Therefore, we evaluated the role of ultrasound in pediatric patients to compare the correct size of an uncuffed (ETT) with the minimal transverse diameter of the subglottic airway (MTDSA) measured by ultrasound and with tube size predicted by different age\u2010related formulas.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Methods:\u2002<\/jats:bold>\n                    A total of 50 pediatric patients \u22645\u2003years were enrolled. As a standard, we defined the adequate ETT size with no audible leakage below a ventilation pressure of 15\u2003mbar and with an audible leakage above 25\u2003mbar. The maximum allowed difference between the prediction method result and the ETT that fit was defined as 0.3\u2003mm. Ultrasound was performed before the intubation procedure; the intubating anesthesiologists were blinded to the results of the ultrasound measurement. Agreement between the two age\u2010based formulas most commonly used at our department and MTDSA with the correct ETT size (standard) was analyzed using a Bland\u2013Altman plot. Correlation and regression analyses were performed and the numbers of correct intubation trials recorded.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:\u2002<\/jats:bold>\n                    The frequency of bias \u22640.3\u2003mm between each method and the correct ETT in the first attempt was &lt;50% and the mean number of reintubations 1.6\u2003\u00b1\u20031.3. In contrast to age\u2010related formulas, however, the ultrasonographically determined MTDSA was not significantly different from the correct ETT. MTDSA was highly associated with the outer diameter of the ETT (\n                    <jats:italic>r<\/jats:italic>\n                    \u2003=\u20030.869,\n                    <jats:italic>R<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    \u2003=\u20030.754).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusions:\u2002<\/jats:bold>\n                    Measuring MTDSA by ultrasound facilitates selection of the appropriate ETT in pediatric patients and may reduce the number of reintubations.\n                  <\/jats:p>","DOI":"10.1111\/j.1460-9592.2012.03889.x","type":"journal-article","created":{"date-parts":[[2012,5,21]],"date-time":"2012-05-21T09:09:42Z","timestamp":1337591382000},"page":"781-786","source":"Crossref","is-referenced-by-count":76,"title":["Role of ultrasound compared to age\u2010related formulas for uncuffed endotracheal intubation in a pediatric population"],"prefix":"10.1111","volume":"22","author":[{"given":"Christoph","family":"Schramm","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jana","family":"Knop","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katrin","family":"Jensen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Konstanze","family":"Plaschke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2012,5,21]]},"reference":[{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(83)80191-7"},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/PCC.0b013e3181dbeb28"},{"key":"e_1_2_8_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF03011411"},{"key":"e_1_2_8_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/ppul.1950060311"},{"key":"e_1_2_8_6_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF03018551"},{"key":"e_1_2_8_7_2","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2006-0206"},{"key":"e_1_2_8_8_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10049-010-1372-1"},{"key":"e_1_2_8_9_2","first-page":"672","article-title":"Pediatric formulas for the anesthesiologist","volume":"94","author":"Cole F","year":"1957","journal-title":"AMA J Dis Child"},{"key":"e_1_2_8_10_2","first-page":"269","volume-title":"Smith\u2019s Anesthesia for Infants and Children","author":"Motoyama EK","year":"1990"},{"key":"e_1_2_8_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0196-0644(05)82924-5"},{"key":"e_1_2_8_12_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.CCM.0000094228.90557.85"},{"key":"e_1_2_8_13_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1399-6576.2006.01003.x"},{"key":"e_1_2_8_14_2","doi-asserted-by":"publisher","DOI":"10.1213\/01.ane.0000260136.53694.fe"},{"key":"e_1_2_8_15_2","doi-asserted-by":"publisher","DOI":"10.2310\/7070.2002.21697"},{"key":"e_1_2_8_16_2","doi-asserted-by":"publisher","DOI":"10.1097\/ALN.0b013e3181ef6757"},{"key":"e_1_2_8_17_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2044.2011.06900.x"},{"key":"e_1_2_8_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(86)90837-8"},{"key":"e_1_2_8_19_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.brs.0000197203.76653.d0"}],"container-title":["Pediatric Anesthesia"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fj.1460-9592.2012.03889.x","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/j.1460-9592.2012.03889.x","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,30]],"date-time":"2023-10-30T16:20:37Z","timestamp":1698682837000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/j.1460-9592.2012.03889.x"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,5,21]]},"references-count":18,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2012,8]]}},"alternative-id":["10.1111\/j.1460-9592.2012.03889.x"],"URL":"https:\/\/doi.org\/10.1111\/j.1460-9592.2012.03889.x","archive":["Portico"],"relation":{},"ISSN":["1155-5645","1460-9592"],"issn-type":[{"value":"1155-5645","type":"print"},{"value":"1460-9592","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012,5,21]]}}}
