A randomized crossover study was made to investigate the effect of different positions on the comfort, stress, and physiological functions of premature infants receiving non-invasive mechanical ventilation in the neonatal intensive care unit (NICU).

Positioning is a crucial care practice for premature infants receiving non-invasive mechanical ventilation, as it creates a safe and confined environment similar to the uterus. In addition to creating a secure environment, positioning supports skin integrity, aids respiratory and circulatory functions , prevents musculoskeletal problems, reduces pain and stress from treatment and care interventions, promotes safe sleep, enhances comfort, and thereby accelerates the recovery process. These practices provide numerous physiological and neurodevelopmental benefits. In premature infants, improper timing and technique in positioning can lead to major risks, including cranial deformities, restricted movement in the arms and legs, postural deformities such as ankle and shoulder extension, hip abduction, skin issues like decubitus ulcers, and respiratory and circulatory problems like venous return disorders, hypoxia, and apnea episodes. In the Neonatal Intensive Care Unit (NICU), positioning management is used to reduce infants' pain or discomfort from medical interventions and environmental stimuli. Maintaining proper posture also helps them cope with stress. Stress can negatively affect neonatal brain development. For patients and premature infants on mechanical ventilation, a nest-like bed can be created using towels, blankets, or similar materials that support a flexed posture and enhance comfort. In 24-hour periods, it is important to change the position regularly, at least every three to four hours. Properly positioning the infant in a flexed posture facilitates self-regulatory movements, such as sucking, bringing hands to the mouth, and moving hands over the eyes. Ensuring the infant's comfort reduces startle responses to harmful stimuli, conserves energy, minimizes stress, and helps maintain physiological balance. Reducing the infant's stress and enhancing comfort through developmental care supports neurodevelopment. Positioning is a non-invasive practice in caring for premature infants and forms a key part of developmentally supportive care. Nurses should adjust infants' positions according to their unique physiological conditions rather than relying on a single position, aiming to reduce sequelae associated with prolonged hospitalization and to support the infants' growth and recovery. According to researchers' observations and experience, premature infants positioned in quarter prone or stomach positions show better ventilation, better oxygenation, and fewer episodes of apnea. Due to the varying results in the literature, we recognize the need to validate these observations scientifically. The findings are expected to make a valuable contribution to our clinical practices and scientific knowledge in this field.In light of this information, our study aims to investigate the effects of positioning premature infants receiving non-invasive mechanical ventilation in the neonatal intensive care unit in different positions on their comfort, stress levels, and physiological functions (heart rate, SpO₂, and respiratory rate). It was tested the hypotheses that there Positioning premature infants in different positions (supine, prone, and quarter prone) during non-invasive mechanical ventilation in the Neonatal Intensive Care Unit does not affect their comfort levels, stress levels and heart rate, oxygen saturation (SpO₂), or respiratory rate.
