Acute Mania and use of physical restraint - Nursing Case Study

Pathophysiology

• Primary mechanism: Acute mania is primarily driven by dysregulation of neurotransmitters, particularly an increase in dopamine and norepinephrine activity, leading to heightened mood, energy, and reduced need for sleep.

• Secondary mechanism: Dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis may exacerbate symptoms by increasing stress hormones, contributing to mood instability and impulsivity.

• Key complication: Due to impaired judgment and heightened energy, patients may exhibit behaviors that pose a risk to themselves or others, sometimes necessitating the use of physical restraints to ensure safety and stabilize acute symptoms.

Section 1

As the medical team continues to monitor the 32-year-old patient with acute mania, a notable change in his status presents new challenges. Despite initial interventions with increased dosages of Olanzapine to manage agitation, the patient's behavior becomes increasingly unpredictable. His blood pressure remains elevated at 165/105 mmHg, and his heart rate has risen to 118 bpm. Additionally, the patient exhibits signs of excessive sweating and tremors, suggesting possible lithium toxicity. Given his history of bipolar disorder and current lithium treatment, serum lithium levels are promptly ordered.

The laboratory results reveal a lithium level of 1.6 mEq/L, indicating mild toxicity, which could exacerbate his neurological symptoms and contribute to his current condition. Concurrently, his renal function tests show a slight elevation in serum creatinine, raising concerns about lithium clearance. These findings necessitate an immediate adjustment of his medication regimen and close monitoring of his kidney function. The team considers the potential need for temporary cessation of lithium therapy while implementing supportive care to address the acute symptoms.

Given the patient's heightened risk of self-harm and aggression, the decision is made to utilize physical restraints temporarily, while ensuring regular assessments for circulation and skin integrity. This approach is coupled with the initiation of a benzodiazepine to provide additional calming effects and mitigate the risk of further escalation. The healthcare team remains vigilant, balancing the need for safety with the potential risks associated with restraint use, and plans for a gradual re-evaluation of the patient's condition as his medication levels stabilize.

Section 2

As the medical team continues to closely monitor the patient, a new complication arises. Despite the administration of a benzodiazepine, the patient's agitation only partially subsides, and he begins to exhibit confusion and disorientation. This change prompts a thorough reassessment of his neurological status and a detailed evaluation of his current medication regimen. The patient's vital signs remain concerning, with a blood pressure of 168/108 mmHg and a heart rate of 122 bpm. Given these findings, the team is prompted to consider the cumulative effects of medication interactions and potential neurotoxicity.

Further diagnostic workup reveals a significant drop in serum sodium levels, with a value of 128 mEq/L, suggesting potential hyponatremia, possibly exacerbated by the concurrent use of lithium and other medications. This electrolyte imbalance could be contributing to his altered mental status and agitation. Alongside this, an ECG is conducted, showing a slight prolongation of the QT interval, raising concerns about the risks of cardiac arrhythmias given the patient's current electrolyte disturbances and medications.

In response to these findings, the healthcare team initiates a multifaceted intervention plan. They opt to gradually taper down the lithium dosage while introducing careful fluid and sodium management to address the hyponatremia. The decision is made to maintain the benzodiazepine for short-term sedation while closely monitoring the patient's cardiac status with continuous telemetry. The team collaborates to develop a comprehensive care plan that includes frequent reassessments of the patient's mental and physical status, ensuring that the interventions align with his evolving clinical picture. This approach highlights the importance of dynamic clinical reasoning and the need for ongoing adaptation as new challenges emerge in the management of acute mania with concurrent complications.

Section 3

As the healthcare team closely monitors the patient's response to the revised intervention plan, they observe both encouraging and concerning developments in his clinical status. Over the next 24 hours, the gradual tapering of lithium and careful correction of hyponatremia begin to show positive effects. The patient's serum sodium levels improve to 133 mEq/L, and his mental clarity shows signs of returning, with periods of lucidity becoming more frequent. However, despite these improvements, his agitation remains intermittently severe, necessitating continued use of the benzodiazepine for sedation.

