Thirty normothermic anaesthetized ventilated adults (ASA 1 to 2, aged 18 to 80 years) were studied. Temperatures were recorded using a thermistor at six different locations (middle of drain tube and at 0 to 20 cm distal to the drain tube in 5 cm increments) and compared to nasopharyngeal (thermistor) and aural (infrared tympanic thermometer) reference core temperatures. The temperature probe was successfully inserted into the oesophagus in all patients at the first attempt. Oesophageal temperature increased with depth from 0 to 5 cm (35.2 v 35.9, P&lt;0.0001) and 5 to 10 cm (35.9 v 36.3, P&lt;0.01), but was unchanged from 10 to 15 cm (36.3 v 36.6) and 15 to 20 cm (36.6 v 36.7). Aural temperature was higher than nasopharyngeal temperature (36.8 v 36.0, P&lt;0.0001). Aural temperature was 0.89 to 1.59\u00b0C higher than the oesophagus at 0 to 5 cm and 0.21 to 0.30\u00b0C higher than the oesophagus at 15 to 20 cm. Nasopharyngeal temperature was 0.06 to 0.76\u00b0C higher than the oesophagus at 0 to 5 cm and 0.62 to 0.84\u00b0C lower than the oesophagus at 15 to 20 cm. The lowest temperature was in the mid-point of the drain tube (34.7). We conclude that oesophageal core temperature measurement is feasible and accurate using the ProSeal laryngeal mask airway. The optimal location for the temperature probe is at 15 to 20 cm.<\/jats:p>","DOI":"10.1177\/0310057x0303100307","type":"journal-article","created":{"date-parts":[[2019,1,22]],"date-time":"2019-01-22T21:15:11Z","timestamp":1548191711000},"page":"282-285","source":"Crossref","is-referenced-by-count":7,"title":["Feasibility, Accuracy and Optimal Location for Oesophageal Core Temperature Measurements Using the ProSeal Laryngeal Mask Airway Drain Tube"],"prefix":"10.1177","volume":"31","author":[{"given":"S.","family":"Mitchell","sequence":"first","affiliation":[{"name":"Department of Anaesthesia and Intensive Care, Cairns Base Hospital, Cairns, Queensland and Department of Anaesthesia and Intensive Care Medicine, Leopold-Franzens University, Innsbruck, Austria"},{"name":"Cairns Base Hospital, Cairns, Queensland."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Brimacombe","sequence":"additional","affiliation":[{"name":"Department of Anaesthesia and Intensive Care, Cairns Base Hospital, Cairns, Queensland and Department of Anaesthesia and Intensive Care Medicine, Leopold-Franzens University, Innsbruck, Austria"},{"name":"University of Queensland and James Cook University, Cairns, Queensland."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Keller","sequence":"additional","affiliation":[{"name":"Department of Anaesthesia and Intensive Care, Cairns Base Hospital, Cairns, Queensland and Department of Anaesthesia and Intensive Care Medicine, Leopold-Franzens University, Innsbruck, Austria"},{"name":"Leopold-Franzens University, Innsbruck, Austria."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2003,6,1]]},"reference":[{"key":"bibr1-0310057X0303100307","doi-asserted-by":"publisher","DOI":"10.1093\/bja\/84.5.650"},{"key":"bibr2-0310057X0303100307","doi-asserted-by":"publisher","DOI":"10.1097\/00000542-200007000-00019"},{"key":"bibr3-0310057X0303100307","doi-asserted-by":"publisher","DOI":"10.1097\/00000542-200107000-00049"},{"key":"bibr4-0310057X0303100307","doi-asserted-by":"publisher","DOI":"10.1097\/00000542-200009001-00306"},{"key":"bibr5-0310057X0303100307","doi-asserted-by":"publisher","DOI":"10.1046\/j.1471-6712.2002.00069.x"},{"key":"bibr6-0310057X0303100307","volume-title":"Henley-on-Thames:","author":"LMA ProSeal\u2122 Instruction Manual.","year":"2000"},{"key":"bibr7-0310057X0303100307","doi-asserted-by":"publisher","DOI":"10.1016\/S0750-7658(01)00507-X"},{"key":"bibr8-0310057X0303100307","doi-asserted-by":"publisher","DOI":"10.1016\/S0196-0644(05)82571-5"},{"key":"bibr9-0310057X0303100307","doi-asserted-by":"publisher","DOI":"10.1177\/096228029900800204"},{"key":"bibr10-0310057X0303100307","doi-asserted-by":"publisher","DOI":"10.1097\/00000539-200106000-00053"},{"key":"bibr11-0310057X0303100307","doi-asserted-by":"publisher","DOI":"10.1007\/BF01616917"},{"key":"bibr12-0310057X0303100307","doi-asserted-by":"publisher","DOI":"10.1097\/00000539-200111000-00065"},{"key":"bibr13-0310057X0303100307","first-page":"476","volume":"21","author":"Cowling J.","year":"1993","journal-title":"Anaesth Intensive Care"},{"key":"bibr14-0310057X0303100307","doi-asserted-by":"publisher","DOI":"10.1053\/apnr.2002.29528"}],"container-title":["Anaesthesia and Intensive Care"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0310057X0303100307","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0310057X0303100307","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T09:10:10Z","timestamp":1777367410000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/0310057X0303100307"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2003,6]]},"references-count":14,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2003,6]]}},"alternative-id":["10.1177\/0310057X0303100307"],"URL":"https:\/\/doi.org\/10.1177\/0310057x0303100307","relation":{},"ISSN":["0310-057X","1448-0271"],"issn-type":[{"value":"0310-057X","type":"print"},{"value":"1448-0271","type":"electronic"}],"subject":[],"published":{"date-parts":[[2003,6]]}}}
