Pre-admission Testing (PAT)
The levels of anesthesiology and the ability to block sensation with anesthesia drugs range from local anesthesia to general anesthesia with several levels in-between.
The decision of which anesthesia drug, or combinations of anesthesia will best meet the patient's needs, is made by an anesthesiologist. This is why a patient will go through PAT (pre-admission testing) prior to a surgical or endoscopic procedure.
During the PAT evaluation, the type of procedure, choice and volume of anesthesia drug, patient general health, patient age and genetics, and patient input as to what they would prefer (if possible) are all taken into consideration.
