Introduction to Anesthesiology

The term Anesthesia is derived from a Greek word with 'an' meaning without and 'esthetics' meaning sensation. Thus the meaning of anesthesia comes out to be 'without sensation'.

Anesthesiology is a branch of medicine that includes the complete care of a patient before, during and after the surgery. It can be defined as the usage of drugs in order to induce a total or partial lack of consciousness. This state is basically induced so that the patients don't feel any pain, distress or inconvenience during the surgery, and it can be carried out smoothly.

Anesthesia is induced by administering the patient with a drug known as 'anesthetics’. These drugs are a mechanism to reduce or prevent the pain during surgery. Anesthetics also support the vital functions of patients during the whole course of surgery. Anesthetics are administered during any surgery using spinal, caudal, intravenous or local procedures. The four primary types of anesthetics used in the health care industry:

Local Anesthesia: This anesthetic numbs only one particular area in which the surgery is carried out while keeping your consciousness intact.

Conscious or intravenous sedation: This anesthesia procedure utilizes a mild sedative to relax you and a pain medicine to relieve the pain. You will be conscious during such surgeries but generally don't remember anything.

Regional anesthesia: This anesthesia blocks the pain stimulators of a particular area in the body, such as arms or legs. Epidural anesthesia, generally used during childbirth, is a form of regional anesthesia.

General anesthesia: It induces a lack of consciousness to the entire body and makes you fall asleep. You don't tend to remember anything during these surgeries.
