With the widespread use of computed tomography (CT) and 3D processing software technology in clinical treatment, the requirements for the quality and clarity of imaging images are also increasing, and the application of contrast agents is becoming more and more common. And in CT enhanced scanningHigh pressure syringes are the main means of contrast agent infusion, which can ensure the quality and clarity of images, accurately diagnose the nature of lesions, and effectively help clinical judgment of disease progression.

The application of high-pressure injectors in clinical enhanced scanning is becoming increasingly common, butIf the operation is not standardized, it will increase skin allergies, air embolismPhlebitisIt is very important to take relevant care before using a high-pressure injector to inject contrast agent in case of adverse reactions.

nursing

1、 Before the examination, conduct an iodine allergy test and inquire in detail whether the patient has a history of allergies. Injecting dexamethasone before the enhanced scan can reduce the incidence of allergic reactions.

2、 Do it wellmental nursing Eliminate patients' tension and fear towards injecting contrast agents, so that they can better cooperate with the examination.

3、 When puncturing blood vessels, it is necessary to choose veins with good elasticity and thick and straight lines. Due to the fast injection speed and high pressure of high-pressure injection, it is advisable to avoid puncturing near the joints and fix them properly. If the patient feels pain or swelling in the local area, it should be re punctured. Keep the injection tube unobstructed, fasten the connecting tube tightly, and prevent it from collapsing under high pressure.

4、 Strictly grasp the indications andcontraindicationDevelop prevention and rescue measures, prepare emergency drugs and equipment, and provide timely and targeted treatment for those who experience shock or circulatory failure. If necessary, take appropriate measuresTracheal intubationRescue measures such as tracheotomy and intubation.

In addition to the nursing work that CT room staff need to consider above, there is another point that needs special attention when using high-pressure injectors, which is to preventAir embolismIt can seriously endanger the patient's life. This requires the staff toBefore injection, exhaust the air from the syringe and keep the needle down to prevent air bubbles from entering the blood vessels; At the same time, pay attention to controlling the injection volume, and there should be 1~2mL of residual medication in the syringe after injection.

In short, the quality of nursing work can affect the quality of images and diagnostic results. Therefore, CT room nursing staff should have a rigorous work attitude and sense of responsibility in their work, master the use and precautions of high-pressure syringes, and pay attention to accumulating nursing skills and experience. They should also standardize the operation during injection, pay attention to early allergic reactions, and ensure patient safety.
