Objective: To evaluate the analgesia effect of para vertebral nerve block (PVB) post nephrectomy. Methods: Sixty patients undergoing simple nephrectomy (age 35-65 years old, both genders, weight 45-80 kg, ASA grade I or II) were randomly divided into two groups using the table of random numbers: the control group and the PVB group, with 30 patients in each group. For both groups, patients were given intravenous infusion of ropivacaine 250 ml post operation and intravenous morphine patient-controlled analgesia. Six, 12, 24 and 48 hours post operation, blood gas analysis was conducted and VAS scores under quiet and exercising conditions were assessed. The cumulative morphine usage and cases of complications were calculated at 48 hours post : Compared with control group, PVB group had a significant higher PaO2 and lower PaCO2. There were significant differences in VAS scores under exercising condition while no difference under quiet condition between two groups. In PVB group, the cumulative morphine usage decreased, there were fewer cases of nausea, vomiting, pruritus and orthostatic hypotension, and the first flatus time post operation was shortened (P<). Conclusions PVB analgesia post nephrectomy may reduce the usage of morphine and the incidence of complications.问题：CEA的英文全称未给出，故翻译时未采用此缩写。方法中未说明PVB何时及如何实施。吗啡辅助镇痛没查到有assist的翻译，一般就直接说patient controlled analgesia，或其后加pump。

[ Abstract ]Objective: To evaluate the effect of continuous paravertebral analgesia after 60 patients who only did nephrectomy,aged between 30 and 65, and weighed from 45kg to 80kg in both ASA was I or II. The patients were also divided into two groups randomly: The control group (CEA group ) and the continuous paravertebral nerve block group (PVB group ). and each group has 30 patients. Both groups were injected with 250ml ropivacaine continuously, and adopted the intravenous morphine patient-controlled analgesia blood was tested, the VAS in still and in movement was evaluated seperatedly after 6/12/24/48 hours of teh nephrectomy, and the accumulated marphine usage and the cases of complication of the patients after 48 hours were : Compared with CEA, PVB has significant higher PaO2, has the same VAS in still state with the CEA while different VAS in movement, and the accumulated usage of marphine is , the PVB has less patients showing nausea,vomiting,pruritus and orthostatic. In addition, the patients in PVB have short interval (P＜) for the first flatus. Conclusion: Compared with CEA, using PVB for analgesia after the nephrectomy can reduce marphine usage and reduce related thoracic , amides ; pain after surgery ; analgesic我觉得我今天一定是心情大好....不然怎么会这么花时间去做这个呢....要不要用，你自己看着办吧...
