About

A research protocol examining the effect of vibration on the crying duration variable in needle-related medical procedures in newborns also predicted that vibration therapy would be effective in reducing pain caused by vaccine injection and shortening the newborn's crying time.

Flicking the injection site can be used to control pain in childhood. To date, only one experimental study testing the flick method has reported that the flick method applied before intramuscular injection had lower pain scores in babies during and after vaccination.

Studies show that the positive effects of both methods are mentioned. However, no study has been found to examine the effects of both methods on injection pain that may occur when the second dose of Hepatitis B vaccine is administered in the neonatal period and compare their effects. The fact that the effects of mechanical vibration and flicking methods as pain relief strategies on reducing pain, physiological parameters and crying duration have not been examined in this population before shows the deficiency in the literature.This study aimed to examine the effect of flicking the injection site before the second dose of the Hepatitis B vaccine applied to the anterior surface of the vastus lateralis muscle in infancy and applying mechanical vibration to the injection site throughout the vaccination procedure on acute pain, crying duration and physiological parameters that may occur due to intramuscular injection.

Full description

Most tactile stimuli, such as vibration, have the potential to reduce pain because many large fibers are present in the skin. It is stated that mechanical vibration works primarily by turning off the ascending transmission of the nociceptive afferent nerve signal in the spinal-thalamic pathway and may provide an alternative or additional pain relief method for acute, short-term pain in newborns.

The use of hands is the oldest known and universal method for relieving pain. Methods such as manual pressure application (similar to the flick method) are used to reduce pain during invasive procedures.

Manual methods can be incorporated into clinical practice without additional cost or time. Experimental and clinical studies have suggested that various types of manual stimulation of certain nerve fibers (manipulations such as rubbing, applying pressure, and tapping just above or below painful areas) followed by the release of beta-endorphin into the bloodstream relieves pain.

Studies show that the positive effects of both methods are mentioned. However, no study has been found to examine the effects of both methods on injection pain that may occur when the second dose of Hepatitis B vaccine is administered in the neonatal period and compare their effects. The fact that the effects of mechanical vibration and flicking methods as pain relief strategies on reducing pain, physiological parameters and crying duration have not been examined in this population before shows the deficiency in the literature. This study will be the first to examine the effectiveness of vibration analgesia with the flick method in intramuscular injection pain in the newborn baby population in the same sample group and to compare the analgesic effectiveness of both methods.

In line with all this information, this study aimed to examine the effect of flicking the injection site before the second dose of the Hepatitis B vaccine applied to the anterior surface of the vastus lateralis muscle in infancy and applying mechanical vibration to the injection site throughout the vaccination procedure on acute pain, crying duration and physiological parameters that may occur due to intramuscular injection.

80 participants in 3 patient groups

Mechanical Vibration group

Experimental group

Description:

Babies randomized to the Mechanical Vibration group were subjected to vibration approximately 1 cm above the injection site with a mechanical vibration device before and during the vaccination procedure.

Treatment:

Other: mechanical vibration

Flick tapping group

Experimental group

Description:

Before the vaccination procedure, the vaccination site was placed on the nail of the middle finger in the babies randomized to the flick tapping group, and then the vaccination was stimulated with a quick tap using the upper nail part of the middle finger.

Treatment:

Other: Flick tapping

Control groups

No Intervention group

Description:

The routine vaccination procedure was administered to the infants in this group.
