Surgery includes fixing a condition of a patient using tools and modern equipment. This procedure is a long and complex process which may last up to 6 hours. There are many types of surgery such as keyhole. The types include elective surgery, which lets the patient decide wether if or how they want it to be done, emergency, which is done in quick response in order to save the victim, amputation, reconstructive, cosmetic and tranplantation.
The oldest surgical procedure was trepanning which involves boring a hole through the skull to let out spirits, or some believed. The first people to perform this task were the egyptians. When surgery evolved, medicines, instruments and techniques changed. Surgical procedures have to be in a clean area to not allow bacteria or harmful organisms to get in contact with the wound.
