He also presented with motor and sensory disturbances of the right upper extremity and was suspected of having a brachial plexus injury. After undergoing mechanical ventilation due to multiple traumas, he was extubated. However, he developed acute respiratory failure and required reintubation. Respiratory symptoms were not clear until just before reintubation. The diagnosis of right diaphragm paralysis was made using point-of-care ultrasound with no other findings that could cause respiratory failure. MRI led to the diagnosis of brachial plexus injury, which likely caused diaphragm paralysis. Point-of-care ultrasound provided a clear visualisation and rapid bedside diagnosis of diaphragm paralysis, which can be challenging to diagnose while ruling out other causes of respiratory failure.<\/jats:p>","DOI":"10.1136\/bcr-2021-246923","type":"journal-article","created":{"date-parts":[[2022,2,28]],"date-time":"2022-02-28T10:50:40Z","timestamp":1646045440000},"page":"e246923","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":6,"title":["Respiratory failure due to diaphragm paralysis after brachial plexus injury diagnosed by point-of-care ultrasound"],"prefix":"10.1136","volume":"15","author":[{"given":"Wataru","family":"Yajima","sequence":"first","affiliation":[{"name":"Department of Emergency Medicine, Jikei University School of Medicine, Minato-ku, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takuo","family":"Yoshida","sequence":"additional","affiliation":[{"name":"Department of Intensive Care Medicine, Tokyo Women's Medical University, Shinjuku-ku, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tatsuya","family":"Kondo","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, Jikei University School of Medicine, Minato-ku, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masahiko","family":"Uzura","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, Jikei University School of Medicine, Minato-ku, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2022,2,28]]},"reference":[{"key":"2025082708303555000_15.2.e246923.1","doi-asserted-by":"publisher","DOI":"10.1097\/00006123-199706000-00014"},{"key":"2025082708303555000_15.2.e246923.2","doi-asserted-by":"crossref","first-page":"22","DOI":"10.3390\/jfmk5020022","article-title":"Brachial plexus injuries in sport medicine: clinical evaluation, diagnostic approaches, treatment options, and rehabilitative interventions","volume":"5","author":"Belviso","year":"2020","journal-title":"J Funct Morphol Kinesiol"},{"key":"2025082708303555000_15.2.e246923.3","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMra1007236"},{"key":"2025082708303555000_15.2.e246923.4","doi-asserted-by":"publisher","DOI":"10.1016\/j.rmed.2004.04.016"},{"key":"2025082708303555000_15.2.e246923.5","doi-asserted-by":"publisher","DOI":"10.5152\/dir.2013.13248"},{"key":"2025082708303555000_15.2.e246923.6","doi-asserted-by":"crossref","DOI":"10.1016\/S0140-6736(20)32027-4","article-title":"C4 root compression leads to phrenic nerve palsy with shortness of breath, chest pain, and elevated hemidiaphragm","volume":"396","author":"Durand","year":"2020","journal-title":"Lancet"},{"key":"2025082708303555000_15.2.e246923.7","doi-asserted-by":"publisher","DOI":"10.1002\/mus.1160"},{"key":"2025082708303555000_15.2.e246923.8","doi-asserted-by":"publisher","DOI":"10.3171\/jns.2006.105.6.835"},{"key":"2025082708303555000_15.2.e246923.9","doi-asserted-by":"publisher","DOI":"10.1136\/emj.2008.059691"},{"key":"2025082708303555000_15.2.e246923.10","doi-asserted-by":"crossref","DOI":"10.36416\/1806-3756\/e20200064","article-title":"Diaphragmatic ultrasound: a review of its methodological aspects and clinical uses","volume":"46","author":"Santana","year":"2020","journal-title":"J Bras Pneumol"},{"key":"2025082708303555000_15.2.e246923.11","doi-asserted-by":"crossref","DOI":"10.1186\/s12890-021-01441-6","article-title":"Ultrasound and non-ultrasound imaging techniques in the assessment of diaphragmatic dysfunction","volume":"21","author":"Laghi","year":"2021","journal-title":"BMC Pulm Med"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2021-246923","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T15:30:43Z","timestamp":1756308643000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2021-246923"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,2]]},"references-count":11,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2022,2,28]]},"published-print":{"date-parts":[[2022,2]]}},"alternative-id":["10.1136\/bcr-2021-246923"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2021-246923","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,2]]}}}
