Comfort Intervention in PICU Children

This randomized controlled trial will be conducted in a PICU to evaluate the effectiveness of a family-centered comfort intervention based on Kolcaba's Comfort Theory. Eligible children and their parents will be enrolled after consent and randomly assigned to an intervention group or a control group. The control group will receive routine nursing care. The intervention group will receive routine care plus a multidimensional comfort intervention including maternal voice exposure, environmental light regulation, and a weighted blanket. Child outcomes will include comfort, anxiety, fear, and sleep parameters. Parent outcomes will include state anxiety and satisfaction with care. Assessments will be performed at baseline, 24 hours after admission, and 12 hours after completion of the intervention. The primary objective is to determine whether the intervention improves child comfort and related outcomes, and whether it positively affects parental anxiety and satisfaction compared with routine care.
