Jugular vein examination

The jugular vein examination is an auxiliary examination method for checking whether the jugular vein is normal. When the normal person is standing or sitting, the external jugular vein is not exposed. In the supine position, it is slightly filled but only 2/3 of the distance from the upper edge of the clavicle to the mandibular angle. If the above level or semi-recumbent position is 45 degrees, the jugular vein When the filling is full and full, it is called jugular vein engorgement, indicating that the increase in venous pressure is abnormal. The jugular vein is the right atrial pressure gauge, which can reflect changes in right atrial pressure and volume. Because the right jugular vein is shorter than the left jugular vein and is a direct continuation of the superior vena cava, the right jugular vein is more than the left side. Can reflect the pressure changes in the right atrium. Basic Information Specialist Category: Cardiovascular Examination Category: Other Examinations Applicable gender: whether men and women apply fasting: not fasting Tips: Maintain a normal diet and schedule. Normal value When the normal person is standing or sitting, the external jugular vein is not exposed. In the supine position, it is slightly filled but only 2/3 of the distance from the upper edge of the clavicle to the mandibular angle. Clinical significance Abnormal results: When the examination was found, the jugular vein filling degree was more than 2/3 of the distance from the upper clavicle to the mandibular angle. Or obvious venous filling can be seen in the standing position and sitting position. May be suffering from right heart failure, pericardial disease and superior vena cava syndrome. Jugular vein engorgement with positive jugular vein pulsation is more common in severe congestive right heart failure with severe tricuspid regurgitation (functional or organic), and the veins of the patient's extremities (such as fingers) are seen with the heart. Contraction systolic pulsation. For jugular vein engorgement without hepatic congestion and/or lower extremity edema, superior vena cava obstruction (superior vena cava syndrome) should be considered. People who need to be examined: routine physical examination items, abnormal blood vessels. Precautions Forbidden before examination: Maintain a normal diet and schedule. Requirements for inspection: The light is suitable, the patient actively cooperates with the doctor to do the examination, and the doctor can check and chat while shifting the patient's attention in order to avoid the patient's excessive tension. Inspection process Inspection method: When the patient is in the supine position, the doctor examines the jugular vein to see if the filling exceeds 2/3 of the distance from the upper edge of the clavicle to the angle of the mandible. Or take a standing position and sit to see if you can see obvious venous filling. If there is the above phenomenon, it is seen in right heart failure, pericardial disease and superior vena cava syndrome. The jugular vein beats, the jugular vein beats softly, the range is diffused, and there is no pulsation during palpation, which is seen in the tricuspid regurgitation. Not suitable for the crowd Inappropriate people: severe blood vessels and heart failure. Adverse reactions and risks Nothing.
