Application of ropivacaine epidural anesthesia combined general anesthesia in thoracic operation

Objective: To investigate the safety and effect of epidural block with 0.375% ropivacaine combined with general anesthesia for thoracotomy.Methods: 60 cases with selective operation on lung cancer or esophageal cancer(ASA I-II) were randomly divided into GEA group(combined general-epidural anesthesia) and GA group(general anesthesia).MAP and HR were detected prior to induction of anesthesia(T0),immediately after intubation(T1),after skin incision(T2),during exploration(T3) and after extubation(T4).And the dosage of propofol,vecuronium and fentanyl,the time of consciousness and tracheal extubation were recorded.Results: Compared with GA group,MAP and HR at T1~T4 significantly decreased in GEA group,the same as the dosage of general anesthesia drug and the time of consciousness and tracheal extubation.Conclusion: 0.375% ropivacaine combined with general anesthesia can not only reduce the anesthetic dosage,quick awakening and extubation early,but also maintain hemodynamics steadily during the entire anaesthesia surgery process.
