Epidural needle problem

Epidural anesthesia is a regional nerve block anesthesia. By injecting local anesthetic drugs into the epidural space to block the spinal nerve of a specific segment, in order to achieve a specific area of painless anesthetic effect. The anesthesia method has low requirements for hospital equipment and is easy to complete under simple medical conditions, so it is widely used in our country. However, the disadvantages of this kind of anesthesia are also obvious, that is, the anesthesia is not perfect enough, especially the pulling reaction of some visceral nerves cannot achieve satisfactory results. As a result, the patient may have some discomfort of different degrees during the operation, and the anesthesiologist will use sedative and analgesic drugs to relieve the discomfort caused by this pulling reaction. In epidural anesthesia for Caesarean section patients, sedative and analgesic drugs are not used as much as possible because of the fetal considerations, as these drugs can cause problems such as respiratory depression after delivery, and this should be one of the reasons that patients think that the effect is not good. In addition, pregnant women because of pregnancy, will lead to epidural vascular dilation, affecting the spread of anesthesia drugs, which is also one of the reasons why many pregnant women under epidural anesthesia caesarean section effect is not good. In addition, the effect of epidural anesthesia depends on the diffusion of anesthetic drugs in the epidural space. Some people may have some specific conditions in the epidural space that affect the diffusion of anesthetic drugs, such as malformation and epidural mediastinum, which will be one of the reasons for poor anesthetic effect. There are many other causes of bad anesthesia is not a list of reasons, of course, it is undeniable that the technical level of the anesthesiologist is also one of the reasons for bad anesthesia.
