Precautions for intravenous infusion
1. Strictly implement aseptic operation to prevent complications; strictly implement the checking system to prevent errors.
2. For patients who need long-term infusion, attention should be paid to protecting the veins and using them rationally. Generally, starting with the small veins in the distal limbs.
3. Arrange the sequence of drug infusion in a planned manner according to the condition, medication principles, and drug properties. If you need to add drugs, you should pay attention to the incompatibility and make reasonable arrangements to achieve the treatment purpose as soon as possible.
4. The air in the infusion tube and needle must be drained before infusion. During the infusion, the liquid should be prevented from emptying. The infusion bottle should be replaced in time and the medicine solution should be added. The needle should be removed in time after the infusion to prevent air embolism. .
5. After inserting the needle, make sure the needle is in the vein before injecting the medicinal solution to avoid tissue damage. If drugs that are highly irritating to blood vessels need to be infused, they should be fully diluted and added after the puncture is successful. After the infusion, a certain amount of 0.9 sodium chloride solution should be added to protect the veins.
6. During the infusion process, inspections should be strengthened, patient complaints should be listened to patiently, the infusion situation should be closely observed, and attention should be paid to whether there are any local or systemic reactions, so that infusion failures and infusion reactions can be dealt with in a timely manner.
7. Keep the infusion set and medicinal solution sterile. If the infusion is continued for more than 24 hours, the infusion set should be replaced every day.
8. To prevent cross-infection, "one person, one towel, one belt" should be implemented, that is, each person has a treatment towel (or small pad) and a tourniquet.
9. Indwelling needles can generally be kept for 3 to 5 days, and no more than 7 days at most. Pay attention to protecting the corresponding limbs. Once blood is found in the needle tube, it should be flushed with heparin solution immediately to avoid clogging the lumen.
