touch than boys and a subset of infants showed evidence of distress during more arousing stimulation.
