Abstract:
Objective To observe the effects of combined generalepidural anesthesia on perioperative myocardial enzymogram and troponin T of the myocardium(cTnT)in old patients undergoing thoracic surgery.Methods Thirty-eight ASAⅠ-Ⅱ patients aged 60～80 years old were randomly divided into two groups.General anesthesia group(group G): anesthesia was induced with fentanly,propofol and vecuronium and maintained with isoflurane,propofol and vecuronium.Combined anesthesia group(group C):general anesthesia was performed as in group G and continuous epidural block with(1.6%) lidocaine was added during operation.Peripheral blood CK,CK-MB,AST,LDH and cTnT were measured before anesthesia,at the end of operation and at 6,24,48 hours after operation.Results Two groups could provide same postoperative analgesia.There was no change for HR,RR and MAP in two groups.Serum CK,AST,LDH and cTnT concentration in group G after operation were significantly higher than those before anesthesia(P
