The focus of first aid for sudden spasms is to avoid trauma and accidental aspiration. Patients have the possibility of falling when sudden spasms occur and are prone to fall injuries, and there are also dangerous objects in the environment that can easily cause cuts, stab wounds or bruises to patients. Therefore, once a patient is found to be in spasm, the patient should be placed in a safe environment as soon as possible, so that the patient can lie down on the ground or sit on the ground. In addition, if the patient is on the road when the spasm occurs, arrange warning signs as soon as possible to avoid secondary injuries to the patient from pedestrians or vehicles. Some patients have the possibility of vomiting during the onset of the disease. When the patient has vomiting impairment, let the patient’s head tilt to the side as much as possible and avoid lying on the back to avoid the possibility of life-threatening asphyxiation due to vomit.
