Stroke - hemorrhagic with nsertion of EVD and measurement of ICP - Nursing Case Study

Pathophysiology

• Primary mechanism: Hemorrhagic stroke occurs when a cerebral blood vessel ruptures, leading to intracerebral bleeding. This increases intracranial pressure (ICP) as blood accumulates, compressing brain tissue and disrupting blood flow.

• Secondary mechanism: The expanding hematoma exacerbates cerebral edema, further elevating ICP. This results in a vicious cycle of decreased cerebral perfusion and neuronal injury, potentially causing herniation if not managed promptly.

• Key complication: Insertion of an external ventricular drain (EVD) facilitates ICP monitoring and cerebrospinal fluid drainage, crucial in preventing herniation and reducing secondary brain injury by alleviating pressure.

Section 1

As the patient is transferred to the intensive care unit following the insertion of the external ventricular drain (EVD), the initial assessment reveals critical findings. The patient's Glasgow Coma Scale score has deteriorated to 8, indicating a significant decrease in consciousness. Neurological examination shows pronounced right-sided hemiparesis, suggesting increased pressure on the left cerebral hemisphere. The EVD is actively draining cerebrospinal fluid, with an initial intracranial pressure (ICP) reading of 32 mmHg, well above the normal range. This elevated ICP confirms the severity of cerebral edema and ongoing risk of cerebral herniation.

Laboratory results reveal a concerning coagulopathy, with an international normalized ratio (INR) of 3.5, a consequence of warfarin therapy. Given the patient's critical state and risk of further bleeding, reversal of anticoagulation becomes a priority. The clinical team initiates treatment with vitamin K and fresh frozen plasma to rapidly correct the INR. Follow-up imaging, including a CT scan, shows an expanding hematoma with midline shift, reinforcing the need for vigilant monitoring and potential surgical intervention.

Despite initial interventions, the patient's oxygen saturation remains low at 85% despite supplemental oxygen, necessitating intubation to secure the airway and ensure adequate ventilation. This change in respiratory status highlights the intricate balance required in managing multiple systemic complications. The healthcare team must now prioritize stabilizing the patient's hemodynamics, optimizing cerebral perfusion, and preparing for possible neurosurgical evaluation, while continuously reassessing the effectiveness of the current treatment strategy in the face of evolving challenges.

Section 2

As the intensive care unit team continues their vigilant monitoring, a new set of diagnostic results reveals further complications that demand immediate attention. The most recent arterial blood gas analysis indicates a worsening metabolic acidosis, with a pH of 7.25, a bicarbonate level of 18 mEq/L, and an elevated lactate level of 4.5 mmol/L. These findings suggest inadequate tissue perfusion and possible systemic shock, likely exacerbated by the ongoing intracranial hypertension and impaired cerebral perfusion. Concurrently, the patient's blood pressure has become increasingly labile, with episodes of hypotension alternating with spikes in systolic pressure exceeding 180 mmHg, indicative of autonomic dysregulation and an increased risk for further hemorrhagic events.

In parallel, the latest CT angiography reveals vasospasm in the cerebral arteries, a common complication following subarachnoid hemorrhage and a contributing factor to the patient's deteriorating neurological status. This vasospasm is likely causing additional ischemic insult to already compromised brain tissue, necessitating aggressive management. The clinical team decides to implement a triple-H therapy regimen (hypertension, hypervolemia, and hemodilution) to counteract the vasospasm and to enhance cerebral blood flow. This decision requires careful titration of intravenous fluids and vasopressors, demanding precise adjustments to maintain the delicate balance between optimizing cerebral perfusion and avoiding exacerbation of the existing hematoma.

The evolving complexity of the patient's condition highlights the need for continuous multidisciplinary collaboration and reassessment of therapeutic priorities. The team must now prepare for the possibility of emergent surgical intervention, while simultaneously addressing the metabolic derangements and hemodynamic instability. This intricate scenario challenges the healthcare providers to apply advanced critical thinking and clinical judgment to navigate the multifaceted care needs, ensuring that each intervention is precisely tailored to mitigate risks and optimize patient outcomes in this critical phase.

Section 3

As the ICU team intensifies their monitoring of the patient, they note a new complication: the emergence of acute kidney injury (AKI), likely secondary to the ongoing metabolic acidosis and hemodynamic instability. Laboratory tests reveal a marked increase in serum creatinine to 2.8 mg/dL from a baseline of 1.0 mg/dL, alongside a significant decrease in urine output to less than 20 mL/hour, indicative of oliguria. This renal impairment exacerbates the metabolic acidosis, contributing further to the patient's systemic instability. The nephrology team is consulted promptly to assess the need for renal replacement therapy, while the ICU team meticulously adjusts fluid management to balance between correcting the acidosis and preventing fluid overload, which could worsen intracranial pressure.

