What are the symptoms of postoperative thrombosis?

It is also common to cause blood clots after surgery. Patients often suffer from lower limb venous thrombosis, which can cause swelling and pain in the lower limbs and a local feeling of heaviness. At this time, the pain will worsen when walking or standing, which is quite harmful to patients. If you do not pay attention to timely treatment and prevention, it may also cause pulmonary embolism, which is a more serious manifestation of the disease.

What are the symptoms of postoperative thrombosis?

1. Venous thrombosis is a common thrombosis in clinical practice, usually caused by slow blood flow or congestion. The characteristics of venous thrombosis are that it contains a large number of red blood cells and fibrin, and the platelets show aggregation and degranulation changes, and their number is small; the thrombus looks like a whole blood clot in a test tube, and its color is dark red, and it is called a red thrombus. Venous thrombosis often causes occlusion of the vascular lumen, so the proximal end of the thrombus is mainly composed of red blood cells, and the tail end often has new platelets adhered to the surface.

Postoperative thrombosis prevention

1. For high-risk groups that are prone to deep vein thrombosis of the lower limbs, such as obese patients, patients with a history of lower limb trauma, the elderly, patients who are bedridden for a long time, and patients with hypertension and diabetes, a targeted plan should be developed based on the pre-operative evaluation. If necessary, blood-activating or anticoagulant drugs should be given as soon as possible, and coagulation function monitoring should be strengthened. 2. Strengthen postoperative care. If the patient needs to stay in bed, he should be turned over frequently in the early stage and encouraged to carry out activities in bed, such as deep breathing, effective coughing, frequent active activities of the feet and toes, and flexion and extension of the lower limbs, etc., to reduce venous blood stasis. High-risk patients should raise their lower limbs 20-30 degrees to promote blood return, and wear medical elastic stockings on their lower limbs if necessary. 3. Unless there are special circumstances, the patient should get out of bed and move around as soon as possible after surgery. Generally, he or she can sit up on the edge of the bed and move his or her limbs 2 to 3 days after surgery, and then gradually increase the amount of activity. 4. Strengthen dietary care. It is advisable to eat light, low-salt, low-fat foods rich in vitamins, high in protein and high in fiber to prevent constipation, so as to avoid increased intra-abdominal pressure due to difficulty in defecation and affect venous return in the lower limbs.
