Total spinal anesthesia for what?

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. Patients may experience respiratory arrest, a drop in blood pressure, and even loss of consciousness within minutes, which can lead to cardiac arrest if not noticed or handled properly. Total spinal anesthesia is the most serious complication of epidural anesthesia. Once total spinal anesthesia occurs, artificial respiration should be performed immediately, infusion and intravenous vasoconstrictor injection should be accelerated to maintain normal blood pressure, and cardiopulmonary resuscitation should be performed immediately if cardiac arrest occurs. Preventive measures include epidural transcatheter injection should be withdrawn before injection without cerebrospinal fluid reflux before injection; The experimental dose of 3-5 ml was given first and observed for 5-10 minutes. If there was no manifestation of local anesthetic injection into subarachnoid space by mistake, the injection was continued.
