After general anesthesia for enteroscopy, it usually takes 40 to 60 minutes to regain consciousness. However, for patients of advanced age, or other metabolic diseases, the recovery time is extended accordingly. General anesthesia, mainly through the respiratory tract inhalation, intravenous or intramuscular injection and other ways to make the anesthetic into the body, the patient is mostly accompanied by the loss of consciousness, the disappearance of generalized pain, skeletal muscle relaxation and other symptoms. Enteroscopy general anesthesia drugs, clinically common propofol, anesthesia drug stops, generally need 40 ~ 60 minutes after the anesthesia drug is metabolized or discharged from the body, the patient can gradually regain consciousness. It should be noted that, for the elderly, or combined with other systemic metabolic disease patients, the recovery time is correspondingly prolonged, need to pay more attention to clinical observation.
