In the English law of tort, professional negligence is a subset of the general rules on negligence to cover the situation in which the defendant has represented him or herself as having more than average skills and abilities.
For decades, anesthesiologists advised patients not to eat or drink after midnight the night before surgeryâa guideline referred to as âNPO after midnight.â But many doctors now believe that some food and drinks, like tea or coffee without milk or cream, may be acceptable prior to a procedure.
On the day of your surgery: 1  You will usually be asked not to drink or eat anything for 6 to 12 hours before the surgery. 2  Take the drugs your doctor told you to take with a small sip of water. 3  Your doctor or nurse will tell you when to arrive at the hospital.
