The effect of three different methods (local skin cooling device, bubble machine, simulative toy) that will be used during the blood collection procedure on pain, fear and procedure time will be investigated in pain-sensitive 6-12 age group children.

Children are usually admitted to the hospital for diagnosis, treatment or follow-up at an early stage of their lives and are subjected to various invasive procedures during this process. Blood collection is one of the interventions that are repeated many times by children during diagnosis and treatment, causing a feeling of pain and fear. Although bloodletting may seem like a minor procedure, it is considered a source of great fear by children and therefore turns into an unpleasant experience by both children and their families.

Pain management is both an ethical obligation and a child's right, which should be done by focusing on the needs and preferences of children and their parents, requires accurate and effective planning. Nonpharmacological treatment methods used in pain management in children are classified into three groups: physical, supportive and cognitive-behavioral methods. The use of Coolsense, a local skin cooling device, is a method that can be used in this sense in terms of its rapid effect. Coolsense; it is a hand-held device that has an effect in as little as five seconds, does not contain chemicals, has a temperature-controlled head, can be stored in the freezer of refrigerators and used repeatedly. Among the advantages of the device are that it is easy to use, it is applied to a small area and it is easy to Decipher whether it is at the right temperature from the light burning on it. The most preferred method among cognitive-behavioral methods is the method of diverting attention Decently. The method of diverting attention is divided into two as active and passive methods. One of the methods of attracting active attention is the use of toys. One of these toys is a bubble machine. The bubble machine is a toy with the ability to produce a large number of bubbles at the same time with its multi-hole design. With this toy, the child focuses on the bubbles that come out through the bubble machine, and not on the painful process, so his attention is diverted from the blood collection process. Another one of the toys is a simulative toy. Simulative toy; it is a toy that can show realistic and vivid features, contains sensors sensitive to touch and movement, breathes, can open and close its eyes, can move its head and body, and at the same time make sounds as if it were real. With these features, it can be effective in reducing pain and fear by ensuring that children's attention is diverted from the painful procedure. It is thought that three different methods (local skin cooling device, bubble machine, simulative toy) that will be used during the blood collection procedure in pain-sensitive 6-12 age group children may have a positive effect on pain, fear and procedure time.
