According to "Prometheus" on the NOS forum:
Theron was in surgery this morning. It was successful but he is in critical condition.
The doctors give him a 48 hour window before they know if he will be okay. In the last 30 minutes his BP has come up. This is a good sign. She is receiving calls and says that all calls and prayers are welcome. She will be up all night to talk to any one who wants to know what is going on. She is also letting everyone know that all who can should come and visit to pay possible last respects.
Pray if you can.
His stepson has reported that an ulcer burst, and he is suffering from septic shock. Theron is on a ventilator, but he has been conscious and knows his family is at his side. The hope is that his blood pressure will rise enough (above 100) to place him on dialysis, but the morphine used to control his pain is currently keeping that blood pressure too low. Visitors are being restricted, as of Friday evening. He is at the Kaiser Medical Center in Riverside, CA.
If praying has given you an inside track with the Grand Architect of the Universe, please say some for our brother tonight.
