Surgery is a branch of medicine concerned with treating diseases and injuries by means of operative intervention, which means a surgeon operates on a patient in order to treat an injury, improve the functions of the body or the patient's appearance.
The word 'surgery' originally comes from Greek, in which language it means 'hand work'. This is actually a very adequate name, as a lot of procedures are performed in an operating room manually, with the use of modern tools and medical devices.
Let's have a look at some of the common types of surgeries, circumstances when surgeries are necessary, the professionals involved in them and the equipment used. When there has been a traffic accident and an injured person is brought to the hospital's A&E department, emergency surgery might be required, i.e. one which has not been planned and arranged by the hospital's staff. The patient is usually rushed into the operating room where doctors perform the surgery.
Before doctors begin the operation, they have to scrub up and make sure that the tools & equipment used are sterile. If necessary, drains are placed to remove blood from wounds. After the surgery has finished, a suture is applied to hold tissues and skin together and the patient is taken to the recovery room where his or her health is monitored.
