This study was conducted to determine the effect of mechanical vibration and ShotBlocker methods on pain level, crying time and procedure time during heel prick blood collection in healthy term infants.

Heel prick blood collection, which is one of the painful medical procedures, is one of the diagnostic methods used in newborns and is a more painful procedure compared to other blood collection procedures. Prevention of pain in newborns should be the primary goal of all healthcare personnel working with newborns, both because it is an ethical obligation and because repeated painful exposures have the potential to cause harmful consequences. Nonpharmacologic methods used for the control of acute pain associated with medical procedures are easy to use, have no side effects, are inexpensive and time-saving. Mechanical vibration and ShotBlocker application are among the non-pharmacologic methods frequently used in the management of pain associated with heel prick procedure in term infants.

Previous studies have shown that parent-related methods (kangaroo care, mother/father hug, breastfeeding, etc.) are commonly used for pain management of the newborn during heel prick. In this respect, it is important to determine the effectiveness of mechanical vibration and ShotBlocker methods that can be used independently of the parent, especially in intensive care settings where access to the parent is not always possible.

September through December of 2025

Individual participant data may be shared upon request from the principal investigator, subject to the appropriateness of the request, while ensuring adherence to the rules of confidentiality regarding individual data.

Using the block randomization technique, participants were divided into three groups. A web-based randomization list generation tool was used to assign participants to groups. Control and intervention groups were coded as A, B and C using the sealed envelope method. Randomization information was withheld from the researcher involved in data collection until data was collected. The researcher determines which group each baby is in. The researcher found out during the painful procedure. (investigator blinding).

Within the scope of the research, parents knew which group the baby was in. However, due to the nature of the sample group, the babies were blind.

To avoid statistical bias, study groups were coded as A, B and C; statistical blinding was performed (statistician blinding).
