Anesthesia is accomplished by giving medicine to control pain during a surgery or a procedure.

It can help by blocking your pain, relaxing you and making you sleepy or unconscious for your surgery.

All type of anesthesia is given to the patient while monitoring the patient vital signs like heart rhythm and rate, blood pressure, breathing, rate of oxygen in the blood and other parameters.

Several type of anesthesia can be administered depending on the type of surgery or procedure.
