Asystole occurred after mild stimulation of the supraorbital nerve during dissection along the superior orbital rim. Anticholinergics were administered and lidocaine-soaked gauze was applied to the exposed wound. The patient was an athlete and had pre-existing sinus bradycardia. We hypothesise that the severe reflex response was associated with his underlying increased vagal tone. When performing surgery in patients with increased vagal tone, preventative measures to diminish the trigeminocardiac reflex are recommended. Further studies are needed.<\/jats:p>","DOI":"10.1136\/bcr-2020-235419","type":"journal-article","created":{"date-parts":[[2020,8,25]],"date-time":"2020-08-25T03:20:49Z","timestamp":1598325649000},"page":"e235419","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Asystole due to stimulation of the supraorbital nerve: abrupt and potentially fatal presentation of the trigeminocardiac reflex"],"prefix":"10.1136","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6336-7622","authenticated-orcid":false,"given":"Hyunjee","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Anesthesiology and Pain Medicine, School of Medicine, Kyungpook National University, Daegu, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dong Gun","family":"Lim","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology and Pain Medicine, School of Medicine, Kyungpook National University, Daegu, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeong Eon","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology and Pain Medicine, School of Medicine, Kyungpook National University, Daegu, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2020,8,24]]},"reference":[{"key":"2025082803132068000_13.8.e235419.1","doi-asserted-by":"crossref","first-page":"136","DOI":"10.1097\/ANA.0000000000000065","article-title":"Trigeminocardiac reflex: the current clinical and physiological knowledge","volume":"27","author":"Chowdhury","year":"2015","journal-title":"J Neurosurg Anesthesiol"},{"key":"2025082803132068000_13.8.e235419.2","doi-asserted-by":"publisher","DOI":"10.1097\/ANA.0b013e3181a2bf22"},{"key":"2025082803132068000_13.8.e235419.3","doi-asserted-by":"crossref","DOI":"10.3389\/fneur.2017.00533","article-title":"Definition and diagnosis of the Trigeminocardiac reflex: a Grounded theory approach for an update","volume":"8","author":"Meuwly","year":"2017","journal-title":"Front Neurol"},{"key":"2025082803132068000_13.8.e235419.4","doi-asserted-by":"crossref","DOI":"10.1097\/MD.0000000000009033","article-title":"The clinical surrogate definition of the trigeminocardiac reflex: development of an optimized model according to a PRISMA-compliant systematic review","volume":"96","author":"Meuwly","year":"2017","journal-title":"Medicine"},{"key":"2025082803132068000_13.8.e235419.5","doi-asserted-by":"publisher","DOI":"10.1097\/00055735-200310000-00002"},{"key":"2025082803132068000_13.8.e235419.6","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199808063390602"},{"key":"2025082803132068000_13.8.e235419.7","doi-asserted-by":"crossref","first-page":"885","DOI":"10.1016\/j.jpeds.2013.03.054","article-title":"Long-Term outcomes of pediatric sinus bradycardia","volume":"163","author":"Chiu","year":"2013","journal-title":"J Pediatr"},{"key":"2025082803132068000_13.8.e235419.8","doi-asserted-by":"crossref","unstructured":"Goldberger AL , Goldberger ZD , Shvilkin A .
