gi bleed - Nursing Case Study

Pathophysiology

• Primary mechanism: Mucosal erosion or ulceration in the gastrointestinal tract, often due to peptic ulcer disease or NSAID use, disrupts the protective lining, leading to blood vessel exposure and bleeding.

• Secondary mechanism: Variceal bleeding, commonly from esophageal varices due to portal hypertension in liver cirrhosis, results in increased pressure in venous structures, causing them to rupture and bleed.

• Key complication: Hemodynamic instability from significant blood loss can lead to hypovolemic shock, requiring urgent fluid resuscitation and stabilization to prevent organ failure.

Section 1

As the nursing team conducts an initial assessment, it becomes evident that the patient's condition is precarious. The skin appears pale and cool to the touch, with capillary refill delayed to more than 3 seconds, indicating potential hypoperfusion. Auscultation of the abdomen reveals hypoactive bowel sounds, and the patient reports a cramping sensation alongside his persistent nausea. Upon further questioning, he admits to using ibuprofen intermittently for joint pain, which may have exacerbated his peptic ulcer disease, leading to the current bleeding episode.

Emergent laboratory results return, showing a hemoglobin level of 7.4 g/dL, significantly lower than the normal range, and a hematocrit of 22%, indicating substantial blood loss. The blood urea nitrogen (BUN) is elevated at 35 mg/dL, possibly due to absorption of blood in the gastrointestinal tract. These findings suggest an urgent need for blood transfusion to stabilize the patient and prevent further decline. The elevated heart rate and low blood pressure indicate a compensatory mechanism for hypovolemia, necessitating immediate intervention.

Despite initial fluid resuscitation efforts, the patient's blood pressure remains at 90/58 mmHg with a heart rate of 120 bpm, suggesting persistent hemodynamic instability. The team prepares for potential endoscopic intervention to identify and address the bleeding source, considering both medication management to protect the gastric mucosa and the potential need for surgical consultation. The patient's continued dizziness and fatigue raise concerns for ongoing blood loss, warranting close monitoring for signs of hypovolemic shock and further deterioration. This situation calls for vigilant assessment and prompt escalation of care to prevent organ dysfunction and improve patient outcomes.

Section 2

As the team continues to address the patient's condition, a new set of diagnostic results arrives, offering crucial insights into his evolving clinical picture. The repeat complete blood count (CBC) shows a further drop in hemoglobin to 6.8 g/dL, underscoring the urgency of initiating a blood transfusion to mitigate the risks of profound anemia and its associated complications. The coagulation profile reveals a prolonged prothrombin time (PT) and activated partial thromboplastin time (aPTT), suggesting a possible coagulopathy that could exacerbate the bleeding. These findings prompt the team to consider the administration of fresh frozen plasma along with packed red blood cells to correct the coagulopathy and stabilize the patient hemodynamically.

In addition to these laboratory results, the team's vigilant monitoring detects a change in the patient's neurological status. He appears increasingly lethargic and his responses to verbal stimuli are delayed, raising concerns about cerebral hypoperfusion due to inadequate oxygen delivery. The patient's blood pressure remains precariously low at 88/55 mmHg, despite the bolus fluids administered earlier, further hinting at the potential for multi-organ dysfunction if the bleeding source is not swiftly controlled. Continuous telemetry monitoring shows sinus tachycardia with occasional premature ventricular contractions, suggesting ongoing cardiac strain from hypovolemia.

Given the new diagnostic insights and the patient's deteriorating status, the multidisciplinary team convenes to prioritize endoscopic evaluation and intervention. The gastroenterology team prepares for an urgent endoscopy to locate and manage the bleeding site, while the surgical team remains on standby for potential escalation to operative intervention if endoscopy proves insufficient. This strategic approach, coupled with aggressive transfusion therapy and close observation, aims to arrest the bleeding, restore hemodynamic stability, and prevent further complications such as acute renal injury or acute respiratory distress syndrome. The focus remains on timely intervention and comprehensive care to navigate this critical phase in the patient's journey.

Section 3

As the urgent endoscopy proceeds, the team uncovers a large duodenal ulcer actively bleeding, confirming the source of the gastrointestinal hemorrhage. The gastroenterologist successfully achieves hemostasis using endoscopic clips and cauterization, temporarily stabilizing the bleeding. However, the team remains vigilant, knowing that the risk of rebleeding is a concern, especially in the context of the patient's underlying coagulopathy. Post-procedure, the patient is closely monitored in the intensive care unit, where his vital signs show slight improvement. His blood pressure stabilizes at 95/60 mmHg, and heart rate reduces to 110 beats per minute, indicating a positive response to the combined interventions of endoscopic management and aggressive transfusion therapy.

