Comparison of the effect of vibration bee with heat and cold on the pain caused by intravenous cannula insertion in children 3 to 6 years

Comparison of the effect of vibration bee with heat or cold on the pain of Intravenous catheter insertion in 3-6 years old children

A randomized controlled clinical trial (3 groups) with parallel group, double-blind ( evaluator and statistical).

location: Emergency Department and Clinic of Mashhad Pediatric Hospital. Patients will be included in the study with inclusion criteria and will be excluded if excluded. First, the purpose of the study is explained to children (who are eligible for inclusion) and their parents. After obtaining verbal consent from the child and written consent from the parents, the children will be included in the study. The intervention will be performed by the nurse injecting the intravenous catheter and the assessor will be blind. Questionnaires will be written in group code and the assessor will be blinded.

Child 3 to 6 years old with elective problem The first experience of injection for child in this admission. The child has no sensory-neurological, vascular, hematologic, verbal and cognitive impairment and chronic illness Before intervention, the child is alert and has not received sleepy, sedative and narcotic drugs.

First Intervention group : Heat vibrating bee group: The vibrate bee puppet, which is attached to a warm bag with a local heat of 39-40 ° C below, will be closed for 5 minutes at the location mentioned and in the last minute the vibration will apply. Second Intervention group : At the same condition; But the cold bag is used at zero degrees instead of the local heat. Control group ; Group of vibrating bees at room temperature

Reduce the pain of intravenous catheter insertion for children

The method used to generate a random allocation sequence is blocked. Block randomization ensures that there are no groups between the groups at any time interval during the randomization of a significant imbalance, and at each point the number of participants in each group is equal. Sampling in this research will be that sampling initially will be conducted in a "non-random" way for the purpose of children entering the research and assigning them to 3 groups (groups: vibration bee with heat/ vibration bee with cold/ vibration bee with room temperature) will be random; In this way, the assignment of samples to intervention groups (vibration bee with heat and vibration bee with cold) or control group(vibration bee with room temperature) will be done by random assignment (lottery by blocking). In this intervention, we have three groups; first by assigning the code to the groups, the groups will be determined(Group A: vibration bee with heat and Group B: vibration bee with cold and Group C: vibration bee with room temperature). 6 blocks with 3 pieces Characterized [(ABC(1)- ACB (2)-CAB (3)-BCA (4)- CBA (5)- BAC(6)]. Then, random numbers are selected between one to six (eg, 1, 4, 5, ...), and finally the list of treatment allocations based on random numbers will be determined. By drawing a lot, it will be clear what the sequence of doing the job is.

The nurse who do this procedure(Intravenous Catheter Insertion) draws and either cools or warms the pack itself (in the intervention group) or at room temperature (in the control group):Therefore, the researcher will be blind when scoring on the relevant tool (for evaluation of the outcome) . Only the code for each child's tool will be written: so the statistical evaluator will be blind.
