Summary
Epidural lidocaine did not cause pathological changes in dog spinal cord neurons. Observed functional rearrangements were physiological responses to epidural injections in both lidocaine and saline groups.
Area of Science:
- Neuroscience
- Histology
- Pharmacology
Background:
- Epidural anesthesia is common in veterinary medicine.
- Lidocaine is a widely used local anesthetic.
- Understanding the effects of epidural lidocaine on spinal cord neurons is crucial for patient safety.
Purpose of the Study:
- To investigate the morphofunctional and histoenzymological effects of epidural lidocaine on canine spinal cord neurons.
- To compare these effects with those of saline administration.
Main Methods:
- Mongrel dogs received epidural administration of isobaric 2% lidocaine solution or 0.9% sodium chloride (control).
- Morphofunctional and histoenzymological analyses of spinal cord neurons were performed.
Main Results:
- No pathological structural-metabolic changes were observed in nerve tissue following lidocaine treatment.
- Both lidocaine and saline groups exhibited similar morphofunctional rearrangements in spinal cord neurons.
- These changes were within physiological limits, indicating a functional response to epidural injections.
Conclusions:
- Epidural administration of isobaric 2% lidocaine solution does not induce pathological changes in canine spinal cord neurons.
- The observed neuronal changes represent physiological adaptations to the injection procedure itself, rather than specific toxicity from lidocaine.

01:24Local Anesthetics: Differential Sensitivity of Nerve Fibers
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...
01:29Local Anesthetics: Clinical Application as Epidural Anesthesia
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
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...
