Objective To evaluate the effect of sevoflurane on left ventricular function in patients undergoing elective coronary artery bypass grafting (CABG) .Methods Thirty-five ASA Ⅱ or Ⅲ patients of both sexes (30 males, 5 females) aged 53-75 yr weighing 46-100 kg undergoing CABG were enrolled in this study. Transesophageal echocardiography (TEE) probe was placed. The TEE variables including cardiac index (CI), left ventricular short axis shortening (FS), left ventricular ejection fraction (LVEF), low propagation velocity ( Vp), E wave velocity (E) , A wave velocity ( A) , systolic wave velocity ( S) , diastolic wave velocity ( D), AR wave velocity, E/A ratio and S/D ratio were recorded before inhalation of sevoflurane (T_1 ) , and 5 min (T_2) and 15 rain ( T_3) after inhalation of sevoflurane after splitting of sternum, and before inhalation of sevoflurane (T_4 ), 5 min (T_5) and 15 min (T_6) after inhalation of sevoflurane after the closure of sternum. The end-tidal concentration of sevoflurane corresponded to 1 MAC. Anesthesia was induced with midazolam 0.05 nig/kg, sufentanil 0.5μg/kg and rocuronium 0.9 mg/kg and maintained with infusion of propofol at 4-6 mg·kg~(-1) ·h~(-1), remifentanil at 0.2-0.4μgkg~(-1)·h~(-1) and atracurium at 0.5 mg·kg~(-1)·h~(-1). The patients were mechanically ventilated after tracheal intubation (V_T 8 ml/kg, RR 12 bpm, I:E 1:2, FiO_2 70%-80% ) .Results (1) MAP and CI were significantly decreased at 5 and 15 min after sevoflurane inhalation. LVEF and FS were also decreased. (2) There was no significant change in diastolic function indexes after sevoflurane inhalation including E and A wave velocity, systolic wave velocity, diastolic wave velocity, E/A ratio and S/D ratio. (3) Cardiac function improved after CABG. CI, LVEF and FS were significantly increased after CABG as compared with preoperative values. Conclusion In patients undergoing elective CABG, sevoflurane (the end-tidal concentration corresponding to 1 MAC) can depress left ventricular systolic function but does not affect left ventricular diastolic function.
