Micro pump infusion, you need to pay attention to these
1. Ensure the smoothness of the pump injection pipeline: When using micro-pump to pump drugs in nursing work, the smoothness of the pump injection pipeline should be observed frequently to avoid pressure, discount and blood return of the pump injection pipeline, especially after changing the body position, pipeline and injecting drugs through three links. Such as the application of booster drugs, unexplained blood pressure drop, increase the drug pump speed is still no effect, should consider the possibility of pump tube blockage, not because the micro pump did not alarm and ignore this factor. Check whether the micro pump pipeline is blocked in time, keep the infusion path smooth, and report to the doctor. Some studies have said that when the input speed of the micro-pump is lower than 5 ml/h, it is easy to block the tube. Normal saline or glucose solution must be input at the same time. Maintaining at the speed of 5 drops/min will neither cause adverse reactions nor increase the heart load, which can effectively prevent blood return.
2. Prevent drug extravasation: strengthen inspection, pay close attention to the color of the local skin, and observe whether there is swelling. In case of extravasation, the infusion should be stopped immediately, the puncture site should be replaced, and the affected limb should be raised, and local symptomatic treatment should be given: the light one should be wet with 25% magnesium sulfate, and the heavy one should choose the treatment method according to the different extravasation liquid.
3. Prevent venous blood return: When blood return occurs in the pipeline, different measures should be taken according to the nature of the drug and the amount of blood return. Do not push the stock solution into it quickly. Some researchers recommend to connect the syringe filled with normal saline to the needle and push back the blood slowly. When a blood clot occurs, it can be drawn out with a 1ml syringe, and under the condition of ensuring smooth pipeline, the tube is flushed with normal saline. If the suction does not work, the tube must be extubated again. If the amount of blood returned is large (such as blood returned to the extension tube), the extension tube should be replaced in time.
4. Standardized connection and clear identification: indicate the bed number, name, drug name, dosage, speed, time, etc. on the syringe, and design different color identification for different pharmacological effects of drugs pumped by micro-pump. The application of pipeline identification can standardize the work flow of nurses, strengthen the awareness of nursing risk, reduce nursing errors, and ensure the quality of nursing.
5. Strictly implement the shift change system for vasoactive drugs: do a good job in shift change, and achieve "three cleannes", I .e. speak clearly, write clearly and see clearly at the bedside, so as to prevent errors and accidents. Type, dose and concentration of vasoactive drugs. Check whether the passage is unobstructed, whether the joint is tightly connected, whether the drug is used according to the principle of vasoactive drug use, and whether there is drug extravasation. The successor recorded in detail the drug concentration of vasoactive drugs entering the body every minute on the record sheet, and recorded the replacement of vasoactive drugs.
6. Do a good job of education for patients and their families, inform the purpose of using micro-injection pump and matters needing attention, eliminate their tension, and cooperate with treatment.
7. Properly fixed. The micro pump should be fixed on the infusion stand and should not be placed on the bedside table or bed to avoid slipping and damaging the machine.
8. Strengthen the study of drug pharmacological knowledge, including drug usage, dosage, route, pharmacological effects, adverse reactions, incompatibility.
9. For patients whose blood pressure fluctuates when replacing vasoactive drugs, it is recommended to adopt the method of alternately replacing liquid medicine with double pumps. The specific process is as follows: replace liquid medicine-connect the front tube of the pump after the new syringe draws liquid medicine, exhaust all the air, and stick a mark for standby-take another micro injection pump, accurately install the syringe, connect the three links at the patient's end-the new pump starts to operate, after normal operation, open the three-way connection just connected-the original micro-pump is suspended, and the three-way connection of the original pump is closed-observe that the operation is normal and the hemodynamics of the patient has not changed. Close the original micro-injection pump and handle the materials.
