Syncope due to glossopharyngeal neuralgia or other visceral disease: this type of syncope is rare. Transient syncope occurs during lingual-pharyngeal neuralgia, biliary colic, renal colic, bronchial or gastrointestinal endoscopy. So, what tests should be done when patients present with syncope caused by glossopharyngeal neuralgia or other visceral diseases? The following is a brief introduction: 1. Blood routine is the most general and basic blood test. Routine blood tests are usually taken with peripheral blood examination, such as blood from fingertips and earlobe areas. After the blood cell analysis instrument, the computer reports the results, and this item has become a practice to examine patients. Blood consists of two major parts, liquid and tangible cells, and routine blood tests are performed on the cellular part of the blood. Blood has three different functions of cells – red blood cells (commonly known as red blood cells), white blood cells (commonly known as white blood cells), and platelets. Diseases are determined by observing changes in number and morphological distribution. It is one of the common auxiliary tests used by doctors to diagnose the disease. 2.Sugar, immune items, cerebrospinal fluid examination such as abnormalities have differential diagnostic significance. 3.Scientific examination angiography, CT and MRI, etc.: some patients can find the skull base malformation blood vessels. The following tests have differential diagnostic significance if they are abnormal. If syncope has occurred, it is best to have the patient lie flat on the floor. This way the cardiovascular system does not have to fight against gravity. Also turn the patient’s body to the side to avoid accidental aspiration. It is wrong to make a person sit after a syncope because then the blood has to flow upward to the brain.
