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.
In addition to not eating, it's best for individuals undergoing surgery to not smoke 24 hours before an operation. Anesthesia is well known for causing nausea and vomiting. Fatty foods, like pizza, take a long time to digest, so shouldn't be eaten the night before an operation.
