Propofol Lactated Injection is used for anesthesia. Propofol Lactated Injection is a general anesthetic that is used primarily for short-term procedures and has a rapid effect when administered intravenously. Indications for this drug include anesthesia maintenance, induction of anesthesia, and sedation of critically ill patients. By intravenous injection, patients can enter anesthesia within half a minute. Once the drug is discontinued for 3 to 5 minutes, or more than 10 minutes, the patient can wake up quickly, which facilitates postoperative patient recovery and postoperative patient observation. The main effects of Propofol Lactated Injection are inhibition of the circulatory system, inhibition of the carbon dioxide ventilation response, sedation and hypnosis, and inhibition of the pharyngeal reflex. The drug has the advantages of rapid onset of anesthesia induction, low incidence of postoperative vomiting and nausea, and rapid improvement of recovery function. In daily life, Propofol Lactated Injection needs to be used in well-equipped hospitals and must be used by professional anesthesiologists, not by oneself.
