Consequences of Cardiac Arrests during Spinal Anaesthesia

Spinal anaesthesia has been used for more than a century and is considered as a relatively simple and safe technique. Occasionally unexpected bradycardia and/or asystole may develop during the administration of spinal anaesthesia in apparently healthy and young patients. These situations are often attributed as the consequence of mismanagement of the spinal technique and not due to an intrinsic...

Sedation during spinal anaesthesia in infants.

BACKGROUND Neuraxial anaesthesia in adults decreases the dose of i.v. or inhalational anaesthetic needed to reach a desired level of sedation. Furthermore, spinal anaesthesia alone has a sedative effect. The mechanism behind this phenomenon is presumed to be decreased afferent stimulation of the reticular activating system after sympatholysis. We hypothesized that this mechanism is equally acti...

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...

Haemodynamic effects of three doses of dihydroergotamine during spinal anaesthesia.

We performed a randomized study comparing the haemodynamic effects of three doses of the vasopressor dihydroergotamine (DHE) (5, 10 and 15 microg x kg(-1)) in 30 ASA 1 and 2 patients, aged 53-87 yr, undergoing spinal anaesthesia. Non-invasive systolic arterial pressure (SAP), heart rate and central venous pressure (CVP) were recorded continuously for 25 min. Intravenous fluids were withheld dur...
