Causes of perforated dura mater: including both operational factors and patient factors

(1) Operational factors

1. Epidural block is a kind of blind puncture. For beginners, due to the inexperience of acupuncture at different levels of the intervertebral ligament, it is inevitable that the puncture will occur;

2. The anesthesiologist inserts the needle too fast during puncture, or suddenly slips in when encountering bone;

3. It is inappropriate to use instruments and appliances; the catheter is too hard, which increases the possibility of perforating the dura mater and is not easy to be found.

2) Patient factors

1. After receiving epidural block many times, due to repeated trauma, bleeding or chemical stimulation of drugs, the epidural space is narrowed due to adhesion, or even atresia, and the puncture needle can often penetrate the dura after passing through the ligamentum flavum;

2. Spinal deformity or disease; huge intra-abdominal mass or ascites; the spine is not easy to bend, causing difficulty in puncture; repeated exploratory puncture may puncture the dura mater;

3. The calcification of the ligament in the elderly often slips into the subarachnoid space after passing through the ligamentum flavum, so the perforation rate of the elderly is higher than that of the young;

4. There are reports of repeated puncture and puncture due to the thin congenital dura;

5. Because the epidural space in children is narrower than that of adults, the operation is more difficult, and it is often necessary to operate under general or basic anesthesia, and it is easier to penetrate the dura.
