Nursing Diagnosis: Risk for shock
Definition: A condition in which the body’s tissues are at risk of inadequate blood supply and are susceptible to life-threatening cellular dysfunction, potentially threatening health.
*In the 2021 version, the definition has changed slightly.
Definition: A potentially health-threatening condition that is likely to result in inadequate blood supply to tissues that can lead to cellular dysfunction.
1. What is shock?
Quoted from the Japanese Association for Acute Medicine → Shock Japanese Association for Acute Medicine Medical Glossary (jaam.jp)
1) Definition of shock
A life-threatening acute syndrome in which blood flow to vital organs cannot be maintained as a result of an invasion of the body or a biological response to an invasion, resulting in cell metabolism disorder and organ damage. A decrease in systolic blood pressure below 90 mmHg is often used as an index. Symptoms such as tachycardia, facial pallor, and cold sweats are typically caused by sympathetic nervous system tension. In recent years, a new classification of shock based on circulatory disturbance factors has come into use, and it can be roughly divided into the following four categories.
2) Pathophysiology and 5 signs of shock
We will break down and understand the definition of shock by the Japanese Association for Acute Medicine.
“Invasion to the living body” means “infection, surgery, injury, bruise, heart disease such as acute myocardial infarction, allergens that cause anaphylaxis, and substances that stimulate nerves.”
“Results of biological reactions to invasion” are defined as “decrease in circulating blood volume in the case of hemorrhage, weakening of cardiac contractility in the case of myocardial infarction, disruption of blood distribution balance between the periphery and the center in the case of sepsis due to infection, vagal reflexes, etc. Nerve stimulation results in a decrease in cardiac output and a decrease in heart rate due to parasympathetic nerve dominance.”
“The blood flow of vital organs cannot be maintained” means “decreased perfusion pressure”. Perfusion is the flow of fluid through an organ. “Perfusion pressure” is the pressure for blood to flow into organs (tissues and cells). That pressure is “blood pressure”. Pressure has the characteristic of moving from high to low. Blood pressure is circulating blood volume x vascular resistance. Any decrease in either will decrease blood pressure. A drop in blood pressure means a drop in the pressure for perfusion to the periphery, so “blood flow to vital organs cannot be maintained.”
However, this decrease in perfusion pressure does not end as it is. When the blood flow to the tissue is reduced, the tissue becomes starved of oxygen. It promotes anaerobic metabolism. Lactic acid accumulates during anaerobic metabolism, causing the body to become acidic (acidosis). In acidosis, arterioles dilate, but venules dilate poorly. Blood is transported to the periphery by dilation of the arterioles, but because the venules cannot collect blood, stagnation of blood flow in the capillaries and extravasation occur, and central blood flow decreases. .
It states that “a decrease in systolic blood pressure of 90 mmHg or less is often used as an index,” but all four shock categories cause a decrease in blood pressure.
To summarize, it is a life-threatening acute disease in which blood pressure (circulatory blood volume x vascular resistance) cannot be maintained due to various causes, perfusion pressure in tissues decreases, and dysfunction occurs in important organs. increase.
(2) Five signs of shock (typical symptoms)
It is a sign of dysfunction in a vital organ. Famous, isn’t it?
③ Cold sweat (perspiration)
⑤ Pulmonary insufficiency
3) Four categories of shock (cause)
Shock is classified into four types according to the cause.
