What is total spinal anesthesia?

Whole spinal anesthesia epidural anesthesia is one of the most serious complications, mainly because the epidural puncture needle into the subarachnoid space and is not found, because of epidural anesthesia for local anesthetics greater than the amount of subarachnoid anesthesia, so injection through a large number of local anesthetics to enter subarachnoid gap and cause the whole spinal anesthesia. The patient may experience apnea, a drop in blood pressure, and even loss of consciousness within minutes. If the patient is found late or improperly managed, it may cause cardiac arrest. Total spinal anesthesia is the most serious complication of epidural anesthesia. Once total spinal anesthesia occurs, artificial respiration should be performed immediately, intravenous infusion and vasoconstrictor should be accelerated to maintain normal blood pressure, and cardiopulmonary resuscitation should be performed immediately in case of cardiac arrest. Prophylactic measures include infusion of drugs through epidural catheterization should be pumped back without cerebrospinal fluid reflux before infusion; The experimental dose of 3 ~ 5ml was first given and observed for 5 ~ 10 minutes. If no local anesthetic was mistakenly injected into the subarachnoid space, the injection was continued.
