Detailed Description
In infants undergoing respiratory support in NICU, it is important to determine the appropriate position, the frequency and duration of position change in order to reduce the oxygen need. Therefore, the aim of this randomized controlled study, test the efficacy of two different positions (prone-supine) given to preterm newborns receiving mechanical ventilation.The study was conducted from February 2015 to June 2016.
Participants and setting:
We were interested in establishing the difference between the supine position and the prone position, with an error margin of 10%. According to the formula of the calculated sample size, for a crossover design with a = 0.05, the sample size required to achieve a 90% power is 36 infants. Thirty-eight infants who met the inclusion criteria of the study were selected and invited to participate. Of these, parents of 38 infants consented. A convenience sample of hospitalized preterm infants (less than 37 weeks gestational age) was selected from a tertiary neonatal intensive care unit of a teaching and research hospital in Turkey. Preterm infants were divided into two groups by randomization according to position priority (n = 38). First group was first supine position followed by prone position (n = 19), second group was first prone position, then supine position (n = 19). The priority of the positions to be given to preterm infants was randomly determined using the closed envelope method. The positions of infants were written in envelopes and closed. The clinical nurse, who was not in the research, pulled the envelope and identified position group of the infant . Thus, data were collected for both the prone and the supine position from a newborn.
Procedure and data collection:
The infants involved in the study were cared for in a incubator and wore diapers only. The temperature of the incubator was set to maintain a body temperature ranging from 36.5 to 37.2 °C. After necessary routine procedures such as diapering, body cleaning, weighing and suctioning were completed, each subject was randomly assigned to the supine-prone group or prone-supine group sequence. All of the positions of preterm infants were given carefully by the researcher.
Data Collection Tools:
Infant descriptive characteristics form: The form was developed in light of the relevant literature to collect data about gender, age, gestational age, body weight at study.
Infant's clinical variables form. The form was developed by the researchers according to the literature to collect data such as infant feeding method, caffeine and surfactant treatment.
Physiological variable monitoring form: The form was developed to record heart rate (HR) (min) and oxygen saturation (% SpO2) values in the literature.
Pulse Oximeter Device: A pulse oximetry was used to determine HR and SpO2. The physiological parameters were measured and recorded every 15 minute for a total of 120 minute. The normal vital sign ranges assumed for the study subjects were as follows; heart rate range of 121 to 179 beats per minute, oxygen saturation range ≥92%. The pulse oximetry was calibrated as recommended by the manufacturer prior to use at the beginning of each shift within the study period. The pulse oximetry probe was attached to the foot of the leg.All of the measurements were performed by researcher who carefully and prudently recorded the infants' response throughout the study process.
Positioning material:
Rolled sheets were used when infants were given positions.
Statistical analysis:
Data were analyzed using SPSS version 22.0 (SPSS Inc., Chicago, IL, USA) statistical program. Descriptive statistics were reported using frequencies, percentages, mean values, standard deviation, and range. The Kolmogorov-Smirnov test was conducted to assess the distribution of the variables in order to use a parametric or non-parametric test. All the variables were normally distributed. Therefore, parametric tests such as analysis of variance and t-test were used to determine the differences in variables between groups. Variance analysis was used for repeated measurements of heart rates and oxygen saturation measured by infants at 15 min intervals. A value of p <0.05 was considered statistically significant.
Ethical considerations:
İn the study, written consent was obtained from the ethics committee, institutions and families.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Group 1:First supine position,then prone position
First group was supine position then prone position.
|
After the infants were treated and fed, supine position was first given and waited for 60 minutes to stabilise (no data was collected during this time).
After 61 minutes, it was allowed to stay in supine position for 2 hours.
From the 61st minute, heart rate and oxygen saturation were evaluated in each infant in the supine positions at intervals of 15 min over a period of 120 min.
At the end of two hours, the infant was given the prone position after the routine requirements such as diaper replacement were completed.
Infants were waiting for 60 minutes to stabilize after the prone position (no data was collected during this time).
From the 61st minute, heart rate and oxygen saturation were evaluated in each infant in the prone positions at intervals of 15 min over a period of 120 min.
