Pulmonary embolism
Does pulmonary embolism cause vomiting?
Vomiting is not a typical clinical manifestation of pulmonary embolism. For pulmonary embolism, typical symptoms generally include chest pain, coughing up blood, and difficulty breathing. Some patients may show atypical symptoms such as unexplained difficulty breathing, unexplained drops in blood pressure, fainting, and other related conditions. Additionally, some patients may exhibit arrhythmias. When the condition of a patient with pulmonary embolism becomes severe, it may be accompanied by significant respiratory failure or shock. In such cases, symptoms of vomiting might also be present. However, if there is just vomiting, the likelihood of pulmonary embolism is generally considered low, and other causes should be investigated first, such as gastrointestinal disorders.
The difference between pulmonary embolism and pulmonary edema
The difference between pulmonary embolism and pulmonary edema lies in their mechanisms of onset, clinical manifestations, and treatments; they are completely different diseases. Pulmonary embolism primarily occurs when thrombi from the inferior vena cava or superior vena cava, or other emboli, travel with the bloodstream to the right heart and then block the pulmonary artery. The symptoms mainly include coughing, chest pain, difficulty breathing, and coughing up blood. On the other hand, pulmonary edema is mostly due to left heart dysfunction, caused by coronary artery disease or acute heart failure, leading to the inability of the pulmonary blood to return to the left heart. This results in an excessive retention of blood in the lungs, causing edema in the alveoli and interstitial space of the lungs. The symptoms are primarily characterized by difficulty breathing, coughing, and pink frothy sputum. The treatments for the two are also entirely different: pulmonary embolism is primarily treated with thrombolysis, while pulmonary edema is mainly treated by correcting heart function. Thus, it is crucial to differentiate between these two diseases.
The difference between pulmonary embolism and chronic obstructive pulmonary disease.
The differences between pulmonary embolism and chronic obstructive pulmonary disease (COPD) mainly include the following aspects: 1. Different mechanisms of onset: Pulmonary embolism refers to the blockage of the pulmonary arteries by thrombi, while COPD is a disease of the small airways, primarily characterized by the narrowing of these airways. 2. Different clinical manifestations: Pulmonary embolism is often acute, with symptoms such as chest tightness, difficulty breathing, and may also include chest pain, coughing up blood, and fainting. COPD is a chronic disease, usually presenting with chronic chest tightness and difficulty breathing, and may also include symptoms such as coughing and expectoration. 3. Different diagnostics: Pulmonary embolism can often be diagnosed through CT pulmonary angiography, whereas COPD typically requires lung function tests for diagnosis.
What should I do if my leg swells after a pulmonary embolism?
After a pulmonary embolism, swelling in the legs can occur, and this situation is very likely secondary to right heart dysfunction following the pulmonary embolism. At this time, the main treatment should focus on the pulmonary embolism. The mechanism of pulmonary embolism mainly involves thrombi from the venous system, which travel with the blood flow to the right heart and then are lodged in the pulmonary artery, causing a sudden increase in the load on the right heart and leading to right heart failure. Consequently, the blood flow from the superior and inferior vena cava cannot return to the right heart. If the blood flow in the inferior vena cava is blocked peripherally, it can cause swelling in the legs. Therefore, the primary focus should still be on treating the underlying disease, by using anticoagulants or thrombolytic therapy. Swelling in the legs can also be alleviated with diuretics, but it is crucial not to move the lower limbs carelessly, as there might still be thrombi present, and moving the limbs could lead to the dislodgment of new thrombi.
Early symptoms of pulmonary embolism
In the early stages of pulmonary embolism, symptoms such as difficulty breathing, chest tightness, shortness of breath, and decreased oxygen saturation can occur. Early signs may include chest pain, as chest pain is often an initial symptom of pulmonary embolism. Sometimes the pain can be severe, and some patients may experience coughing, dry cough, and even cough up blood. There may also be symptoms of short exhalation and difficulty breathing, especially in patients with main trunk blockages, where the difficulty in breathing can be very pronounced. In more severe cases, some may experience fainting, suddenly collapsing while walking.
