It is a step-by-step procedure of the operation with extremity of the expertise of a single surgeon or a group in particular who coordinate themselves to complete the work in hand in a stipulated time period or in certain cases for hours and hours with absolute concentration because there’re no room for committing errors by any surgeon as it turns out to be the situation of `Life and Death`!

There’re different forms of `Surgical` aspects for different sphere of work involved as in some cases through normal surgical views a desperate and painful disease could be easily overcome whereas in sophisticated cases a broader in-advance or thorough planning is demanded by one so that the target can be achieved with in-depth analyses of the work involved. An act of performing surgery may be called a surgical procedure, operation, or simply surgery. Although it is sometimes difficult to determine when a medical procedure is considered surgery, a medical treatment that involves a cutting of a patient's live tissue (e.g., hair and nails are dead tissue) is usually considered surgery of some sort. A medical procedure involving a drilling of live tissue in a body would often be considered surgery, but mere piercing of a body is not necessarily surgery since piercing is often done for taking samples or draining fluids from or injecting materials into the body, or setting up intravenous drip, and usually does not require suturing to close the pierced opening. Even if a medical procedure or treatment does not include cutting or drilling of live tissue in a body, it may be considered surgery, if it involves common surgical procedure or a setting, such as use of an operating room or table in a hospital, anesthesia, antiseptic conditions, typical surgical instruments, and suturing or stapling. Surgery is considered an invasive procedure. Any surgical instrument which go into the body must be pre-sterilizes to avoid infection by micro-organisms. Also to maintain sanitation and sterility, surgeons clean (scrub) their hands. The surgical team wears sterile gloves during surgery. Surgical masks and gowns are also worn. Prior to surgery, particularly if it's non-emergency, the patient is given a medical examination, certain pre-operative tests, etc. In most surgeries the pain would be unbearable and a patient would not hold sufficiently still for a surgeon to precisely operate. `Open heart surgery` often involves placement of a patient on a heart lung-machine and lowering body temperature so the heart stops beating. When finished, body temperature is raised and, if necessary, an electrical impulse administered to restart the heart. Then, an incision is made to access the inside of the body area to be worked on as in a form of `Surgery`!
