Continuous bladder irrigation. (1) Keep bladder flushing at all times and stop flushing only when the physician agrees to stop. The flushing fluid does not need to be replaced by the nurse in time, and the flushing bucket is full in time for the nurse to handle it. (2) Observe the color of the flushing fluid. If the color is dark (thick blood color), you need to speed up the flushing speed. If the color is lighter (light blood color), flush more slowly. (3) Pay attention to the basic consistency of the flushing fluid in and out speed as normal, if only in and out, the urinary catheter is blocked, need to properly pinch the drainage tube, may be clot blockage, if there is no relief, need to promptly find a doctor or nurse to deal with. Urinary catheter traction. Usually the urinary catheter is traction on one leg, and the leg in traction cannot move too much. It can only be moved when the traction is released. Massage of both lower extremities. Both thighs and calves need to be massaged, with firm pressure, massaging the muscles and reaching under the legs to massage. The patient is massaged for about 10 minutes every 1-2 hours while awake. This can prevent thrombosis of the lower limbs and prevent pulmonary embolism. If there is phlegm it needs to be coughed up promptly. Consult your doctor or nurse for other questions.
