Drug poisoning is very common in clinical practice, and once drug poisoning occurs, the first step in care should be to stop the continued absorption of the poison, mainly through gastric lavage, enema, and diarrhea to prevent the continued absorption of the poison. The care of drug poisoning also includes the rapid opening of intravenous channels, the removal of foreign bodies from the mouth, and the maintenance of a clear airway. Patients who are unconscious should be cared for by diligent suctioning and turning, and they should sleep on their sides with their heads tilted to the side to prevent asphyxia caused by oral secretions entering the trachea. The care of drug poisoning includes dietary adjustment and later life care, and the patient’s vital signs should be monitored, such as blood pressure, heart rate, body temperature, respiration, etc. should be tested in time.
