What needle was stuck on the foot after general anesthesia?

After general anesthesia, I stuck an intravenous indwelling needle in my foot. According to the inquiry, a quick question to the doctor showed that an intravenous indwelling needle was placed on the foot after general anesthesia. General anesthesia refers to intravenous anesthesia with tracheal intubation, indwelling needle in hand or foot vein, intravenous injection of sedatives, muscle relaxants and tracheal intubation to maintain breathing. The whole process is basically unknown. General anesthesia is called general anesthesia for short. It refers to the temporary inhibition of the central nervous system when anesthetics enter the body through respiratory inhalation, intravenous or intramuscular injection. The clinical manifestations are loss of consciousness, general pain, amnesia, reflex inhibition and skeletal muscle relaxation.
