Correct placement is crucial. The aim of this study was to evaluate electrical impedance tomography (\n EIT<\/jats:styled-content>\n ) for guiding and confirmation of paediatric\n ETT<\/jats:styled-content>\n placement. In a retrospective analysis of stored\n EIT<\/jats:styled-content>\n data, distribution of ventilation between left and right lung was used to verify correct paediatric\n ETT<\/jats:styled-content>\n placement.\n <\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n \n Left and right lung ventilation was studied by\n EIT<\/jats:styled-content>\n in 18 paediatric patients (median age: 53 months) requiring anaesthesia and endotracheal intubation.\n EIT<\/jats:styled-content>\n was recorded before induction of anaesthesia, during mask ventilation, during\n ETT<\/jats:styled-content>\n placement (including deliberate mainstem intubation), and after\n ETT<\/jats:styled-content>\n repositioning according to the formula:\n ETT<\/jats:styled-content>\n intubation depth (cm)\u2009=\u20093\u00d7\n ETT<\/jats:styled-content>\n internal diameter (mm) or the mainstem intubation method (withdrawing the\n ETT<\/jats:styled-content>\n 2\u2009cm). Final\n ETT<\/jats:styled-content>\n position was confirmed by fluoroscopy.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Following deliberate mainstem intubation, distribution of ventilation to the right lung was unequivocally demonstrated by\n EIT<\/jats:styled-content>\n . Homogeneous distribution of ventilation between left and right lung monitored with\n EIT<\/jats:styled-content>\n correlated in each patient with correct endotracheal\n ETT<\/jats:styled-content>\n placement. The distribution of left and right lung ventilation differed significantly (\n P<\/jats:italic>\n \u2009<\u20090.05) between the initial two\u2010lung ventilation and subsequent right one\u2010lung ventilation, and between right one\u2010lung and subsequent two\u2010lung ventilation according to auscultation and the final\n ETT<\/jats:styled-content>\n position, respectively. In one patient,\n ETT<\/jats:styled-content>\n was misplaced within the oesophagus which was also obvious from the\n EIT<\/jats:styled-content>\n record.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n \n This study demonstrates that\n EIT<\/jats:styled-content>\n enables non\u2010invasive recognition of correct\n ETT<\/jats:styled-content>\n placement. Homogeneous right\u2010left\u2010lung ventilation is an indicator for correct\n ETT<\/jats:styled-content>\n placement.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/aas.12143","type":"journal-article","created":{"date-parts":[[2013,6,10]],"date-time":"2013-06-10T23:22:23Z","timestamp":1370906543000},"page":"881-887","source":"Crossref","is-referenced-by-count":23,"title":["Electrical impedance tomography for verification of correct endotracheal tube placement in paediatric patients: a feasibility study"],"prefix":"10.1111","volume":"57","author":[{"given":"D.","family":"STEINMANN","sequence":"first","affiliation":[{"name":"Department of Occupational Medicine University Medical Center Freiburg Freiburg Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"ENGEHAUSEN","sequence":"additional","affiliation":[{"name":"Department of Anaesthesia and Critical Care Medicine Ortenau Clinical Center Offenburg Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B.","family":"STILLER","sequence":"additional","affiliation":[{"name":"Department of Congenital Heart Disease University Heart Center Freiburg Freiburg Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"GUTTMANN","sequence":"additional","affiliation":[{"name":"Department of Anaesthesia and Critical Care Medicine University Medical Center Freiburg Freiburg Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2013,6,10]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/B978-141603134-5.50016-0"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1460-9592.2003.01103.x"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1213\/01.ANE.0000118104.23660.F3"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1460-9592.2005.01577.x"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.PCC.0000165802.32383.9E"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF03016560"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1213\/01.ane.0000278149.66027.0b"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1097\/ALN.0b013e3181730288"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF03017744"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003246-198809000-00013"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000539-199602000-00006"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003246-200101000-00035"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.CCM.0000134354.20449.B2"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2008-2828"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1213\/ane.0b013e31819240f5"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1111\/pan.12010"},{"key":"e_1_2_6_18_1","doi-asserted-by":"publisher","DOI":"10.1007\/s001340101021"},{"key":"e_1_2_6_19_1","doi-asserted-by":"publisher","DOI":"10.1097\/MCC.0b013e3283463c9c"},{"key":"e_1_2_6_20_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00134-009-1589-y"},{"key":"e_1_2_6_21_1","doi-asserted-by":"publisher","DOI":"10.1093\/bja\/aen166"},{"key":"e_1_2_6_22_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1460-9592.2011.03547.x"},{"key":"e_1_2_6_23_1","doi-asserted-by":"publisher","DOI":"10.1002\/ppul.22580"},{"key":"e_1_2_6_24_1","doi-asserted-by":"publisher","DOI":"10.1093\/bja\/88.2.283"}],"container-title":["Acta Anaesthesiologica Scandinavica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Faas.12143","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/aas.12143","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,5]],"date-time":"2023-10-05T09:01:50Z","timestamp":1696496510000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/aas.12143"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,6,10]]},"references-count":23,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2013,8]]}},"alternative-id":["10.1111\/aas.12143"],"URL":"https:\/\/doi.org\/10.1111\/aas.12143","archive":["Portico"],"relation":{},"ISSN":["0001-5172","1399-6576"],"issn-type":[{"value":"0001-5172","type":"print"},{"value":"1399-6576","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,6,10]]}}}
