After preanaesthetic medication with intramuscular midazolam (0.5 mg\/kg body mass), ketamine (10 mg\/kg) and butorphanol (0.5 mg\/kg) anaesthesia was induced in five piglets, with intravenous propofol (1 mg\/kg) followed by tracheal intubation and mechanical lung ventilation. Soft tissue surgery was performed in the jugular and inguinal regions during TIVA with propofol (8 mg\/kg\/h) and fentanyl (35 \u03bcg\/kg\/h). Anaesthesia was maintained for 300 min after surgery as the piglets were the control group of a project involving extracorporeal membrane oxygenation. Mean plasma cortisol concentration decreased significantly ( P &lt; 0.05) from 59 \u00b1 39.9 nmol\/L (mean \u00b1 1 SD) before surgery to 7.5 \u00b1 2.5 nmol\/L 300 min after end of surgical procedure. The mean SAA concentrations increased over the same period from 1.6 \u00b1 2.3 \u03bcg\/mL to 4.2 \u00b1 5.6 \u03bcg\/mL without statistical significance. The baseline (presurgery) mean arterial pressure (MAP) was 72 \u00b1 9 mmHg compared with 72 \u00b1 11 mmHg 300 min after end of surgery. Neither heart rate nor lactate concentrations changed significantly over the same time points: heart rate was 104 \u00b1 11 and 103 \u00b1 15 beats\/min whereas mean lactate concentrations were reduced from 1.14 \u00b1 0.45 mmol\/L to 0.90 \u00b1 0.22 mmol\/L. Haemodynamic stability, a decrease in serum cortisol and a non-statistically significant rise in mean SAA concentrations suggest that the anaesthetic described suppresses the stress response of piglets to surgery without adverse cardiovascular effects. Therefore, it may prove useful in cardiovascular research. <\/jats:p>","DOI":"10.1258\/la.2008.0080026","type":"journal-article","created":{"date-parts":[[2009,4,23]],"date-time":"2009-04-23T18:20:26Z","timestamp":1240510826000},"page":"243-248","source":"Crossref","is-referenced-by-count":21,"title":["Haemodynamic changes and stress responses of piglets to surgery during total intravenous anaesthesia with propofol and fentanyl"],"prefix":"10.1177","volume":"43","author":[{"given":"G","family":"Sch\u00f6ffmann","sequence":"first","affiliation":[{"name":"Clinic of Anaesthesiology and Perioperative Intensive Care, Clinical Department of Small Animals and Horses, University of Veterinary Medicine Vienna, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P","family":"Winter","sequence":"additional","affiliation":[{"name":"Clinic for Ruminants, Clinical Department for Farm Animals and Heard Health Management, University of Veterinary Medicine Vienna, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R","family":"Palme","sequence":"additional","affiliation":[{"name":"Department of Natural Sciences, Institute of Biochemistry, University of Veterinary Medicine Vienna, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A","family":"Pollak","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Division of Neonatology and Pediatric Intensive Care, Medical University of Vienna, Waehringer Guertel 18\u201320, A-1090 Vienna, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G","family":"Trittenwein","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Division of Neonatology and Pediatric Intensive Care, Medical University of Vienna, Waehringer Guertel 18\u201320, A-1090 Vienna, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J","family":"Golej","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Division of Neonatology and Pediatric Intensive Care, Medical University of Vienna, Waehringer Guertel 18\u201320, A-1090 Vienna, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2009,7,1]]},"reference":[{"key":"bibr-LA-08-026C1","first-page":"348","volume":"36","author":"Hughes HC","year":"1986","journal-title":"Lab Anim Sci"},{"key":"bibr-LA-08-026C2","doi-asserted-by":"publisher","DOI":"10.1097\/01.shk.0000075571.93053.2c"},{"key":"bibr-LA-08-026C3","first-page":"995","volume":"46","author":"Schnoor J","year":"2005","journal-title":"Can Vet J"},{"key":"bibr-LA-08-026C4","doi-asserted-by":"publisher","DOI":"10.1111\/j.1742-7843.2007.00099.x"},{"key":"bibr-LA-08-026C5","doi-asserted-by":"publisher","DOI":"10.1093\/bja\/aeg259"},{"key":"bibr-LA-08-026C6","doi-asserted-by":"publisher","DOI":"10.1046\/j.1467-2987.2001.00050.x"},{"key":"bibr-LA-08-026C7","doi-asserted-by":"publisher","DOI":"10.1093\/bja\/85.1.109"},{"key":"bibr-LA-08-026C8","first-page":"219","volume":"27","author":"Gerard H","year":"1996","journal-title":"Vet Res"},{"key":"bibr-LA-08-026C9","first-page":"163","volume":"51","author":"Jacobson M","year":"2001","journal-title":"Comp Med"},{"key":"bibr-LA-08-026C10","doi-asserted-by":"publisher","DOI":"10.1111\/j.1439-0442.2004.00617.x"},{"key":"bibr-LA-08-026C11","doi-asserted-by":"publisher","DOI":"10.1080\/01652176.1995.9694521"},{"key":"bibr-LA-08-026C12","doi-asserted-by":"publisher","DOI":"10.1016\/S0378-1135(03)00136-6"},{"key":"bibr-LA-08-026C13","doi-asserted-by":"publisher","DOI":"10.1016\/S0165-2427(99)00012-4"},{"key":"bibr-LA-08-026C14","doi-asserted-by":"publisher","DOI":"10.1292\/jvms.65.511"},{"key":"bibr-LA-08-026C15","unstructured":"National Institute of Health.
