54 year old male with ischemic stroke on TPA - Nursing Case Study

Pathophysiology

• Primary mechanism: Ischemic stroke in this patient results from an obstruction in cerebral blood flow, often due to a thrombus or embolus occluding a cerebral artery. This obstruction leads to a critical reduction in oxygen and nutrient delivery to brain tissue, causing cellular injury and death.

• Secondary mechanism: The administration of Tissue Plasminogen Activator (tPA) aims to restore perfusion by enzymatically converting plasminogen to plasmin, which then breaks down fibrin clots. Timely administration is crucial to salvage the ischemic penumbra, the area surrounding the core infarct that is at risk but potentially reversible.

• Key complication: Hemorrhagic transformation is a major severe complication of tPA therapy, where reperfusion leads to vessel rupture in weakened brain tissue. This can exacerbate neurological deficits and increase mortality, highlighting the need for careful monitoring and patient selection.

• Vital signs: Blood Pressure 200/110 mmHg, Heart Rate 122 bpm, Respiratory Rate 24 breaths per minute, Temperature 99.1°F, Oxygen Saturation 88% on room air

Section 1

As the patient is stabilized in the intensive care unit following the administration of tPA, his condition demands vigilant monitoring. Initial assessment findings after tPA administration reveal a transient improvement in speech and a slight reduction in right-sided weakness, suggesting partial reperfusion. However, new diagnostic results, including a follow-up CT scan, indicate a worrying development: an area of contrast enhancement in the left hemisphere, raising suspicion for hemorrhagic transformation. The patient’s neurological status fluctuates; he becomes increasingly lethargic, and his GCS score drops from 14 to 10, indicating a deterioration in consciousness.

Vital signs reflect an unstable state; blood pressure remains elevated at 190/100 mmHg despite antihypertensive therapy, and oxygen saturation is persistently low at 85% on 3L of oxygen via nasal cannula, suggesting impaired respiratory function, potentially from aspiration or neurogenic pulmonary edema. Laboratory tests reveal worsening hyperglycemia with a blood glucose level of 320 mg/dL and an INR of 1.3, underscoring the importance of managing comorbid conditions that can exacerbate cerebral edema and bleeding risk.

These findings necessitate a rapid and coordinated clinical response. The interdisciplinary team contemplates potential interventions, including the escalation of antihypertensive strategies, consideration for intubation to secure the airway and optimize oxygenation, and the cautious use of osmotic therapy to mitigate cerebral edema. The treatment plan must balance the risks of further bleeding against the need for aggressive management of secondary insults. The evolving nature of the patient's condition underscores the need for frequent reassessment and adjustment of the therapeutic approach, illustrating the complexity and criticality of care in ischemic stroke complicated by hemorrhagic transformation.

Section 2

As the interdisciplinary team moves swiftly to address the critical situation, the patient's condition takes another concerning turn. Despite adjustments to the antihypertensive regimen, including the initiation of a continuous intravenous nicardipine infusion, the patient's blood pressure remains stubbornly high at 180/95 mmHg. The persistence of hypertension exacerbates concerns about the risk of further hemorrhagic transformation. Meanwhile, the decision to intubate is made as the patient's oxygen saturation drops to 82%, even with increased oxygen delivery. The intubation process is complicated by his diminished consciousness, and the team must proceed with caution to prevent additional stress or injury.

Shortly after intubation, the patient exhibits signs of increased intracranial pressure (ICP), evidenced by a widening pulse pressure and bradycardia, with heart rate dropping to 50 beats per minute. An urgent repeat CT scan reveals an increase in midline shift and a new area of hemorrhage in the temporal lobe, confirming the feared complication of expanding hemorrhagic transformation. The lab results return showing a further rise in blood glucose levels to 360 mg/dL, complicating the metabolic picture and potentially worsening cerebral edema. The team initiates osmotic therapy with mannitol, carefully weighing the benefits against the potential for worsening intracerebral bleeding.

The patient's family, gathered in the waiting room, is briefed on the severity of the situation. The family meeting highlights the critical need for ongoing intensive monitoring and the possibility of surgical intervention if the patient's condition deteriorates further. The team emphasizes the importance of maintaining cerebral perfusion pressure while minimizing additional bleeding risks, a delicate balance that requires constant vigilance and adaptability in the evolving landscape of this complex case. As the situation unfolds, the team remains acutely aware of the need for frequent reassessment and the potential for rapid changes in the patient's status, necessitating immediate and informed clinical decisions.

