After graduation, she joined the neurology department at the Purdue University Veterinary Hospital, where she provides clinical case support and patient care and teaches the fundamentals of neurology and neurologic diseases to students in the veterinary nursing program at Purdue. A conscious response from the animal indicates pain (ie, vocalizing, trying to bite, turning the head, whining, dilating pupils, increased respiratory rate). A guide for localization of intracranial lesions by neurological and clinical signs is provided in Table 12.3. In an awake patient, the quality of consciousness should also be considered. It is important to note that intact reflex pathways in the limb do not correlate to intact perception of pain sensation. CheyneStokes respirations are cycles where respiration becomes increasingly deeper then increasingly shallower with possible apneic periods. Diencephalon localize the lesion(s) Source: Platt SR, Radaelli ST, McDonnell JJ. Supplementation to normal levelsNormalize with drug therapy or radioactive iodine 6 Normal cranial nerve function reduces the likelihood of a lesion in a specific region of the brainstem. Changes in mental status can indicate simply a minor systemic illness, or could indicate . Stimulation of sensory peripheral and cranial nerves projects impulses into the reticular formation within the medulla, pons, and midbrain, which then projects through the diencephalon to alert the cerebral cortex. Then test a 3-step command, such as "Take this piece of paper in your right hand. Withdrawal reflex (thoracic limb): Watch for flexion of all joints; the reduced reflex often is best seen in the shoulder joint. Semicomatose, responsive only to repeated noxious stimuli An updated approach calls for a more conservative dosage of 10 to 20 mL/kg over 15 to 20 minutes and reassessing the patient's perfusion parameters (heart rate, pulse quality, mucous membrane color, capillary refill time, extremity temperature and mentation).

Changes in levels of consciousness include stupor (laterally recumbent responsive only to noxious stimuli) or coma (unconscious, unresponsive to any stimuli) (Table 12.5). Observing intact perception of pain sensation in a limb requires the patient to display a conscious reaction to the stimulation, such as biting, whining, or looking toward the stimulation source.5 For example, a patient can have a normal withdrawal reflex in a limb but be unable to perceive painful stimulation applied to that same limb. Outcome was classified as survival or nonsurvival to hospital discharge. 660Lbs.

Asymmetrical neurological deficits suggest a more focal disorder, such as mass, infarct or hemorrhage. Aspiration pneumonia can be a devastating complication. Figure 8. Careful examination for evidence of trauma, systemic disease, pain, bleeding or bruising should be performed to detect systemic problems that can impact the nervous system. Discontinue, reverse drug if possibleWait for effects of drug to wear off 4 Loss of consciousness and changes in posture and pupils discussed below usually accompany abnormal respirations.
