Sepsis is a life-threatening condition that occurs when the body’s response to infection causes widespread inflammation, potentially leading to organ failure and death. As a critical care emergency, sepsis requires prompt recognition, assessment, and intervention by healthcare professionals, particularly nurses, who are often at the frontline of patient care.
Understanding Sepsis
Sepsis is defined as a dysregulated host response to infection that leads to life-threatening organ dysfunction. It can progress rapidly from sepsis to severe sepsis and ultimately to septic shock, which is associated with a high mortality rate.
Stages of Sepsis
Sepsis: Suspected or confirmed infection with at least two of the following criteria:
- Temperature > 38°C (100.4°F) or < 36°C (96.8°F)
- Heart rate > 90 beats/minute
- Respiratory rate > 20 breaths/minute
- White blood cell count > 12,000/mm³ or < 4,000/mm³
- Severe Sepsis: Sepsis plus organ dysfunction, which may include:
- Hypotension
- Elevated lactate levels
- Decreased urine output
- Acute lung injury
- Coagulation abnormalities
- Thrombocytopenia
- Hyperbilirubinemia
Septic Shock: Severe sepsis with persistent hypotension despite adequate fluid resuscitation, often requiring vasopressors to maintain mean arterial pressure ≥ 65 mmHg.
Nursing Process for Sepsis
Assessment
The nursing assessment for sepsis involves a comprehensive evaluation of the patient’s condition, including:
Vital Signs Monitoring:
- Temperature
- Heart rate
- Respiratory rate
- Blood pressure
- Oxygen saturation
Physical Examination:
- Skin color and temperature
- Capillary refill time
- Mental status
- Urine output
- Presence of edema
Laboratory Tests:
- Complete blood count (CBC)
- Blood cultures
- Lactate levels
- Procalcitonin
- Coagulation studies
- Arterial blood gases
- Comprehensive metabolic panel
Imaging Studies:
- Chest X-ray
- CT scans (as indicated)
Source Identification:
- Assess for potential sources of infection (e.g., wounds, indwelling catheters, recent surgeries)
Nursing Diagnoses
Based on the assessment findings, nurses can formulate appropriate nursing diagnoses. Common nursing diagnoses for patients with sepsis include:
- Ineffective Tissue Perfusion
- Hyperthermia
- Risk for Shock
- Acute Confusion
- Impaired Gas Exchange
Planning and Implementation
The planning and implementation phase involves developing and executing a care plan based on the identified nursing diagnoses. This includes setting goals, determining interventions, and implementing those interventions.
Evaluation
Continuous evaluation of the patient’s response to interventions is crucial in sepsis management. Nurses should regularly reassess the patient’s condition and adjust the care plan.
Nursing Care Plans for Sepsis
Here are five detailed nursing care plans for patients with sepsis:
Nursing Care Plan 1: Ineffective Tissue Perfusion
Ineffective Tissue Perfusion related to Sepsis-Induced Circulatory Changes
Nursing Diagnosis Statement: Ineffective Tissue Perfusion related to sepsis-induced circulatory changes as evidenced by decreased peripheral pulses, altered skin color, and prolonged capillary refill time.
Related factors/causes:
- Inflammatory response in sepsis
- Microcirculatory dysfunction
- Vasodilation and increased vascular permeability
- Myocardial depression
Nursing Interventions and Rationales:
- Monitor vital signs, especially blood pressure and heart rate, every 1-2 hours or as needed.
Rationale: Frequent monitoring allows for early detection of deterioration and prompt intervention. - Assess peripheral circulation (capillary refill, skin color, temperature) every 2-4 hours.
Rationale: Changes in peripheral circulation can indicate worsening tissue perfusion. - Administer intravenous fluids as prescribed, monitoring for signs of fluid overload.
Rationale: Fluid resuscitation is crucial in sepsis to improve tissue perfusion, but careful monitoring is necessary to prevent complications. - Position the patient with the head of the bed elevated at 30-45 degrees unless contraindicated.
Rationale: This position can improve oxygenation and reduce the risk of aspiration. - Vasopressors should be administered as prescribed, and blood pressure response should be closely monitored.
Rationale: Vasopressors may be necessary to maintain adequate perfusion pressure in septic shock.
Desired Outcomes:
- The patient will demonstrate improved tissue perfusion as evidenced by:
- Normalized vital signs within 24-48 hours
- Warm and pink extremities
- Capillary refill time < 3 seconds
- Adequate urine output (> 0.5 mL/kg/hour)
Nursing Care Plan 2: Hyperthermia
Hyperthermia related to Systemic Inflammatory Response
Nursing Diagnosis Statement: Hyperthermia related to systemic inflammatory response as evidenced by elevated body temperature, flushed skin, and tachycardia.
Related factors/causes:
- Infection-induced inflammatory response
- Release of pyrogens
- Increased metabolic rate
Nursing Interventions and Rationales:
- Monitor body temperature every 2-4 hours or continuously if possible.
Rationale: Frequent monitoring allows for tracking of fever trends and the effectiveness of interventions. - Administer antipyretics as prescribed (e.g., acetaminophen).
Rationale: Antipyretics can help reduce fever and improve patient comfort. - Apply cooling measures as appropriate (e.g., cool compresses, cooling blanket).
Rationale: External cooling can help reduce body temperature when combined with antipyretics. - Encourage oral fluids if the patient is alert and able to swallow safely.
