ABSTRACT

Objective To investigate the effect of edaravone pretreatment on myocardial injury induced by carbon dioxide pneumoperitoneum in patients undergoing laparoscopic gynecologic surgery.Methods Thirty patients undergoing laparoscopic gynecologic surgery,ASA Ⅰ or Ⅱ grade,were divided into two groups by random digits table with 15 cases eachcontrol group and edaravone group.Edaravone group following tracheal intubation received vein infusion of edaravone 0.5 mg/kg,control group received equal volume of 0.9％ sodium chloride.The carbon dioxide pneumoperitoneum pressure was maintained at 10-15 mm Hg (1 mm Hg =0.133 kPa).Venous blood samples were collected before anesthesia induction and after operation 8 h for the measurement of the serum creatine kinase (CK),creatine kinase-MB (CK-MB),aspartate aminotransferase (AST) and lactate dehydrogenase (LDH).Results The serum levels of CK and AST were significantly higher after operation 8 h in control group than those of before anesthesia induction in control group and after operation 8 h in edaravone group [(205 ± 27) U/L vs.(123 ± 25) and (123 ± 29)U/L,(48±5) U/L vs.(34 ±3) and (36 ±5) U/L,P＜0.05].There was no significant difference in the serum levels of CK-MB and LDH between two groups and the group (P ＞ 0.05).Conclusion Pretreatment with edaravone 0.5 mg/kg can protect myocardium in patients undergoing laparoscopic gynecologic surgery.
