Although anesthetic techniques have evolved internally over many years to improve patient safety and outcomes, many of these methods remain undescribed in literature.<\/jats:p><\/jats:sec><jats:sec><jats:title>Technique<\/jats:title><jats:p>In this article, we describe the intraoperative negative pressure suction test. This simulates the negative pressure seen in awake and spontaneously breathing patients, including the higher pressures seen during coughing which induce airway collapse in patients with TBM. Also known as the Munoz maneuver in surgical literature, this test has been performed on over 300 patients since 2015.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>The negative pressure suction test allows for controlled intraoperative assessment of surgical airway repairs, replaces the need for risky intraoperative wake\u2010up tests, increases the chances of a successful surgical repair, and improves anesthetic management for emergence and extubation. We provide a guide on how to perform the test and videos demonstrating its efficacy in intraoperative airway evaluation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>As surgeries to repair TBM become more prevalent in other pediatric institutions, we believe that pediatric patients and anesthesia providers will benefit from the insights and methods described here.<\/jats:p><\/jats:sec>","DOI":"10.1111\/pan.14822","type":"journal-article","created":{"date-parts":[[2023,12,22]],"date-time":"2023-12-22T07:15:05Z","timestamp":1703229305000},"page":"289-292","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Negative pressure suction test: An intraoperative airway maneuver to assess effectiveness of surgical correction of tracheobronchomalacia"],"prefix":"10.1111","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-5983-1370","authenticated-orcid":false,"given":"Frederick H.","family":"Kuo","sequence":"first","affiliation":[{"name":"Department of Anesthesia Johns Hopkins All Children's Hospital  St Petersburg Florida USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard A.","family":"Elliott","sequence":"additional","affiliation":[{"name":"Department of Anesthesia Johns Hopkins All Children's Hospital  St Petersburg Florida USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Scott C.","family":"Watkins","sequence":"additional","affiliation":[{"name":"Department of Anesthesia Johns Hopkins All Children's Hospital  St Petersburg Florida USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hester F.","family":"Shieh","sequence":"additional","affiliation":[{"name":"Department of Surgery Johns Hopkins All Children's Hospital  St Petersburg Florida USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Charles J.","family":"Smithers","sequence":"additional","affiliation":[{"name":"Department of Surgery Johns Hopkins All Children's Hospital  St Petersburg Florida USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Russell W.","family":"Jennings","sequence":"additional","affiliation":[{"name":"Department of Surgery Johns Hopkins All Children's Hospital  St Petersburg Florida USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos","family":"Munoz\u2010San\u00a0Julian","sequence":"additional","affiliation":[{"name":"Department of Anesthesia Johns Hopkins All Children's Hospital  St Petersburg Florida USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,12,21]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.3389\/fped.2019.00512"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.21037\/tp-23-39"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.xjtc.2021.04.014"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.sempedsurg.2021.151062"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1159\/000485464"}],"container-title":["Pediatric Anesthesia"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/pan.14822","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,3,3]],"date-time":"2024-03-03T06:25:52Z","timestamp":1709447152000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/pan.14822"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,12,21]]},"references-count":5,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2024,4]]}},"alternative-id":["10.1111\/pan.14822"],"URL":"https:\/\/doi.org\/10.1111\/pan.14822","archive":["Portico"],"relation":{},"ISSN":["1155-5645","1460-9592"],"issn-type":[{"value":"1155-5645","type":"print"},{"value":"1460-9592","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,12,21]]},"assertion":[{"value":"2023-09-08","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-12-10","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-12-21","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
