Abstract

This cross-over quasi-experimental research design aimed to study the effect of a rubber nest mattress innovation on sleep quality and physiological change in preterm infants. Twenty-three preterm infants with 32-36 weeks of gestational age, admitted in the Neonatal Moderate Intensive Care Unit, Hat Yai Hospital, during October 2020-June 2021 were drawn using purposive sampling without replacement and allocated randomly into: pattern 1) sleep on the rubber nest mattress on day 1 and sleep on a cloth nest mattress on day 2, and pattern 2) sleep on a cloth nest mattress on day 1 and sleep on the rubber nest mattress on day 2. The experiment was begun at the same time of day. Sleep-wake behavior was recorded by video camera and the vital signs were recorded every 10 minutes from 5.00-6.00 p.m. The video tape was then interpreted for the sleep duration. The instruments for data collection were 1) demographic data record form, 2) sleepwake behaviors of premature infant assessment form, and 3) environment and preterm infant’s vital signs record form. The content validity of the tools was verified by experts. Inter-rater reliability of the sleep-wake behaviors assessment between the expert and the researcher, and also between the researcher and the research assistant were tested, yielding a percentage of agreement of 95.0% and 98.33%, respectively. The demographic data were analyzed using descriptive statistics. The mean of sleep-wake duration and vital signs of preterm infants were compared between when on the rubber nest mattress and when on a cloth nest mattress using paired t-test. The results revealed that 1. The mean score of total sleep duration and deep sleep duration of preterm infants were significantly longer while they were on the rubber nest mattress than while they were on a cloth nest mattress (t = -3.46, p < .05; t = -4.40, p < .05, respectively). The active sleep duration of preterm infants while they were on each type of nest mattress was not significantly different (t = -.46, p > .05) 2). The mean score of vital signs of preterm infants while they were on the rubber nest mattress and cloth nest mattress showed that 2.1 The mean score of body temperature of preterm infants while they were on each type of nest mattress was not significantly different (t = .97, p > .05) 2.2 The mean score of respiratory rate and heart rate while they were on the rubber nest mattress were significantly lower than while they were on a cloth nest mattress (t = 2.40, p < .05; t = 3.78, p < .05, respectively). 2.3 The mean score of oxygen saturation while they were on the rubber nest mattress was significantly higher than while they were on a cloth nest mattress (t = -4.56, p < .05) The results showed that the sleep quality of preterm infants who were put on the rubber nest mattress was improved, including having longer total sleep duration and deep sleep duration. Therefore, using rubber nest mattress in caring for preterm infants admitted in hospital is one method to help promote growth and development of preterm infants appropriately.
