If the patient has pericardial effusion and there is no apparent leakage from the drainage tube, and no fluid drainage, it is possible to consider removing the tube after two days.

In cases like this, active drainage is sometimes still necessary because pericardial effusion is a type of exudate, which can be inflammatory. Draining can help relieve the cardiac workload. If the drainage tube is clear and there is no fluid leakage, removing the tube after about two days can be considered.

However, there is a situation where the tube must not be removed. If there is fluid leaking from the pericardial effusion, or if the symptoms of pericardial effusion are still severe, and there is some fluid remaining in the pericardial cavity, the tube should not be removed.

What should I do if pericardial effusion prevents me from lying down?

If pericardial effusion occurs and the patient cannot lie flat, it indicates that this heart failure has not been timely corrected. The patient should immediately go to the hospital to use medications, especially cardiovascular and diuretic drugs, to improve cardiac function and alleviate the current condition of the patient. Generally, it is still recommended that patients primarily adopt a semi-recumbent position to reduce the load on the heart muscle, thereby improving symptoms. If the patient cannot lie flat, do not force it; a semi-recumbent position will suffice as it makes no significant difference. With aggressive internal medicine treatment, pericardial effusion can be alleviated, and the patient's symptoms will improve. However, during this period, it is still necessary to monitor changes in the patient's heart rate, blood pressure, and pulse, and to address any issues promptly.

Does pericardial effusion increase or decrease pulse pressure?

In general, if a patient develops pericardial effusion, the pulse pressure difference typically decreases, especially the gap between diastolic and systolic pressures. This is because pericardial effusion can weaken the contractility of the heart chambers, leading to either decreased diastolic pressure or increased systolic pressure, thus reducing the pulse pressure difference. If pericardial effusion is timely addressed and corrected, this condition can improve. Currently, it is recommended that patients actively monitor changes in blood pressure. If there is a history of hypertension, it is necessary to actively use antihypertensive medications to treat and control this condition.

What is the cause of pericardial effusion with persistent high fever?

If the patient presents with pericardial effusion and experiences elevated body temperature, it may indicate the presence of an infection, suggesting that the symptoms are worsening. Currently, the treatment for pericardial effusion primarily involves puncture, fluid extraction, and laboratory analysis. If the pericardial effusion is severe or abundant, fever may occur. Since fever is an indicator of inflammation, it is necessary to use antibiotics for active treatment in order to control this condition. If the body temperature continues to rise, sometimes it is also necessary to use antipyretic drugs to alleviate the symptoms. Persistent high fever indicates that the condition has become very serious, signaling that the infection indices are extremely severe.

Will pericardial effusion cause an increase in troponin levels?

In general, if a patient is diagnosed with pericardial effusion, troponin levels might also increase under stress conditions. This is because troponin is primarily used as a marker to assess myocardial infarction. An increase in troponin levels suggests the possibility of a myocardial infarction. However, under stress conditions, especially with pericardial effusion, troponin levels can rise. During this period, it is also advisable to perform an electrocardiogram or a cardiac echocardiography on the patient for a more definitive diagnosis. A mere increase in troponin levels does not conclusively indicate a problem; it is necessary to consider the patient’s current symptoms and results from other diagnostic tests.

What position should be taken for pericardial effusion?

If the patient is diagnosed with pericardial effusion, it is generally recommended that the patient remain in a semi-recumbent position, or with legs dangling, to reduce cardiac load and improve symptoms. This is because the main complication of pericardial effusion is the occurrence of myocardial ischemia, or myocardial necrosis. Additionally, the primary treatment for pericardial effusion is still based on pericardiocentesis to improve cardiac function. During this period, it is also essential to actively monitor changes in the patient's blood pressure. If the patient's blood pressure is too high, antihypertensive medications should be used. Generally, a semi-recumbent position is still recommended for patients with pericardial effusion.
