Comparison Three Methods on Endotracheal Aspiration in Preterm Infants

The universe of the research; between July-September 2022, patients who are intubated on a mechanical ventilator at 32-36 weeks of gestation (middle preterm group) in Gaziantep Cengiz Gökçek Obstetrics and Pediatrics Hospital Neonatal Intensive Care Unit will consist of. In order to determine the sample size of the study, power analysis was performed using the G*Power (V3.1.9.7) program. According to Cohen's effect size coefficients; Assuming that the effect size (f = 0.4) of the evaluations to be made between four independent groups will be large/large, Taplak and Bayat (2021) found the effect size as 0.932 as a result of the Power analysis based on the PIPP-R results. In this study, it was determined that there should be at least 15 people in all groups (Fetal position, Swaddling, Prone position and control group) according to the new calculation made with 0.932 effect size, 5% alpha (two-sided) and 99% power. Considering that there may be losses during the study, each group will form a sample of 100 infants, 25 infants each. Random assignment of babies to groups will be carried out by the researcher through a computer program (https://www.randomizer.org)/. After determining the groups of premature babies randomly, one group will be given fetal position, one group swaddling position and one group prone position before, during and after endotracheal aspiration. Pain scores (PIPP-R), comfort scores (Comfort Scale) and physiological parameters (Heart peak beat, oxygen saturation value measured by pulse oximetry) 3 minutes before, during and after these nursing practices in the 1st and 3rd minutes after the procedure.
