Bilateral application of cold stimulus to the individual divisions of the trigeminal nerve revealed the ophthalmic division to be the most sensitive pathway for this reflex. The cold face test was standardized in 50 normal individuals and further validated in 10 patients by comparison with the simulated diving reflex, the Valsalva maneuver, and administration of atropine. Patients with diabetes mellitus, brainstem stroke, multiple sclerosis, or Shy\u2010Drager syndrome developed less than normal bradycardia or minimal tachycardia in response to the cold facial stimulus. The cold face test is a novel, simple, safe, and economical test of the integrity of trigeminal\u2010brainstem\u2010vagal reflex pathways, can be utilized practically to assess vagal and brainstem dysfunctions, and has the special advantage of being applicable even in an uncooperative or comatose patient.<\/jats:p>","DOI":"10.1002\/ana.410070209","type":"journal-article","created":{"date-parts":[[2005,1,1]],"date-time":"2005-01-01T16:57:46Z","timestamp":1104598666000},"page":"144-149","source":"Crossref","is-referenced-by-count":104,"title":["Cold face test in the assessment of trigeminal\u2010brainstem\u2010 vagal function in humans"],"prefix":"10.1002","volume":"7","author":[{"given":"Ramesh K.","family":"Khurana","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sadakiyo","family":"Watabiki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
