Sudden illnesses are usually divided into traumatic illnesses and medical illnesses. In the case of traumatic diseases, such as wound lacerations, if the wound is bleeding, the wound should be dressed with a clean dressing with pressure to stop the bleeding. If the bleeding still does not stop, there may be a larger vascular injury and a ligature should be given to the limb proximal to the wound to block the blood flow and thus have a hemostatic effect. In addition, if it is a fracture, such as a fracture of an extremity, the fracture can be fixed with a hard board or a branch or paper bark, and then sent to the hospital for treatment. However, if it is a spinal fracture, such as the cervical or lumbar spine, try to make the patient lie flat and carry a hard board underneath to avoid the displacement of the fracture and causing secondary injury to the spinal fracture, which may produce serious sequelae by damaging the spinal nerves. In the case of multiple internal diseases, such as heart disease, such as angina pectoris, sublingual nitroglycerin can be administered if nitroglycerin is available. If it is an arrhythmia or myocardial infarction, try to take it to the hospital immediately for treatment. In addition, if you have a stroke and the patient is awake, you can take it orally if you have Aniuhuangwan at home. Whether it is a heart attack or other internal disease, try to avoid the patient to walk more during the process of sending to the hospital, because more walking may aggravate the condition, if possible, you can call 120 to request professional staff to come to transport.
