Sepsis - Nursing Case Study

Pathophysiology

• Primary mechanism: Dysregulated host response to infection leads to widespread inflammation. This systemic inflammatory response results from immune cells releasing excessive cytokines, causing endothelial damage and increased vascular permeability.

• Secondary mechanism: Coagulation cascade activation contributes to microvascular thrombosis. The imbalance between pro-coagulant and anticoagulant pathways results in disseminated intravascular coagulation (DIC), further impairing tissue perfusion.

• Key complication: Multi-organ dysfunction syndrome (MODS) occurs as a critical complication due to persistent hypoperfusion and inflammation, leading to organ failure, often beginning with the lungs and kidneys.

Section 1

As the healthcare team continues to monitor the patient, new diagnostic results provide further insight into the progression of his condition. Laboratory findings reveal a significantly elevated white blood cell count of 18,000/mm³, indicative of an acute inflammatory response. Blood cultures confirm the presence of gram-negative bacteria, suggesting a likely source of infection that may have prompted the sepsis. Additionally, a lactic acid level of 4.5 mmol/L points to impaired tissue perfusion, a serious concern as it reflects worsening cellular oxygenation and impending metabolic derangement.

Renal function tests show a marked deterioration, with a creatinine level of 2.1 mg/dL and blood urea nitrogen (BUN) elevated at 45 mg/dL, confirming the onset of acute kidney injury. This renal impairment is consistent with the decreased urine output and hypotension observed in the initial assessment. The liver function tests also reveal elevated transaminases, suggesting hepatic involvement as part of the multi-organ dysfunction syndrome (MODS).

These results necessitate an urgent reassessment of the patient's management plan to address the underlying infection and support organ function. The healthcare team must consider adjusting antibiotic therapy based on the blood culture results, ensuring the selected antimicrobials are effective against the identified pathogen. In parallel, aggressive fluid resuscitation and vasopressor support may be required to stabilize hemodynamics and improve perfusion. These interventions are critical to curtail the cascade of complications and prevent further organ damage, setting the stage for the patient's continued care and monitoring.

Section 2

As the healthcare team implements the revised management plan, they focus on altering antibiotic therapy to target the identified gram-negative bacteria, opting for a broad-spectrum cephalosporin in combination with an aminoglycoside. Despite these adjustments, the patient exhibits a change in status within 24 hours of treatment initiation. He becomes increasingly tachycardic, with a heart rate climbing to 120 bpm, and his blood pressure remains unsteady, fluctuating between 85/50 mmHg and 90/55 mmHg despite fluid resuscitation efforts. The nurse notes that the patient's skin appears mottled, and capillary refill is delayed, now taking more than 3 seconds, indicating persistent peripheral hypoperfusion.

Furthermore, the patient's respiratory status deteriorates, requiring increased oxygen supplementation to maintain adequate saturation levels. Arterial blood gas analysis reveals a pH of 7.30, a partial pressure of carbon dioxide (PaCO2) of 50 mmHg, and a partial pressure of oxygen (PaO2) of 60 mmHg on a 50% oxygen mask, suggesting a mixed respiratory and metabolic acidosis. This development raises concern for respiratory compromise, potentially necessitating mechanical ventilation to support breathing and oxygenation.

The team also notes a slight increase in the patient's lactic acid level to 5.0 mmol/L, indicating that tissue hypoperfusion remains uncorrected. Renal function continues to decline, with creatinine increasing to 2.5 mg/dL, and urine output remains scant at less than 20 mL/hour. Given these new complications, the healthcare team must swiftly consider escalating vasopressor therapy, possibly starting norepinephrine, to improve systemic vascular resistance and stabilize blood pressure. The team is also prompted to consult with nephrology for potential renal replacement therapy to address the worsening kidney injury. These decisions are vital to mitigating the risk of further organ failure and to provide comprehensive support as the patient's condition evolves.

Section 3

As the healthcare team continues to monitor the patient's condition, they notice further changes in his clinical status. Despite the initiation of norepinephrine, the patient's blood pressure remains precarious, with readings barely reaching 95/60 mmHg. This inadequate response prompts the team to titrate the vasopressor dose upward cautiously. Concurrently, the patient's mental status begins to decline; he becomes increasingly lethargic and less responsive to verbal stimuli. His Glasgow Coma Scale score decreases to 10, indicating a significant alteration in his neurological status. These changes raise concerns about potential cerebral hypoperfusion or the development of sepsis-associated encephalopathy.

