The general anesthesia is a combination of medications that put the patients in a sleep-like state before surgery. Despite the fact that most of the oral surgical procedures are carried out painlessly under local anaesthesia, some procedures like orthognathic surgery or iliac bone harvesting, as well as dental implant patients that have excessive fear of surgery may require general anaesthesia. If the surgeon and the patient agree upon the type of anaethesia, an anaesthesiology consultation is mandatory to check the patients health status. After all the examinations reveal that the patient is fit for general anaesthesia, the hospitalization phase is underway. Send a message
