The application of general anesthesia combined with epidural block in patients undergoing thoracic surgery

Objective To study the influence of general anesthesia combined with epidural block on homodynamics and the revival time in patients undergoing thoracic surgery.Methods Forty patients undergoing thoracic surgery,ASA Ⅰ~Ⅱ were randomly assigned into two groups: general anesthesia group(group G) and general anesthesia combined with epidural block group(GE group).The same anesthesia agents were chosen to induce for all patients.The patients in GE group were punctured into epidural space though T_(4~5) or T_(5~6),The anesthesia plan was under T_(2~4)~T_(8~10) level.The homodynamic stander,revival time,the tracheal extubation time and the dose of anesthetic were recorded respectively before induction(T0),after tracheal intubation(T1),during skin incision(T2),2h after skin incision(T3) and after tracheal extubation(T4).Results There was no significant difference among the standers in the group GE+EA,while they increases in the group GA.The revival time and the tracheal extubation time in group GA was longer than the group GA+EA(P0.01);The doses of anesthetic in group GA are greater than those in group GA+EA(P0.01).Conclusion General anesthesia combined with epidural block can stabilize the hemodynamics and reduce the stress.It can be applied safely and effectively.
