Epidural needle problem

Epidural anesthesia is a type of regional nerve block anesthesia. It is an anesthetic method by injecting local anesthetic into the epidural space to block the spinal nerve of a specific segment to achieve painless anesthetic effect in a specific area. This method of anesthesia has relatively low requirements on hospital equipment and is easy to be completed under simple medical conditions, so it is widely used in China. But is also very obvious disadvantage of the anesthesia, anesthesia is not perfect, especially the pull of some of the splanchnic nerve reactions cannot achieve satisfactory effect, as a result, patients in surgery may have some different degree of discomfort, anesthesia in anesthesia doctor will use of sedation and analgesia drug to relieve the force response the effects of stress. In the epidural anesthesia of caesarean section patients, because of the factors of the fetus, so try not to use sedative and analgesic drugs, because these drugs can cause problems such as respiratory depression after delivery of the fetus, this should be one of the reasons patients think the effect is not good. In addition, due to pregnancy, pregnant women will lead to the dilation of blood vessels in the epidural space and affect the diffusion of anesthetic drugs, which is also one of the reasons why many pregnant women have a poor effect of caesarean section under epidural anesthesia. 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 the poor effect of anesthesia. There are many other causes of bad anesthesia will not be listed, of course, there is no denying that the level of anesthesiologist's technology is also one of the reasons for bad anesthesia.
