Pulmonary embolism is a pathological process in which a blood clot in the vessels detaches, affecting the pulmonary artery and its branches. After the occurrence of a pulmonary embolism, patients generally visit the respiratory medicine department. Clinically, a pulmonary artery CTA can be performed to further confirm the diagnosis. The treatment methods in clinical practice are mainly as follows: If the patient experiences circulatory disturbances, emergency thrombolytic therapy may be considered; if the patient's circulation is stable, treatment with low molecular weight heparin and warfarin anticoagulation can be considered. Of course, it is important to monitor the patient's respiration and blood pressure.

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.

How long does the treatment for pulmonary embolism take?

The timing of pulmonary embolism treatment mainly depends on the severity of the pulmonary embolism. The main goals of pulmonary embolism treatment are to save lives by addressing life-threatening right heart dysfunction and obstructive shock caused by the pulmonary embolism, to re-establish pulmonary vascular patency, restore lung tissue perfusion, and prevent the recurrence of pulmonary embolism. Main treatment methods include: respiratory and circulatory support, anticoagulation, thrombolysis, interventional or surgical removal of blood clots, placement of inferior vena cava filters, etc. General management: Patients who are highly suspected or diagnosed with pulmonary embolism should be closely monitored, tracking changes in respiration, heart rate, blood pressure, venous pressure, electrocardiogram, and blood gases to prevent the dislodgement of clots again. Absolute bed rest is required, and care should be taken not to overly bend the lower limbs, maintain bowel regularity, and avoid straining. For patients experiencing anxiety and panic symptoms, reassurance should be provided, along with appropriate use of sedatives. If there is chest pain, analgesics may be administered. For symptoms like fever and cough, corresponding symptomatic treatments should be given. To prevent lung infections and treat phlebitis, antibiotics may be used. Additionally, support treatments for respiratory and circulatory functions, as well as anticoagulation therapy, should be provided.

Can pulmonary embolism result in a vegetative state?

After a pulmonary embolism, if it is an acute and extensive embolism and not treated promptly, it can lead to severe hypoxemia. If hypoxemia is not addressed quickly and persists, it will affect the oxygen supply to vital organs throughout the body, including the brain. The brain is the organ most vulnerable to oxygen deprivation. If there is complete lack of oxygen for just four minutes, irreversible damage occurs to the cerebral cortex, and the patient will not wake up, leading to a vegetative state. Therefore, in cases of acute extensive pulmonary embolism, if treatment is delayed, there is a significant risk of the patient entering a vegetative state, and the mortality rate is also very high. Many patients may experience sudden death.

Is there a lot of phlegm in pulmonary embolism?

Pulmonary embolism is a relatively common acute disease in clinical practice. It usually occurs when blood clots from the veins in the legs or pelvis detach, travel through the bloodstream to the pulmonary arteries, and cause an embolism. The onset of this disease is often very sudden. Due to different triggers, the clinical symptoms vary. Typical symptoms of pulmonary embolism include difficulty breathing, chest pain, coughing up blood, and coughing. Coughs are often dry, and patients may also have a small amount of white sputum. Some patients might even experience wheezing and other clinical symptoms. Therefore, the occurrence of excessive sputum is rare in patients with pulmonary embolism.

What are the symptoms of a pulmonary embolism warning sign?

Pulmonary embolism is also very common in clinical settings, mainly seen in patients who have been bedridden for a long time, undergone various major surgeries, suffered from long bone fractures, pregnancy, etc. In the early stages of pulmonary embolism, patients generally experience varying degrees of chest pain, hemoptysis, and difficulty breathing, among others. If pulmonary embolism is suspected and the patient's condition permits, a pulmonary artery CTA scan should be immediately carried out to further confirm the diagnosis of pulmonary embolism. If the pulmonary embolism has already caused circulatory disturbances, thrombolytic therapy should then be considered.
