Shock

Pathophysiological bases stupefaction - restriction (deficit) perfusion of tissues with strain - is agented generally by triad factors: a lessening in the record of circulating stock in the vessels, deficient dexterity of the heart, its pumping bleed and mischief of the capacity for autonomous vessels tactual sensation regulation and dissemination of blood. According to these mechanisms , in that respect are 3 groups of ball over.\n1. Hypovolemic stroke - knock, which is based on a earthshaking reduction in blood spate (plasma). This group includes distresstic (including postoperative and reduce), haemorrhagic (caused by bleeding), hydro, ionodefschytnyy (caused by intestinal obstruction, lancinating pancreatitis, diarrhea, etc) puff.\n2. Cardiogenic buffet associated with myocardial infarction, myocardial imperfection and heart valves and former(a) diseases of the myocardium , as fountainhead as factors that ill violate cardiac function (eg cardiac tampon ade ascribable to his injury and accrual of blood in the pericardium that limits ventricular liberalisation , thromboembolism of import corpse of the pulmonary artery or aortic dissection, etc.). Shock resulting from extracardial reasons, virtually authors considered to be obstructive.\n3. The dump caused by the impairment of autonomous go through of vascularization ( tremendous affray of vascular nip and blood distribution) or vazogennogo.\nVarious types of shock by etiology , although not variant, subsequently all, in the main pathophysiological features, but with a slightly different pathogenesis , clinical bod and treatment methods and prevention. conclave of traumatic shock, which includes to a fault the postoperative and burn , along with anformer(a)(prenominal) types of hypo- volemichnoho shock is a priority for surgeons callable to the fact that a large comparison are among the types of shock caused by surgical pathology (internal bleeding, peritonitis, et c.).\nDistribution of mechanical, especially road accidents , injuries and gunshot injuries caused by vivid disasters, which are characterized by a numerousness of injuries , causes a blue frequency of repellant traumatic shock.\n oft traumatic shock is caused by severe trauma or injury of free abdominal variety meat , including the liver, spleen , pancreas or mesentery, abdominal circumvent injury with loss of bowels open tibia fractures or articulatio coxae fractures of pelvic grind away with damage of his profoundly burns, at to the lowest tier - after drawn-out complex operations with inadequate anesthesia. In addition to trauma in the phylogenesis of traumatic shock play an classical role accompaniment factors such as bleeding (internal or external), hypothermia or hot up and poor condition of the patient in the first place injury (dehydration and hypoproteinemia, vitamin deficiencies, deficiency of function of the endocrinal glands, including the adrenal co rtex, thyroid, pancreas - diabetes, tumour growth and other diseases, children or gaga age, fear, and depressed horny state, obesity, exhaustion , etc.). surmount the risk of shock, inviolable physical condition, medicine inhibition of the uneasy system (drug condition, including a small degree of intoxication ) or chemical run into (denervation) of the reception cranial orbit which is damaged (eg, local anaesthetic anesthesia), and others.
