Shock An abnormal physiologic state where an imbalance exists between the amount of circulating blood volume and the size of the vascular bed .

An abnormal physiologic state where an imbalance exists between the amount of circulating blood volume and the size of the vascular bed .

Pathophysiology of Shock 1. Cellular effects of shock In the absence of oxygen, the cell will undergo Anaerobic metabolism to produce energy source and with it comes numerous by-products like lactic acid The cell will swell due to the influx of Na and H20, mitochondria will be damaged, lysosomal enzymes will be liberated, and then cellular death ensues.

Pathophysiology of Shock 2. Organ System Responses When the patient encounters precipitating causes of shock, the circulatory function diminishes  there is decreased cardiac output  Hypotension and decreased tissue perfusion will result

Shock Stages There are three stages of shock Compensatory stage Progressive stage Irreversible stage

There are three stages of shock

Compensatory stage

Progressive stage

Irreversible stage

Shock Stages THE COMPENSATORY STAGE OF SHOCK In this stage, the patient’s blood pressure is within normal limits . Patient’s blood is shunted from the kidney, skin and GIT to the vital organs- brain, liver and muscles Manifestations of cold clammy skin, oliguria and hypoactive bowel sounds can be assessed. Medical management includes IVF and medication Nursing management includes monitoring of tissue perfusion & vital signs, reduction of anxiety, administering IVF/ordered medications and promotion of safety

Medical management includes IVF and medication

Nursing management includes monitoring of tissue perfusion & vital signs, reduction of anxiety, administering IVF/ordered medications and promotion of safety

THE PROGRESSIVE STAGE OF SHOCK In this stage, the mechanisms that regulate blood pressure can no longer compensate and the mean arterial pressure falls. The overworked heart becomes dysfunctional. Heart rate becomes very rapid (as high as 150 bpm) Blood flow to the brain becomes impaired, the mental status deteriorates due to decreased cerebral perfusion and hypoxia. Laboratory findings will reveal increased BUN and Creatinine. Urinary output decreases to below 30 mL/hour.

Laboratory findings will reveal increased BUN and Creatinine. Urinary output decreases to below 30 mL/hour.

Shock Stages THE PROGRESSIVE STAGE OF SHOCK Decreased blood flow to the liver impairing the hepatic functions. Toxic wastes are not metabolized efficiently, resulting to accumulation of ammonia, bilirubin and lactic acids. The reduced blood flow to the GIT causes stress ulcers and increased risk for GI bleeding. Hypotension, sluggish blood flow, metabolic acidosis (due to accumulation of lactic acid), and generalized hypoxemia can interfere with normal blood function.

Shock Stages THE IRREVERSIBLE STAGE OF SHOCK This stage represents the end point where there is severe organ damage that patients do not respond anymore to treatment. Survival is almost impossible to maintain. Despite treatment, the BP remains low, anaerobic metabolisms continues and multiple organ failure results. Medical management is the use of life supporting drugs like epinephrine and investigational medications.

Hypovolemic Shock NURSNG MANAGEMENT: Primary prevention of shock is the most important intervention of the nurse. General nursing measures include- safe administration of the ordered fluids and medications, documenting their administration and effects. The nurse must monitor the patient for signs of complications and response to treatment. Oxygen is administered to increase the amount of O2 carried by the available hemoglobin in the blood.
