The Effect of Scents Applied During Heel Blood Collection on Newborn Crying Duration, Pain, and Physiological Parameters

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.

About this study

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.

Primary outcomes

  1. crying times

    Time frame: Before the procedure, during the procedure, and for a total of 10 minutes after the procedure.

    measuring the crying duration with a stopwatch

  2. heart rate

    Time frame: Before the procedure, during the procedure, and for a total of 10 minutes after the procedure.

    Measurement with pulse oximeter

  3. Neonatal infant pain scale

    Time frame: Before the procedure, during the procedure, and for a total of 10 minutes after the procedure.

    The scale includes f ive behavioral parameters (facial expression, crying, armmovements, leg movements, and state of arousal) and one physiological parameter (breathing patterns). Each behavior is scored 0-1; the crying parameter is scored 0-1-2. The lowest score is 0 and the highest score is 7.
