Sepsis nursing management involves comprehensive care aimed at identifying, treating, and preventing complications associated with systemic infection and inflammation. Nurses play a vital role in early recognition, prompt intervention, and ongoing monitoring of patients at risk or diagnosed with sepsis. Here are key components of sepsis nursing management:
Pathophysiology of sepsis
Sepsis is a severe medical condition that arises when the body’s response to infection triggers a cascade of harmful systemic reactions. The pathophysiology of sepsis involves a complex interplay of immune, inflammatory, and coagulation responses:
- Infection: Sepsis typically begins with the invasion of pathogens, such as bacteria, viruses, fungi, or parasites, into the body through various routes, such as wounds, the respiratory tract, or the bloodstream.
- Immune Response: In response to the infection, the immune system activates a series of inflammatory pathways aimed at eliminating the invading pathogens. This involves the release of pro-inflammatory cytokines, such as tumor necrosis factor-alpha (TNF-alpha), interleukin-1 (IL-1), and interleukin-6 (IL-6), which stimulate immune cells and promote inflammation.
- Systemic Inflammation: While inflammation is a crucial defense mechanism, an exaggerated or dysregulated inflammatory response can lead to widespread inflammation throughout the body. This systemic inflammation can cause damage to tissues and organs, contributing to the development of sepsis.
- Endothelial Dysfunction: The inflammatory response can impair the function of the endothelial cells lining blood vessels, leading to increased vascular permeability and leakage of fluid and proteins into surrounding tissues. This endothelial dysfunction contributes to tissue edema and organ dysfunction.
- Coagulation Abnormalities: Sepsis can also disrupt the body’s normal blood clotting mechanisms, leading to a state of hypercoagulability and microvascular thrombosis. Concurrently, sepsis can also induce anticoagulant pathways, resulting in a paradoxical state of both clotting and bleeding tendencies.
- Organ Dysfunction: The combination of inflammation, endothelial dysfunction, and coagulation abnormalities can lead to impaired perfusion and oxygen delivery to vital organs, such as the lungs, kidneys, liver, and brain. This can result in multi-organ dysfunction syndrome (MODS), characterized by dysfunction or failure of two or more organ systems.
- Septic Shock: In severe cases of sepsis, profound hypotension may occur despite adequate fluid resuscitation, leading to septic shock. Septic shock is characterized by systemic hypoperfusion and organ failure, requiring aggressive treatment with vasopressor medications to maintain blood pressure and tissue perfusion.
Nursing problem priorities for patients with sepsis include:
- Early Recognition and Prompt Intervention: Rapid identification of sepsis symptoms and initiation of appropriate interventions are critical for improving patient outcomes and preventing progression to severe sepsis or septic shock.
- Hemodynamic Stability: Maintaining hemodynamic stability by closely monitoring vital signs, fluid status, and tissue perfusion is essential to prevent organ dysfunction and improve patient survival.
- Infection Control: Implementing strict infection control measures, such as hand hygiene, proper use of personal protective equipment, and isolation precautions, helps prevent the spread of infection and reduce the risk of healthcare-associated infections.
- Fluid Resuscitation: Administering intravenous fluids judiciously to restore intravascular volume and improve tissue perfusion while avoiding fluid overload and complications such as pulmonary edema or worsening organ dysfunction.
- Antibiotic Therapy: Administering appropriate broad-spectrum antibiotics promptly based on culture results and antimicrobial stewardship principles is crucial to target the underlying infection and prevent further microbial proliferation.
- Monitoring and Managing Organ Dysfunction: Regular assessment of organ function, including respiratory, cardiovascular, renal, and neurological systems, allows for early detection of organ dysfunction and prompt initiation of supportive therapies to prevent further deterioration.
- Pain Management: Providing adequate pain relief to alleviate discomfort and distress associated with sepsis and its treatment helps improve patient comfort and promote cooperation with therapeutic interventions.
- Nutritional Support: Ensuring adequate nutritional support tailored to individual patient needs helps maintain nutritional status, support immune function, and facilitate tissue repair and recovery.
