Seven cadavers were injected in the mid-epigastrium (ME), while 8 were injected in\u00a0the left lower quadrant (LLQ). Each cadaver was scanned after each of the 3 injections by 2 trained and blinded EPs, resulting\u00a0in 45 scans per sonographer. Scans were performed using previously validated and standardized techniques. All scans were\u00a0recorded, time-stamped and labeled. For each scan the sonographers indicated \u201cyes\u201d or \u201cno\u201d to whether pneumoperitoneum\u00a0was detected. A chi square analysis was performed to determine the sensitivity and specificity of PoCUS utilized by each sonographer\u00a0of pneumoperitoneum based on the location and volume of air injected.Results: Free air (0.25-10 mL) injected into\u00a0the ME was successfully diagnosed in 36\/42 instances (86% sensitivity), but only detected in 10\/36 instances when injected\u00a0into the LLQ (28% sensitivity). Both EPs detected all air injections of \u22652 mL into the ME.Conclusion: Detection of free air\u00a0originating from the midepigastric region may become a future PoCUS indication for adequately trained EPs.<\/jats:p>","DOI":"10.11152\/mu-3238","type":"journal-article","created":{"date-parts":[[2021,9,11]],"date-time":"2021-09-11T07:41:22Z","timestamp":1631346082000},"page":"7","source":"Crossref","is-referenced-by-count":5,"title":["Feasibility of pneumoperitoneum diagnosis using point-of-care ultrasound: a pilot study using a fresh cadaver model"],"prefix":"10.11152","volume":"24","author":[{"given":"Meghan Kelly","family":"Herbst","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elizabeth M","family":"Carter","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shirley","family":"Wu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christoph Frank","family":"Dietrich","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1820-9430","authenticated-orcid":false,"given":"Beatrice","family":"Hoffmann","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"4840","published-online":{"date-parts":[[2022,2,16]]},"container-title":["Medical Ultrasonography"],"original-title":[],"link":[{"URL":"https:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/3238\/1918","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/3238\/1918","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,4,18]],"date-time":"2022-04-18T17:54:51Z","timestamp":1650304491000},"score":1,"resource":{"primary":{"URL":"https:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/view\/3238"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,2,16]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2022,2,16]]}},"URL":"https:\/\/doi.org\/10.11152\/mu-3238","relation":{},"ISSN":["2066-8643","1844-4172"],"issn-type":[{"value":"2066-8643","type":"electronic"},{"value":"1844-4172","type":"print"}],"subject":[],"published":{"date-parts":[[2022,2,16]]}}}
