At the end of surgery requiring general anesthesia, the anesthesiologist essentially reverses the effects of the anesthetic drugs.
Following surgery, the patient is allowed to wake up and once the anaesthetist has confirmed that they can breathe on their own, the tube is taken out.
Following this the patient is shifted to the recovery room where all the vitals are monitored. Nurses will be there to assist in case of any need. After an hour or so usually the patient will be shifted back to the ward.
The nurse and the doctor on the ward will provide instructions regarding the precautions to be taken and other advice regarding food, medication.
It is best to avoid solid foods on the day of surgery and in some cases the patient will be allowed to sip fluids once they are back on the ward. However if they have nausea this is best avoided.