- Psychological Support: Offering emotional support and reassurance to patients and their families helps alleviate anxiety, fear, and stress associated with sepsis diagnosis and treatment, promoting overall well-being and coping.
- Patient and Family Education: Providing comprehensive education on sepsis, its risk factors, signs and symptoms, treatment modalities, and strategies for preventing recurrence empowers patients and their families to actively participate in their care and promote positive outcomes.
Nursing assessment for patients with sepsis involves gathering both subjective and objective data:
Subjective Data:
- Reports of feeling flushed or having warm skin to the touch.
- Complaints of fever or increased body temperature beyond the normal range.
- Statements indicating difficulty breathing or an increased sensation of breathlessness.
- Verbalization of rapid heartbeat or palpitations.
- Patient’s perception of difficulty in following instructions or executing tasks, leading to the development of preventable complications.
- Questions, requests for information, or expressions of misunderstanding regarding their condition or treatment plan.
Objective Data:
- Observation of flushed skin, warmth to touch, and increased body temperature measured using a thermometer.
- Assessment of vital signs, including an elevated respiratory rate and tachycardia.
- Evaluation of respiratory effort, noting signs of increased work of breathing such as use of accessory muscles or nasal flaring.
- Monitoring for signs of confusion, altered mental status, or decreased level of consciousness.
- Assessment of skin perfusion and capillary refill time.
- Examination for signs of infection, such as localized tenderness, erythema, or purulent drainage at the site of infection.
- Assessment of fluid status, including input and output measurements, skin turgor, and mucous membrane moisture.
Factors related to the cause of sepsis include:
- Compromised immune system, such as in patients with HIV/AIDS, immunosuppressive therapy, or underlying chronic illnesses.
- Failure to recognize or treat infections promptly and appropriately, leading to systemic spread and sepsis.
- Invasive procedures or medical interventions that increase the risk of introducing pathogens into the body.
- Environmental exposure to nosocomial infections in healthcare settings.
- Reduction of arterial or venous blood flow due to vasoconstriction, vascular occlusion, or microemboli, impairing tissue perfusion.
- Relative or actual hypovolemia resulting from fluid losses, inadequate fluid intake, or third-spacing of fluids.
- Altered oxygen supply due to respiratory alkalosis from hyperventilation induced by endotoxins, or hypoventilation due to respiratory compromise.
Nursing goals and expected outcomes for patients with sepsis may include:
- The patient will achieve timely wound healing, with no evidence of purulent secretions, drainage, or erythema, and absence of fever.
- The patient will demonstrate adequate tissue perfusion, as indicated by stable vital signs, palpable peripheral pulses, warm and dry skin, normal mental status, appropriate urinary output, and active bowel sounds.
- The patient’s arterial blood gases (ABGs) and respiratory rate will be within normal range, with clear breath sounds and improvement or clearance of abnormalities on chest x-ray.
Nursing Implementation
Therapeutic interventions and nursing actions for patients with sepsis may include:
- Initiating Infection Control and Prevention Patients with sepsis are vulnerable to infections due to compromised immune function and tissue damage caused by systemic inflammation. Prompt identification and isolation of the infection source are crucial for guiding antimicrobial therapy and preventing further spread of infection. Strict infection control measures in healthcare settings are essential for reducing the risk of hospital-acquired infections.
- Assess the patient for signs of infection, such as burning urination, abdominal pain, open wounds, or presence of invasive catheters. Common sources of sepsis include respiratory and urinary tract infections, abdominal issues, and catheter-related infections. Clinical assessment helps identify potential sources of infection, guiding appropriate diagnostic and treatment interventions.
- Investigate reports of disproportionate pain compared to visible signs of infection. Severe pain over an area of cellulitis may indicate necrotizing fasciitis, requiring urgent intervention. Abdominal pain may suggest underlying issues like pancreatitis or peritonitis, requiring prompt assessment and treatment.
- Regularly inspect wounds and invasive device sites for signs of inflammation or infection, and document any changes in wound drainage or appearance. Close monitoring of wounds and catheter sites helps detect early signs of infection, facilitating timely intervention to prevent systemic spread of infection. Catheter-related bloodstream infections are common in septic patients and require prompt identification and management.
