Which Is More When The Lumbar Anesthesia Needle Or The Combined Spinal Anesthesia Needle Is Injected
Nov 17, 2022
spinal anaesthesia is the abbreviation of subarachnoid anaesthesia and spinal anesthesia, which refers to the injection of local anesthesia drugs into the subarachnoid space through the lumbar interstitial space, blocking the conduction function of some spinal nerves and causing anesthesia in the corresponding innervated areas.
Combined anesthesia of lumbar anesthesia and epidural anesthesia (CSEA) has been widely carried out in clinical practice. It is generally necessary to use the special puncture instrument kit supplied by the market. The method of "needle within needle" is adopted, and the injection of the drug under lumbar anesthesia (SA) and the standby epidural catheter (EA) for drug injection.
In fact, now the lumbar anesthesia and combined lumbar epidural anesthesia belong to a class of anesthesia, and can almost be said to be a kind of anesthesia
The difference is,
The first is that the procedure is different. Simple lumbar anesthesia is just an injection of a drug into the subarachnoid space
The method of needle - in - needle is used for lumbar - epidural anesthesia
In the second lumbar epidural anesthesia, in order to meet the requirements of surgery, a catheter will be placed in the epidural space in many cases. When the operation time is too long and the anesthesia level drops, anesthesia will be injected into the epidural space from the catheter to extend the anesthesia time and the anesthesia level.
