The Effect of Distraction Method on Bone Marrow Aspiration Pain- a Randomized Clinical Trial

Introduction: Bone Marrow Aspiration (BMA) is one of the methods for diagnosis and treatment of various diseases, that now day it is widely use in regenerative medicine. Although this Procedure in adults is usually performed by using local anesthesia, it is associated pain. The purpose of this study is to research into the effect of Distraction Technique (DT) on patients who have undergone BMA for appeasement of pain.Method: This study was a parallel randomized clinical trial. 60 patients who underwent BMA were randomly divided into two groups. Intervention group received DT training and control group did not go through any training program. To measure the scope of severity of pain, Visual Analogue Scale (VAS) was used respectively.Result: Comparison of pain variable in study groups revealed that the mean score of VAS average in the intervention group has been lower than that of the control group and this difference was significant (P < 0.001 respectively). Comparison of vital signs before and after DBT showed reduced the vital signs after intervention. However ,no significant change was observed in control group.Conclusion: DT is an effective technique to reduce pain in BMA candidate. Nurses need to be aware pain procedures during BMA.