- Assess the oral cavity for white plaques and investigate reports of vaginal or perineal itching or burning. Patients with compromised immune systems are prone to secondary infections, such as oral thrush or vaginal yeast infections. Early detection and treatment of these infections help prevent complications and aid in overall recovery.
- Monitor temperature trends and observe for shaking chills and profuse sweating. Fever and chills are common manifestations of sepsis, reflecting the body’s response to infection. Hypothermia may indicate severe sepsis and poor tissue perfusion, necessitating immediate intervention. Regular temperature monitoring helps in assessing the patient’s response to treatment and identifying any worsening of the condition.
Preventing Shock:
Sepsis can progress to systemic inflammatory response syndrome and septic shock, a life-threatening condition characterized by persistent hypotension despite adequate fluid resuscitation. Prompt recognition and intervention are crucial to prevent or treat septic shock.
- Monitor blood pressure trends, especially noting progressive hypotension and widening pulse pressure. Hypotension in sepsis results from systemic vasodilation and decreased systemic vascular resistance. As shock progresses, cardiac output decreases, leading to profound hypotension.
- Monitor heart rate and rhythm for tachycardia and dysrhythmias. Tachycardia compensates for hypovolemia and reduced cardiac output in response to stress. Dysrhythmias may occur due to hypoxia, acid-base imbalance, or low-flow perfusion.
- Assess peripheral pulses for quality and strength. Initially strong and bounding, pulses may become weak due to sustained hypotension and decreased cardiac output if shock progresses.
- Evaluate respiratory rate, depth, and quality for signs of dyspnea. Tachypnea develops in response to endotoxins affecting the respiratory center and hypoxia. Shallow respirations indicate respiratory insufficiency and the risk of acute respiratory failure.
- Assess skin for color, temperature, and moisture changes. Vasodilation initially results in warm, dry, pink skin. Progression to shock causes vasoconstriction and cool, clammy, pale, or dusky skin, indicating poor tissue perfusion.
- Monitor changes in sensorium for signs of altered mental status. Confusion, lethargy, or coma indicate cerebral perfusion alterations and are associated with increased mortality in septic shock.
- Auscultate bowel sounds for signs of decreased peristalsis. Splanchnic vasoconstriction reduces mesenteric blood flow, leading to paralytic ileus, a common complication of septic shock.
- Measure hourly urine output and record urine specific gravity. Decreasing urine output and high specific gravity indicate renal hypoperfusion. Oliguria may progress from transient polyuria during the hyperdynamic phase.
- Test gastric secretions and stools for occult blood. Sepsis-related stress and steroid use increase the risk of gastric mucosal erosion and bleeding, contributing to complications.
Enhancing Gas Exchange and Breathing Pattern
In sepsis, inflammatory mediators can damage the alveoli and cause capillary leakage in the lungs, impairing gas exchange. This can lead to hypoxemia, respiratory distress, and organ failure. Enhancing gas exchange and optimizing breathing patterns in septic patients is crucial to prevent complications. Interventions include oxygen therapy, mechanical ventilation if needed, and strategies to promote optimal breathing patterns, such as deep breathing exercises and positioning.
- Monitor respiratory rate and depth, and assess for the use of accessory muscles. Rapid, shallow breathing due to hypoxemia, stress, and endotoxins is common in sepsis. Hypoventilation and dyspnea indicate ineffective compensation and may necessitate ventilatory support. Hyperventilation with respiratory alkalosis can also occur due to endotoxin stimulation of the medullary respiratory center.
- Auscultate breath sounds for crackles, stridor, wheezes, and changes in ventilation. Respiratory distress and adventitious sounds suggest atelectasis, interstitial edema, and pulmonary congestion. Injury to lung endothelial and epithelial cells increases alveolar capillary permeability, leading to alveolar edema.
- Assess for changes in mental status, including confusion, lethargy, and coma. Cerebral function is sensitive to decreased oxygenation and perfusion. Altered mental status is common in sepsis and is associated with increased mortality. Profound cases may involve coma. Altered amino acid metabolism may contribute to cerebral hypoperfusion.
