However, the effect of the BURP maneuver is unclear when using the OptiscopeTM. Therefore, we retrospectively investigated the effect of the BURP maneuver on intubation using the OptiscopeTM.Methods: Sixty-eight patients intubated with the OptiscopeTM were enrolled. We used the BURP maneuver in Group A (n = 33) and the conventional maneuver (which does not use the BURP maneuver) in Group B (n = 35). BURP application status was a binary variable representing whether the BURP maneuver was used during the intubation. A multiple linear regression analysis was performed to assess the effects of the BURP application status on intubation time controlling for body mass index, preoperative dental injury status, obstructive sleep apnea history, thyromental distance, sternomental distance (SMD), interincisor distance, history of neck rotation restriction, and Mallampati classification.Results: There was no difference in the intubation time between the two groups. According to the regression model (R2 = 0.308, P = 0.007), the BURP maneuver (Group A) decreased the intubation time by 6.089 seconds (95% confidence interval 1.303\u201310.875, P = 0.014) compared to Group B.Conclusion: The BURP maneuver reduced intubation time when using the OptiscopeTM.<\/jats:p>","DOI":"10.17085\/apm.21026","type":"journal-article","created":{"date-parts":[[2021,10,22]],"date-time":"2021-10-22T04:29:30Z","timestamp":1634876970000},"page":"391-397","update-policy":"https:\/\/doi.org\/10.17085\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["The effects of backward, upward, rightward pressure maneuver for intubation using the OptiscopeTM: a retrospective study"],"prefix":"10.17085","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9476-5594","authenticated-orcid":true,"given":"Sei-hoon","family":"Oh","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1868-9454","authenticated-orcid":true,"given":"Sang-kwon","family":"Heo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5105-8304","authenticated-orcid":true,"given":"Seung-Uk","family":"Cheon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5544-3445","authenticated-orcid":true,"given":"Seung-Ah","family":"Ryu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2573","reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.4097\/kjae.2012.63.2.130"},{"key":"ref2","first-page":"1666","volume-title":"Cervical spine motion during tracheal intubation using an Optiscope versus the McGrath videolaryngoscope in patients with simulated cervical immobilization: a prospective randomized crossover study","author":"Nam","year":"2019"},{"key":"ref3","first-page":"870","volume-title":"McGrath MAC videolaryngoscope versus Optiscope video stylet for tracheal intubation in patients with manual inline cervical stabilization: a randomized trial","author":"Yoon","year":"2020"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1186\/s12871-020-00966-3"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.4103\/ija.ija_501_16"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.17085\/apm.2017.12.3.271"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1007\/bf03037041"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1097\/00000539-199702000-00033"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1177\/0300060520925325"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1111\/anae.13606"},{"key":"ref11","first-page":"353","volume-title":"A comparison between the GlideScope video laryngoscope and direct laryngoscope in paediatric patients with difficult airways -
