Effects of different analgesia model on analgesia and quality of sleep in patients after lower limb surgery

Objective To compare two commonly used methods for analgesia: PCIA(patient-controlled intravenous analgesia) and PCEA(patient-controlled epdural analgesia),and their effects on analgesia and quality of sleep in patients after lower limb surgery.Methods 80 cases patients with elective lower limb surgery under general anesthesia were analyzed.The patients were divided into four groups,including I1 group treated with tramadol hydrochloride and fentanyl citrate,I2 group treated with tramadol hydrochloride,fentanyl citrate and granisetron hydrochloride,E group treated with PCEA after surgery and C group injected with pethidine 1 mg/kg on demand after surgery.The general situation of patients,the analgesic effect and sleep state were observed.Results At the first and second days after surgery,the VAS of the analgesia group was significantly lower than that of the control group.The analgesic effect of group E was significantly better than that of group I1 and group I2.The VAS between the Group I1 and Group I2 was no significant difference(P0.05).At the third day after surgery,the VAS between the Group I1,Group I2 and the control group was not significantly different(P 0.05).The VAS between the group E and the control group or group I1,group I2 were significant different,analgesic effect of group E was superior those three groups(P0.01),while the VAS between group I1 and group I2 was not significantly different(P0.05).The rate of four groups patients' sleep state were compared with X2 segmentation method.Result of which was on the first days the rate of patients with good sleep at night of group I1 after surgery was significantly lower than the other three groups(P0.01).There was no significant difference among the remaining three groups(P0.05).Conclusion For lower limb surgery patients,epidural analgesia is better than intravenous analgesia.
