In clinical practice, the nursing measures for venous thrombosis mainly include the following aspects: i. The patient’s peripheral circulation of the limb should be observed, such as the patient’s skin color, temperature, pain, swelling, numbness, the presence of arterial pulsation, abnormal sensation, and venous filling. Second, the circumference of the patient’s limbs should be measured and recorded regularly. Third, special attention should be paid to the patient’s complaints, for example, if the patient complains of chest tightness and difficulty in breathing, the patient should be reported to the doctor in time, and the patient’s vital signs should be closely observed at this time to prevent pulmonary embolism. Fourth, attention should be paid to observe whether the patient will have adverse drug reactions. Generally speaking, for patients using anticoagulant and thrombolytic drugs, the patient’s bleeding should be strictly observed, for example, the patient’s whole body skin, oral cavity, nasal cavity, wounds, hematuria and black stool should be regularly observed, which is safe for the patient.
