Effects of different analgesia regimens on early post-operative cognitive dysfunction in elderly patients undergoing radical resection of cervical carcinoma

摘要

This study was designed to compare the effects of epidural and intravenous analgesia on early post-operative cognitive dysfunction (POCD) in elderly patients undergoing radical resection of cervical cancer. For this purpose, 74 patients aged 60-78 years [body mass index (BMI), 18-25 kg/m2; American Society of Anesthesiologists (ASA) classification score of I-III) undergoing radical resection of cervical cancer were divided into the epidural group (group E) and parenteral group (group P) groups (37 patients in each group). All patients underwent their surgical procedures under epidural anesthesia and intravenously-delivered general anesthesia. Patient-controlled analgesia (PCA) was supplied for 72 h after the surgery. Epidural analgesia was provided for the patients in group E and intravenous analgesia was provide for those in group P. General patient information was recorded and peripheral blood neutrophil counts, C-reactive protein (CRP) levels and interleukin (IL)-6 concentrations were measured immediately prior to the surgery (To), and at 24,48 and 72 h after the procedure (T,,T2 and T3, respectively). Visual analog scale (VAS) scores were also recorded at T,, T2 and T3, and the mini-mental state evaluation (MMSE) scores atT0, T,,T2,and T3 were calculated. Patients were diagnosed as having POCD according to their MMSE score differences between the peri-operative and post-operative values. The results revealed that the levels of CRP and IL-6 significantly increased in both groups after the surgery (T,.3). However, the CRP and IL-6 levels in group E were significantly lower than those in group P at all time points examined (P<0.05).
