Abstract:
Objective To explore the application values and the effect of myocardial preservation of right stellate ganglion block in off-pump coronary artery bypass grafting (OPCABG). Methods Sixty-two patients with ASA Ⅱ or Ⅲ,aged 50-75 years,scheduled for OPCABG were randomly divided into stellate ganglion block group (group SGB)and control group (group C)with 31 cases each.The patients in group SGB received right-lateral SGB before anesthesia induction.The medications and methods of anesthesia induction in the two groups were identical.Hemodynamics be-fore start of anethesia (T0 ),after induction (T1 ),after intubation tube (T2 ),after sternotomy (T3 ),at the beginning of bypass surgery for interrupted coronary artery (T4 ),at the end of coronary bypass grafting (T5 )were observed.Meanwhile,changes of serum cardiac troponin I (cTnI)and cre-atine phosphokinase MB (CK-MB)at T0 ,6 h (T6 ),12 h (T7 ),24 h (T8 )after operation were also observed.The operative time,the amount of drugs used and postoperative recovery were recored. Results MAP,HR of group SGB increased at T2-T5 compared with T0 ,and MAP,HR of group C significantly increased at T2-T5 comparing with T0 (P <0.05).Compared with those in group SGB, MAP,HR significantly increased at T2-T5 in group C (P <0.05 ).The Concentrations of cTnI and CK-MB of group C increased more obviously than those in group SGB at T6-T8 (P <0.05).Compared with group C,patients in group SGB needed less medication,less hospitalization time in ICU and had faster postoperative recovery.Conclusion SGB for patients during OPCABG stabilizes hemodynamy stability,further reduces myocardial injury,thus protecting myocardium.
