Hello Linda,
I am a little over 5 weeks post op rt. Knee replacement. Due to my medical background, I looked at anesthesia based on my experiences. I opted for a spinal. I do not remember getting the spinal, nor the prep, nor the catheter insertion. They snow you with great happy drugs and that take away most of your memory. My hospital experiences in the recovery room showed most of the patient complaints were related to a sore throat from the tube they insert between your vocal cords when you are put to sleep. That was a major factor in my decision.
My surgeon utilized a pain control pump, pain pills, and a nerve block pump. While there was a delay in getting foot movement from the spinal, I was fairly comfortable for the first 24 hours. I knew going in that the first night might be my best shot at a fairly comfortable sleep. The next nights were not as restful and the 3rd day post op was my worst. The 3rd day was when my pca pump and nerve block pump were removed. Most agree that the better you stay on top of the pain the better. Don't try to tough it out....the knee will win.
Hope this helps. Tom
