For every two steps forward, it seems we go one step backward. Today Dad passed a lot of blood throughout the day. But his hematocrit levels actually went up today, so they believe that the bleeding probably occurred yesterday and was just passed today. It is believed that the bleeding was due to the ischemic colitis. He was pulled off heparin (the blood thinner) for most of the day. After coming to their conclusions, it was decided to go ahead and put him back on the heparin tonight. If all goes well through the night and tomorrow, they will take him off of it. And then he will go to the daily lovenox shots.
The reason for using the heparin before going to the lovenox shots is for exactly this reason. If bleeding occurs, he can be taken off the heparin and the effects leave the body rather quickly. Whereas once the shot is given, I don't know for sure what would or could be done if bleeding occurs.
All in all, it was a rather stressful day, but we are thankful that things were not as bad as they seemed at some points today.
