What is epidural anesthesia, clear mind?

Epidural space block anesthesia, that is, injecting local anesthetic into the epidural space to block the spinal nerve root, temporarily paralyzing its innervated area, is called epidural space block anesthesia, or epidural block for short.

During epidural anesthesia, the patient is awake.

Indications: In theory, epidural blocks can be used for any procedure except the head. However, from a safety point of view, epidural block is mainly used for operations on the abdomen and below, including urinary, obstetrics, and lower extremity operations. Neck, upper limbs and chest can be applied, but management is complicated. High-position epidural is mainly used for postoperative analgesia or general anesthesia combined with epidural anesthesia to reduce the amount of general anesthesia. In addition, epidural anesthesia can also be used for any operation suitable for subarachnoid block. It is also used for postoperative analgesia.

Contraindications: 1. Patients with hypovolemia and shock; 2. Patients with puncture site infection or bacteremia that can cause epidural infection; 3. Patients with hypocoagulable state, and those who have not stopped using anticoagulant drugs for a long time recently; 4. Patients with postoperative trauma, deformity at the puncture site, those with lower back pain that may aggravate after anesthesia; 5. Patients and their families who have concerns; 6.
