Pasternatsky Symptom

Pasternatsky symptom

Pasternatsky's symptom is a clinical sign described by the Russian physician Fyodor Ivanovich Pasternatsky (1845-1902).

The essence of the symptom is as follows: when pressure is applied to the projection of the cecum, a sharp pain occurs, which radiates to the right and anteriorly. This symptom is characteristic of inflammatory diseases of the cecum, such as appendicitis.

The mechanism for the development of the symptom is due to the fact that during inflammation, the nerve endings of the cecum become hypersensitive to mechanical stimuli. Therefore, even slight pressure in this area causes a painful reaction with irradiation along the nerve trunks.

Thus, the Pasternatsky symptom is an important diagnostic criterion for suspected acute inflammatory diseases of the cecum and is still actively used in clinical practice.

Pasternak's symptom Contents: - Pasternak's symptom (Pasternak's symptom) - determination of systolic murmur in the middle of the pulmonary field during inhalation and exhalation; elevation or depression of the upper boundary line of the relative dullness of the heart in a vertical position, caused by the inflation of the lungs with air during respiratory gas exchange. The same symptom may manifest itself in the form of an unchanged border of the right ventricle. The appearance of the symptom is due to the penetration of the sounds of cardiac activity into the lungs through the vena cava.

The symptom is characteristic of mitral valve defects and insufficiency, as well as atrial septal defects. It also appears with tetralogy of Fallot, pulmonary artery stenosis, and aneurysm of the interatrial foramen. In healthy people, it is determined during deep inspiration as a result of an increase in intrathoracic pressure with an increase in the blood capacity of the vascular bed of the lungs due to the expansion of the pulmonary capillaries. With strong body movements, straining, sneezing, the symptom intensifies - this is due to spasm of the internal muscles. Normally, the synchronous sign is not distinguishable; associated with the sound of blood hitting the wall of the pulmonary artery. The phenomenon is observed in severe anemia, the initial stages of the formation of blood clots in the cavities of large vessels. For rate
