hydrocephalus - Nursing Case Study

Pathophysiology

• Primary mechanism: Hydrocephalus is primarily caused by an imbalance between the production and absorption of cerebrospinal fluid (CSF), leading to its accumulation. This can result from obstruction within the ventricular system, such as at the aqueduct of Sylvius, blocking CSF flow and increasing intracranial pressure.

• Secondary mechanism: Impaired CSF absorption can occur due to dysfunction of the arachnoid villi, often due to inflammation or hemorrhage. This impedes CSF reabsorption into the venous system, further exacerbating fluid accumulation.

• Key complication: The increased intracranial pressure can lead to compression of brain tissues, resulting in symptoms like headaches, nausea, and potentially severe neurological deficits if not managed promptly.

Section 1

The patient was admitted to the hospital for further evaluation due to her worsening symptoms of hydrocephalus. During the initial assessment, the neurological examination revealed further concerning findings: the patient demonstrated increased difficulty with coordination and balance, evidenced by a positive Romberg test and gait ataxia. She also exhibited mild disorientation to time and place, suggesting the potential onset of cognitive impairment. Her visual acuity test showed bilateral papilledema, indicative of increased intracranial pressure. These findings necessitated urgent neuroimaging to assess the extent of ventricular enlargement and potential obstructive causes.

Subsequent MRI results revealed significant dilation of the lateral and third ventricles, with a notable narrowing of the cerebral aqueduct, consistent with aqueductal stenosis. This finding supported the primary mechanism of her hydrocephalus and explained the progressive nature of her symptoms. Laboratory tests showed mild hyponatremia, possibly secondary to the effects of acetazolamide, which the patient had been taking to manage her condition. Her blood pressure remained elevated at 155/98 mmHg, requiring adjustment of her antihypertensive regimen to minimize further complications.

The clinical team decided to prioritize surgical intervention, considering the patient's deteriorating neurological status. A ventriculoperitoneal (VP) shunt was recommended to alleviate the elevated intracranial pressure by diverting excess CSF. The patient and her family were counseled about the risks and benefits of the procedure, as well as the potential for shunt-related complications, such as infection or malfunction. As the patient prepared for surgery, her care team continued to monitor her vital signs and neurological status closely, aiming to stabilize her condition and prevent any further decline.

Section 2

As the surgical team proceeded with the placement of the ventriculoperitoneal (VP) shunt, the patient was closely monitored in the neurosurgical intensive care unit. Initially, the surgery appeared successful, with immediate postoperative assessments indicating a reduction in intracranial pressure, as evidenced by the gradual resolution of papilledema during a follow-up fundoscopic examination. The patient demonstrated modest improvement in orientation and a slight reduction in gait ataxia, suggesting some relief from the effects of hydrocephalus. Her blood pressure was managed effectively with the adjusted antihypertensive regimen, stabilizing around 130/85 mmHg.

However, within 48 hours, the patient began to exhibit new concerns. She developed a persistent low-grade fever of 100.4°F (38°C) and reported increased abdominal tenderness. Her white blood cell count increased to 14,500/mm³, raising suspicion for a potential shunt-related infection. The clinical team initiated broad-spectrum antibiotics while awaiting further diagnostic testing, including a shunt tap and cultures, to determine the causative organism. The patient's neurological status fluctuated, with episodes of confusion and mild headache returning, which raised concerns about shunt malfunction or infection and necessitated urgent evaluation.

These developments required the clinical team to reassess the patient’s condition comprehensively. A repeat MRI was ordered to evaluate the shunt’s function and rule out any obstruction or improper placement. The team also planned for serial lumbar punctures to monitor CSF pressure and composition. The patient's care plan was adjusted to include additional supportive measures, such as maintaining a strict sterile environment to prevent further infections and close monitoring of her cognitive status. These steps were critical in guiding the team to refine their interventions and stabilize the patient, aiming to avert further complications and optimize her recovery trajectory. This ongoing assessment would determine the next steps in her treatment, ensuring a comprehensive approach to her complex clinical needs.

Section 3

The clinical team proceeded with the next phase of the patient's evaluation, focusing on the new diagnostic results. The results from the shunt tap revealed cloudy cerebrospinal fluid with an elevated white blood cell count, predominantly neutrophils, and decreased glucose levels, consistent with an infection. Cultures from the CSF grew Staphylococcus epidermidis, a common organism associated with shunt infections. Meanwhile, the MRI indicated adequate placement of the VP shunt with no apparent obstruction, though there was mild ventriculomegaly likely due to partial shunt malfunction related to infection.

