Toxins primarily associated with tremors (may progress to seizures) Confirm the existence of a neurologic condition The MS2210R is a heavy-duty veterinary scale with medical-grade loadcells for excellent accuracy, available in 150kg or 300kg models. Function Whether the patient presents to the ICU with neurological signs or develops neurological signs later as a consequence of disease outside the nervous system, there is little room for error in diagnosis and administering treatments. 2001;15(6):5814. AAHA. Carbamates The functions of the cranial nerves (Table 12.6) are assessed to evaluate the health of the peripheral nerve and the area of the brainstem containing the nucleus of that nerve. } Severe cerebral or diencephalic (cranial brainstem) lesions can result in CheyneStokes respirations. Neurological derangement The normal time it takes for the capillaries to refill in the dog and cat is 1.5 seconds.

A conscious response from the animal indicates pain (ie, vocalizing, trying to bite, turning the head, whining, dilating pupils, increased respiratory rate). Seizures, coma, paraplegia, quadriplegia, and generalized tremors are four of the most devastating neurological problems that necessitate early recognition and immediate therapeutic intervention for ICU patients (Figure 12.1). veterinary mentation scale When cardiac output is reduced, sympathetic nervous system activity may maintain blood pressure within normal limits but may decrease renal blood flow.
