Design outcomes

Primary

MeasureTime frame
Pain intensity in the visual analogue scale. Timepoint: Pain intensity immediately, 30 minutes, and then the day after the bone marrow biopsy. Method of measurement: By using a visual analogue scale questionnaire.;Anxiety severity using the Speilberger State–Trait Anxiety Inventory questionnaire. Timepoint: Patient's anxiety level 5 minutes before BMAB. Method of measurement: by using Speilberger State–Trait Anxiety Inventory questionnaire.

Secondary

MeasureTime frame
The amount of painkillers required to reduce pain, the total dose of painkillers (including opioids, acetaminophen, and NSAIDs) used after BMAB in each patient. Timepoint: Patients are monitored for 24 hours after the end of BMAB. Method of measurement: Patient's record.;The need for sedatives to reduce anxiety. Timepoint: Patients are monitored for 24 hours after the end of BMAB. Method of measurement: By using patient record data.;The time required to administer the first dose of pain medication. Timepoint: Patients are monitored for 24 hours after the end of BMAB. Method of measurement: By using patient record data.;Time required to administer the first dose of a sedative. Timepoint: Patients are monitored for 24 hours after the end of BMAB. Method of measurement: By using patient record data.;Patient satisfaction with the procedure. Timepoint: The morning after BMAB. Method of measurement: The patient's level of satisfaction with the procedure is evaluated with the question "Are you willing to repeat the procedure with the same amount of pain reliever/anti-anxiety medication?" (yes/no). In this regard, if the answer to the satisfaction question is yes, the patient is considered "satisfied". Satisfaction with the procedure - yes - no.;Pain score on the visual analogue scale. Timepoint: One month after performing BMAB, the presence or absence of pain and then its intensity are recorded in patients. Method of measurement: By using visual analogues scale.;The memory of pain a month later. Timepoint: The patient's memory of the pain experience caused by BMAB is evaluated in a telephone call after one month Community Verified icon. Method of measurement: In this regard, if the answer to any of the three questions including "dreaming about this event", "feeling like running away from thinking about this event" and "feeling overwhelmed by thinking about this event", is yes, the memory of pain The patient is considered "positive".
