Dokter mendiagnosis pasien dengan stroke iskemik akut - Nursing Case Study

Pathophysiology

• Primary mechanism: Cerebral ischemia

Atrial fibrillation leads to the formation of emboli in the heart, which can travel to the cerebral circulation and occlude an artery supplying the brain, resulting in an ischemic stroke. This is evident in the acute infarction seen in the left frontal-parietal region and internal capsule, causing right-sided weakness and facial asymmetry.

• Secondary mechanism: Hypertension and atherosclerosis

Chronic hypertension and elevated cholesterol levels contribute to the development of atherosclerosis, which narrows and stiffens blood vessels, increasing the risk of thromboembolic events and further exacerbating cerebral ischemia.

• Key complication: Neurological deficits

The region affected by the infarct correlates with the patient's symptoms, such as right-sided hemiparesis, dysarthria, and facial droop, significantly impacting mobility and communication abilities.

Section 1

As the patient's condition is monitored in the emergency department, the medical team observes a significant change in his status. Approximately six hours after admission, the patient begins to exhibit new neurological symptoms: his level of consciousness decreases, noted by a drop in his Glasgow Coma Scale (GCS) score to 12 (E3, V3, M6). Additionally, there is worsening of his speech, now almost unintelligible, and increased weakness in his right extremities, with the strength in his right arm reducing to 1/5 and his right leg to 2/5. The patient also exhibits a new onset of right-sided homonymous hemianopia, indicating a possible extension of the cerebral infarction.

Given these developments, the healthcare team orders a repeat CT scan of the head. The new imaging reveals increased cerebral edema surrounding the infarcted area in the left frontal-parietal region, with a slight midline shift, suggesting a risk of herniation. The presence of cerebral edema and the midline shift are concerning findings that could explain the patient's declining neurological status. In response to these findings, the team initiates measures to reduce intracranial pressure, including elevating the head of the bed, administering hypertonic saline, and considering consultation with a neurosurgeon for further management.

These changes necessitate a re-evaluation of the patient's treatment plan. The immediate focus shifts to stabilizing the patient's neurological status and preventing further complications. The development of cerebral edema complicates the clinical picture, emphasizing the importance of closely monitoring the patient's vital signs, neurological status, and response to interventions. The medical team must balance aggressive management of intracranial pressure with the patient's cardiovascular status, given his history of hypertension and atrial fibrillation.

Section 2

As the medical team implements measures to manage the patient's intracranial pressure, they need to closely monitor his response to these interventions. After administering hypertonic saline and elevating the head of the bed, the patient's vital signs are reassessed. His blood pressure has decreased slightly to 180/105 mmHg, while his heart rate remains irregular at 100 beats per minute. His oxygen saturation is stable at 95% on 2 liters of nasal cannula oxygen. Neurologically, the patient's Glasgow Coma Scale score remains at 12, indicating no immediate improvement in his level of consciousness. However, there is a slight improvement in his speech, which is now marginally more coherent, suggesting a possible positive response to the reduction in intracranial pressure.

Despite these interventions, the patient continues to exhibit significant weakness in his right extremities, with muscle strength unchanged at 1/5 in the right arm and 2/5 in the right leg. The new onset of right-sided homonymous hemianopia persists, and the medical team remains vigilant for any signs of further deterioration. Repeat blood tests show a blood glucose level that has decreased to 220 mg/dL, reflecting a partial response to the initial management of his hyperglycemia. Serum electrolytes remain within normal limits, ensuring that the interventions to manage cerebral edema have not adversely affected his electrolyte balance.

Given the complexity of the patient's condition, the healthcare team must continue to balance the management of intracranial pressure with the patient's cardiovascular needs. A neurosurgical consultation is considered to evaluate the necessity of further interventions, such as surgical decompression if the cerebral edema does not respond adequately to medical management. The team's ongoing assessment and timely interventions are crucial in preventing further complications and stabilizing the patient's neurological status as they work to optimize his treatment plan and prepare for potential transfer to a higher level of care if required.

Section 3

As the medical team continues to monitor the patient's response to the interventions, they observe a change in his neurological status. Approximately six hours after the initial treatment, the patient begins to display increased lethargy, and his Glasgow Coma Scale score drops to 10, with scores of 3 for eye opening, 3 for verbal response, and 4 for motor response. This change prompts further evaluation of his neurological condition. The patient's speech has become less coherent again, and he struggles to follow simple commands. His muscle strength remains diminished, with no improvement in the right arm and leg, maintaining at 1/5 and 2/5 respectively.

