Closed-loop vasopressor (CLV) systems automate titration to optimise blood pressure control, but their clinical effectiveness remains uncertain. We performed a systematic review and meta-analysis comparing CLV with manual titration. This PRISMA 2020\u2013compliant review was prospectively registered in PROSPERO (CRD420250655697). MEDLINE, Embase, Scopus, Web of Science, CENTRAL, and the Cochrane Library were searched (January 2000\u2013June 2025). Randomised controlled trials enrolling adults receiving vasopressors in perioperative or intensive care settings were included. Primary outcomes were time within the MAP target range and time spent in hypotension or hypertension. Risk of bias was assessed using RoB 2.0 and certainty of evidence using GRADE. Random- or fixed-effects models were selected according to heterogeneity. Six randomized controlled trials (215 patients) were included in the systematic review, whereas five perioperative trials contributed to the meta-analysis of haemodynamic control outcomes, and one ICU-based study was summarized narratively because it did not report comparable MAP control endpoints. CLV increased time within the MAP target range (mean difference [MD] 33.94%, 95% CI 20.41\u201347.46; I\n                    <jats:sup>2<\/jats:sup>\n                    \u2009=\u200977%) and reduced time in hypotension (MD\u2009\u2212\u200918.24%, 95% CI\u2009\u2212\u200928.95 to\u2009\u2212\u20097.53; I\n                    <jats:sup>2<\/jats:sup>\n                    \u2009=\u200973%). There was no significant difference in time in hypertension, cumulative norepinephrine dose, or major\/minor adverse events. ICU length of stay was not pooled because of clinical and methodological heterogeneity. Certainty of evidence ranged from low to high (moderate for haemodynamic control outcomes). CLV systems improved haemodynamic control, primarily in perioperative settings,\u00a0but heterogeneity and small samples limit confidence in effect size and generalisability.\u00a0Evidence in critically ill populations remains limited, and larger trials are needed to determine whether improvements in these physiological surrogate endpoints translate into meaningful patient-centred outcomes.\n                  <\/jats:p>","DOI":"10.1007\/s10877-026-01463-7","type":"journal-article","created":{"date-parts":[[2026,7,22]],"date-time":"2026-07-22T11:39:01Z","timestamp":1784720341000},"page":"1065-1076","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Closed-loop vasopressor systems for hemodynamic control in perioperative and critical care settings: a systematic review and meta-analysis"],"prefix":"10.1007","volume":"40","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4320-3150","authenticated-orcid":false,"given":"Jorge Iv\u00e1n","family":"Alvarado-S\u00e1nchez","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diana Mar\u00eda","family":"Abril-Calder\u00f3n","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isabella","family":"S\u00e1nchez-Quimbayo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucas","family":"O\u00f1oro-Pati\u00f1o","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7064-1765","authenticated-orcid":false,"given":"Camilo","family":"Vega-Useche","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-1853-9406","authenticated-orcid":false,"given":"Juan Sebasti\u00e1n","family":"Reyes-Gonzales","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0190-9959","authenticated-orcid":false,"given":"Fredy Leonardo","family":"Carre\u00f1o-Hernandez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,7,22]]},"reference":[{"key":"1463_CR1","doi-asserted-by":"publisher","first-page":"636","DOI":"10.1213\/ANE.0000000000004517","volume":"130","author":"K Maheshwari","year":"2020","unstructured":"Maheshwari K, Ahuja S, Khanna AK, Mao G, Perez-Protto S, Farag E, et al.
