Safety of Sedation for Patients Undergoing Bone Marrow Biopsy and Aspiration While Febrile.

Objective: To determine the risks and outcomes of providing sedation to febrile patients scheduled for bone marrow aspiration or biopsy procedures.

Patients and Methods: During the 4-year period from January 1, 2013, through December 31, 2016, data from the periprocedural courses of 12,134 consecutive patients in an outpatient procedure center at a large tertiary medical center were collected retrospectively and analyzed to determine whether febrile patients undergoing bone marrow aspiration and/or biopsy with propofol sedation present a unique patient safety risk.

Results: Eighty-four patients (0.7%) had preprocedural temperatures of greater than or equal to 38.3°C. Of these, 6 required unanticipated hospital admission for sustained hypoxemia and symptoms suggesting pneumonia. All 6 of these patients had a productive cough and room air oxygen saturations of less than 92% before their procedures. These 6 patients were diagnosed during their hospitalizations with either confirmed or presumed community-acquired pneumonia. All recovered without pulmonary sequelae. Only 2 of the other 78 febrile patients required unanticipated hospital admission, for both general weakness and dehydration.

Conclusion: Our findings suggest that patients who are febrile and who also have productive coughs and oxyhemoglobin saturations by pulse oximetry of less than 92% would be best served with outpatient evaluation of their pulmonary symptoms before undergoing their elective bone marrow aspiration procedures. In contrast, febrile patients without pulmonary symptoms fare well.
