[|AI|]  Hi, Thanks for writing in. Staph infection is very notorious in causing infections that can't be controlled easily. It releases toxin which affects normal body function and spreads through blood. Tracheostomy is done when a patient cannot breathe normally and normal amount of oxygen does not reach the lungs or the oxygen saturation starts falling. Kidneys and liver are important organs required to maintain proper functioning of the body by excreting toxic substances out of the system. He needs to be on life support until his system can take care of itself without life support. Doing surgery now involves a lot of risk, and he may not be able to withstand a surgery. That is why the doctors want to control the infection with medications. Hope this helps
