Clinical Trial Summary

Intramuscular (IM) injection is the most frequently used nursing practice in the clinic.1 16 billion treatments are performed through injection per year all over the world. Approximately 95% of these injections are administered for therapeutic purpose. There is no study result in the literature on the effect of vibration on pain in the ventrogluteal region in particular.

Description:

Intramuscular (IM) injection is the most frequently used nursing practice in the clinic.1 16 billion treatments are performed through injection per year all over the world. Approximately 95% of these injections are administered for therapeutic purpose.

If IM injections are not administered properly, they cause many complications such as primarily pain and cellulitis, muscular fibrosis and contracture, abscesses, tissue necrosis, granuloma, hematoma, and nerve injuries.Painful injections may lead to the development of fear and needle phobia. People are not able to comply with the treatment due to fear and needle phobia and they may even reject treatment. Pain developing after IM injection may vary based on drug content, individual factors and injection technique.

It has been reported that patients feel less pain and the other complications decrease when the correct technique of IM injection is selected. Different pain relief methods such as local ice application, changing needle before injection and acupressure are employed during injection. In the literature, mechano-analgesia, which is known as the skin stimulation methods, is included in pain management in addition to these methods.

One of the mechano-analgesia methods is vibration. The pain-relief mechanism of vibration is explained with the gate control theory. The theory, which is a similar mechanism used to obtain pain relief by rubbing an area near an injury, using TENS, or acupuncture. In the studies, it has been explained by the fact that the sense of touch and vibration obtained from skin receptors stimulate the intermediary inhibitor neurons in medulla spinalis through A-β nerve fibres. These neurons reduce the pain level in A-delta and A-C fibres in transmitting the signal received from skin to the second neuron, the signal cross over medulla spinalis and rises to brain. There are studies in the literature explaining that pain is reduced by vibration. Also, the vibration has advantages over other methods such as TENS, acupuncture as it is a method that is easy to apply, simple, applicable in all hours, and cheap and does not require any preparation.

Although the results of the related studies have indicated that this new method is effective in reducing injection pain, the number of studies on this method in the literature is limited. There is no study result in the literature on the effect of vibration on pain in the ventrogluteal region in particular.

Purpose of the study The purpose of this study was to assess the effect of vibration stimulation application in ventrogluteal region on intramuscular injection pain and patient satisfaction.

The specific study questions were as follows:

1. What are the effects of vibration on intramuscular injection-induced pain?

2. What are the effects of vibration on satisfaction for intramuscular injection?

Intervention

Device:
• Vibrating Device
The device used for the vibration application was produced to control pain and distract attention by providing vibration of 150 at 183 Hz (9000-11,000/min). The device is used again by being cleaned with 70% alcohol. The device was placed put 3 cm above the injection site. It should be ensured to completely contact with skin. Vibration was applied on the site for 3 minutes before injection

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	the effects of vibration on intramuscular injection-induced pain	Pain will be measures with Visual Analog Scale (VAS). The scale is composed of a 10-cm vertical or horizontal line, which starts with "No pain" on the one edge and ends with "worst pain" on the other edge. Patients should be informed about the use of VAS very well. Patients are asked to indicate the pain level by marking the appropriate point on the line.	Three months
Primary	the effects of vibration on satisfaction for intramuscular injection	patient satisfaction will be measured with Visual Analog Patient Satisfaction Scale .Visual patient satisfaction scale is combined with the characteristics of the well-known VAS (Visual Analog Scale). It is composed of a 100-mm horizontal line without numbers.	Three months
