Brief summary

This study evaluated the effects of ShotBlocker and a warm gel pack on pain, comfort, and physiological parameters during heel prick testing in healthy term newborns. A three-arm randomized controlled trial was conducted at a city hospital between October 2025 and May 2026. Newborns were randomly assigned to the ShotBlocker group, warm gel pack group, or routine care group. Pain was assessed using the Neonatal Infant Pain Scale (NIPS), and comfort was assessed using the Neonatal Comfort Behavior Scale (NCBS). Heart rate, respiratory rate, oxygen saturation, and heel temperature were also measured before and after the procedure. The study aimed to compare the effectiveness of these non-pharmacological interventions during routine heel prick testing.

Interventions

DEVICEShotBlocker

The ShotBlocker device was applied at the heel puncture site during routine heel prick testing. The device was positioned immediately before the procedure and remained in place during blood collection.

DEVICEWarm Gel Pack

A single-use warm gel pack was applied to the heel before routine heel prick testing. The heel temperature was maintained between 38°C and 40°C before blood sampling

Masking description

This was an open-label study. Due to the nature of the interventions (ShotBlocker and warm gel pack), blinding of participants and care providers was not possible. Statistical analyses were performed using blinded group codes to minimize analysis bias.

Intervention model description

Participants were randomly assigned in a 1:1:1 ratio to the ShotBlocker group, warm gel pack group, or routine care control group. Each participant received only the intervention assigned to their study arm during routine heel prick testing

Design outcomes

Primary

MeasureTime frameDescription
Neonatal Infant Pain Scale (NIPS) ScoreImmediately after heel prick testingPain intensity will be assessed immediately after heel prick using the Neonatal Infant Pain Scale (NIPS). The NIPS is a behavioral pain assessment tool consisting of six indicators (facial expression, crying, breathing pattern, arm movements, leg movements, and state of arousal). Total scores range from 0 to 7, with higher scores indicating greater pain intensity. Scores \>3 indicate clinically significant pain.

Secondary

MeasureTime frameDescription
Neonatal Comfort Behavior Scale (NCBS) ScoreBefore and immediately after heel prick testingComfort will be assessed before and immediately after heel prick using the Neonatal Comfort Behavior Scale (NCBS). The NCBS consists of six behavioral items, each scored from 1 to 5, yielding a total score ranging from 6 to 30. Higher scores indicate poorer comfort (greater pain/distress), whereas lower scores indicate better comfort. Scores ≥14 indicate discomfort/distress
Heart RateBefore and immediately after heel prick testingHeart rate was measured before and immediately after heel prick testing.
Respiratory RateBefore and immediately after heel prick testingRespiratory rate was measured before and immediately after heel prick testing.
Oxygen SaturationBefore and immediately after heel prick testingOxygen saturation was measured before and immediately after heel prick testing.
Heel TemperatureBefore and immediately after heel prick testingHeel temperature was measured before and immediately after heel prick testing.
