The aim of this study was to explore the utility of using the new BIS-Vista monitor (Aspect Medical Systems, Newton, MA) for occipital sensor placement in the patients undergoing brain neurosurgical procedures during propofol-remifentanil anesthesia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Two BIS Quatro sensors (Aspect Medical Systems, Newton, MA) mounted on the occipital and frontal regions were connected to two BIS-Vista monitors at three anesthesia states: before induction, during anesthesia maintenance, and recovery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>There were significant differences before induction (P = 0.0002) and at anesthesia maintenance (P = 0.0014) between mean +\/- SD occipital (83.4 +\/- 4.8, 66.7 +\/- 7.2) and frontal (93.1 +\/- 3.4, 56.9 +\/- 9.1) BIS-Vista values. During anesthesia recovery, there was no difference (P = 0.7421) between occipital (54.6 +\/- 9.3) and frontal (53.1 +\/- 7.3) BIS-Vista values. Bland and Altman analysis revealed a BIS-Vista negative-bias (limits of agreement) of -9.7 (+1.1, -20.5) before anesthesia induction, +9.8 positive-bias (+22.8, -1.7) during anesthesia maintenance, and -0.9 bias (+10.9, -12.8) during anesthesia recovery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>We demonstrated that not only the regional limits of agreement are too wide to allow data of the two montages to be used interchangeably but also the variation is a function of anesthetic depth. However, keeping in mind a relatively consistent BIS-Vista -10 bias before induction and +10 bias during anesthesia maintenance with limits of agreement of approximately +\/-11 BIS units, approximately double the clinically acceptable less than 10 BIS units level of agreement, BIS-Vista off-label occipital montage might be helpful in following a trend of propofol-remifentanil anesthesia in individual cases where frontal access is particularly difficult.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1097\/aln.0b013e3181cf4111","type":"journal-article","created":{"date-parts":[[2010,2,17]],"date-time":"2010-02-17T02:31:01Z","timestamp":1266373861000},"page":"645-651","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":28,"title":["BIS-Vista\u2122 Occipital Montage in Patients Undergoing Neurosurgical Procedures during Propofol\u2013Remifentanil Anesthesia"],"prefix":"10.1097","volume":"112","author":[{"given":"Ashraf\u00a0A.","family":"Dahaba","sequence":"first","affiliation":[{"name":"Associate Professor."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ji\u00a0Xiu","family":"Xue","sequence":"additional","affiliation":[{"name":"Associate Professor, Department of Anaesthesiology."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guo\u00a0Guang","family":"Zhao","sequence":"additional","affiliation":[{"name":"Associate Professor, Department of Neurosurgery, Xuan Wu Hospital, Capital Medical University, Beijing, People's Republic of China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qing\u00a0Hai","family":"Liu","sequence":"additional","affiliation":[{"name":"Associate Professor, Department of Anaesthesiology."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guo\u00a0Xun","family":"Xu","sequence":"additional","affiliation":[{"name":"Associate Professor, Department of Anaesthesiology."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helmar","family":"Bornemann","sequence":"additional","affiliation":[{"name":"Associate Professor."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter\u00a0H.","family":"Rehak","sequence":"additional","affiliation":[{"name":"Professor, Biomedical Engineering and Computing Unit of the Department of Surgery, Medical University of Graz."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helfried","family":"Metzler","sequence":"additional","affiliation":[{"name":"Professor, Department of Anaesthesiology and Intensive Care Medicine."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R2-25-20251013"},{"key":"R3-25-20251013"},{"key":"R4-25-20251013"},{"key":"R5-25-20251013"},{"key":"R6-25-20251013"},{"key":"R7-25-20251013"},{"key":"R8-25-20251013"},{"key":"R9-25-20251013"},{"key":"R10-25-20251013"},{"key":"R11-25-20251013"},{"key":"R12-25-20251013"},{"key":"R13-25-20251013"},{"key":"R14-25-20251013"},{"key":"R15-25-20251013"},{"key":"R16-25-20251013"},{"key":"R17-25-20251013"},{"key":"R18-25-20251013"},{"key":"R19-25-20251013"},{"key":"R20-25-20251013"},{"key":"R21-25-20251013"}],"container-title":["Anesthesiology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/pubs.asahq.org\/anesthesiology\/article-pdf\/112\/3\/645\/249721\/0000542-201003000-00025.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/journals.lww.com\/00000542-201003000-00023","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,13]],"date-time":"2025-10-13T16:18:38Z","timestamp":1760372318000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.lww.com\/00000542-201003000-00023"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,3,1]]},"references-count":20,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2010]]}},"URL":"https:\/\/doi.org\/10.1097\/aln.0b013e3181cf4111","relation":{"has-review":[{"id-type":"doi","id":"10.3410\/f.2899956.2568054","asserted-by":"object"}]},"ISSN":["0003-3022"],"issn-type":[{"value":"0003-3022","type":"print"}],"subject":[],"published":{"date-parts":[[2010,3,1]]}}}
