Objective To study the effects of use of cyclamic acid on monitoring D-Dimer and predicting deep venous thrombosis on lower limbs during total hip arthroplasty.Methods Ninety-three cases patients who received total hip arthroplasty operations at Joint Surgery Department of the Central Hospital of Zhuzhou city and Zhuzhou Hospital Affiliated to Xiangya Medical College of Central South University from December 2015 to May 2016 were selected as subjects and randomly assigned into study group with 50 cases and control group with 43 cases.During the operations,cyclamic acid was used intravenously and locally as a routine in the study group while saline was utilized instead in the control group.The D-Dimer was dynamically monitored before operation and 1,3,5,7,9 d after the operation,and venous color ultrasonography of both lower limbs were taken 3,6,9 d after the operation to check the conformation of thrombosis.Results The total blood loss after treatment in the study group was (350.5 ± 65.2) ml,intraoperative blood loss of (129.3 ± 43.1) ml,postoperative drainage volume of (80.9± 12.6) ml,occult blood loss of (141.9± 20.6) ml,corresponding to the control group were (560.8±60.6) ml,(208.9± 57.8) ml,(150.8 ± 18.9) ml,(202.9±23.9) ml.The above indicators were lower in the study group than in the control group,the differences between the two groups were statistically significant(t =16.02,7.59,21.24,13.22,P＜0.05).There were significant differences in terms of D2-dimer level of 1,3,5 d after the operation between the study group and the control group (P＜0.05),but at 7,9 d after the operation,the difference between the two groups were not statistically significant(P＞0.05).The study group and the control group at 9 d after operation with color Doppler ultrasound examination showed that there were 1 cases of patients with calf vein thrombosis both in two groups,there was no significant difference between the two groups(2.00％ vs.2.32％,x2 =0.012,P＞ 0.05).Conclusion The proper use of cyclamic acid can reduce blood loss and will not increase the risk of thrombosis.Monitoring dynamically on D-Dimer and deep venous color ultrasonography on lower limbs is helpful for early detection of thrombosis after total hip arthroplasty.However,the use of cyclamic acid during total hip arthroplasty will affect the monitoring on D-Dimer and therefore needs to be taken seriously.

Enhancement of health management capability and resource utilization efficiency of hospitals has become an imperative need to deepen the healthcare reform. The high-value consumables are subject to point-to-point accurate tracking based on code scan, relying on the hospital′s WeChat official account for WeChat-based management. The WeChat platform enables the system to automatically push the preset procurement plan to the mobile terminal of the managers via the low-inventory alarm at the departments. On the other hand, vendors can use their own mobile terminals to receive in time the plans, query product inventory, and last month invoicing information. These measures facilitate the hospital management on high-value consumables.

Objective: To construct and implement a calculation model of clinical nursing post classification. Methods: Between October to December 2018, head nurses of the hospital were screened as consultants, and Delphi method was used to determine the indicators, while the weights were assigned from the aspects of nursing workload, work quality, patient satisfaction and number of nursing night shifts. Combined with HIS data, the calculation model of clinical nursing post classification was constructed to classify clinical nursing units into different categories and levels. Results: After two rounds of expert enquiry, 82 nursing work items were identified and the objective weight assignment was determined ranging from 0.80 to16.14. According to the established calculation model and HIS data, nursing posts in clinical departments were classified into 6 levels and 3 categories, and the accurate management of clinical nursing post classification was achieved. Conclusions The construction of a calculation model is scientific and rigorous, which provides a scientific basis for dynamic nurse performance management and rational allocation of human resources. In addition, it provides a useful reference for accurate nursing management.