Can a pulmonary embolism cold cause a fever?
Pulmonary embolism combined with a cold can indeed cause a fever, which is a relatively common occurrence. However, it typically results in a low-grade fever. Additionally, it is important to note that if pulmonary embolism is combined with pulmonary infarction, it can also lead to a fever, usually manifesting as a low-grade fever. Therefore, pulmonary embolism itself can potentially cause a fever. Furthermore, it is crucial to be aware that if pulmonary embolism leads to a fever, it should not be misdiagnosed as a common cold or pneumonia. Especially in patients with concurrent pulmonary infarction, the presence of a fever, and subpleural patchy shadows seen on chest CT can resemble the manifestations of pneumonia. Care must be taken to avoid misdiagnosis as pneumonia, which could delay treatment for the patient and potentially lead to severe consequences.
Can a secondary recurrence of pulmonary embolism be treated?
Pulmonary embolism, even if it recurs for the second time, is treatable, but the approach should differ from the first recurrence. It's vital to determine the cause of the pulmonary embolism, although many patients with this condition do not have an identifiable cause. For such patients, long-term oral anticoagulants might be recommended. With long-term use of oral anticoagulants, the likelihood of thrombosis, especially in the venous system, significantly reduces. This means that the chance of recurrence in patients also decreases considerably. However, if the cause can be identified, it is better to address and eliminate it. For instance, if the cause is long-term use of oral contraceptives or the presence of varicose veins, these primary or secondary factors should be resolved. The treatment should not just focus on anticoagulation or thrombolytic therapy, as there could still be a possibility of a future pulmonary embolism recurrence.
The difference between pulmonary embolism and pulmonary congestion
Pulmonary embolism and pulmonary congestion are two completely different diseases. Pulmonary embolism is mainly caused by the thrombosis of the venous vessels entering the pulmonary artery, thereby causing restricted blood flow in the pulmonary artery and leading to pulmonary embolism. Pulmonary congestion is often due to left heart failure, where the blood flow in the lungs cannot return to the left heart, causing the blood to be retained and congested in the lungs, forming this disease. However, they do have some similarities, such as presenting symptoms of difficulty breathing, shortness of breath, low blood pressure, shock, etc. But through diagnosis and additional examinations, these two diseases can be clearly differentiated. Therefore, careful differentiation is required in clinical practice because the treatments for the two diseases are completely different. If misdiagnosed, the treatment could be incorrect, leading to serious consequences from mistreatment.
Can acute pulmonary embolism be cured by anticoagulation?
Anticoagulation has a partial curative effect on acute pulmonary embolism. Based on the area of the embolism and the patient's vital signs, it is classified into mild, moderate, and severe pulmonary embolism. If it is a mild to moderate pulmonary embolism, anticoagulation can completely cure it, because anticoagulation can help the body's fibrinolytic system remove the blood clots that have already formed, and it can also prevent new clots from forming. However, in cases of severe pulmonary embolism, especially when the patient presents unstable vital signs and is in life-threatening condition, it is not advisable to rely solely on anticoagulant therapy. This is because the effect of anticoagulant treatment is relatively slow, and it requires a certain amount of time for the body's immune and fibrinolytic systems to clear the embolism. Therefore, at such times, thrombolytic treatment is recommended. Of course, this requires an experienced physician to assess the patient's vital signs and overall condition.
Can I eat lamb if I have pulmonary embolism?
Patients with pulmonary embolism can appropriately eat mutton, as it is acceptable in their case. For pulmonary embolism, it is advocated to follow a light diet, avoiding spicy, irritating food, and excessively greasy food to prevent aggravating the gastrointestinal burden of the patient. Additionally, it is acceptable for patients with pulmonary embolism to consume some meat, as long as it is not fatty meat. Once diagnosed with pulmonary embolism, patients should receive active treatment, which often requires anticoagulant therapy. If the condition is not too severe, simple anticoagulant treatment may allow the patient’s condition to recover. However, if the pulmonary embolism is more severe, thrombolytic therapy may be necessary. After thrombolytic treatment, vascular anticoagulant therapy is given to manage the patient's condition.
