Postoperative bone marrow puncture

1. After operation, the patient should be told to lie still and rest. At the same time, markers should be made and bone marrow tablets should be sent for examination.

2. Draw bone marrow and smear quickly to avoid coagulation. Peripheral blood smears should be taken as a control. Although medullary puncture is an invasive examination, it does not cause great damage to the body and does not require special care because of its simple operation, less extraction of bone marrow fluid and little pain to the patient. The following measures should be taken after examination for those with weak constitution and bleeding tendency. 1. Hemostasis: generally hemostasis by compression. 2. Bed rest: After examination, there will be mild pain in the puncture area. The patient can return to normal after a day of bed rest and restriction of physical activity. 3. Prevent infection: Local tissue should be strictly disinfected during puncture. Keep the puncture area clean and dry, and replace the covering gauze when it is wet with blood or sweat. When the pinhole is red, swollen, hot and painful, 2% iodine TINCture or 0.5% iodine volt can be applied locally, 3-4 times a day. If accompanied by systemic fever, you should contact your doctor, according to the appropriate choice of antibiotics.