Section 3

As the team continues to manage the patient's precarious condition, a change in status becomes apparent. The patient’s neurological exam reveals a further decline in responsiveness, with pupils now unequal, the left being 5 mm and sluggishly reactive, while the right is 3 mm and brisk. This asymmetry suggests worsening cerebral edema and potentially increasing intracranial pressure. Despite the administration of mannitol, the patient’s ICP remains elevated, prompting the team to consider additional measures to control cerebral swelling. The decision is made to initiate hypertonic saline infusion, aiming to aggressively manage the swelling while monitoring for any electrolyte imbalances.

Meanwhile, the patient's hemodynamic status also shows signs of instability. While the nicardipine infusion continues, blood pressure remains elevated at 175/92 mmHg, and the heart rate has decreased further to 48 beats per minute. The potential for Cushing's triad becomes a concern, indicating increasing ICP and possible brain herniation. The team discusses the possibility of surgical decompression as a last resort, understanding the risks involved given the recent hemorrhagic transformation.

In parallel, new lab results reveal worsening hyperglycemia, with blood glucose levels now climbing to 400 mg/dL. The endocrinology consult recommends starting an insulin drip to bring glucose levels under control, recognizing the potential impact of hyperglycemia on worsening cerebral edema and poor neurological outcomes. As these interventions are implemented, the team prepares for the possibility of immediate surgical intervention, maintaining open communication with the neurosurgical team and the patient’s family regarding the potential need for more aggressive measures. The complexity of the case necessitates constant reassessment, with the team poised to act swiftly in response to any further deterioration.

Section 4

As the team closely monitors the patient's response to the interventions, a change in status becomes evident. The patient’s neurological condition continues to decline, with the Glasgow Coma Scale score dropping to 7, indicating a severe reduction in consciousness. The previously noted pupillary asymmetry has progressed, with the left pupil now fixed and dilated, raising the alarm for potential herniation. The respiratory pattern is becoming irregular, described as Cheyne-Stokes breathing, suggesting further compromise of the brainstem function. In response to these critical changes, the team immediately increases the hypertonic saline infusion rate and prepares to administer a high-dose barbiturate therapy in an attempt to reduce cerebral metabolic demand and ICP.

Simultaneously, the patient's cardiovascular status is deteriorating. Blood pressure has spiked to 190/105 mmHg, while bradycardia persists at 45 beats per minute, intensifying concerns about Cushing's reflex. Despite adjustments to the nicardipine infusion, the hypertension remains refractory. An urgent echocardiogram reveals a marked decrease in left ventricular ejection fraction, now at 35%, indicating stress-induced cardiomyopathy likely exacerbated by the neurogenic insult. The team initiates dobutamine to support cardiac output, carefully titrating to avoid further increases in blood pressure while balancing the need for adequate perfusion.

The evolving scenario presents a formidable challenge, demanding astute clinical judgment and rapid decision-making. The neurosurgical team is alerted for an emergent decompressive craniectomy, recognizing the increased risk of irreversible neurological damage if intracranial pressure is not swiftly controlled. Meanwhile, the patient's family is brought into the discussion, ensuring they understand the gravity of the situation and the potential outcomes. This juncture in the patient's care requires the team to remain vigilant, continuously reassessing and adjusting the treatment plan as they navigate this critical phase of the patient’s journey.

Section 5

As the team intensifies their efforts to stabilize the patient, new diagnostic results shed light on the underlying complexities. A repeat CT scan of the head confirms worsening cerebral edema with midline shift, supporting the suspicion of impending herniation. Laboratory tests reveal a significant electrolyte imbalance, including hyponatremia with a serum sodium level of 124 mEq/L, likely secondary to Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH) exacerbated by the neurological insult. The hypertonic saline infusion is adjusted accordingly to correct the sodium levels, mindful of the risks of central pontine myelinolysis if corrected too rapidly.

Simultaneously, arterial blood gas analysis indicates mixed metabolic and respiratory acidosis, with a pH of 7.28, pCO2 of 60 mmHg, and HCO3- of 18 mEq/L. The findings are suggestive of respiratory compromise due to impaired central regulation of breathing, compounded by metabolic derangements from systemic stress and hypoperfusion. The team evaluates the need for advanced airway management, considering intubation to provide controlled ventilation and optimize oxygenation. This decision is complicated by the need to minimize any additional increases in intracranial pressure during intubation.

The introduction of dobutamine has led to a modest improvement in cardiac output, though the blood pressure remains erratically elevated, complicating cerebral perfusion management. Lactate levels have risen to 4.5 mmol/L, indicating tissue hypoperfusion and anaerobic metabolism. The multidisciplinary team, in consultation with neurosurgery and critical care, deliberates on the timing and potential benefit of decompressive craniectomy, weighing the risks of the procedure against the possibility of further neurological decline. The patient's family is updated with these developments, emphasizing the critical nature of the situation and the potential for irreversible outcomes. Through thoughtful clinical reasoning and decisive actions, the team works to navigate the precarious balance between aggressive intervention and supportive care.
