Bone marrow aspirations in oncological patients: experience from an in-house standard in paediatrics

Nearly all paediatric patients require deep sedation when undergoing bone marrow aspiration (BMA). We analyzed the data from our protocols documented in a standardised procedure for bone marrow puncture over a period of 2 years.

Our standard included the documentation of personal data as well as vital parameters. In addition, we documented all medications administered, potential complications and required intervention measures, as necessary.

A total of 107 protocols were available for the evaluation. Our standard covered the usage of midazolam and S‑ketamine and resulted in complications in just 9 patients, which could be remedied using simple measures. For both active substances, the dosage necessary to reach sufficient deep analgosedation was significantly higher for patients under 24 months of age.

Our standard for BMA provides a practical and feasible procedure. In addition to good examination conditions, our standard also helps ensure the safety of our patients.
