Abstract:
ObjectiveTo investigate the effects of ederavone on oxidative stress response during one-lung ventilation (OLV).MetihodsThirty ASAⅠ or Ⅱ patients of both sexes aged40-64 yr,weighing50-85 kg undergoing elective esophageal cancer resection were randomly divided into 2 groups ( n =15 each):control group (group C) and edaravone group (group E).In group E edavavone was infused immediately after tracheal intubation at 60.0 mg/h for 30 min.Then the infusion rate was reduced to7.5 mg/h and maintained until the end of operation.In group C equal volume of normal saline was infused instead of edaravone.Arterial and venous blood samplea were taken immediately before skin incision,at 30 min of OLV and 30 min after re-expansion of the collapsed lung for blood gas analysis and determination of serum MDA and 8-iso-PGF2a concentrations.PaO2/FiO2,PA-aDO2 and respiratory index (RI) (RI =PA-aDO2/PaO2 ) were calculated.ResultsPA-a DO2,RI and serum concentrations of MDA and 8-iso-PGF2a were significantly lower at 30 min after re-expansion of the collapsed lung in group E than in group C( P < 0.05).ConclusionEdaravone can attenuate oxidative stress response during OLV.
