In this study, it was aimed to examine the effect of therapeutic play applied with a toy nebulizer and toy mask before inhaler treatment on children's fear and anxiety.

It is the hypothesis of the study that the therapeutic play applied by using a toy mask and a toy nebulizer before inhaler treatment in children will reduce the child's fear and anxiety.

Acute diseases constitute the majority of applications made to pediatric emergency services. Inhaled drugs are frequently used in the treatment of childhood acute respiratory system diseases. Nebulizers are the preferred method of administering inhaled drugs. Medical procedures are one of the biggest fears of children, making it difficult to use nebulizers correctly and effectively. The negative reaction of the child to the mask and nebulizer during inhaler treatment causes incorrect inhalation patterns, reducing the safety and effectiveness of the treatment. This causes difficulties in relieving symptoms, increased hospital admission and hospitalization time, more treatment costs, and even negative consequences such as increased morbidity.

Reducing the fear and anxiety seen in children due to the hospital environment and illness is important in terms of children's acceptance of the treatment process. One of the methods used for this purpose is therapeutic play. Pediatric nurses should fulfill their nursing roles and responsibilities by including therapeutic play in their care processes.
