This meta-analysis (Prospero registration number: CRD42024566321) aimed to evaluate the predictive efficacy of the perfusion index (PI) for PIH in patients undergoing general anesthesia. A comprehensive literature search was performed using multiple electronic databases (Google Scholar, EMBASE, Cochrane Library, and MEDLINE). Studies involving adult patients undergoing general anesthesia, with the PI measured before anesthesia induction and reporting PIH incidence, were included. The primary outcome was the diagnostic accuracy of the PI in predicting the probability of PIH. The secondary outcome was the pooled PIH incidence. Eight studies with 678 patients were included. The pooled incidence of PIH was 44.8% (95% confidence interval [CI]: 29.9%\u201360.8%). The combined sensitivity and specificity of the PI for predicting PIH were 0.84 (95% CI: 0.65\u20130.94) and 0.82 (95% CI: 0.70\u20130.90), respectively. The summary receiver operating characteristic (sROC) analysis revealed an area under curve of 0.89 (95% CI: 0.86\u20130.92). The Deek\u2019s funnel plot asymmetry test indicated no significant publication bias. The PI demonstrates high predictive efficacy for PIH in patients undergoing general anesthesia, indicating that it can be a valuable tool for identifying those at risk of PIH.<\/jats:p>","DOI":"10.3390\/diagnostics14161769","type":"journal-article","created":{"date-parts":[[2024,8,14]],"date-time":"2024-08-14T09:20:51Z","timestamp":1723627251000},"page":"1769","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["The Use of the Perfusion Index to Predict Post-Induction Hypotension in Patients Undergoing General Anesthesia: A Systematic Review and Meta-Analysis"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4507-8085","authenticated-orcid":false,"given":"Kuo-Chuan","family":"Hung","sequence":"first","affiliation":[{"name":"Department of Anesthesiology, Chi Mei Medical Center, Tainan 71004, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9109-2331","authenticated-orcid":false,"given":"Shu-Wei","family":"Liao","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Chi Mei Medical Center, Tainan 71004, Taiwan"},{"name":"Center of General Education, Chia Nan University of Pharmacy and Science, Tainan 71710, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chia-Li","family":"Kao","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, E-Da Hospital, I-Shou University, Kaohsiung 82445, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0884-9098","authenticated-orcid":false,"given":"Yen-Ta","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Surgery, National Cheng Kung University Hospital, College of Medicine, National Cheng Kung University, Tainan 70403, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3290-1909","authenticated-orcid":false,"given":"Jheng-Yan","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Nutrition, Chi Mei Medical Center, Tainan 71004, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6064-2660","authenticated-orcid":false,"given":"Yao-Tsung","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Chi Mei Medical Center, Tainan 71004, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chien-Ming","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Chi Mei Medical Center, Tainan 71004, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chien-Hung","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Chi Mei Medical Center, Tainan 71004, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-7122-6901","authenticated-orcid":false,"given":"I-Wen","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Chi Mei Medical Center, Liouying, Tainan 73657, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Weinberg, L., Li, S.Y., Louis, M., Karp, J., Poci, N., Carp, B.S., Miles, L.F., Tully, P., Hahn, R., and Karalapillai, D.
