Forty-six sevoflurane-midazolam anaesthetized piglets were included. External jugular vein catheterization was conducted through the ear vein using the Seldinger technique. Part 1 ( n\u2009=\u200927): optimal puncture site was based on the deltoid tuberosity as a landmark to reach the external jugular vein. The final position of the catheter was verified in 25 piglets using computer tomography. Catheterization time was recorded and patency of the catheter assessed by repeated blood sampling for up to 4\u2009h. Part 2 ( n\u2009=\u200919): ear vein catheterization was without taking into account any landmarks. Functionality for blood sampling was evaluated as described in part 1. Catheter advancement was possible in 25\/27 and 18\/19 piglets in parts 1 and 2, respectively. Median (range) time required for successful catheterization was 1.95 (1\u201310)\u2009min ( n\u2009=\u200938). The deltoid tuberosity was a good landmark to reach the external jugular vein. But blood sampling was also possible through catheters ending slightly cranial to the external jugular vein. Despite successful catheter advancement, blood sampling was not possible from one catheter in each part of the study (total: two piglets). One of these catheters presented luminal damage, while the other one presented as normal after being removed from the animal. Summarizing, central vein catheterization through the ear vein was feasible in 93.5% and repeated blood sampling was possible in 89.1% of the piglets ( n\u2009=\u200946).<\/jats:p>","DOI":"10.1177\/00236772231167224","type":"journal-article","created":{"date-parts":[[2023,4,20]],"date-time":"2023-04-20T02:01:53Z","timestamp":1681956113000},"page":"642-649","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Non-surgical external jugular vein catheterization using an ear vein access in piglets"],"prefix":"10.1177","volume":"57","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9346-3308","authenticated-orcid":false,"given":"S.K.","family":"Ringer","sequence":"first","affiliation":[{"name":"Section Anaesthesiology, Department of Clinical Diagnostics and Services, Vetsuisse Faculty University of Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Schmid","sequence":"additional","affiliation":[{"name":"Section Anaesthesiology, Department of Clinical Diagnostics and Services, Vetsuisse Faculty University of Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Weiss","sequence":"additional","affiliation":[{"name":"Department of Anaesthesia, University Children's Hospital Zurich, Switzerland"},{"name":"Children's Research Centre, University Children's Hospital of Zurich, University of Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Ohlerth","sequence":"additional","affiliation":[{"name":"Clinic of Diagnostic Imaging, Department of Clinical Diagnostics and Services, Vetsuisse Faculty University of Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N.","family":"Spielmann","sequence":"additional","affiliation":[{"name":"Department of Anaesthesia, University Children's Hospital Zurich, Switzerland"},{"name":"Children's Research Centre, University Children's Hospital of Zurich, University of Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N.G.","family":"Clausen","sequence":"additional","affiliation":[{"name":"Department of Anaesthesia, University Children's Hospital Zurich, Switzerland"},{"name":"Children's Research Centre, University Children's Hospital of Zurich, University of Zurich, Switzerland"},{"name":"Department of Anaesthesiology and Intensive Care, Odense University Hospital, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2023,4,19]]},"reference":[{"key":"bibr1-00236772231167224","doi-asserted-by":"publisher","DOI":"10.1258\/002367793781082412"},{"key":"bibr2-00236772231167224","doi-asserted-by":"publisher","DOI":"10.17221\/1992-VETMED"},{"key":"bibr3-00236772231167224","doi-asserted-by":"publisher","DOI":"10.1258\/002367799780578345"},{"key":"bibr4-00236772231167224","first-page":"18","volume":"41","author":"Fudge M","year":"2002","journal-title":"Contemp Top Lab Anim Sci"},{"key":"bibr5-00236772231167224","doi-asserted-by":"crossref","first-page":"e0241444","DOI":"10.1371\/journal.pone.0241444","volume":"28","author":"Furbeyre H","year":"2020","journal-title":"PLoS One"},{"key":"bibr6-00236772231167224","doi-asserted-by":"publisher","DOI":"10.1258\/la.2009.0080092"},{"key":"bibr7-00236772231167224","doi-asserted-by":"publisher","DOI":"10.1258\/002367799780578101"},{"key":"bibr8-00236772231167224","first-page":"1","volume":"33","author":"Niiyama M","year":"1984","journal-title":"Jpn J Vet Res"},{"key":"bibr9-00236772231167224","doi-asserted-by":"publisher","DOI":"10.1258\/002367792780740611"},{"key":"bibr10-00236772231167224","unstructured":"Ryden A, Teramura Y, Asif S, et\u00a0al.
