The Effect of Shotblocker on Pain Violence and Injection Satisfaction

I Intervention Group: Before starting the application, the researcher informed the patients in the intervention group about the purpose of the study and their verbal and written informed consents were obtained.

The individuals to be included in the intervention and control groups were randomized by a faculty member at the Biostatistics Department of a university in the computer environment. The application was initiated by including the patients meeting the inclusion criteria on 04.12.2017. During the study, no intervention was made on the routine treatments of the patients in the intervention and control groups. Before the application, patient information form of each patient was filled using face-to-face interview technique.

Since the patients included in the study were discharged early (mean hospitalization duration was 3 days), the first, third and fifth SC heparin injection (0.6 ml) administrations were performed by the researcher for three days. The application was made to the arm area due to the fact that Shotblocker was difficult to place in the abdominal area, and the outer side of the arm was preferred for subcutaneous injection administrations in the clinic where the study was conducted. Shotblocker was placed on the injection site determined on the outer side of the upper arm of the patient and the injection was administered by gently pressing the tool with the fingertips during the injection. Shotblocker was removed after removal of the injector. Injections were completed in 20 seconds and the injection site was supported with cotton for 30 seconds. In the first minute after each SC injection application, the patients were asked about the pain level felt during the injection and the injection satisfaction status.

Control Group: Verbal and written informed consents of the patients included in the control group were obtained after they were informed by the researcher. Before the application, questions in patient information form were asked to each patient and how to use the VAS pain and injection satisfaction scale was explained. During injection, SC Clexan (0.6 ml) was injected on the site without using Shotblocker. Injections were completed in 20 seconds and the site was supported for 30 seconds. In the first minute after each SC injection administration, the patients were asked about pain level felt during the injection and injection satisfaction status.

In this study, the researcher administered all SC injections by throughout the study by considering the reliability of the study results.
