ABSTRACT
In the past few years, guidelines have been established for many medical indications. Guidelines are systematically developed recommendations which support doctors and patients in deciding on appropriate therapeutic measures in specific medical circumstances. Guidelines reflect the state of knowledge on effective and appropriate patient therapy at the time of publication. Guidelines must undergo periodic revision, replacement, and alteration in view of the inevitable advances in scientific knowledge and technology.The guidelines cannot be used in all circumstances.The decision as to whether a certain recommendation should be followed must be made by the doctor after consideration of the situation of the individual patient.
