Failed spinal anaesthesia

REVIEWARTICLE Failed spinal anaesthesia: mechanisms, management, and prevention

Although spinal (subarachnoid or intrathecal) anaesthesia is generally regarded as one of the most reliable types of regional block methods, the possibility of failure has long been recognized. Dealing with a spinal anaesthetic which is in some way inadequate can be very difficult; so, the technique must be performed in a way which minimizes the risk of regional block. Thus, practitioners must ...

Spinal anaesthesia.

Spinal anaesthesia is normally performed by puncture of the dura and arachnoid mater in the lumbar region, and local anaesthetic is introduced directly into the eerebrospinal fluid (CSF) surrounding the nerve roots and spinal cord. The solution will spread longitudinally through the CSF and the drug will be taken up by the neuronal tissue. Whether an effective concentration results in a particu...

Spinal Anaesthesia in Spinal Surgery

Bupivacaine concentrations in lumbar cerebrospinal fluid in patients with failed spinal anaesthesia.

BACKGROUND Spinal anaesthesia (SA) has high success rates. However, inadequate block after SA has been reported even in the absence of technical problems. Various mechanisms for failed SA (FSA) have been proposed, but reports of cerebrospinal fluid (CSF) concentrations of local anaesthetics (LA) after FSA are scarce. We report lumbar CSF concentrations of bupivacaine in 20 patients in whom adeq...

Spinal Anaesthesia – an Update

Because of its simplicity and high success rate spinal anaesthesia (SA) belongs to the most common used regional anaesthesia techniques. In many institutions it is regarded as a standard method for surgical procedures like C section, transurethral resection of prostate or femoral neck fracture in the elderly. Although used for more than a century, much has been learned in the last two decades r...