Despite these improvements, the patient exhibits signs of acute kidney injury (AKI), likely precipitated by prolonged hypotension and hypoperfusion. His serum creatinine levels have elevated from a baseline of 1.0 mg/dL to 2.5 mg/dL, and urine output has decreased to less than 0.5 mL/kg/hr over the last six hours. This development necessitates nephrology consultation to assess the need for renal replacement therapy and to guide fluid management strategies that balance renal perfusion against the risk of worsening cardiac strain and pulmonary edema.

The patient's neurological status also remains a critical concern. While slightly more responsive post-transfusion, he continues to demonstrate altered mental status with intermittent confusion, suggesting ongoing cerebral hypoperfusion or potential sequelae of the initial hypoxic insult. A head CT is ordered to rule out any acute intracranial pathology, and the team considers the need for further neurological evaluation. The focus shifts towards optimizing cerebral perfusion and preventing further deterioration while addressing the evolving renal complications. As the patient navigates this critical juncture, the multidisciplinary team remains committed to comprehensive, dynamic care, ready to adapt their strategies to the complexities of his condition.

Section 4

As the patient remains under close observation in the intensive care unit, new diagnostic results reveal further insights into his condition. The head CT scan returns negative for any acute intracranial events, providing some reassurance that there are no immediate structural causes for his altered mental status. However, laboratory results indicate a concerning trend in his coagulation profile, with an INR of 2.5 and a platelet count of 90,000/µL, underscoring the ongoing risk of rebleeding from the duodenal ulcer. In light of his coagulopathy, the team decides to administer fresh frozen plasma and platelet transfusions cautiously, balancing the need to correct his coagulation status with the risk of volume overload.

Meanwhile, the nephrology team reviews the patient’s renal function and concurs with the critical care team's assessment of acute kidney injury. They recommend initiating a conservative fluid management strategy with isotonic crystalloids to optimize renal perfusion while avoiding fluid overload. Additionally, a low-dose diuretic regimen is considered to enhance urine output and prevent further fluid retention, given the patient's marginal cardiac function. The nephrologists emphasize the importance of closely monitoring electrolyte levels, particularly potassium and magnesium, to prevent arrhythmias and further complications.

As the day progresses, the patient's response to these interventions is mixed. His urine output begins to improve modestly, rising to 0.7 mL/kg/hr, suggesting a positive renal response. However, his mental status remains inconsistent, with occasional episodes of restlessness and disorientation. The critical care team remains vigilant, recognizing the need for ongoing assessment and potential adjustments in his management plan. They prepare for the possibility of continuous renal replacement therapy should his renal function further deteriorate. The next steps involve frequent reassessment of his neurological and renal status, with a focus on preventing further complications and stabilizing his condition.

Section 5

As the intensive care unit team conducts their routine checks, a noticeable change in the patient's status prompts immediate attention. The patient's heart rate has climbed to 115 beats per minute, and his blood pressure has dropped to 88/56 mmHg, indicating possible hemodynamic instability. His respiratory rate is slightly elevated at 22 breaths per minute, and oxygen saturation has dipped to 91% on room air, necessitating supplemental oxygen. These changes raise concerns about potential hypovolemic shock due to ongoing gastrointestinal bleeding.

In response to these alarming signs, the critical care team initiates a rapid assessment of the patient's volume status. Despite the previous cautious approach to fluid management, the team decides to increase isotonic crystalloid infusion to support intravascular volume. Concurrently, they reevaluate the need for blood products, considering a packed red blood cell transfusion to improve oxygen delivery and tissue perfusion. The team also orders a repeat hemoglobin and hematocrit test, which reveals a further drop to 7.2 g/dL and 21%, respectively, confirming significant blood loss.

As this crisis unfolds, the team also contemplates the integration of vasopressors to stabilize blood pressure, given the patient's inadequate response to fluid resuscitation. This decision necessitates a delicate balance, as aggressive vasopressor use could compromise renal perfusion. The team prioritizes continuous hemodynamic monitoring, carefully titrating interventions to prevent further complications. This dynamic situation underscores the importance of interdisciplinary collaboration, with the critical care, nephrology, and gastroenterology teams working in concert to address the multifaceted challenges posed by the patient's evolving condition. As they navigate these complexities, the focus remains on stabilizing the patient and preventing progression to more severe complications.
