Study the effects of cognitive intervention in reducing pain intensity and changes in heart rate and blood oxygen saturation level

This research was conducted to study the effectiveness of cognitive intervention on reported- pain intensity and changes in heart rate and blood oxygen saturation level of children with cancer under the LP/IT. Another goal is the study of the relationship between pain and changes in heart rate and blood oxygen saturation level contributed to LP/IT. This research was a pretest-posttest experimental design with control group. 41 child–parent pairs were selected and randomly assigned to either an experimental or a control group. Children were visited twice. In the first visit, both groups were under routine hospital care and in the second visit, the experimental group received cognitive intervention and the control group received routine hospital care. Data were collected by demographic questionnaire, Oucher Scale and pulse oximeter device and analyzed with Analysis of Covariance and Pearson correlation tests. Results showed that group effect is significant and intervention had been effective in reducing reported-pain intensity, decreasing heart rate and increasing blood oxygen saturation level during LP/IT. There is a significant positive correlation between reported-pain intensity and changes in heart rate and a significant negative correlation between reported-pain intensity and changes in blood oxygen saturation level. Cognitive interventions are effective in reducing reported-pain intensity, decreasing heart rate and increasing blood oxygen saturation level during LP/IT. We recommend that to use cognitive intervention in pain management and reducing physiological changes.
