We compared the effect of remimazolam anesthesia with that of propofol-induced and desflurane-maintained anesthesia on intraoperative hemodynamic stability and the need for vasoactive agents in patients undergoing cerebrovascular bypass surgery.Methods: Sixty-five patients were randomized into remimazolam (n = 31, remimazolam-based intravenous anesthesia) and control groups (n = 34, propofol-induced and desflurane-maintained anesthesia). The primary outcome was the occurrence of intraoperative hypotension. The secondary outcomes included hypotension duration, lowest mean BP (MBP), generalized average real variability (ARV) of MBP, and consumption of phenylephrine, norepinephrine, or remifentanil. Results: Occurrence rate and duration of hypotension were significantly lower in the remimazolam group (38.7% vs. 73.5%, P = 0.005; 0 [0, 10] vs. 7.5 [1.25, 25] min, P = 0.008). Remimazolam also showed better outcomes for lowest MBP (78 [73, 84] vs. 69.5 [66.25, 75.8] mmHg, P &lt; 0.001) and generalized ARV of MBP (1.42 \u00b1 0.49 vs. 1.66 \u00b1 0.52 mmHg\/min, P = 0.036). The remimazolam group required less phenylephrine (20 [0, 65] vs. 100 [60, 130] \u03bcg, P &lt; 0.001), less norepinephrine (162 [0, 365.5] vs. 1335 [998.5, 1637.5] \u03bcg, P &lt; 0.001), and more remifentanil (1750 [1454.5, 2184.5] vs. 531 [431, 746.5] \u03bcg, P &lt; 0.001) than the control group.Conclusions: Remimazolam anesthesia may provide better hemodynamic stability during cerebrovascular bypass surgery than propofol-induced and desflurane-maintained anesthesia.<\/jats:p>","DOI":"10.4097\/kja.24538","type":"journal-article","created":{"date-parts":[[2025,1,23]],"date-time":"2025-01-23T05:23:36Z","timestamp":1737609816000},"page":"148-158","update-policy":"https:\/\/doi.org\/10.4097\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Effect of remimazolam on intraoperative hemodynamic stability in patients undergoing cerebrovascular bypass surgery: a prospective randomized controlled trial"],"prefix":"10.4097","volume":"78","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8567-5514","authenticated-orcid":true,"given":"Chang-Hoon","family":"Koo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5788-2014","authenticated-orcid":true,"given":"Si Un","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1888-3596","authenticated-orcid":true,"given":"Hyeong-Geun","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3341-5029","authenticated-orcid":true,"given":"Soowon","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3396-3140","authenticated-orcid":true,"given":"Yu Kyung","family":"Bae","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3659-6171","authenticated-orcid":true,"given":"Ah-Young","family":"Oh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4157-2609","authenticated-orcid":true,"given":"Young-Tae","family":"Jeon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9331-5658","authenticated-orcid":true,"given":"Jung-Hee","family":"Ryu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2573","reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.3171\/2015.6.jns151105"},{"key":"ref2","first-page":"100","volume-title":"Moyamoya disease: a review of the disease and anesthetic management","author":"Parray","year":"2011"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1227\/00006123-199606000-00011"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1097\/00000542-199701000-00010"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1097\/aln.0000000000001015"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016\/j.bja.2020.07.050"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.4103\/0970-9185.169083"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.7150\/ijms.15390"},{"key":"ref9","volume-title":"","author":"Matsumoto"},{"key":"ref10","first-page":"636","volume-title":"Pharmacokinetics and pharmacodynamics of remimazolam (CNS 7056) after continuous infusion in healthy male volunteers: part I.
