Epidural needle anesthesia procedure

Epidural anesthesia should first open the venous access after the patient enters the operating room, connect the conventional blood oxygen, blood pressure and ECG monitoring, and observe the patient's heart rate and blood pressure. The patient is changed from supine to lateral position, the head and knees are curled to the middle, and the thighs are as close to the abdomen as possible. The puncture needle passes through the skin, subcutaneous, supraspinous ligament, interspinous ligament, and ligamentum flavum in turn, and reaches the epidural space. At this time, you can often feel the feeling of the syringe being pushed out, insert the epidural catheter, and withdraw the puncture needle. Indwelling in the epidural space, after fixing the catheter, the patient can be turned into a supine position, and the drug can be administered in batches through the catheter. First, give a test dose of 3-5ml, observe whether the patient has general spinal anesthesia, etc., then give the full amount of epidural drugs, measure the anesthesia level, and start the operation when the anesthesia level reaches the surgical demand.
