Liver Cirrhosis - Nursing Case Study
Pathophysiology
• Primary mechanism: Chronic liver injury, often due to factors like alcohol abuse or viral hepatitis, leads to continuous inflammation and hepatocyte damage. This results in the activation of hepatic stellate cells, which produce excessive collagen, causing fibrosis and the disruption of normal liver architecture.
• Secondary mechanism: The establishment of fibrotic bands and regenerative nodules impairs blood flow through the liver, leading to increased portal vein pressure (portal hypertension). This hypertension causes blood to bypass the liver, affecting detoxification and metabolism processes, and results in variceal formation and potential bleeding.
• Key complication: As liver function deteriorates, the impaired synthesis of proteins, such as albumin and clotting factors, contributes to ascites, coagulopathy, and susceptibility to infections, significantly impacting patient health and requiring careful nursing management.

Section 1
New Complications:
During the patient's hospital stay, he develops new complications indicative of worsening liver cirrhosis and portal hypertension. The nursing assessment reveals increased abdominal distension, suggesting worsening ascites, and the patient reports escalating discomfort. A focused neurological assessment shows that the patient's mild confusion has progressed to moderate hepatic encephalopathy, characterized by disorientation to time and place and asterixis (flapping tremor) during examination. The patient also exhibits signs of peripheral edema, which has worsened since admission, indicating further fluid retention and hypoalbuminemia.
Laboratory results reveal a declining liver function, with elevated bilirubin levels at 5.2 mg/dL, hypoalbuminemia with serum albumin at 2.8 g/dL, and prolonged prothrombin time (INR 2.1), all pointing towards compromised synthetic liver function. The complete blood count shows mild thrombocytopenia with a platelet count of 95,000/mm³, increasing the risk for bleeding. Additionally, a new abdominal ultrasound confirms splenomegaly and reveals the presence of esophageal varices, indicating significant portal hypertension.
These developments prompt the healthcare team to reevaluate the current treatment plan. The focus shifts to managing the complications associated with advanced liver disease, including increasing the dose of Lactulose to manage hepatic encephalopathy more effectively and considering the addition of spironolactone to better control ascites and edema. The team also discusses the need for an endoscopy to assess the severity of the esophageal varices and the potential for prophylactic treatment to prevent variceal bleeding. As the patient's condition evolves, continuous monitoring and adjustments to the care plan are crucial to mitigate risks and improve quality of life.

Change in Patient Status:
Despite the adjustments to the patient's treatment regimen, his condition continues to evolve, requiring vigilant monitoring and prompt intervention. Over the following days, the nursing team observes a further decline in his neurological status. The patient now exhibits more frequent episodes of confusion and lethargy, struggling to maintain alertness during interactions. His Glasgow Coma Scale (GCS) score has decreased to 12, indicating a moderate impairment in consciousness. The asterixis has become more pronounced, and he experiences difficulty in performing simple tasks, suggesting a progression of hepatic encephalopathy despite the increased Lactulose dosage.
Vital signs indicate a concerning trend in the patient's hemodynamic status. His blood pressure has dropped to 98/64 mmHg, coupled with an elevated heart rate of 112 beats per minute, signs that may be indicative of early hypovolemic shock due to significant fluid shifts and vasodilation associated with liver dysfunction. Additionally, his oxygen saturation on room air has decreased slightly to 92%, prompting consideration of supplemental oxygen to ensure adequate tissue perfusion.
Given these developments, the healthcare team contemplates the necessity for more aggressive therapeutic strategies. They consider the initiation of intravenous albumin to address the patient's hypoalbuminemia and support vascular volume. Furthermore, the worsening encephalopathy raises the question of whether additional treatments, such as Rifaximin, should be introduced to target the ammonia-producing gut flora more effectively. The possibility of intubation is also discussed in case the patient's respiratory status continues to decline. As the team navigates these challenges, they remain focused on tailoring the care plan to stabilize the patient and prevent further complications, keeping in mind the delicate balance between intervention and the underlying disease progression.
Section 3
New Complications:
In the days following the implementation of intravenous albumin therapy and the addition of Rifaximin, the healthcare team observes both expected improvements and concerning new developments in the patient's condition. While there is a slight stabilization in his blood pressure, now reading at 102/68 mmHg, and a modest reduction in heart rate to 104 beats per minute, the patient begins to exhibit signs of ascites. An increase in abdominal girth is noted, accompanied by a dull percussion sound on examination, suggesting fluid accumulation in the peritoneal cavity. This development raises the concern of portal hypertension and the potential for spontaneous bacterial peritonitis (SBP), a known complication in patients with advanced liver cirrhosis.
Laboratory tests reveal a further decline in serum albumin levels despite supplementation, now at 2.3 g/dL. Additionally, the patient's total bilirubin has risen to 5.6 mg/dL, indicating worsening liver function. A diagnostic paracentesis is performed to evaluate the ascitic fluid. The analysis shows an elevated white blood cell count with a predominance of neutrophils, suggesting a bacterial infection, thereby confirming the suspicion of SBP. The team initiates broad-spectrum antibiotics to combat the infection, monitoring the patient closely for any signs of sepsis.
As these complications unfold, the team remains vigilant in reassessing the patient's overall status, focusing on fluid balance and infection control. The multidisciplinary approach, including input from hepatology, infectious disease, and critical care specialists, is crucial in managing this complex case, as they strive to optimize the treatment plan and prevent further deterioration. The patient's journey reflects the intricate interplay between liver dysfunction and systemic complications, highlighting the need for ongoing critical reasoning and adaptive care strategies.

