One of the most common and painful procedures in newborns is taking a capillary blood sample from the heel. This basic procedure, widely used in early health assessments, particularly in newborn screening tests, can cause mild to moderate pain.While both pharmacological and non-pharmacological approaches are used in pain management in newborns, the primary goal is to minimize and prevent painful stimuli as much as possible. Non-pharmacological methods are preferred in newborn care because they have no side effects, are easy to apply, low-cost, and caregiver-friendly.

This study was designed as a prospective, three-arm, parallel-group randomized controlled trial. It focused on non-pharmacological methods (lavender oil, mandarin oil, control group/standard care).Mothers of newborns meeting the recruitment criteria were informed of the study before heel prick testing and provided verbal and written consent. The standard approach involves performing heel prick testing on all newborns in their mothers' arms.
