The difference between inhalation anesthesia and intravenous anesthesia is as follows: 1, the way of administration is different: inhalation anesthesia is to produce anesthesia by inhaling anesthetics through the nose, while intravenous anesthesia is to produce general anesthesia through intravenous administration; 2, the role played in different periods of surgery is different: the induction period of anesthesia, inhalation anesthetics work slower than intravenous anesthetics. During the awakening period, intravenous general anesthesia can wake up faster and better recovery of orientation, and the incidence of nausea and vomiting is lower than that of inhalation anesthesia; 3, the advantages are different: intravenous anesthesia is fast-acting and quick to wake up. Inhalation anesthesia is more convenient to administer; 4, the disadvantages are different: intravenous anesthesia is more expensive and has a greater impact on hemodynamics. Inhalation anesthesia may induce seizures and postoperative agitation in patients.