Rationale: Increased fluid intake helps prevent dehydration associated with fever. - Monitor for signs of shivering and discontinue cooling measures if shivering occurs.
Rationale: Shivering can increase metabolic rate and potentially worsen fever.
Desired Outcomes:
- The patient will maintain a normal body temperature (36.5°C – 37.5°C) within 24 hours.
- The patient will report improved comfort related to fever reduction.
Nursing Care Plan 3: Risk of Shock
Risk for Shock related to Severe Inflammatory Response and Cardiovascular Compromise
Nursing Diagnosis Statement: Risk for Shock related to severe inflammatory response and cardiovascular compromise secondary to sepsis.
Related factors/causes:
- Systemic vasodilation
- Increased capillary permeability
- Myocardial depression
- Hypovolemia
Nursing Interventions and Rationales:
- Monitor vital signs, including mean arterial pressure (MAP), every 15-30 minutes or continuously.
Rationale: Early detection of hypotension allows for prompt intervention to prevent shock. - Assess for signs of shock (e.g., altered mental status, oliguria, cold extremities) every 1-2 hours.
Rationale: Regular assessment can identify early signs of shock before severe organ dysfunction occurs. - Administer intravenous fluids as prescribed, closely monitoring for signs of fluid overload.
Rationale: Fluid resuscitation is crucial in preventing and treating septic shock, but careful monitoring is necessary. - Prepare for and assist with central venous catheter insertion if ordered.
Rationale: Central venous access allows for more accurate hemodynamic monitoring and administration of vasopressors. - Vasopressors should be administered as prescribed, and titrating should be done to maintain MAP ≥ 65 mmHg.
Rationale: Vasopressors are often necessary to maintain adequate perfusion pressure in septic shock.
Desired Outcomes:
- The patient will maintain adequate tissue perfusion as evidenced by:
- MAP ≥ 65 mmHg
- Urine output > 0.5 mL/kg/hour
- Improved mental status
- Warm extremities with good capillary refill
Nursing Care Plan 4: Acute confusion
Acute Confusion related to Sepsis-Induced Cerebral Hypoperfusion
Nursing Diagnosis Statement: Acute Confusion related to sepsis-induced cerebral hypoperfusion as evidenced by fluctuating level of consciousness, disorientation, and agitation.
Related factors/causes:
- Cerebral hypoperfusion
- Metabolic disturbances
- Hypoxemia
- Medication side effects
Nursing Interventions and Rationales:
- Assess the level of consciousness and orientation every 2-4 hours using a standardized tool (e.g., Glasgow Coma Scale).
Rationale: Regular assessment allows for early detection of changes in mental status. - Implement safety measures (e.g., bed alarms, frequent checks) to prevent falls or self-harm.
Rationale: Confused patients are at higher risk for accidents and injuries. - Provide a calm, well-lit environment with familiar objects if possible.
Rationale: A soothing environment can help reduce agitation and promote orientation. - Reorient the patient frequently to person, place, and time.
Rationale: Regular reorientation can help improve cognitive function and reduce confusion. - Involve family members in care and encourage their presence if appropriate.
Rationale: Familiar faces and voices can help comfort and orient the patient.
Desired Outcomes:
- The patient will demonstrate improved cognitive function within 48-72 hours as evidenced by:
- Increased alertness and orientation
- Appropriate responses to questions and commands
- Decreased agitation
Nursing Care Plan 5: Impaired Gas Exchange
Impaired Gas Exchange related to Acute Respiratory Distress Syndrome (ARDS) Secondary to Sepsis
Nursing Diagnosis Statement: Impaired Gas Exchange related to Acute Respiratory Distress Syndrome (ARDS) secondary to sepsis as evidenced by hypoxemia, tachypnea, and decreased oxygen saturation.
Related factors/causes:
- Inflammation-induced alveolar damage
- Pulmonary edema
- Ventilation-perfusion mismatch
Nursing Interventions and Rationales:
- Monitor respiratory rate, depth, and work of breathing every 1-2 hours or continuously.
Rationale: Close monitoring allows for early detection of respiratory deterioration. - Assess oxygen saturation continuously via pulse oximetry and obtain arterial blood gases as ordered.
Rationale: These measures provide crucial information about oxygenation and ventilation status. - Position the patient in a semi-Fowler’s or high Fowler’s position unless contraindicated.
Rationale: Upright positioning can improve lung expansion and oxygenation. - Administer oxygen therapy as prescribed, titrating to maintain SpO2 > 90% or as ordered.
Rationale: Supplemental oxygen helps correct hypoxemia and reduce work of breathing. - Prepare for and assist with intubation and mechanical ventilation if necessary.
Rationale: Severe ARDS may require invasive ventilatory support to maintain adequate oxygenation.
Desired Outcomes:
- The patient will demonstrate improved gas exchange within 24-48 hours as evidenced by:
- Respiratory rate within normal limits (12-20 breaths/minute)
- SpO2 > 92% on prescribed oxygen therapy
- Arterial blood gas values within acceptable ranges
- Decreased work of breathing
Conclusion
Sepsis is a complex and life-threatening condition that requires prompt recognition and intervention. Nurses play a crucial role in the early identification, ongoing assessment, and management of patients with sepsis. By implementing evidence-based nursing care plans and interventions, healthcare professionals can significantly improve outcomes for patients with sepsis.
