ABSTRACT
Objective To evaluate the effectiveness and safety of multimodal postoperative analgesia of thoracotomy for malignant tumor excision.Method Sixty patients undergoing thoracotomy for malignant tumor excision were recuited.They were randomized into four groups:group A receiving single flurbiprofen axetil injection,group B using electronic analgesia pump for sufentanil PCIA,group C using electronic analgesia pump for dezocine PCIA and group D receiving sufentanil controlled by PCA-TCI system.Vital signs,artery lood gas analysis,PrinceHenry score,Ramsay score,remedial measure and untoward reactions were recorded.Results The falling down degree of Prince-Henry score of Group D was higher than those of Groups A,B and C (P ＜ 0.05).Reduction of Ramsay score of Group D was higher than those of Groups A,B and C (P ＜ 0.05).The number of the patients in Group D not undergoing Bolus remedial measure was larger than that of those in Groups B and C (P ＜ 0.05).Conclusion When referring to the effectiveness and safety of the models administrated the thoracotomy for malignant tumors excision,the analgesia model of PC A-TCI sufentanil (plasma target concentration:0.12～ 0.14 ng/ mL) used in Group D is superior to other models used in Groups A,B and C.Moreover,individual analgesia can be reached by the PCA-TCI sufentanil model.
