After a very long 8 hour wait at the clinic yesterday, the doctors decided to admit Oliver into the hospital for the weekend.  He received his VCR chemo drug but they were unable to sedate him for the bone marrow aspiration because some of his blood work, mainly sodium, potassium and glucose were low.  After IVs and a blood transfusion, Oliver made his way into the OR this morning where they successfully performed the bone marrow aspiration.  The OR is typically closed on Saturdays, but they fit Oliver in because of the importance of the procedure.  The doctors explained to us the reason it is so important that he receive the aspiration on schedule is to determine if he is a delayed/late responder to the chemo.  They have determined based on the labwork last week that he is not an advanced/early responder and his "road map" for future chemo treatments is highly dependent on the results of this test.  We are praying that he will not be a delayed responder to the chemo, but know that whatever the result, we have to take things day by day and that the doctors take such precautions to address these type of issues.  As for the duration of our hospital visit, we are hoping to be discharged tomorrow morning provided the electrolytes stabilize.  Oliver is in great spirits, has an excellent appetite and gained one pound from last week.
