This study aimed to analyze the incidence of SHV in spontaneous cerebellar hemorrhage patients and its risk factors as well as its association with the outcome. Methods: We retrospectively reviewed the medical records of all spontaneous cerebellar hemorrhage patients who underwent surgical treatment at Tongji Hospital from July 2018 to December 2020. Arterial blood gas (ABG) test results and clinical characteristics, including demographics, comorbidities, imaging features, laboratory tests, and therapy choices, were collected. The Glasgow Outcome Scale was used to assess the outcome at two weeks and six months after admission. Results: A total of 147 patients were included, and of these patients 44.9% had spontaneous hyperventilation. Hypertension (OR, 3.175; CI, 1.332\u20137.569), usage of sedation drugs (OR, 3.693; CI, 1.0563\u20138.724), and hypernatremia (OR, 2.803; CI, 1.070\u20137.340) seemed to positively correlate to SHV occurrence. Hematoma removal had an inverse association with SHV (OR, 0.176; CI, 0.068\u20130.460). Patients with poor and good outcomes had significant differences in pH, PaCO2, and HCO3\u2212 values, and the severity of SHV was associated with the PaCO2 level. Conclusions: Spontaneous hyperventilation is common in patients with spontaneous cerebellar hemorrhage, and its severity is associated with the outcome.<\/jats:p>","DOI":"10.3390\/jcm11195564","type":"journal-article","created":{"date-parts":[[2022,9,22]],"date-time":"2022-09-22T21:10:05Z","timestamp":1663881005000},"page":"5564","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Spontaneous Hyperventilation Is Common in Patients with Spontaneous Cerebellar Hemorrhage, and Its Severity Is Associated with Outcome"],"prefix":"10.3390","volume":"11","author":[{"given":"Zhuangzhuang","family":"Miao","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science & Technology, Wuhan 430030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huajian","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Wuhan Fourth Hospital, Puai Hospital, Wuhan 430030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhi","family":"Cai","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science & Technology, Wuhan 430030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7484-6605","authenticated-orcid":false,"given":"Jin","family":"Lei","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science & Technology, Wuhan 430030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xueyan","family":"Wan","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science & Technology, Wuhan 430030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science & Technology, Wuhan 430030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junwen","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science & Technology, Wuhan 430030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7275-7315","authenticated-orcid":false,"given":"Kai","family":"Zhao","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science & Technology, Wuhan 430030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongquan","family":"Niu","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science & Technology, Wuhan 430030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ting","family":"Lei","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science & Technology, Wuhan 430030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"229","DOI":"10.1016\/0163-7258(93)90045-F","article-title":"The effect of carbon dioxide on cerebral arteries","volume":"59","author":"Madden","year":"1993","journal-title":"Pharmacol.
