Abstract:
ObjectiveTo determine ff the cardiac index (CI) measured with FloTrac-Vigileo system agrees with that measured with pulmonary artery catheter (PAC).MethodsForty-three ASA Ⅱ or Ⅲ patients aged 53-75 yr weighing 46-100 kg undergoing off-pump coronary artery bypass grafting were included in this study.Anesthesia was induced with midasolam,sufentunil,propofol and rocuronium and maintained with propofol,remifentanil and atracurium.One MAC sevoflurane was inhaled at breast bone splitting and closing.CI was measured with FloTrac-Vigileo system and PAC before,and at 5,15 min of sevoflurane inhalation and recorded.All data were compared by Bland-Altman analysis and with kappa coefficient for agreement and percentage error was calculated.ResultsBland-Altman comparison of FloTrac-Vigileo system and PAC:matching data of 258 measurements:CI (2.8 ± 0.6 ) L· min - 1 · m- 2,bias was 0.23 L* min- 1 · m - 2 and limit of agreement was ( - 0.57,1.02)L · min- 1 · m- 2,resulting in κ ＝ 0.546 and an overall percentage error of 28.6 ％.ConclusionCI values obtained by FloTrac-Vigileo system agrees well with that obtained by thermodilution technique using PAC in patients undergoing off-pump coronary artery bypass grafting.
