Definition of Anesthesia:
Anesthesia comes from the Greek word “anaisthetos”, meaning without sensation.
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.
Type of Anesthesia:
- General anesthesia: used in most type of surgery, it makes you unconscious while pain free till the end of surgery.
Medication is administered through an intravenous line or inhaled through a breathing mask or tube.
At the end of the surgery, anesthesiologists stop giving you anesthesia, reverse your state of unconsciousness and carry you to the recovery room for further monitoring.
