Abstract:
The analysis of morphological and histoezymological changes of spinal cord neurons has been performed in outbred dogs following epidural infusion of isobaric 2% lidocaine solution. In the control group the animals received epidural infusion of 0.9% saline. The results obtained indicate the absence of pathological structural and metabolic changes in the nervous tissue after lidocaine application. Certain signs of morpho-functional reorganization were noted in spinal cord neurons of animals in both experimental and control groups. The registered changes were found to vary within the physiological fluctuation limits and are rather indicative of the functional reaction of the studied structures of the nervous tissue to the epidural injections of either saline and lidocaine.

Local Anesthetics: Clinical Application as Epidural Anesthesia
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Local Anesthetics: Mechanism of Action
Local anesthetics are amphiphilic molecules consisting of a hydrophobic aromatic part linked to a hydrophilic group by an ester or amide linkage. They are weak bases and are usually available as salts, which increases their solubility and stability. Once administered, LAs exist in the body either...
