venous thromboembolism - Nursing Case Study

Pathophysiology

• Primary mechanism: Venous stasis occurs when blood flow through the veins slows or pools, often due to immobility or prolonged bed rest, increasing the risk of clot formation.

• Secondary mechanism: Endothelial injury, caused by factors like surgery or trauma, disrupts the normal anticoagulant properties of the vessel wall, promoting platelet aggregation and fibrin formation.

• Key complication: Pulmonary embolism can arise when a clot dislodges and travels to the lungs, causing potentially life-threatening respiratory and circulatory issues.

• Vital signs: Blood pressure 140/90 mmHg, heart rate 110 bpm, respiratory rate 24 breaths per minute, temperature 98.9°F, oxygen saturation 92% on room air

Section 1

As the clinical team begins the initial assessment of the patient, they note the significant swelling and erythema in the left leg, consistent with her previous history of deep vein thrombosis. The patient expresses increased discomfort upon palpation of the calf area, and the leg feels warm to touch. Given the patient's history of venous thromboembolism and current symptoms, the clinical team suspects a recurrence of deep vein thrombosis with a possible pulmonary embolism.

Laboratory tests are promptly ordered, including a D-dimer test, which returns significantly elevated, suggesting the presence of an abnormal blood clot. A Doppler ultrasound of the left leg confirms the presence of a thrombus in the deep venous system. Additionally, a CT pulmonary angiogram is conducted due to her symptoms of shortness of breath and chest discomfort, revealing a small, yet significant, embolus in the right pulmonary artery. The patient's oxygen saturation remains at 92% despite being on room air, and she exhibits mild tachypnea and tachycardia.

In response to these findings, the medical team initiates an adjustment of her anticoagulation therapy. Warfarin is temporarily held, and the patient is started on a therapeutic dose of low molecular weight heparin to provide rapid anticoagulation. The team discusses the importance of closely monitoring her INR levels to ensure therapeutic anticoagulation while mitigating the risk of further embolic events. The patient is also educated on lifestyle modifications to reduce her risk factors, such as increasing mobility and managing her diabetes and hypertension more effectively. As the team awaits further lab results and monitors her response to treatment, the focus shifts to preventing further complications and ensuring stabilization.

Section 2

As the medical team continues to monitor the patient, they observe a change in her respiratory status. The patient's oxygen saturation, which was previously at 92% on room air, begins to drop to 88%, prompting the initiation of supplemental oxygen therapy at 2 liters via nasal cannula. Despite this intervention, her oxygen saturation struggles to rise above 90%, and her respiratory rate increases to 24 breaths per minute, indicating worsening respiratory compromise. Additionally, the patient's heart rate remains elevated at 110 beats per minute, suggesting persistent tachycardia. The clinical team is concerned about the potential for further pulmonary complications and decides to reassess the patient's condition with a repeat CT pulmonary angiogram to evaluate for any progression of the embolic event.

The repeat CT pulmonary angiogram reveals an additional small embolus in the left pulmonary artery, suggesting further propagation of thrombotic activity despite anticoagulation therapy. In light of these findings, the medical team is faced with the clinical decision of whether to intensify anticoagulation therapy or consider advanced interventions such as thrombolysis. Given the patient's hemodynamic stability, with a blood pressure reading of 124/78 mmHg and no signs of cardiovascular collapse, the team opts to increase the dosage of low molecular weight heparin while maintaining vigilant monitoring for any signs of bleeding or hemodynamic instability.

Concurrently, the nursing staff implements non-pharmacological interventions to support the patient's respiratory function, including positioning her in a semi-Fowler's position to optimize lung expansion and encouraging deep breathing exercises. The team also reinforces the importance of early mobilization and leg exercises to prevent further venous stasis. As the clinical team integrates these findings and interventions, they remain alert for any new complications, understanding that timely response and adaptation to the evolving clinical picture are crucial in managing this complex case of venous thromboembolism.

Section 3

As the medical team continues to manage the patient's condition, they observe a slight improvement in her respiratory status following the increased dosage of low molecular weight heparin and non-pharmacological interventions. Her oxygen saturation rises slightly to 91% on 2 liters of supplemental oxygen, and her respiratory rate decreases to 22 breaths per minute. However, the patient begins to report new onset of mild chest discomfort and increased anxiety, prompting further assessment by the clinical team.

