Diaphragmatic flutter
Introduction
fluttering introduction FlutteroftheDiaphragm refers to a paroxysmal or persistent paralysis of the diaphragm, accompanied by a sudden closing of the glottis during inhalation, resulting in a short, strange sound, a symptom that cannot be self-made, divided into Hiccup, Phenospasm, diaphragmatic flapping, and diaphragmatic spasm are rare. When it occurs, the diaphragm has a very fast and rhythmic contraction, which can reach 100 to 300 times per minute. basic knowledge The proportion of illness: 0.003% Susceptible people: no specific population Mode of infection: non-infectious Complications: epilepsy, rabies, tetanus, uremia, arrhythmia, sudden death
Cause
Nerve stimulation (20%):
This disease can be caused by local involvement of the phrenic nerve, vagus nerve stimulated or central nervous system disease, more common in early epilepsy, rabies, tetanus, rickets, uremia and other patients.
Primary disease (20%):
It can increase the excitability of the phrenic nerve or decrease the diaphragmatic stress threshold and produce diaphragmatic flutter. Frequent continuous episodes can form a stubborn phrenic ectopic excitatory foci and an abnormal excitatory-contraction coupling reaction ring, but the degree of bilateral tendon spasm Not necessarily exactly equal.
Prevention
flap prevention
There is no effective preventive measure for this disease. Early detection and early treatment are the key to prevention.
Complication
Complications, epilepsy, rabies, tetanus, uremia, arrhythmia, sudden death
Epilepsy, rabies, tetanus, rickets, uremia, arrhythmia, sudden death. Increased stress response, myocardial contractility, heart rate, blood pressure, coronary artery tension, shock, dehydration, hemorrhage, surgery or severe arrhythmia caused by sudden drop in cardiac output, coronary artery perfusion decreased sharply, high fever continued No retreat, shortness of breath, cyanosis, cough, hemoptysis and other symptoms.
Symptom
Flipping symptoms Common symptoms Dysphagia, chest pain, shortness of breath
When the diaphragm is sick, the diaphragm flutters to increase the negative pressure in the chest, and the airflow rushes into the upper respiratory tract. After a semi-closed vocal cord, a special sound is produced. The patient feels anxious, chest pain and inability to eat during the attack. If the duration is too long, the patient may consume severely. Even the mechanical contraction and bioelectrical disturbance of the heart may be caused by the diaphragmatic flutter. It may also affect the respiratory rhythm and depth, resulting in deterioration of cardiopulmonary function. Severe arrhythmia, sudden death, etc.
Examine
flapping check
Routine physical examination, B-ultrasound, X-ray. Another clinical application of pulmonary respiratory function tests, pulmonary ultrasonography, pulmonary alveolar, and lung compliance is the measurement of abnormalities in respiratory rate. Cardiopulmonary function examination, pay attention to check blood and urine lymph, electrolyte biochemical examination, combined with comprehensive diagnosis of the disease.
Diagnosis
flutter diagnosis
diagnosis
According to the patient's episodes of shortness of breath, chest pain and inability to eat, X-ray shows that the paroxysmal paroxysmal shape changes from upper convex to flat (mostly in the middle of inhalation or exhalation) is not difficult to make a diagnosis.
Differential diagnosis
Angina pectoris, myocardial infarction, costal cartilage inflammation, pulmonary embolism, lung malignancy, pleurisy, spontaneous pneumothorax and herpes zoster, pericarditis.
