Examination of "Shotblocker" effect on pain and patient satisfaction applied to tetanus+diphtheria vaccination in pregnant women

The study was conducted in a single-blind, randomized controlled experimental design to investigate the effect of ShotBlocker on pain and satisfaction level associated with tetanus vaccine in pregnant women. The research was conducted between October 2018 and June 2019. The sample of the study consisted of 146 pregnant women between 18-49 years of age who applied to a family health center in İzmir and were asked for Tetadif / 0,5 ml. Pregnants were included in the application and control groups by simple random sampling method. Pregnant women were given verbal and written information about the study and written consent was obtained from the pregnant women who agreed to participate in the study. The pulse rate of the pregnant women included in the study was counted one minute ago the application by researcher and then the vaccine was administered. The deltoid region was used as the injection site in all pregnant women and all vaccination applications were performed by a single experienced nurse. In application group; ShotBlocker was placed just before vaccination at the designated injection site and held on the surface of the skin during the injection, in control group, routine intramuscular injection application steps were applied. No additional method was used. Pregnants in both groups were administered Individual Identification Form after vaccination. Visüel Analog Scale was administered immediately after vaccination in order to determine the pain and Visüel Patient Satisfaction Scale was administered to determine satisfaction related to the injection and pulse rate was counted again one minute ago the procedure by researcher. One way ANOVA, Kruskal Wallis, Mann-Whitney U, Wilcoxon test were used for the analysis of the data. The mean age of the pregnant women was 27,80 ± 5,45 years. It was found that the mean score of pain severity related to tetanus vaccine was lower in the application group than the mean score of pain in the control group (p <0,001). The mean injection satisfaction score was higher in the application group compared to the control group (p <0,001). It was found that variables such as age of the pregnant women, whether or not a previous tetanus vaccine was administered, needle fear, smoking status and BMI did not affect the severity of pain perceived by the pregnant woman (p> 0,05). However, a significant difference was found between the pre- and post-vaccination pulse rates of the pregnant women in the sample (p <0,001). As a result; ShotBlocker has been shown to reduce the pain associated with tetanus vaccine and increase satisfaction with the vaccine. The use of ShotBlocker to reduce pain due to intramuscular injections and further studies with nonpharmacological methods are recommended.
