OBJECTIVE To investigate the clinical symptom of hospital infection in hematology ward and analyze the risk factors about hospital infection,so as to control occurrence of hospital infection.METHODS Using prospective and retrospective investigating methods,all sufferers in hematology ward of our hospital from Jan to Dec,2005 were made statistical analysis.RESULTS Hospital infection rate was 11.96% and case infection rate was 12.96%.The infected sites were mainly respiratory tract,oral cavity and urethra,occupied 76.92% of all cases.Main pathogenic bacteria were Candida albicans,Pseudomonas aeruginosa,Escherichia coli,et al.CONCLUSIONS The occurrence of hospital infection in hematology ward is related to hospitalization time,underlying diseases,peripherial leucocyte count and using of antibiotic medicament.Main measures for preventing and reducing hospital infection are symptomatic treatment to underlying diseases,suitably using broad spectrum antibiotics,improvement of hospitalization conditions and shortening of hospitalization time.

Objective To explore the adverse reactions of contrast-enhanced ultrasound and treatments of the adverse reactions. Methods 6035 patients examined by contrast-enhanced ultrasound were closely observed in the process and 20 minutes after the examination. The occurrence and clinical manifestations of adverse reactions were recorded. The patients were gave symptomatic treatments. Results Two of 6035 patients experienced mild adverse reactions related with contrast-enhanced ultrasound. The incidence rate was 0. 031% (2/6035). No moderate or serious adverse reaction occurred. The two patients recovered well after symptomatic treatments. Conclusions The contrast-enhanced ultrasound has high safety and low incidence rate of adverse reaction. Patients should be under close observation in the process of contrast-enhanced ultrasound. The symptomatic treatments should be gave in time.

Objective:To study the risk factors of venous thromboembolism(VTE)and the predictive value of the improved VTE score model to identify the risk of VTE in gynecological surgery patients.Methods:From Janu-ary 1,2020 to December 31,2022,41 patients with VTE after gynecological surgery were selected as the VTE group,and a total of 164 patients with adjacent gynecological surgeries during the same period were selected as the non-VTE group with a ratio of 1 :4.Univariate and multivariate Logistic regression analysis were used to ana-lyze the risk factors of VTE after gynecological surgery,and a modified VTE risk factor rapid assessment model(referred to as the improved VTE score model)was constructed.The receiver operating characteristic(ROC)curve was used to study the predictive value for VTE for in gynecological surgery,and compared with the Caprini score model(Caprini table for short).Results:①Multivatiate Logistic regression analysis showed that there were independent risk factors for postoperative VTE in gynecology surgery(OR＞1,P＜0.05),including age≥60 years,BMI≥28 kg/m2,malignant tumors,surgery time＞3 hours,history of thrombosis,and the increased D-di-mer difference before and after surgery.②The Area under Curve(AUC)of ROC was 0.963 in the improved VTE score model with a Youden index 81.10％,sensitivity 87.80％and specificity 93.29％.The AUC of the Caprini score model was 0.888 with Youden index 63.41％,sensitivity 73.17％and specificity 90.24％.The improved VTE score model the Caprini score model identified 92.68％and 85.37％of VTE patients as high-risk or ex-tremely high-risk,respectively,but the difference was not statistically significant(P＜0.05).Conclusions:More attention should be paid to the six independent risk factors for postoperative VTE in gynecology surgery.The two score models showed a similar identified level.However,the improved VTE score model is more simple and easier to operate,has better practicality,and has certain clinical promotion value.