In light of the patient's deteriorating neurological status, an urgent repeat CT scan of the head is conducted. The imaging reveals a slight increase in cerebral edema, with midline shift indicating worsening of the intracranial pressure. The medical team is concerned about the risk of brain herniation and promptly discusses the findings with the neurosurgical team. They consider the possibility of surgical intervention, such as hemicraniectomy, to relieve pressure and prevent further neurological decline.

The patient's blood pressure continues to be challenging to manage, now reading at 185/110 mmHg despite ongoing antihypertensive therapy. His heart rate remains irregular, consistent with atrial fibrillation, and his oxygen saturation is stable at 94% on 3 liters of nasal cannula oxygen. The interdisciplinary team, including critical care specialists, collaborates to refine the treatment plan, focusing on aggressive medical management of intracranial pressure while preparing for potential surgical intervention. This comprehensive approach aims to stabilize the patient's condition and mitigate the risk of further complications as they navigate this critical phase of his care.

Section 4

As the medical team continues to monitor the patient, they observe a new complication emerging. Approximately 12 hours after the initial presentation, the patient's condition further deteriorates. His Glasgow Coma Scale score drops to 8, with scores of 2 for eye opening, 2 for verbal response, and 4 for motor response, indicative of a worsening level of consciousness. The team notes that the patient is now exhibiting Cheyne-Stokes respiration, a pattern of irregular breathing that suggests increased intracranial pressure. Additionally, the patient’s pupils are noted to be unequal, with the left pupil measuring 5 mm and sluggishly reactive to light while the right pupil remains at 3 mm and reactive, raising concerns about potential transtentorial herniation.

In response to these alarming signs, the medical team intensifies their efforts to manage the patient’s intracranial pressure. Mannitol is administered intravenously to promote osmotic diuresis, and hypertonic saline is considered to further reduce cerebral edema. Despite these measures, the patient's blood pressure remains elevated at 190/115 mmHg, and his heart rate fluctuates between 100 and 120 beats per minute, with persistent irregularity due to atrial fibrillation. The neurosurgical team is on standby as the critical care specialists continue to optimize medical management, knowing that surgical intervention may become unavoidable if the patient’s neurological status does not stabilize.

The interdisciplinary team also reassesses the patient's arterial blood gas results, which reveal a pH of 7.35, PaCO2 of 48 mmHg, and PaO2 of 75 mmHg on 4 liters of nasal cannula oxygen, indicating respiratory acidosis with mild hypoxemia. This prompts a reevaluation of his respiratory support, and the decision is made to escalate to high-flow oxygen therapy to improve gas exchange. The team remains vigilant, aware that the next few hours are crucial in determining the patient's trajectory and the need for potential surgical intervention.

Section 5

As the medical team continues to manage the patient's condition, they notice a concerning change in his status. Despite the administration of mannitol and the consideration of hypertonic saline, the patient’s neurological signs suggest further deterioration. Approximately 24 hours after the initial presentation, the patient's Glasgow Coma Scale score remains low at 7, with scores of 2 for eye-opening, 2 for verbal response, and 3 for motor response, indicating a worsening level of consciousness. The unequal pupil size persists, with the left pupil now measuring 6 mm and showing minimal reactivity, while the right pupil remains at 3 mm and reactive. This raises an increased suspicion of progressive transtentorial herniation, necessitating immediate reassessment by the neurosurgical team.

A repeat CT scan of the brain is ordered to assess any changes in the intracranial environment. The imaging reveals a significant midline shift of 5 mm to the right, suggesting increased mass effect from the infarcted area and surrounding edema. The CT scan also highlights signs of impending herniation, which explains the patient's neurological decline. Concurrently, the patient's blood pressure has increased further to 200/120 mmHg, despite aggressive medical management, and his heart rate is now consistently at 120 beats per minute with continued irregularity due to atrial fibrillation.

These findings prompt an urgent discussion among the interdisciplinary team regarding the need for surgical intervention. The neurosurgical team evaluates the potential for decompressive craniectomy to relieve intracranial pressure and prevent further neurological damage. The critical care team continues to support the patient with high-flow oxygen therapy, monitoring arterial blood gases closely. The patient's respiratory status shows slight improvement, with a pH of 7.38, PaCO2 of 45 mmHg, and PaO2 of 80 mmHg, though they remain cautious of any further complications that may arise. The decision for surgery is weighed against the risks and the potential for improved neurological outcomes, marking a pivotal point in the patient's care trajectory.
