We hypothesized that compared with the use of volume-controlled ventilation (VCV), the use of the AutoFlow\u00ae mode would decrease PAWP and airway leak during laparoscopic gynecological surgery with LMA ProSeal.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>This single-center, randomized, controlled trial allocated 80 adult women undergoing elective laparoscopic gynecological surgery to one of two groups, namely, the AutoFlow group or the VCV group. Ventilation settings for both groups were 8\u2009ml\/kg of tidal volume and 5 cmH<jats:sub>2<\/jats:sub>O of positive end-expiratory pressure, and respiratory rate was adjusted to maintain end-tidal carbon dioxide at 35\u201340\u2009mmHg. Airway leak, PAWP, and other ventilatory parameters and vital signs were recorded at four timepoints (1, 1\u2009min after insertion of the gastric tube; 2, 2\u2009min after intravenous administration of rocuronium 0.6\u20130.8\u2009mg\/kg; 3, 1\u2009min after initiation of pneumoperitoneum; and 4, 1\u2009min after changing to the Trendelenburg position). The primary outcome was PAWP during pneumoperitoneum and in the Trendelenburg position, whereas the secondary outcomes included PAWP at other timepoints and airway leak development. We used the Mann\u2013Whitney U test for PAWP and Fisher\u2019s exact test for comparing airway leak among the groups.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Data from 40 patients in the AutoFlow group and 39 in the VCV group were used for analysis. PAWP at pneumoperitoneum pressure and in the Trendelenburg position was significantly lower in the AutoFlow group than in the VCV group [median (interquartile range), 16 (15\u201318) cmH<jats:sub>2<\/jats:sub>O vs. 18 (17\u201319) cmH<jats:sub>2<\/jats:sub>O; <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001]. Similarly, patients in the AutoFlow group showed lower PAWP at the other three timepoints measured. Airway leak occurred in four patients in the AutoFlow group and in two patients in the VCV group; however, this incidence was not significantly different (<jats:italic>P<\/jats:italic>\u2009=\u20090.68).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Even though AutoFlow ventilation decreased PAWP, it did not reduce the incidence of airway leak compared with VCV during laparoscopic gynecological surgery with the LMA ProSeal.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Trial registration<\/jats:title>\n                <jats:p>UMIN Clinical Trials Registry, identifier <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/upload.umin.ac.jp\/cgi-open-bin\/ctr_e\/ctr_view.cgi?recptno=R000026709\">UMIN000023173<\/jats:ext-link>.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s12871-021-01406-6","type":"journal-article","created":{"date-parts":[[2021,6,28]],"date-time":"2021-06-28T08:02:44Z","timestamp":1624867364000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["AutoFlow\u00ae versus volume-controlled ventilation for laparoscopic gynecological surgery using LMA\u00ae ProSeal\u2122: a randomized controlled trial"],"prefix":"10.1186","volume":"21","author":[{"given":"Toshiyuki","family":"Nakanishi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seishi","family":"Sakamoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manabu","family":"Yoshimura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takashi","family":"Toriumi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,6,28]]},"reference":[{"issue":"1","key":"1406_CR1","doi-asserted-by":"publisher","first-page":"71","DOI":"10.1007\/BF03020191","volume":"50","author":"JR Maltby","year":"2003","unstructured":"Maltby JR, Beriault MT, Watson NC, Liepert DJ, Fick GH.
