The stimulatory effect of ornidazole and sodium chloride injection on blood vessels is relatively mild, but it may still have some impact on blood vessels in certain circumstances.

In clinical practice, to minimize the potential irritation to blood vessels, it is generally recommended to control the infusion rate of ornidazole and sodium chloride injection. For example, for a 100ml injection, the infusion time should typically not be less than 30 minutes. If the infusion rate is too fast, it may cause painful or tingling sensations due to blood vessel irritation.

Apart from direct irritation to blood vessels, ornidazole and sodium chloride injection may also cause other adverse reactions. These reactions may involve the digestive system (such as nausea, vomiting, abdominal pain, diarrhea, and other gastrointestinal discomforts), the nervous system (such as dizziness, headache, convulsions, drowsiness, confusion, and other symptoms), the blood system (such as decreases in white blood cells, platelets, and other blood cells), the respiratory system (such as cough, chest tightness, laryngeal edema, dyspnea, and other manifestations), and the circulatory system (such as palpitations, abnormal blood pressure, arrhythmia, and other conditions).

Furthermore, ornidazole and sodium chloride injection may cause allergic reactions, such as skin rashes, itching, systemic fever, and other symptoms, as well as phlebitis and abnormal skin changes at the site of administration.

Therefore, when using ornidazole and sodium chloride injection, patients should follow medical advice and observe their own reactions. If they experience persistent and unrelieved discomfort, they should seek medical attention promptly. At the same time, medical staff should also pay attention to controlling the infusion rate and observing the patient's reactions to ensure safe medication use.
