Abstract:
Objective To observe the effects of postoperative patient controlled epidural analgesia(PCEA) on plasma neuropeptide Y(NPY) Methods Fifty eight patients scheduled for thoracic surgery, were randomly divided into PCEA group(n=28) and control group(n=30) After operation, patient controlled epidural analgesia was applied in PCEA group and in control group pethidine I M was given intermittently The plasma NPY and serum cortisol concentrations were measured at pre anesthesia,the end of operation,and 24h and 48h after operation by radioimmunossay Results Compared with the baselines, plasma NPY and serum cortisol levels increased significantly at the end of operation in both groups ,without the obvious differences between both groups The plasma NPY level restored to the baseline in PCEA group 24h after operation, and in control group was significantly higher 24h after operation than the besaline and restored to the besaline 48h after operation The serum cortisol level was kept higher level 24h after operation and restored to the baseline 48h after operation in PCEA group, and in control group increased significantly 24h and 48h after operation as compared with the baseline The plasma NPY level 24h after operation and serum cortisol level 24h and 48h after operation were lower markedly in PCEA group than those in control group Conclusions The PCEA can effectively depress the increase of plasma NPY and serum cortisol induced by postoperative pain in patients undergoing thoracic surgery
