Brief Summary
Shotblocker is an effective approach to reduce injection pain. Generally, injection pain has been studied in children, but reducing injection pain in adults is an important issue. This study investigates the effect of ShotBlocker on pain and satisfaction levels associated with diphtheria-tetanus vaccination in pregnant women. The sample of this prospective, single-blind randomized controlled experimental study consists of 146 pregnant women registered to the Family Health Center between October 2018 and June 2019. Women were assigned to ShotBlocker and control groups with 73 women in each group. The women's pulse rate was taken one minute before the injection by the researcher. In the ShotBlocker group was used ShotBlocker. The control group used the steps of administering a normal intramuscular injection. The pain and satisfaction related to the injection were evaluated using the Visual Analog Scale and Visual Patient Satisfaction Scale after the vaccination. Pulse rates of the women were taken again by the researcher one minute after the injection.

Outcome Measures
Primary Outcomes (1)
Visual analog scale
The VAS is used to assess the severity of acute pain. It is mostly a horizontal or vertical line 100 mm long, starting with "no pain" and ending with "unbearable pain". It is used to convert some values that cannot be measured numerically to a numerically usable form \[10\].
6 month
Secondary Outcomes (1)
Visual patient satisfaction scale

Study Arms (2)
Shotblocker group
EXPERIMENTALIn the ShotBlocker group, ShotBlocker was placed on the previously determined injection site before vaccination, and the vaccination was performed by holding it on the surface of the skin and pressing lightly with the fingertips. All vaccinations were carried out by an experienced nurse. ShotBlocker was removed after removing the needle.
Control group
NO INTERVENTIONIn the control group, the steps of administering a normal intramuscular injection were used. Except for this, no additional method was used. All vaccinations were carried out by an experienced nurse.
Interventions
ShotBlocker (Bionix, Toledo, OH) is one of the methods that can be used to reduce pain caused by IM injections. This small, flat, U-shaped plastic device used by holding it on the skin surface during injection did not have any side effects \[5\]. ShotBlocker has a surface of 2 mm thick with rounded nubs to stimulate the skin (Figure 1). The surface of the plastic device is placed on the skin just before the injection; there is a hole in the center where the injection is administered \[6\]. The rounded nubs on the surface of the plastic device do not damage the skin, these rounded nubs that create a slight pressure provide a warning for the Gate Control Theory \[7\]
