Anesthesia for bone marrow harvesting in the prone position in a patient with preexisting pericardial tamponade.

Refractory pericardial tamponade developed in an 18-year-old man with recurrent lymphoma. Invasive monitoring guided anesthetic management for bone marrow harvesting for autologous transplantation. The use of the prone position did not lead to adverse hemodynamic effects. The presence of a double pulse was demonstrated by pulse oximetry.