The healthcare team also receives new laboratory results that suggest additional complications. The patient's white blood cell count has increased to 18,000 cells/µL, indicating a persistent or worsening infection. His liver function tests reveal an elevation, with AST and ALT levels rising to 90 U/L and 95 U/L, respectively, suggesting hepatic involvement. The elevated bilirubin level of 3.0 mg/dL points to potential cholestasis or hepatic dysfunction, possibly secondary to sepsis or as a side effect of the antibiotic regimen. These findings necessitate a re-evaluation of the patient's current treatment strategy, with consideration of hepatoprotective measures and potential adjustment of antibiotic therapy.

In response to the ongoing deterioration, the multidisciplinary team decides to initiate renal replacement therapy to address the escalating renal failure and to assist in managing fluid overload. They also consult with an infectious disease specialist to assess the appropriateness of the current antimicrobial regimen, given the patient's lack of improvement and the risk of multi-organ dysfunction. The team remains vigilant, closely monitoring for signs of further complications, and prepares for potential escalation of care, including advanced respiratory support, should the patient's respiratory function continue to decline.

Section 4

As the healthcare team continues to manage the patient’s unstable condition, new diagnostic results reveal further complexities in his clinical picture. A follow-up chest X-ray shows signs of developing pulmonary edema, suggesting worsening fluid overload and impaired cardiac function, likely exacerbated by the ongoing sepsis and vasopressor therapy. In addition, an echocardiogram reveals a reduced left ventricular ejection fraction of 45%, pointing towards sepsis-induced cardiomyopathy as a contributing factor to the patient's hemodynamic instability.

Meanwhile, arterial blood gas analysis indicates a mixed metabolic and respiratory acidosis, with a pH of 7.28, PaCO2 of 50 mmHg, and HCO3 of 18 mEq/L. The metabolic component reflects the renal impairment and potential lactic acidosis secondary to tissue hypoperfusion, while the respiratory acidosis suggests developing respiratory compromise, possibly due to decreased mental status and inadequate ventilation. These findings prompt the team to consider implementing non-invasive positive pressure ventilation to support respiratory function and prevent further deterioration.

In light of the new results, the healthcare team intensifies their efforts to optimize hemodynamic support and organ function. They adjust the fluid management strategy to carefully balance fluid removal with the need to maintain adequate perfusion. The infectious disease consultant recommends broadening antimicrobial coverage to include agents targeting atypical pathogens, given the lack of clinical improvement. Additionally, hepatoprotective measures are initiated to address liver dysfunction, with close monitoring of liver enzymes and bilirubin levels. The team remains vigilant, ready to escalate respiratory support if the patient's status worsens, and continues to assess for other potential complications, such as disseminated intravascular coagulation or further neurological decline.

Section 5

As the healthcare team continues to closely monitor the patient, they observe a change in his status that indicates possible new complications. Over the next 12 hours, the patient exhibits increasing lethargy and confusion, which prompts a neurological assessment. His Glasgow Coma Scale (GCS) score has dropped from 14 to 10, suggesting a significant decline in neurological function. Concurrently, the patient's vital signs show persistent hypotension with blood pressures averaging 85/50 mmHg despite ongoing vasopressor support, and his heart rate remains elevated at 120 beats per minute. The team notes that his urine output has decreased to less than 20 mL/hour, raising concerns about acute kidney injury.

In light of these changes, the healthcare team orders additional laboratory tests and imaging studies to further explore the underlying causes of the patient's neurological deterioration and oliguria. A repeat arterial blood gas analysis reveals continued mixed acidosis with a slight worsening, showing a pH of 7.26, PaCO2 of 52 mmHg, and HCO3 of 17 mEq/L. Serum creatinine levels have increased to 2.5 mg/dL from a baseline of 1.2 mg/dL, confirming renal impairment. Furthermore, coagulation profiles indicate a prolonged prothrombin time (PT) and partial thromboplastin time (PTT), alongside a declining platelet count, suggesting the onset of disseminated intravascular coagulation (DIC).

These findings necessitate a reevaluation of the patient’s management plan. The team decides to initiate continuous renal replacement therapy (CRRT) to manage fluid overload and correct metabolic imbalances, while also adjusting the vasopressor regimen to optimize circulatory support. The potential for DIC is addressed with the administration of fresh frozen plasma and platelet transfusions, and the team remains vigilant for signs of bleeding. Given the patient's altered mental status, a CT scan of the head is ordered to rule out intracranial pathology, and neurology is consulted for further evaluation. The team continues to track the patient’s progress closely, recognizing the need for dynamic adjustments in treatment to address the evolving complexity of his condition.
