Which type of shock causes an absence of bowel sounds?
Terms in this set (29) Which type of shock causes an absence of bowel sounds? Absence of bowel sounds is associated with hypovolemic shock. Decreased bowel sounds are seen with cardiogenic shock.
What are the main causes of shock?
Shock is a critical condition brought on by the sudden drop in blood flow through the body. Shock may result from trauma, heatstroke, blood loss, an allergic reaction, severe infection, poisoning, severe burns or other causes. When a person is in shock, his or her organs aren’t getting enough blood or oxygen.
What is shock and its types?
Shock is divided into four main types based on the underlying cause: low volume, cardiogenic, obstructive, and distributive shock. Low volume shock, also known as hypovolemic shock, may be from bleeding, diarrhea, or vomiting. Cardiogenic shock may be due to a heart attack or cardiac contusion.
Which body systems are affected by shock?
Shock, in physiology, failure of the circulatory system to supply sufficient blood to peripheral tissues to meet basic metabolic requirements for oxygen and nutrients and the incomplete removal of metabolic wastes from the affected tissues.
How many different types of shocks are there?
There are four subtypes of shock with differing underlying causes and symptoms: hypovolemic, cardiogenic, obstructive, and distributive. Distributive shock can be further divided into septic, anaphylaxis, and neurogenic shock.
What are the signs of distributive shock?
Distributive shock is difficult to recognize because the signs and symptoms vary greatly depending on the etiology. Common symptoms include tachypnea, tachycardia, low to normal blood pressure, decreased urine output, and decreased level of consciousness.
What happens during distributive shock?
In distributive shock, systemic vasodilation leads to decreased blood flow to the brain, heart, and kidneys damaging vital organs. Additionally, fluid leaks from the capillaries into the surrounding tissues, further complicating the clinical picture.
How do you manage distributive shock?
Treatment. The main goals of treatment in distributive shock are to reverse the underlying cause and achieve hemodynamic stabilization. Immediate treatment involves fluid resuscitation and the use of vasoactive drugs, both vasopressors and inotropes.
What is the focus of the initial management of distributive shock?
The initial management of distributive shock is to increase intravascular volume. The intent is to provide enough volume to overcome the inappropriate redistribution of existing volume. As with hypovolemic shock, administer 20 mL/kg of fluid as a bolus over 5 to 10 minutes and repeat as needed.
What causes distributive shock?
Distributive shock is caused by excessive vasodilation and impaired distribution of blood flow (eg, direct arteriovenous shunting), and it is characterized by decreased resistance or increased venous capacity from the vasomotor dysfunction.