Concurrently, the patient's neurological status displays alarming changes. Despite the ongoing triple-H therapy, the patient's Glasgow Coma Scale (GCS) score drops from 9 to 7, suggesting a decline in neurological function. The external ventricular drain (EVD) indicates a sustained increase in intracranial pressure (ICP) to 28 mmHg, underscoring the urgency of the situation. The team considers escalating therapeutic interventions, including the administration of hypertonic saline or mannitol to reduce ICP, while simultaneously preparing for the potential need for decompressive craniectomy should the patient fail to respond to medical management.

In light of these developments, the multidisciplinary team convenes to reassess the patient's care plan. They must prioritize interventions that address the critical balance between maintaining cerebral perfusion and managing systemic complications. The integration of nephrology, neurosurgery, and critical care expertise is pivotal in crafting a cohesive approach to navigate this complex clinical scenario. As the team deliberates, they remain acutely aware that every decision must be executed with precision, given the narrow therapeutic margins and the profound implications for the patient's prognosis.

Section 4

As the multidisciplinary team delves deeper into the patient's condition, new diagnostic results shed light on the evolving challenges. A repeat CT scan of the brain reveals worsening cerebral edema, with a midline shift of 5 mm, suggesting increased mass effect and a heightened risk for herniation. This finding correlates with the neurological decline noted earlier and compels the team to expedite their decision-making regarding more aggressive interventions. Concurrently, an arterial blood gas analysis indicates a persistent metabolic acidosis with a pH of 7.25, bicarbonate level of 14 mEq/L, and a base excess of -10 mEq/L, despite ongoing fluid resuscitation efforts and adjustments in ventilation parameters.

The nephrology team, after a thorough evaluation, concludes that renal replacement therapy is necessary to manage the acute kidney injury and to aid in correcting the severe acidosis. They recommend initiating continuous renal replacement therapy (CRRT) given the patient's hemodynamic instability, which requires meticulous attention to fluid balance and electrolyte management. Meanwhile, the critical care team prepares to administer hypertonic saline to counteract the intracranial hypertension, carefully calibrating the timing and dosing to avoid exacerbating the fluid overload risk.

These diagnostic revelations and the subsequent therapeutic strategies underscore the complexity of the patient's case, demanding an integrated and dynamic approach from the entire care team. The situation remains volatile, with the need for constant reassessment and adaptation of the treatment plan. As the patient's journey unfolds, every intervention is a critical juncture that could determine the trajectory of recovery or deterioration, emphasizing the importance of clinical acumen and interdisciplinary collaboration in navigating this intricate clinical landscape.

Section 5

As the multidisciplinary team reconvenes to assess the impact of their interventions, the patient's condition presents new challenges. Despite the administration of hypertonic saline to address intracranial hypertension, the patient's intracranial pressure (ICP) remains elevated, with readings consistently above 25 mmHg. The neurosurgery team expresses concern about the potential for further neurological deterioration and the risk of herniation given the ongoing midline shift observed on imaging. The patient exhibits signs of worsening neurological status, including sluggish pupillary response and a decrease in Glasgow Coma Scale (GCS) score to 6, necessitating urgent consideration of additional surgical options or more aggressive medical therapy.

Simultaneously, the initiation of continuous renal replacement therapy (CRRT) has begun to show signs of stabilizing the patient's metabolic acidosis, albeit slowly. Arterial blood gas analysis reveals a slight improvement, with a pH of 7.30, bicarbonate level of 16 mEq/L, and base excess of -8 mEq/L. However, the critical care team remains vigilant in monitoring for potential complications such as electrolyte imbalances and hemodynamic instability, both of which could exacerbate the patient's precarious condition. The patient's blood pressure has been labile, with episodes of hypotension requiring adjustments in vasopressor support, highlighting the delicate balance required in managing fluid status while ensuring adequate cerebral perfusion.

Amid these developments, a new complication emerges: the patient develops signs of acute respiratory distress, characterized by increased work of breathing and decreasing oxygen saturation levels, dropping to 85% despite supplemental oxygen. A chest X-ray reveals pulmonary edema, likely secondary to fluid shifts and aggressive fluid management strategies. This respiratory compromise necessitates immediate intubation and mechanical ventilation, with adjustments to ventilator settings to optimize oxygenation while minimizing further cerebral compromise. This new development adds another layer of complexity, requiring the team to recalibrate their approach and prioritize interventions to stabilize the patient's respiratory status while continuing to address the ongoing intracranial and metabolic challenges.
