Non-Pharmacological Methods in Heel Lance

Официальное название

Comparison of the Effects of Foot Bath, ShotBlocker®, and Buzzy® on Neonatal Vital Signs During Heel Lance

Обзор

This randomized controlled study was designed to compare the effects of Warm Foot Bath, ShotBlocker®, and Buzzy®-applied prior to heel lance-on the vital signs of newborns. Heel lance is one of the most frequently performed invasive procedures during the neonatal period, and the pain and stress experienced during the procedure may lead to alterations in vital parameters such as heart rate, respiratory rate, and oxygen saturation. Therefore, identifying non-pharmacological, safe, and feasible pain management methods is essential for enhancing the quality of nursing care. Data will be collected at three time points: before, during, and after the procedure, and changes in heart rate, respiratory rate, and SpO₂ will be recorded. With parental consent, the procedure will be video-recorded before, during, and after heel lance; the recordings will be anonymized and shared with experts for pain assessment. Additionally, the infant's crying duration and time to bleeding cessation will also be evaluated.

Подробное описание

This study was designed to investigate the effects of three different non-pharmacological interventions applied prior to heel lance on the vital parameters and pain levels of newborns. The study population consists of term newborns who meet the inclusion criteria, and the sample includes newborns who present with their parents to a state hospital for heel lance and meet these criteria. Following ethical approval, data will be collected between November 2025 and November 2026. Data collection will be carried out by Özlem Kum, a graduate student actively working in the relevant clinic and responsible for performing the procedures.

Pain will be assessed using the Neonatal Infant Pain Scale (NIPS), which evaluates procedural pain in both preterm and term newborns. The scale includes five behavioral indicators (facial expression, leg movement, arm movement, crying, and state of arousal) and one physiological indicator (respiratory pattern), with total scores ranging from 0 to 7. A 16-item Information Form containing maternal and neonatal characteristics will also be used. Statistical analyses will be performed using SPSS version 26, including frequency, percentage, mean, standard deviation, t-test, ANOVA, and Pearson correlation analyses.

Heel lance is one of the most frequently performed invasive procedures in the neonatal period. The pain and stress experienced during this procedure may lead to changes in vital parameters such as heart rate, respiratory rate, and oxygen saturation. Therefore, identifying non-pharmacological, safe, and feasible pain management strategies is essential for improving the quality of nursing care.

Non-pharmacological methods such as warm foot bath, ShotBlocker®, and the Buzzy® device are commonly used to reduce procedural pain through different mechanisms, including increased peripheral circulation, mechanical stimulation, vibration, and cold application. However, studies comparing the effects of these methods on newborns' heart rate, respiratory rate, oxygen saturation, and pain levels are limited.

This study will be conducted with approximately 90 clinically stable term newborns (37-42 weeks of gestation) in the Neonatal Unit of Kocaeli City Hospital. Data will be collected at three time points-before, during, and after the procedure-and changes in heart rate, respiratory rate, and oxygen saturation will be recorded. With parental consent, the procedure will be video-recorded at all stages, and anonymized recordings will be shared with experts for pain assessment.

The findings of this study are expected to contribute to the identification of effective non-pharmacological methods that can be used during painful procedures such as heel lance and to support the development of evidence-based practices in neonatal nursing.

Вмешательства

• Поведенческое Foot bath
  The infant's foot designated for blood sampling will be immersed up to the mid-calf level in water adjusted to 37-38°C, using a thermometer for confirmation, and kept there for 5 minutes. The heel lance procedure will then be performed by the nurse working in the clinic, following the standard clinical routine. The video recording will be stopped once bleeding has ceased at the end of the procedure. The video recordings obtained before, during, and after the procedure will be reviewed, and th
