Pain on manipulation of the neck or back can provide an initial localization of a spinal cord lesion. Cranial nerves Metabolic and homeostatic changes such as hypotension, hypoxia, hypoglycemia or fever contribute to secondary damage (Table 12.1). // If there's another sharing window open, close it. The MGCS is useful for assigning an initial score to the patient . An apneustic breathing pattern is characterized by deep gasping inspirations held for 3090 seconds then expelled. Decreased acetylcholine release and neuromuscular blockade, Correct any potassium or calcium abnormalities as well as magnesium, Signs usually secondary to calcium sequestration leading to hypocalcemia, Patients with severe hypertension should have a stepwise decrease in pressure while hospitalized to avoid signs of hypotension, Deficiency in carbohydrate metabolism leading to energy depletion and neuronal necrosis, Seen with diets mainly of raw fish or diets heated to excessive temperatures, Not completely understood possibly depletion in energy metabolism and altered cerebral blood flow, Decreased metabolic demand and altered blood flow, Warming should be performed slowly with careful attention to blood pressure, Hemorrhage directly into or around nervous tissue leading to dysfunction and potential increased intracranial pressure, Monitor coagulation factor parameters and platelet numbers, Plasma is not recommended unless clinical risk of bleeding is high or there is active hemorrhage, Decreased cell membrane threshold potential, Always measure ionized levels as other factors can affect total calcium levels, Do not change serum sodium level faster than 0.5mEq/L/h unless the disease is acute to avoid worsened neurological insult, Discontinue or change route of administration, Discontinue, reduce dose, naloxone, change drug, Seizures, behavior change, dementia, delirium, depression, stupor or coma with normal or miotic pupils; head pressing; pacing; circling; loss of smell (CN I); blind with dilated pupils (CN II) or normal pupils; CheyneStokes breathing pattern, Acute lesions may have transient contralateral hemiparesis or quadriparesis; spinal reflexes normal or exaggerated, Stupor, coma, dilated (CN III) or midrange fixed pupils; ventrolateral strabismus (CN III); absent pupil light response (CN III); pupil rotation (CN IV), Quardriparesis with bilateral lesion; decerebrate rigidity with severe lesion; spinal reflexes normal or exaggerated in all four limbs, Depression, stupor, coma; miotic pupils with normal mentation; atrophy of temporal and masseter muscles or decreased facial sensation or hyperesthesia of face (CN V), Ipsilateral hemiparesis; spinal reflexes normal or exaggerated in all four limbs, Depressed or normal mentation; stupor or coma; medial strabismus (CN VI); reduced blink, lip and ear reflex (CN VII); nystagmus and disequilibrium (CN VIII), Depressed or normal mentation; stupor or coma; hyperventilation; apneustic breathing; heart rate and blood pressure alterations; dysphagia (CN IX or X); megaesophagus (CN X); laryngeal paresis (CN X); tongue atrophy or paralysis (CN XII), Intention tremors and ataxia of the head; head tilt away from lesion; nystagmus; loss of menace response; ipsilateral or bilateral dysmetria; normal limb strength, Normal reflexes all four limbs unless opisthotonus or decerebellate rigidity (conscious animal), Hemiparesis, tetraparesis, or decerebrate activity, Recumbent, intermittent extensor rigidity, Recumbent, constant extensor rigidity with opisthotonus, Recumbent, hypotonia of muscles, depressed or absent spinal reflexes, Normal pupillary reflexes and oculocephalic reflexes, Slow pupillary reflexes and normal to reduced oculocephalic reflexes, Bilateral unresponsive miosis and normal to reduced oculocephalic reflexes, Pinpoint pupils with reduced to absent oculocephalic reflexes, Unilateral, unresponsive mydriasis and reduced to absent oculocephalic reflexes, Bilateral, unresponsive mydriasis and reduced to absent oculocephalic reflexes, Occasional periods of alertness and responsive to environment, Depression or delirium, responsive, but response may be inappropriate, Semicomatose, responsive to visual stimuli, Semicomatose, responsive to auditory stimuli, Semicomatose, responsive only to repeated noxious stimuli, Comatose, unresponsive to repeated noxious stimuli, Exhibits a response typical of the normal temperament of the patient, Response is not typical of the normal temperament of the patient or is different from what is a normal expected response, Irrational or uncontrollable emotional response, Decreased conscious response to external nonnoxious stimuli subjectively is graded as mild, moderate or severe, Conscious response only with the application of a noxious stimulus, Lack of any conscious response to any external stimuli limited to a brief period of time (seconds or minutes), Prolonged lack of any conscious response to any external stimuli spinal and cranial nerve reflexes may or may not be present depending on the location of the lesion, Not usually tested. The pupillary light reflex evaluates the function of which nerves? 4 Changes in the breathing pattern may occur with disease of the cerebrum or one of the four parts of the brainstem (diencephalon, midbrain, pons, and medulla). As the control center of the body, the nervous system requires a consistent amount of oxygen and glucose to preserve lifesustaining metabolic functions.

Pain behaviors and pain assessment scales. Measures should be taken to reduce the risk of increasing intracranial pressure, such as positioning the patient with the head elevated, avoiding jugular compression, and alleviating pain and/or anxiety to keep the patient calm.6 Careful monitoring of the patients heart rate, blood pressure, and respiratory pattern can identify hypertension and bradycardia, components of the Cushing reflex. Flex the paw so the dorsum of the paw is on the floor; do not let the patient put weight on the paw.

Confusion, disorientation, and inappropriate reaction to stimulation may indicate forebrain dysfunction. Although these techniques all evaluate the patients proprioception, the choice of which to use is based on the patients temperament or even species. Orthopedic examination is performed to detect bone, tendon, joint, or muscular disorders that can influence the response to neurological testing or contribute to further neurological injury.

Dull mentationSeizuresComaDull mentationSeizuresComa An attempt should be made to explain all neurological deficits by a single lesion. This is best described with quantifying terminology indicating the number of limbs affected. Disease affecting this area of the spinal cord can also affect urinary and fecal continence.
Veterinary Scale, 440LB Heavy Duty Digital Livestock Platform Scale Table 12.6 Cranial nerve localization and evaluation. High cervical lesions can result in respiratory paresis or paralysis due to loss of intercostal and diaphragm motor function from compression, edema or hemorrhage and immediate ventilatory assistance may be required. Hemiwalking: Lift the limbs on the same side from the ground and push the patient toward the other side, which forces the animal to hop with the limbs on the ground. The following key words should be used to describe gait: Other abnormalities that provide a more precise description of the quality and degree of the paresis include: Paresis describes reduced voluntary motor function, while weakness describes a loss of muscle strength. Vet Rec 2001; 148:525-531.

Note: Movements elicited when touching the patient may be reflex movements rather than actual voluntary movement. CoagulationHypocoagulationHypercoagulation Like the patient in the first example, this patient is recumbent and will need similar interventions to prevent decubital ulceration, urine and fecal scalding, and joint contracture.
