Effect of Cough Trick Method and Pinwheel Blowing in Blood Collection

Purpose of the study: This study aimed to examine the effect of the cough trick method and pinwheel blowing on the severity of pain during blood collection in school-age children.

Type of Study: It is a randomized controlled study.

Location and Characteristics of the Study: It will be conducted in the pediatric blood collection unit of Fırat University Hospital, with children aged 6-12 who are subjected to blood tests by a pediatrician.

Population-Sample: The population of the study will consist of children who applied for blood collection in the pediatric blood collection unit of Fırat University Hospital. A pilot study will be conducted to determine the number of samples. For the pilot study, 20 participants will be taken from each group and a total of 60 samples will be taken. As a result of the pilot study, power analysis will be performed and the number of samples will be determined. Randomization will be done to assign the participants to the groups. Grouping will be done using simple random sampling. Randomization will be provided using the Random Sequence Generator on the www.random.org website. Each participant who volunteers to participate in the study and meets the criteria will be given a number. Accordingly, which number will take place in which group will be determined in advance.

Data collection tools: Questionnaire", "Visual Analogue Scale (VAS)", "FLACC Pain Rating Scale" and "Wong-Baker Faces Pain Rating Scale (WBFPRS)" will be used to collect data.

Data Collection: The research will be carried out in three stages. Stage 1: Groups of parent-child pairs who come to the blood collection unit, voluntarily participate in the research, and meet the inclusion criteria will be determined in line with the randomization method within the scope of the research. Study data will be collected in 3 groups. Two groups will be the intervention group and the third group will be the control group.

Group 1: cough trick group 2nd group is the pinwheel blower group. Group 3 will constitute the control group. Stage 2: Information about the children assigned to the groups will be obtained using the "Introductory Question Form".

Stage 3: Blood collection will be performed by the same nurse (a volunteer nurse with 5 years of experience in pediatric blood collection) to eliminate differences that may occur due to nurse differences. Blood samples from children will be taken with a 21 gauge x 1.5 inch vacuum blood collection needle. It will be ensured that the parent accompanies the child throughout all procedures.

Pain intensity will be measured through observation and physiological responses of the child, parent, and nurse. The child's pain intensity will be rated by the parent, the nurse (a pediatric nurse with 5 years of experience, independent of the blood draw) and the child himself before and after the blood draw. To determine pain severity, parents will use VAS, the nurse will use FLACC, and the child will use FACES scale.

Heart rate is the physiological measure used to report pain intensity, and the heart rate of the children in the study will be recorded before and after the procedure using a pulse oximeter device at 2-minute intervals. The demographic questionnaire will be filled out by the children's parents 10 minutes before the procedure.

The statistical significance level of the study was determined as p< 0.05. In addition, at the end of the research, the status of working with sufficient sample size will be tested with post-hoc power analysis.
