[Event] Plastic surgery tragedy, consultation about general anesthesia. The jargon is “surgery is big or small, anesthesia is not big or small”. You can’t cut a shallow anesthesia, cut 2 anesthesia on a deeper. The anesthesia needs to reach a painless level before you can move the knife. General anesthesia classification] non-intubation general anesthesia (general anesthesia, according to the complexity of respiratory management is divided into: non-intubation, insertion of a laryngeal mask, insertion of a single-lumen tracheal tube, insertion of a double-lumen airway tube four kinds). Non-intubation anesthesia] Non-intubation means that the patient keeps breathing on his own, and analgesics + anesthetics are used to make the surgery painless. The other three will be helped by the machine to breathe, but also need to add other drug substances. Non-intubated general anesthesia is used for short, minor surgeries. The most common complication of this type of anesthesia is hypoxia. The patient cannot breathe by himself during the operation, and there is no machine to help, so the doctor needs to concentrate on timely detection before he cannot detect abnormalities in time. [Avoid Accidents] After this type of minor surgery, the patient is fully awake and usually goes back to the ward or outpatient observation room, sometimes, for various reasons, the patient will “fall asleep” again. This is especially common in obese people who happen to have no monitoring equipment. In this case, it is important to talk with the patient for a while (tell stories, tell happy stories) to keep the patient awake. It may seem cruel not to let the patient sleep after surgery, but it is actually the best help for the patient.
