Preanaesthetic Checkup is the medical check up and certain laboratory investigations done by the anaesthesiologist before the operation to assess the physical status and any other medical problems/ diseases the patient might be suffering from.

Every patient MUST undergo PAC. This is to ensure safety of the patient. It provides an opportunity to detect and treat the patient's other medical diseases, the patient might be suffering from and to make the patient as fit as possible before the operation so that the risk involved in the operation can be minimized.