The nursing staff conducts a thorough cardiovascular and respiratory assessment. Upon auscultation, there is no change in the lung sounds, but an S3 heart sound is noted, raising concerns about potential right heart strain. An EKG is performed, revealing sinus tachycardia with no acute ischemic changes. To further investigate the underlying cause of her chest discomfort, a set of cardiac biomarkers is ordered, revealing mildly elevated troponin levels. This finding suggests possible right ventricular strain secondary to the increased pulmonary pressures from the embolic burden.

The clinical team discusses these findings and recognizes the potential risk of right heart failure if the pulmonary pressures are not controlled. While the patient remains hemodynamically stable, these developments necessitate close monitoring and prompt adaptation of the treatment plan. The team decides to maintain the current anticoagulation regimen while considering the need for a cardiology consult to evaluate the potential benefits of adjunctive treatments such as pulmonary vasodilators or advanced imaging to assess right ventricular function. The plan is to continue supportive care measures and reinforce patient education on symptom monitoring, ensuring the team is prepared to act swiftly should the patient's condition deteriorate further.

Section 4

A few hours after the initial assessment and intervention adjustments, the patient begins to show signs of further clinical deterioration. Her oxygen saturation, which had previously improved, drops to 88% despite being on 2 liters of supplemental oxygen. The patient's respiratory rate increases again to 28 breaths per minute, and she becomes visibly anxious and diaphoretic. In response to these changes, the nursing team performs another comprehensive assessment. Upon auscultation of the lungs, there is now a notable decrease in breath sounds at the right lung base, suggesting possible atelectasis or pleural effusion. Additionally, the patient reports worsening chest discomfort and a new sensation of palpitations.

The clinical team acts swiftly, ordering a chest X-ray to identify any structural changes in the lungs and a CT pulmonary angiogram to assess the current state of the pulmonary emboli. The chest X-ray reveals a small right pleural effusion, consistent with the recent reduction in breath sounds. The CT pulmonary angiogram shows persistent emboli with evidence of slightly increased right ventricular dilation compared to previous imaging, indicating progression of right ventricular strain. These findings confirm the team’s concern regarding the patient's evolving right heart strain and potential heart failure.

Recognizing the urgency of the situation, the medical team consults with cardiology to explore possible interventions to alleviate right ventricular pressure. Discussions focus on the potential use of pulmonary vasodilators like sildenafil or the consideration of catheter-directed thrombolysis, given the worsening hemodynamic compromise. The patient is informed about the new findings and potential treatment options, ensuring she understands the seriousness of her condition while continuing supportive measures, including monitoring vital signs closely and adjusting oxygen therapy as needed. The team remains vigilant, prepared to escalate care as necessary while striving to stabilize her condition and prevent further complications.

Section 5

After consulting with cardiology, the team decides to initiate treatment with sildenafil to help reduce the pressure on the right side of the heart by promoting pulmonary vasodilation. The patient is carefully monitored for any adverse reactions to this medication. Within an hour of the initial dose, there is a slight improvement in her oxygen saturation, which increases to 91%. However, her heart rate remains elevated at 110 beats per minute, and her blood pressure is slightly reduced at 98/58 mmHg, indicating a cautious balance between the benefits and potential side effects of the vasodilator.

Despite these changes, the patient continues to experience significant chest discomfort and anxiety, prompting the team to start a low-dose intravenous morphine infusion to alleviate pain and anxiety, which also serves to decrease cardiac workload. Lab results show an increase in cardiac biomarkers, with troponin levels rising to 0.8 ng/mL, suggesting myocardial strain likely related to the right ventricular overload. The team discusses these findings with the patient, explaining that while there are signs of stress on the heart, they are cautiously optimistic that the current interventions will stabilize her condition.

As the night progresses, the nursing team remains vigilant, reassessing her respiratory status frequently. They note that her respiratory rate has decreased slightly to 24 breaths per minute, and her anxiety appears somewhat reduced with pain management. However, they remain alert for any signs of further decompensation, such as worsening hypoxemia or increased heart rate, which would necessitate urgent escalation of care. The plan includes repeat imaging and cardiac evaluations in the morning to assess the effectiveness of current treatments and to guide further interventions. The focus remains on preventing progression to severe right heart failure while supporting the patient's respiratory and hemodynamic status.