In light of these findings, the team intensified their antibiotic regimen, switching to a targeted therapy with vancomycin based on the susceptibility profile of the isolated organism. The patient's low-grade fever persisted, accompanied by a slight increase in heart rate to 110 beats per minute and a blood pressure of 145/90 mmHg, suggesting ongoing infection and inflammatory response. Regular neurological checks indicated fluctuating levels of consciousness, with periods of lethargy interspersed with confusion, reinforcing the need for vigilant monitoring to detect any signs of worsening hydrocephalus or increased intracranial pressure.

The situation prompted discussions about the possibility of shunt revision or external drainage to manage the infection more effectively. The team decided to continue close observation and reassess the patient's response to the adjusted treatment, recognizing the need to balance infection control with maintaining optimal shunt function. By keeping a close watch on her neurological status and adjusting the care plan accordingly, the team aimed to stabilize her condition and prevent further complications, steering her path towards recovery while preparing for any necessary surgical interventions.

Section 4

A few days into the intensified antibiotic regimen, the patient exhibited a notable change in status, prompting a re-evaluation of her condition. The patient developed a new onset of severe headache and an increased frequency of vomiting, raising concerns about the effectiveness of the current treatment plan. Neurological assessments revealed a further decline in her level of consciousness, with increased periods of confusion and disorientation, suggestive of worsening intracranial pressure despite the ongoing antibiotic therapy. The vital signs showed a persistent low-grade fever of 38.3°C (100.9°F), heart rate now elevated to 120 beats per minute, and blood pressure stable at 140/88 mmHg, indicating a sustained systemic inflammatory response.

In response to these developments, the clinical team ordered a repeat MRI and a full laboratory workup, including complete blood count and inflammatory markers. The MRI revealed increased ventriculomegaly, suggesting further compromise in the shunt system, likely secondary to the unresolved infection. The laboratory results showed a white blood cell count of 15,000/µL with 85% neutrophils, and elevated C-reactive protein at 120 mg/L, confirming persistent inflammation and possible treatment resistance.

The patient's deteriorating status dictated a more aggressive intervention strategy. After multidisciplinary team discussions, the decision was made to proceed with external ventricular drainage (EVD) to relieve intracranial pressure and provide direct management of the infected CSF. This would allow for better control of the infection while planning for a potential shunt revision. The patient's care plan was adjusted to include daily monitoring of CSF output and composition, alongside continued vancomycin therapy, with a view to optimizing her neurological function and preparing for further surgical intervention if necessary. As these steps were implemented, the team remained vigilant, ready to adapt the treatment plan based on the patient's evolving clinical picture.

Section 5

Following the implementation of external ventricular drainage (EVD), the patient's initial response was cautiously optimistic. Over the first 24 hours, the CSF output gradually increased, indicating successful decompression of the ventricles. Neurologically, there was a slight improvement in her level of consciousness; she became more responsive to verbal stimuli and exhibited reduced periods of confusion. However, her severe headache persisted, albeit with a slight decrease in intensity. Her vital signs showed marginal improvement, with a heart rate reduced to 110 beats per minute and a slight decline in temperature to 37.9°C (100.2°F), hinting at a possible early response to the interventions.

Despite these promising signs, new complications emerged as the CSF analysis provided critical insights. The laboratory results indicated a high protein content and decreased glucose levels in the CSF, suggestive of ongoing bacterial meningitis. Cultures confirmed the presence of a resistant strain of Staphylococcus epidermidis, necessitating a modification in the antibiotic regimen. The infectious disease team recommended the addition of rifampin to the existing vancomycin therapy to tackle the resistant organism more effectively.

As the team adjusted the treatment strategy, they remained acutely aware of the potential for additional complications, such as CSF leaks or secondary infections. The plan was to maintain rigorous monitoring and frequent re-evaluations to adapt the management plan swiftly should the patient's condition change. The next critical step was determining the timing and feasibility of a shunt revision, contingent upon the resolution of the infection and stabilization of her clinical status. The team's proactive approach and coordinated care were essential in navigating the complexities of her condition, aiming to restore her neurological function and prevent further deterioration.