In the subsequent days, the patient's condition presents with new complications, prompting further evaluation by the healthcare team. Despite the initiation of antibiotics for spontaneous bacterial peritonitis (SBP), the patient begins to exhibit altered mental status, characterized by confusion and disorientation, raising the suspicion of hepatic encephalopathy. This change necessitates a thorough neurological assessment, which reveals asterixis, or "liver flap," further supporting the diagnosis. The healthcare team immediately adjusts the patient's lactulose regimen to enhance ammonia clearance, aiming to reduce neurotoxic effects and improve cognitive function.
Concurrently, laboratory results indicate a significant increase in serum creatinine, now at 2.1 mg/dL, signifying potential renal impairment, a complication often associated with hepatorenal syndrome (HRS) in the context of cirrhosis. The patient's urine output is also diminished, correlating with these findings and necessitating careful management of fluid status. Given the complex interplay between liver and kidney function, the team considers the use of vasoconstrictive agents and albumin to support renal perfusion and mitigate further decline.
Throughout this challenging period, the healthcare team remains attentive to the patient's evolving needs, balancing interventions to address both hepatic and renal concerns. The integration of clinical reasoning is crucial in evaluating the impact of therapeutic measures on the patient's overall trajectory, as they anticipate potential further deterioration or improvement. This dynamic situation requires constant vigilance and adaptability to optimize outcomes and prepare for the next phase of the patient's care journey.
Section 5
As the healthcare team implements adjustments to the patient's treatment plan, attention is closely paid to the response to interventions aimed at addressing the emerging complications. Over the following 48 hours, the patient's mental status shows signs of gradual improvement. The increased lactulose regimen successfully decreases serum ammonia levels, evidenced by laboratory results showing a reduction from 112 µmol/L to 75 µmol/L. This biochemical improvement is mirrored clinically as the patient begins to demonstrate clearer cognition and orientation. Despite these positive changes, asterixis is still intermittently present, indicating ongoing hepatic encephalopathy that requires continued monitoring and titration of treatment.
Concurrently, the patient's renal status remains a significant concern. Despite the administration of albumin and initiation of the vasoconstrictive agent terlipressin, serum creatinine levels plateau at 2.3 mg/dL, with no further significant increase but also no evident decline. Urine output is being closely monitored and remains marginal, averaging 400 mL over 24 hours, suggestive of oliguria. Blood pressure is stable at 108/72 mmHg, and heart rate is at 92 bpm, but there is a concern for fluid overload, as evidenced by mild peripheral edema and a weight gain of 1.5 kg over the past three days. These findings suggest a need for careful fluid balance management and potential adjustment in diuretic therapy, considering the risk of exacerbating renal impairment.
This evolving scenario presents a complex interplay between improving hepatic function and persistent renal challenges. The healthcare team must continue to employ clinical reasoning to balance the intricacies of treatment, ensuring that interventions for hepatic encephalopathy do not inadvertently worsen renal function. The team remains vigilant, anticipating the need for possible further interventions such as dialysis should the patient's renal status deteriorate despite current measures. The patient's condition requires ongoing reassessment, as the interplay between improving liver function and the precarious state of renal health continues to shape the clinical approach.
