HOW MUCH TO TELL THE PATIENT?

Should patient be told about all the complications and dangers of the treatment and surgery?. As per the guidelines in certain countries only side effects which can occur in 10% of the patients or more should be told. And in some other countries side effects which can occur in 1-10% of patients should be told......BUT WHAT ABOUT COMPLICATIONS WHICH HAVE LESS THAN 1% OF INCIDENCE.....
WILL THERE BE INCREASE IN ANXIETY IN PATIENT WHICH CAN HARM WHEN PATIENT IS ON OPERATING TABLE
Note......not every patient is operated in general anaesthia.....some times patient is awake ....
