Anaesthesia is highly specialized procedure which entails three main activities.
- To produce & later on reverse the anesthesia.
- To avoid & treat any threats to patient’s well being ( including his life) during & sometime after anaesthesia.
- To control/treat associated medical diseases (like hypertension, angina, asthma, drug allergies, fits, diabetes, loss of blood etc.) during the anesthesia & for sometime after anesthesia. Anesthesia can thus be a complex combination of many medical activities being done at the same time. It is very important to know before hand, the patient’s general medical condition before an operation is done. It is important to know the risks to the patients health (&life) that can threaten him during and after the operation. These knowledge’s are acquired by anesthesiologist by doing examination & testing of the patient. Before he is actually anesthetized. PAC is a detailed medical, surgical, laboratory & radiological evaluation of patient’s condition. No trial of anesthesia is given during the PAC.
