Thus, 96 eligible children will be equally and randomly divided into one of two groups (intervention and control). A random allocation list will be generated based on quadruple blocks. To hide random allocation, a list generated by a statistician is used. The group assigned to each person has a special code that is a combination of numbers and letters and does not have a specific order. After sampling, the individuals are assigned to the groups in the order of the allocation list in the hands of the statistician.We will use sealedenvelop online software to generate random sequences. There are 4 blocks (permutations of two A and two B) and 24 blocks are randomly selected by the site, which will produce a total of 96 samples, Blinding description: Lavender essence and distilled water (placebo group) are poured into two similar glass containers. One person pours the essence oils onto a 4-by-4 gas and delivers it to another nurse (who is also blind to the drops used). The child is asked to hold the gas in front of her/his nose and inhale it for five minutes before the venipuncture. Outcome assessment is performed by another trained nurse who is not present in the room at the time of the intervention and is not aware of the type of intervention. N/A Condition 1: pain. Condition 2: Anxiety. Intervention 1: Intervention group: In the intervention group, five drops of natural lavender essential oil with a concentration of 2% (from Pars Pharmaceutical Idea Company) are poured on a 4 in 4 gas and the child is asked to hold the gas in front of his nose and inhale it for five minutes before venipuncture. Intervention 2: Control group: In the control group, five drops distilled water are poured on a 4 in 4 gas and the child is asked to hold the gas in front of his nose and inhale it for five minutes before venipuncture.
