Preoperative hypovolemia is a key risk factor, and many parameters are available from ultrasound to detect hypovolemia, but the accuracy of PIH from ultrasound remains unclear. This systematic review and meta-analysis aimed to evaluate the commonly used measurements from ultrasound to predict PIH. We searched the PubMed, Cochrane Library, Embase, CNKI, and Web of Science databases from their inception to December 2023. Thirty-six studies were included for quantitative analysis. The pooled sensitivities for the inferior vena cava collapsibility index (IVC-CI), maximum inferior vena cava diameter (DIVCmax), minimum inferior vena cava diameter (DIVCmin), and carotid artery corrected flow time (FTc) were 0.73 (95% CI = 0.65, 0.79), 0.66 (95% CI = 0.54, 0.77), 0.74 (95% CI = 0.60, 0.85), and 0.81 (95% CI = 0.72, 0.88). The pooled specificities for the IVC-CI, DIVCmax, DIVCmin, and carotid artery FTc were 0.82 (95% CI = 0.75, 0.87), 0.75 (95% CI = 0.66, 0.82), 0.76 (95% CI = 0.65, 0.84), and 0.87 (95% CI = 0.77, 0.93). The AUC for the IVC-CI, DIVCmax, DIVCmin, and carotid artery FTc were 0.84 (95% CI = 0.81, 0.87), 0.77 (95% CI = 0.73, 0.81), 0.82 (95% CI = 0.78, 0.85), and 0.91 (95% CI = 0.88, 0.93). Our study demonstrated that ultrasound indices are reliable predictors for PIH. The carotid artery FTc is probably the optimal ultrasound measurement for identifying patients who will develop PIH in our study.<\/jats:p>","DOI":"10.3390\/jpm14050452","type":"journal-article","created":{"date-parts":[[2024,4,25]],"date-time":"2024-04-25T08:08:32Z","timestamp":1714032512000},"page":"452","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Preoperative Ultrasound for the Prediction of Postinduction Hypotension: A Systematic Review and Meta-Analysis"],"prefix":"10.3390","volume":"14","author":[{"given":"Chunyu","family":"Liu","sequence":"first","affiliation":[{"name":"Department of Anesthesiology, Chongqing University Cancer Hospital, Chongqing 400030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ran","family":"An","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Chongqing University Cancer Hospital, Chongqing 400030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9743-1039","authenticated-orcid":false,"given":"Hongliang","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Chongqing University Cancer Hospital, Chongqing 400030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1223","DOI":"10.1111\/anae.14416","article-title":"The Association of Hypotension During Non-Cardiac Surgery, before and after Skin Incision, with Postoperative Acute Kidney Injury: A Retrospective Cohort Analysis","volume":"73","author":"Maheshwari","year":"2018","journal-title":"Anaesthesia"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"461","DOI":"10.1097\/ALN.0000000000003063","article-title":"Preoperative Risk and the Association between Hypotension and Postoperative Acute Kidney Injury","volume":"132","author":"Mathis","year":"2020","journal-title":"Anesthesiology"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"563","DOI":"10.1016\/j.bja.2019.01.013","article-title":"Perioperative Quality Initiative Consensus Statement on Intraoperative Blood Pressure, Risk and Outcomes for Elective Surgery","volume":"122","author":"Sessler","year":"2019","journal-title":"Br.
