Coronary angiography, the full name of coronary angiography, is a special technique to send a special catheter to the coronary artery opening of the heart through the femoral artery of the thigh or the radial artery of the upper limb, and then inject contrast medium to develop the coronary artery. It is an important means to diagnose coronary heart disease, which can clearly show the anatomical structure, lesion location, lesion degree and lesion range of coronary artery. However, as an invasive test, coronary angiography also has certain risks, including possible postoperative complications, such as puncture site bleeding, infection, arrhythmia and so on. So, is anti-infective therapy needed after coronary angiography? The following is a detailed exploration of this issue.
1. Common complications after coronary angiography 1. Bleeding at the puncture site: Because coronary angiography requires puncture through the artery, bleeding or hematoma may occur at the puncture site after the operation. 2. Infection: Although coronary angiography is performed under strict sterile conditions, there is a risk of infection in any invasive procedure. If we do not pay attention to local nursing after operation, it may lead to bacterial infection at the puncture site. 3. Arrhythmia: Stimulation of contrast media, improper operation and other factors may cause arrhythmia. 4. Other complications, such as pericardial effusion, vasospasm, thrombosis and aneurysm, require timely medical intervention to avoid potential risks.
2. Application of anti-infective therapy after coronary angiography 1. Importance of preventing infection: Although infection after coronary angiography is not common, once it occurs, it may bring serious consequences to patients, such as aggravation of local inflammation, delayed wound healing, systemic infection and even septicemia. Therefore, the prevention of infection is particularly important in the nursing after coronary angiography. 2. Principle of anti-infective therapy: Anti-infective therapy after coronary angiography should follow the principle of “prevention first, treatment second”. That is to say, adequate skin preparation and disinfection should be done before operation, aseptic operation should be strictly observed during operation, local nursing and observation should be strengthened after operation, and anti-infective treatment should be carried out immediately once signs of infection are found. 3. Choice of anti-infective drugs: For infections that may occur after coronary angiography, broad-spectrum antibiotics can usually be chosen for prevention and treatment. The choice of specific drugs should be based on the specific conditions of patients, allergic history and bacterial culture results. Commonly used antibiotics include amoxicillin and cefuroxime sodium. However, it should be noted that the use of antibiotics should be carried out under the guidance of doctors to avoid abuse and misuse.
3. Nursing and
precautions after coronary angiography
1. Keep the puncture site clean and dry: The dressing should be changed regularly after the operation to keep the puncture site clean and dry and avoid contamination and infection. 2. Avoid strenuous exercise: Avoid strenuous exercise and overwork after operation, so as not to increase the burden of the heart and the injury of the puncture site. 3. Observe the changes of the patient’s condition: After the operation, we should closely observe the changes of the patient’s condition, including the changes of heart rate, blood pressure, body temperature and other indicators, as well as the signs of infection such as swelling and pain at the puncture site. 4. Reasonable diet and nutrition: After the operation, we should have a reasonable diet, strengthen nutrition, improve the body’s immunity, help to prevent infection and promote wound healing.
IV. Summary and Suggestions
To sum up, the need for anti-infective therapy after coronary angiography should be based on the specific conditions of patients. Although coronary angiography is performed under strict aseptic conditions, it is still important to prevent infection. Local nursing and observation should be strengthened after operation, and anti-infection treatment should be carried out immediately once signs of infection are found. At the same time, patients should also follow the doctor’s advice and guidance, reasonable diet, proper rest, avoid strenuous exercise, in order to promote physical rehabilitation and prevent the occurrence of infection.
