Study Notes
Immunosuppression and Chronic Illness
- Immunosuppression increases the risk of infections, including bacteremia, pneumonia, and urosepsis.
- Chronic illnesses can compromise immune responses, making patients more vulnerable to severe complications.
Invasive Procedures and Septic Shock
- Invasive procedures should utilize strict aseptic techniques to prevent infection.
- Septic shock results from the activation of a biochemical cascade involving cytokines and other mediators.
- A significant immune response leads to decreased tissue perfusion and can result in multi-organ failure.
Physiological Changes
- Increased heart rate and contractility (catecholamines) are responses to maintain cardiac output during shock.
- Blood shunting redirects blood flow away from less vital organs (e.g., kidneys, gastrointestinal tract) to preserve function in vital organs.
Compensatory Stage of Shock
- Metabolic acidosis often occurs due to lactic acid buildup.
- Respiratory alkalosis may occur as the body attempts to expel carbon dioxide.
- Key clinical signs include increased respiratory rate, normal blood pressure, increased heart rate, and cold, clammy skin.
Nursing and Medical Management
- Systematic assessment of patients is essential for identifying underlying causes of shock.
- Administer IV fluids and oxygen to support patient recovery.
- Monitor laboratory results to assess metabolic status and infection.
Monitoring Tissue Perfusion
- Continuous monitoring of vital signs, urine output, skin condition, respiratory rate, and laboratory values is crucial.
- Serum sodium and blood glucose levels should be monitored, especially during infection.
- Systolic blood pressure below 90 mmHg or mean arterial pressure below 65 mmHg signals significant concern.
Management Interventions
- Focus on reducing tissue oxygen requirements and increasing perfusion.
- Use sedation and IV opioids to manage pain and reduce cardiac workload.
- Provide IV fluids and medications to support hemodynamic stability.
Reducing Patient Anxiety
- Educate patients and families about processes and care to alleviate anxiety.
- Gentle communication, frequent reorientation, and fall prevention strategies are important in patient care.
Progressive Stage of Shock
- In the progressive stage, compensatory mechanisms can fail, leading to hypotension and declining blood pressure.
- Monitoring and intervention become critical to prevent further deterioration.
