Primary injury occurs immediately and directly from the initial effects of the insult (e.g. How to Perform a Neurologic Examination in Companion Animals In any patient with a suspected neurologic condition, a complete neurologic examination should follow the physical examination. The four most critical presentations or changes in neurological signs in the ICU patient are listed at the top of the algorithm with guidelines for immediate patient stabilization. Illustration: Kip Carter. 154, 2019, Fang H., Lafarge F.. We propose a 3D pyramid module to enrich pointwise features with multi-scale contextual information. If that is impossible then a multifocal neurological disorder is most likely present. If results are equivocal due to poor technique or an uncooperative patient, other tests can be performed to confirm findings.
