The Impact of Helfer Skin Tap and ShotBlocker Techniques on Emotional Responses to Intramuscular Injections in Children

Study Aim: This study aims to determine the effects of the Helfer Skin Tap Technique (HST) and ShotBlocker application on pain, emotional indicators, and physiological parameters during intramuscular (IM) drug administration in children aged 7-12 years. Study Design This research is designed as a randomized controlled experimental study. Study Setting and Characteristics The study will be conducted at the Pediatric Emergency Clinic of Fırat University Hospital. The Pediatric Emergency Clinic consists of two observation rooms with a total of 12 beds, where children's medication administration and follow-ups are carried out. The study population comprises children aged 7-12 years who received Vastus Lateralis IM drug administration (ZOFER® 8mg/4ml Injectable Solution - Ondansetron Hydrochloride Dihydrate) at the Pediatric Emergency Clinic of Fırat University Hospital and met the inclusion criteria during the specified study period. For sample size estimation, the pain scores from the study by Sivri, Bilgen, and Balcı (2019) were considered. Based on their findings (d = 0.82; α = 0.05), it was determined that a sample size of 40 children per group (HST, ShotBlocker, and control) would be sufficient. Considering potential dropouts, the sample size was increased by 10%, and the study was planned to include a total of 132 children who met the inclusion criteria and provided informed consent along with their parents.
