what do they first treat a wound with in a hospital? alcohol? "spiritus"? and how does it kill germs exactly?

and how does soap kill germs?
Answers:
Alcohol would not be used to clean a wound as it would destroy healthy tissue cells. A wound caused, for instance, in a RTA may need cleaning of foreign objects such as glass or soil and this can be done by gentle irrigation with saline or surgical removal if necessary. During the healing process sloughy tissue may form (dead cells) and again these can be removed by irrigation with saline. Extensive areas of dead tissue would have to be removed to promote healing. There are also some products which can break down dead tissue and may be applied in the form of a gel or paste. Often silver is incorporated in wound dressings as this has been found to have an anti-microbial property. For 'open' wounds ie where the surrounding skin cannot be brought together by stitches or adhesives, when the wound is clean the aim is to create a moist (but not wet) and warm (body temperature) environment to promote healing.Substances such as iodine should no longer be used as it has been found to be absorbed and is harmful - although some surgeons continue to use it. Soap does not kill bacteria but breaks down grease and helps to clean the skin. Effective washing technique helps to remove bacteria but alcohol gels are more effective than washing with soap.

Alcohol kills by dehydrating the cells; soap makes the water-insoluble particles aggregate and kind of also water-soluble, but it may not exactly 'kill' germs. Soap has some dehydrating action also. So, soap is a surfactant.
