I have suffered ( and recovered completely) from sepsis, septic shock on 2 occasions. I consider myself very blessed indeed. They were not from nosocomial infections but a immune deficiency. The 1st time I came entirely too close to dying twice. Both times including ICU stays, it is a very painful condition. Many patients lose limbs due to vascular collapse. It took a year to recover from the first episode, less from the second.
If spending less time in the hospital lessens the likelihood you could go through what I have....park your car in recovery !! Hospitals are even being remodeled/constructed with all rooms being private for infection control reason. I avoid surgery at all cost. I pray I never suffer another septic episode, I dont think my guardian angel would survive a third strike!
