Septic shock is a result of a systemic response to infection or multiple infectious causes. The precipitating infections that may lead to septic shock if severe enough include but are not limited to appendicitis, pneumonia, bacteremia, diverticulitis, pyelonephritis, meningitis, pancreatitis, necrotizing fasciitis, MRSA and mesenteric ischemia.
The abdomen, the central nervous system, and the organs (including the lungs) are typically spared, but the extravasation in the extremities is sufficiently massive to cause circulatory shock and compartment syndromes, with a dangerous hypotension (low blood pressure), hemoconcentration (thickening of the blood) and hypoalbuminemia (drop in ...
Distributive shock is a medical condition in which abnormal distribution of blood flow in the smallest blood vessels results in inadequate supply of blood to the body's tissues and organs. [ 1 ] [ 2 ] It is one of four categories of shock , a condition where there is not enough oxygen -carrying blood to meet the metabolic needs of the cells ...
Diastolic blood pressure falls during the early stages of sepsis, causing a widening/increasing of pulse pressure, which is the difference between the systolic and diastolic blood pressures. If sepsis becomes severe and hemodynamic compromise advances, the systolic pressure also decreases, causing a narrowing/decreasing of pulse pressure. [ 23 ]
When the blood vessels suddenly relax, it results in vasodilation. In vasodilatory shock, the blood vessels are too relaxed leading to extreme vasodilation and blood pressure drops and blood flow becomes very low. Without enough blood pressure, blood and oxygen will not be pushed to reach the body's organs.
Vasopressors may be used if blood pressure does not improve with fluids. Common vasopressors used in shock include: norepinephrine , phenylephrine , dopamine , and dobutamine . There is no evidence of substantial benefit of one vasopressor over another; [ 36 ] however, using dopamine leads to an increased risk of arrhythmia when compared with ...
The effect on pH is moderated by the presence of respiratory compensation. Lactic acidosis is usually the result of tissue hypoxia which is not the same as arterial hypoxia. Adequate circulation of blood and perfusion of metabolizing tissue to meet demand is necessary to prevent tissue hypoxia. Lactic acidosis can also be the result of ...
This is especially the case if the sepsis gets worse, and even more if it becomes severe sepsis (where organ damage begins), septic shock (the organ damage continues, which lowers the blood pressure to the point where special drugs are needed to help keep it high enough), or multiple organ dysfunction syndrome (where organ damage can quickly ...
