Epidural needle anesthesia contraindications

1. Patients with shock and hypovolemia cannot choose epidural anesthesia, which will worsen the condition;

2. Infection at the puncture site, and patients with bacteremia and sepsis cannot undergo epidural anesthesia;

3. The patient's coagulation function problems. In a hypocoagulable state, platelets are reduced, and the clotting time is prolonged. Epidural anesthesia cannot be performed, because during epidural puncture, blood vessels may be damaged and hemorrhage. After the amount of bleeding is large, an epidural hematoma will be formed. Compression of nerves leads to paraplegia, so epidural anesthesia cannot be performed;

4. Epidural anesthesia requires puncture between the vertebral bodies. If the spine is deformed or has undergone surgery or trauma, especially low back pain, low back pain, lumbar disc herniation, it is not suitable for epidural anesthesia;

5. Patients who do not cooperate are also not suitable for epidural anesthesia. For example, some elderly patients have Alzheimer's disease. This situation does not cooperate at all, and children do not cooperate. In this case, it is not suitable for epidural anesthesia in a awake state. If you must do epidural anesthesia, you need to perform an epidural puncture under general anesthesia.