(1) Circulatory hypovolemia
Decrease in circulating blood volume: Blood pressure↓・Heart rate↓・Cardiac output↓・Central venous pressure↓・Peripheral vascular resistance↑
(2) Cardiogenic and extracardiac restriction
Decrease in cardiac contractility: Blood pressure↓・Heart rate↓・Cardiac output↓・Central venous pressure↑・Peripheral vascular resistance↑
(3) Abnormal blood distribution
① Septic warm shock (decrease in vascular resistance due to cytokines): Blood pressure↓・Heart rate↓・Cardiac output↑・Central venous pressure↓・Peripheral vascular resistance↓
②Septic cold shock (rupture of vascular endothelial cells): Blood pressure↓・Heart rate↓・Cardiac output↓・Central venous pressure↓・Peripheral vascular resistance↓
③ Anaphylaxis (increased vascular permeability): Blood pressure↓・Heart rate↓・Cardiac output→・Central venous pressure↑・Peripheral vascular resistance↓
Sympathetic blockade or vagal reflex: Blood pressure↓・Heart rate↑・Cardiac output→or↓・Central venous pressure↑・Peripheral vascular resistance↓
2. Indications for the “Risk for shock”
There are four categories of shock. Let’s follow the classification.
✩ Risk of hypocirculatory shock:
・Bleeding: Traffic injury, trauma, pelvic fracture, surgery, ectopic pregnancy, gastrointestinal bleeding, malignant tumor
・Dehydration: heat stroke, vomiting, diarrhea, hyperosmotic coma
・Vascular hyperpermeability: extensive burns, ileus, malnutrition, acute pancreatitis, general peritonitis
✩ Risk of cardiogenic shock:
・Myocardial damage (myocardial infarction, dilated cardiomyopathy, myocarditis, valvular disease, heart injury)
・Arrhythmia (same deficiency syndrome, Adams-Stokes syndrome, atrioventricular block, ventricular tachycardia, supraventricular tachycardia)
✩ Risk of extracardiac obstruction/restrictive shock:
Cardiovascular occlusion (pulmonary thromboembolism, acute arterial dissection, atrial myxoma)
・ Increased intrathoracic pressure (tension pneumothorax, positive pressure ventilation)
Cardiac compression (cardiac tamponade, constrictive pericarditis)
・Vascular compression (mediastinal tumor)
✩Risk of dysdistribution shock
Neurogenic (spinal cord injury, vasovagal reflex)
・Anaphylaxis (drugs, bees, food)
・Infectious disease (sepsis), immunocompromise (immunosuppressant, anticancer drug, leukopenia)
*The most common causes of sepsis are pneumonia, urinary tract infection, gastrointestinal perforation, cholecystitis, and cholangitis.
Acute renal failure (adrenal crisis)
3. setting a goal
Goal setting by linkage (listed in the second half of the NOC)
* “Linkage” has the role of connecting “NANDA”, “NIC” and “NOC” (link means “connection”).
1) Linkage achievements
Severity of shock: anaphylaxis (0417)
(Definition: severity of symptoms and signs suggestive of inadequate perfusion of tissue due to vasodilatation associated with acute onset of systemic hypersensitivity reactions and increased capillary permeability)
Severity of shock: Hypovolemia (0419)
(Definition: severity of symptoms and signs suggestive of inadequate blood status for tissue perfusion caused by severe intravascular volume depletion)
Severity of shock: neurogenic (0420)
(Definition: severity of symptoms and signs suggestive of inadequate blood status for tissue perfusion caused by persistent vasodilation due to sympathetic-parasympathetic imbalance)
Severity of shock: cardiogenic (0418)
(Definition: severity of symptoms and signs suggestive of inadequate blood flow to tissue perfusion caused by cardiac contraction and pump dysfunction)
Severity of shock: sepsis (0421)
(Definition: Severity of symptoms and signs suggestive of inadequate blood flow to tissue perfusion caused by vasodilation due to endotoxin production associated with widespread infection)
The goal is to make the patient the subject.
Instead of saying “Nurses can do ○○”,
For example, “The patient will be able to do ○○.”
・If you feel any abnormalities such as dizziness, palpitations, or discomfort, consult a medical professional.
・Able to follow the treatment plan and self-manage (internal medication, etc.).
*Nurse goals include:
・Early detection of abnormalities leads to early treatment.
・ Help patients adhere to treatment plans and prevent shock from occurring.
