This study aims to compare the effectiveness of fluidized positioners and memory foam pillows in preventing pressure injuries in the head among pediatric patients.

H1: There is a significant difference between the fluidized positioner and the memory foam pillow in terms of pressure injury incidence in pediatric intensive care patients.

H2: The fluidized positioner reduces the risk of developing pressure injuries more effectively than the memory foam pillow.

H3: There is a significant difference in the pressure applied to the head region of the patient between the fluidized positioner and the memory foam pillow.

H4: The anatomical locations of pressure injuries (occipital, parietal, temporal, and ear regions) vary depending on the type of pillow used.

H5: Compared to the memory foam pillow, the fluidized positioner is associated with a more homogeneous pressure distribution across the occipital, parietal, and temporal regions.

Inclusion Criteria:

• Parents want to leave at any stage of the project
• Having hydrocephalus or burn in the head area
• Having PIs on admission to hospital
• Existing dermatologic diseases affecting the skin or connective tissue
• Having emergence of a new condition during the intervention may significantly affect the risk of pressure injury (e.g., sudden surgery or complication)