During this period, the telemetry monitoring reveals occasional premature ventricular contractions (PVCs), which prompts the team to reassess the patient's cardiac status given the prolonged QT interval noted earlier. The patient's vital signs remain elevated, with a blood pressure of 160/100 mmHg and a heart rate fluctuating between 110 and 130 bpm. These findings suggest an ongoing sympathetic nervous system hyperactivity, likely exacerbated by the lingering effects of acute mania and the polypharmacy required for his management.

In light of these observations, the team convenes to refine the patient's care plan further. They consider the potential need for additional cardiac support and explore options such as beta-blockers to manage the elevated heart rate and blood pressure, while weighing the risks of further complicating the patient's current medication regimen. The situation underscores the necessity for nuanced clinical reasoning, as the team balances the risks of medication side effects with the pressing need to stabilize the patient's cardiac and neurological status. This ongoing complexity in the patient's care trajectory highlights the importance of interdisciplinary collaboration and vigilant monitoring to mitigate emerging complications.

Section 4

As the healthcare team continues to manage the patient's complex clinical picture, a new complication arises. During the afternoon shift, the patient exhibits increased respiratory effort, with a respiratory rate of 28 breaths per minute, and oxygen saturation dipping to 92% on room air. Auscultation reveals scattered crackles at the lung bases, suggesting possible pulmonary congestion. Concerned about potential fluid overload or cardiogenic causes, the team orders a chest X-ray and a set of arterial blood gases (ABGs). The chest X-ray indicates mild pulmonary edema, while the ABGs show a pH of 7.32, PaCO2 of 48 mmHg, PaO2 of 68 mmHg, and HCO3- of 24 mEq/L, indicating a mixed respiratory and metabolic acidosis.

These findings prompt the healthcare team to reassess the patient's fluid status and adjust the diuretic regimen. Given the patient's history of acute mania, lithium use, and current cardiac concerns, this development complicates the treatment landscape, requiring careful titration of medications to avoid destabilizing his mood or exacerbating electrolyte imbalances. The team decides to initiate low-dose furosemide to relieve the pulmonary congestion cautiously, while monitoring electrolyte levels closely to prevent further hyponatremia.

The emergence of pulmonary complications necessitates a reevaluation of the patient's current management strategy, particularly in relation to his cardiac function and fluid balance. The team contemplates the introduction of a beta-blocker to address the persistent tachycardia and hypertension, but this decision requires careful consideration of the potential impact on the patient's respiratory status and overall stability. This scenario underscores the critical role of ongoing assessment, interdisciplinary collaboration, and dynamic adjustment of the treatment plan to navigate the evolving challenges in the patient's care.

Section 5

As the team monitors the patient's response to the low-dose furosemide, they observe a gradual improvement in respiratory status. Within a few hours, the patient's respiratory rate decreases to 24 breaths per minute, and oxygen saturation improves to 95% on room air. However, as the evening progresses, the patient begins to exhibit signs of increased agitation and confusion, raising concerns about the impact of fluid and electrolyte shifts on his mental status. A repeat set of electrolytes reveals a sodium level of 130 mEq/L, indicating mild hyponatremia, likely exacerbated by the diuretic therapy.

Despite the improved pulmonary status, the patient's cardiovascular assessment reveals persistent tachycardia, with a heart rate consistently in the range of 110-115 beats per minute. Blood pressure remains elevated at 150/92 mmHg. The healthcare team is faced with the complex task of balancing the need to manage the patient's cardiovascular symptoms without precipitating further mental health instability. After a thorough review of the patient's medication regimen and potential interactions, the decision is made to cautiously introduce a low-dose beta-blocker, with plans for close monitoring of both cardiac and mental health parameters.

This clinical decision necessitates an interdisciplinary approach, involving collaboration with psychiatry to ensure that the beta-blocker does not exacerbate manic symptoms. The team also emphasizes regular reassessment of the patient's fluid status, mental state, and vital signs. These steps are crucial as they continue to navigate the delicate balance between managing acute physiological complications and maintaining psychiatric stability. The team's ability to adapt the treatment plan in response to evolving clinical findings highlights the importance of comprehensive, dynamic care in complex cases like this one.
