A 5 percent glucose solution is frequently administered to the blood of persons who have undergone surgery. Why? What affect does this have to the person or to their blood?

Hmm, that's a good question.
Here's my shot at an answer, though the reference below refers primarily to children, I imagine that the same is true across the board...
Even a relatively short period of inadequate nutrition can lead to decreased host resistance, increased infection, and poor wound healing, which can contribute appreciably to morbidity and mortality in those with surgical disease.
Not only must the metabolic demands that a major illness or operation imposes on all patients be taken into account. Rapid growth, highly variable fluid requirements, coupled with low caloric reserves in the sick children, make adequate nutritional intake particularly important.

Many people are not going to be able to take food orally for a period after surgery. The glucose doesn't give many calories, and the body will have to use other methods to get its energy, but the brain requires glucose and takes some time to make an adjustment. Just ask anybody who's been on the Atkins diet. So the brain gets its glucose, the body does its little bit of ketosis, and everything works out OK.

To ensure that the patient has dextrose to keep blood sugars in check in a pt who may not be able to eat or drink for some time after the surgery. Usually they will receive and IV solution of D5 1/2 NS or plain Normal Saline. There are many factors as to why a pt requires a specific type of IV solution and they are usually chosen to meet that pt's particular needs.

D5W (5% dextrose) has about zero nutrition (for that you would give D10, D12 or higher in TPN). It is given as opposed to normal saline, because it is iso-osmotic, with out the salt load. It is not administered very often; more often the IV of choice is saline (1/2 normal--not advised in current literature, normal saline etc), ringer's lactate.
