Introduction
Indications for deep venous catheterization include: transfusion and fluid resuscitation in hemorrhagic shock; long-term intravenous therapy, during which this method can reduce vascular irritation; and postoperative chemotherapy for cancer patients to alleviate discomfort. Contraindications: patients with bleeding tendencies, skin infections, or heart disease should not undergo deep venous catheterization to avoid adverse outcomes.
Indications for deep venous catheterization include hemorrhagic shock, long-term intravenous therapy, and malignant tumors. Contraindications include bleeding tendencies, local skin infections, and heart disease.
I. Indications
1. Hemorrhagic Shock
When hemorrhagic shock occurs, peripheral blood vessels may collapse; therefore, deep venous catheterization can be used to administer blood transfusions and intravenous fluids, helping to stabilize the patient's condition.
2. Long-Term Intravenous Therapy
For patients requiring prolonged intravenous treatment, repeated infusions can cause significant vascular irritation. Deep venous catheterization helps reduce this irritation.
3. Malignant Tumors
Patients with malignant tumors often require chemotherapy after surgery. If they cannot tolerate the irritating effects of chemotherapeutic agents on peripheral veins, deep venous catheterization can be used to alleviate discomfort during treatment.
II. Contraindications
1. Bleeding Tendency
Patients with a tendency to bleed have impaired coagulation function. During deep venous catheter placement, puncture procedures may lead to bleeding or oozing at the site.
2. Local Skin Infection
If a patient has a local skin infection, performing deep venous catheterization may increase the risk of infection and hinder recovery.
3. Heart Disease
Patients with heart disease may experience symptoms such as palpitations, shortness of breath, and dyspnea. Performing deep venous catheterization during such periods may precipitate heart failure, making it difficult to control their condition.
If deep venous catheterization is being considered, patients should consult a qualified physician who can assess individual circumstances and determine whether the procedure is appropriate.
