Abstract
INTRODUCTION : Prematurity is defined as babies born alive before 37 weeks of gestation. Since preterm neonates offers less time of growth or development in the uterus of mother the internal organs are not matured fully. Due to this, it will take few more weeks to the preterm neonates in the NICU for further maturation of organs to lead a life without medical care .So the infant needs special care in the NICU until the organs have developed enough to keep the baby alive without medical support. This may take weeks to months. In the NICU preterm neonates are repeatedly subjected to painful, intrusive procedures develop touch aversion and exposed to noisy monitor sounds develop noise aversion. Gentle tactile and auditory stimulation reduce infant morbidity and mortality rates and helps to maintain the normal physiological parameters. The aim of the study was to evaluate the effect of tactile and auditory stimulation among preterm neonates and those who received it will experiences more significant weight gain, stable temperature, stable heart rate, stable respiratory rate, oxygen saturation, improved feeding pattern, increased sleeping time, decreased crying spells and increased urination compared to control group. OBJECTIVES : 1. To assess the pre and post intervention physiological parameters among experimental group of preterm neonates who had tactile & auditory stimulation 2. To assess the pre and post intervention physiological parameters among control group of preterm neonates 3. To evaluate the effectiveness of tactile & auditing stimulation on physiological parameters among preterm neonates. 4. To find out the association between the physiological parameters after tactile & auditory stimulation & selected demographic variables such as gestation weeks, age, sex, birth weight of the baby, APGAR score and mode of delivery. METHODOLOGY : A quantitative research approach with true experimental research design was adopted for this study. 120 preterm neonates who got admission and present in the NICU or postnatal unit of KKMCH, whose age is between 10 to 24 days, with 5 minute Apgar score of 6 or more, physically stable preterm babies with the birth weight of 1000 gram to 2000 gram were selected as study samples. Among them 60 preterm neonates were assigned in experimental group and 60 preterm neonates were assigned to control group randomly. Preterm neonates in experimental group received tactile stimulation by using coconut oil along with auditory stimulation in the form of lullaby by using Neelambari raga for 10 minutes twice a day for 5 consecutive days. The changes in physiological parameters were assessed before, during (3rd day) and after (5th day) the intervention period in both groups. The tool was developed, validated by experts and checked for its reliability (Physiological parameters: Weight: r = .705, Temperature: r = .658, Heart rate: r = .845, Respiratory rate: r = .736, Oxygen saturation: r = .622, Structured Interview Schedule: r = .746 and the internal consistency of the tool (r = 0.95)) before applied to collect data from samples. RESULTS : The results found that the preterm neonates, who received tactile and auditory stimulation achieved weight gain (t = 35.368), stable temperature (t = 55.865), stable heart rate (t = 40.948), stable respiratory rate (t = 41.078), stable oxygen saturation (t =43.937), increased feeding pattern (X2 = 26.612), increased sucking pattern (X2 = 30.572), increased duration per sleep (X2 = 43.364), increased sleeping pattern (X2 = 56.885), decreased crying pattern (X2 = 48.553) and increased urination pattern (X2 = 58.989) than control group preterm neonates. These results were statistically significant at 0.05 level. The present study findings concluded that the tactile and auditory stimulation had positive effects on growth and maturation in preemies. CONCLUSIONS : The following conclusions are drawn from the study: • The selected physiological parameters (weight, temperature, heart rate, respiratory rate, oxygen saturation, frequency of feeding per day, duration of sucking per feed, duration per sleep, duration of sleep per day, cries per day and passing urine per day) score in the experimental group was significantly improved after tactile and auditory stimulation than before tactile and auditory stimulation. • The selected physiological parameters (weight, temperature, heart rate, respiratory rate, oxygen saturation, frequency of feeding per day, duration of sucking per feed, duration per sleep, duration of sleep per day, cries per day and passing urine per day) score in the experimental group was higher than the post intervention physiological parameter score in the control group. • The findings of this studies suggest that music & massage interventions may have positive effects on preterm infants in the NICU including increased oxygen saturation levels, reduced heart rates, increased levels of quiet alert or quiet sleep states, improved parent-infant interaction, improved weight gain, and reduced length of hospitalization. • There is significant association between the weight gain and the selected demographic variables such as gestational age, age of the preterm neonates in the experimental group. Recommendations : Tactile and auditory stimulation can be used in any clinical and community settings to maintain the physiological parameters among preterm and term neonates.
