Effect Nursing Education on Anxiety, Pain and Vital Signs in Patients Undergoing Bone Marrow Aspiration- a Randomized Clinical Trial.

Bone Marrow Aspiration (BMA) is one of the methods for diagnosis and treatment of various diseases, widely used in regenerative medicine. Although this Procedure in adults is usually performed by using local anesthesia, it is associated with anxiety and pain. The purpose of this study is to research into the effect of Deep Breathing Technique (DBT) on patients who have undergone BMA for appeasement of pain and reduction of anxiety.Method: This study was a parallel randomized clinical trial. 60 patients who underwent BMA were randomly divided into two groups. Intervention group received DBT training and control group did not receive any training program. To measure the scope of anxiety and severity of pain, Spielberger State Anxiety Inventory (SAI) and Visual Analogue Scale (VAS) were used respectively. The Anxiety prior and pain after BMA were evaluated in two groups. By using t student test, chi-square test, ANCOVA and paired t test data analysis has been made. The significance level was set at 0.05.Result: Finally, 58 patients were analyzed (30 in DBT group, 28 patients in the control group). Comparison of anxiety and pain variables in study groups showed that mean score of anxiety and VAS average in the intervention group have been lower than that of the control group and this difference was significant (P = 0.018 and P < 0.001 respectively). According to Comparison of vital signs before and after DBT showed that the patients who were under the DBT, SBP (P < 0.001) and DBP (P < 0.001), HR (P < 0.001) and O2sat (P = 0.044) reduced after intervention. However , no significant change was observed in control group.Conclusion: DBT is an effective technique to reduce anxiety and relive pain in patients who were candidate BMA. Nurses need to be aware of procedural anxiety and pain during BMA.
