Changes in levels of consciousness include stupor (laterally recumbent responsive only to noxious stimuli) or coma (unconscious, unresponsive to any stimuli) (Table 12.5). It is easy to conflate performing neurologic evaluations with diagnosis and assume that neurologic examination is outside of a credentialed veterinary nurses scope of practice. If that is impossible then a multifocal neurological disorder is most likely present. It is therefore essential to monitor the neurological status of all ICU patients, giving particular attention to clinical signs of brain swelling, spinal cord compression, and systemic influences that may affect nervous tissue function. How to Perform a Neurologic Examination in Companion Animals Hansen BD. Alterations of mentation and consciousness may be graded from 1 to 18 using a modified Glasgow Coma Scale (Table 12.4).

Defining mental status can be difficult and nuanced; however, characterizing a patients level of consciousness as well as quality of consciousness can give the clearest picture of the patients mental state.4 Consciousness is produced by the appropriate function of both the forebrain and the ascending reticular activating system in the brainstem.4 Dysfunction of either of these areas, or both, results in the clinical observation of abnormal mental state.4. 1. Get it Feb 27 - Mar 2. The patient should return the paw to a normal position. Recumbent, constant extensor rigidity Triceps reflex evaluates C7 to T1 spinal nerves and, peripherally, the radial nerve (Figure 9). Plasma is not recommended unless clinical risk of bleeding is high or there is active hemorrhage It also initiates and controls voluntary movement and is critical for learning, behavior, and memory.3 The cerebellum controls force and range of movement, producing fluid muscle activity, and is closely associated with the vestibular system, providing input to control the bodys equilibrium and balance.3 The brainstem connects the spinal cord to the forebrain and relays information between the two. Edema of the nervous tissue occurs due to the release of inflammatory mediators, reactive oxygen species, and enzyme systems, each leading to cell death. Brainstem eflexes Menace responseVisual tracking of cotton ball/object Flex the paw so the dorsum of the paw is on the floor; do not let the patient put weight on the paw. Normal heart rate for dogs.

At this time, the patient is observed with little to no intervention from the evaluators. 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 In order of increasing severity, these categories are normal, obtunded, stuporous, and comatose.5 Characteristics of each are described in BOX 1. A stronger stimulus may be required in a tense patient with increased muscle tone. Prolonged seizures result in hypoxia, hypoglycemia, hyperthermia, and lactic acidosis and constitute a neurological emergency. Respiratory rate and effort, cardiac output, blood pressure, endocrine regulation, and basal organ functions depend upon the integrity of the brain and spinal cord. Motor to extraocular muscle (dorsal oblique) Figure 12.1 Prioritization and approach to severe neurological signs in the ICU patient.

Hemiwalking is similar to hopping, but 2 ipsilateral (same side) limbs remain on the ground. Evaluation of muscle mass and tone provides additional information, as low muscle tone or atrophy also reflects nerve or segmental spinal cord dysfunction.

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. When cardiac output is reduced, sympathetic nervous system activity may maintain blood pressure within normal limits but may decrease renal blood flow. Metabolic and homeostatic changes such as hypotension, hypoxia, hypoglycemia or fever contribute to secondary damage (Table 12.1). Hyperventilation can occur with severe midbrain disease, but must be differentiated from hyperventilation associated with acidosis or pain.
