Objective To explore the application of ultrasound-guided femoral and sciatic nerve blocks combined with general anesthesia in lower limb fracture surgery.Methods Sixty four patients who received orthopaedics surgerywere randomly divided into two groups including combined group(n =32),control group (n =32).Control group was given general anesthesia alone,combined group was givengeneral anesthesia combined with ultrasound-guided femoral and sciatic nerve blocks.The intraoperative hemodynamic state at different time,anesthetic dosage,and agitation after waking upbetween two groups were compared.Results Compared with T1 moment,HR and MAP at T2 moment in both groups were significantly decreased (P ＜ 0.05),while all these indicators at T3-T5 moment had no significant difference compared with the T1 moment in combined group (P ＞ 0.05),while the difference was significant in control group (P ＜ 0.05).Compared with control group,combined group had less intraoperative propofoland fentanyl dosage during the surgery,shorter awakening timeand extubation time,and the difference had statistical significance (P ＜ 0.05).The incidence of agitation after waking up and degree of agitation was significantly decreased in combined group than that in control group (P ＜ 0.05).Conclusion Ultrasound-guided nerve blockade combined with general anesthesia for lower limb fracture surgery,canmaintain the stability of intraoperative hemodynamics,reduce the dosage of analgesic drugs,and promote early awakening and extubation.

Objective To study the effect of total knee arthroplasty after limb position on postoperative hemorrhage,to provide basis for clinical diagnosis and treatment.Methods 270 cases of total knee arthroplasty were selected.The patients were divided into groupⅠ,group Ⅱand group Ⅲ according to the random number table method, 90 cases in each group.Patients of group Ⅰ with limb hip and knee were straight,group Ⅱ hip joint elevation of 45 degrees,70 degrees of knee flexion,group Ⅲ hip joint elevation of 45 degrees,the knee extension.All the patients were intervened for 12h after operation,were placed drainage bag 24 hours.The lead flow,preoperative,postoperative hemoglobin and 5 days after the knee joint activity were compared in the three groups.Results Induced flow after surgery in group Ⅰ was (433.4 ±25.3)mL,which was significantly higher than (402.6 ±19.6)mL and (403.5 ± 21.5)mL in group Ⅱand group Ⅲ,and the differences were statistically significant (t =5.253,5.301,all P 0.05).The hemoglobin levels of the three groups were (92.3 ±4.2)g/L,(114.9 ±6.4)g/L and (113.2 ±7.5)g/L,which were significantly decreased after operation,the differences were statistically significant compared with before operation (t =5.083, 6.034,7.893,all P 0.05).There was no significant difference of range of motion in the three groups after 5 days of operation (P >0.05).Conclusion Hip flexion can effectively reduce bleeding after total knee arthro-plasty,the flexion and extension of knee joint had no significant effect on postoperative hemorrhage.

Objective To investigate the clinical effect of modified storage type of autologous blood transfu-sion combined with shed blooding retransformation technique after OrthoPAT for artificial total knee arthroplasty. Methods 70 patients with total knee replacement were randomly divided into observation group and control group, 35 cases in each group.The observation group was treated with the modified storage autotransfusion combined shed blooding retransformation technique after OrthoPAT,while the control group was given conventional allogeneic blood transfusion.The hemoglobin values and blood coagulation function of the two groups at immediately before anesthesia and surgery,10min before autologous blood transfusion and after reinfusion of 15min,after 6h and 24h of surgery were recorded,and the drainage blood total value,allogeneic blood transfusion measurement issues and transfusion rate after 24h were recorded.Results The hemodynamics of the two groups were stable at each time,there were no difference at urine volume (all P >0.05).The coagulation conditions were normal of the two groups at each time,there were no statistically significant differences between the two groups (all P >0.05).The average volume and homologous blood transfusion rate in the observation group were (126.3 ±6.5)mL,1 /35,which were significantly lower than those in the control group [(476.4 ±10.6)mL,2 /35],the differences were statistically significant (t =10.73,χ2 =6.31,all P <0.05).The incidence rate of postoperative complication of the observation group was 5.7%,which was signifi-cantly lower than 22.9% of the control group,the difference between the two groups was statistically significant (χ2 =4.93,P <0.05).Conclusion The improved storage type of autologous blood transfusion combined with shed bloo-ding retransformation technique after OrthoPAT has exact effect for artificial total knee arthroplasty,the incidence of adverse reactions is low,as well as the low blood transfusion rate.
Résumé
Objective:To analyze the benefit incidence and evaluate the implementation effects on catastrophic disease insurance under the New Rural Cooperative Medical System ( NRCMS) in Jilin Province and put forward sug-gestions to perfect the catastrophic disease insurance under NRCMS. Method: In-depth interviews with related staff were conducted to gain an understanding of the operating status of catastrophic disease insurance under NRCMS;cat-astrophic disease patient data of Jilin Province from 2013 were collected, with a comparative analysis of implementa-tion effects among nine districts;the benefit incidence was analyzed by means of the Sperman rank correlation analy-sis; Results: The policy of catastrophic disease insurance under the NRCMS exhibited sound implementation effects and played an important role in reducing the economic burden of catastrophic disease patients. The average individual expenditure decreased by 4336. 52 yuan, while the reimbursement rate increased by 11. 15% after NRCMS cata-strophic disease insurance reimbursements. Additionally, statistical analysis results showed that there was a weak cor-relation between benefit incidence and economic level, the benefit equality of catastrophic disease insurance under NRCMS was relatively good, but the benefit level of rich patients was slightly higher. Conclusion:The reimbursement scheme of catastrophic disease insurance under NRCMS should be refined and improved, and the benefit fairness of different districts must be ensured, thus achieving the goal of relieving the“poverty caused by illness” phenomenon.
