Objective To comprehend the application of intravenous transfusion instrument in grade three hospitals of GuangZhou,and promote the use of trochar.Methods Using the questionnaire survey,we investigated the application of intravenous transfusion instrument in 12 grade three hospitals within 24 hours on October 10th to 11th in 2012,and then collected all data for analysis.All personnel participated in the investigation were given training to ensure the accuracy of the data collection.Results 9 732 patients needed to receive intravenous therapy,among whom 3 866 patients chose scalp acupuncture and 4 195 patients chose vein detained needle.We divided all the patients who had scalp needle and vein detained needle by age.The utilization of vein detained needle was higher than scalp acupuncture in the patients of ＜19 years old and ＞70 years old,but the utilization of scalp acupuncture was higher than vein detained needle in the patients of 19～70 years old.The difference of choosing intravenous transfusion instrument among different age groups had statistical significance.Conclusions Patients of 19～70 years old are in young and maturity phase,middle age,old age.The compliance of them is lower than other patients.They think the vein detained needle influence their daily activities and individual image,and also worry about infection.So they do not actively use vein detained needle,except when having poor situation in peripheral venous.Nurses are lack of health education,and fail to allow patients actively choose vein detained needle.

Objective To reduce the incidence rate of hospital-wide indwelling needle catheter blockage through a nursing project.Methods We set up a nursing project team,conducted a cross-sectional survey to know the using status of hospital-wide catheter,and analyzed the reasons of catheter blockage by root cause analysis method. "Reducing the incidence rate of hospital-wide indwelling needle catheter blockage" was established as the theme;improvement activities of nursing project were planned and developed for six months;and improvement methods were developed and implemented.Results The incidence rate of hospital-wide indwelling needle catheter blockage reduced to 3.6% from 8.1% (χ2=752.177,P<0.01),which reaches the goal of controlling the incidence rate of catheter blockage below 4%,and continuously decreases month by month. After implementation,the score of knowledge questionnaire about indwelling needle catheter blockage of nurses in the wards increased from (78.23±7.14) to (96.4±1.48) (t=54.735,P<0.01).Conclusions The nursing project obviously improves the degree of mastering the knowledge about preventing blockage,and reduces the incidence rate of hospital-wide indwelling needle catheter blockage.

The mini-midline catheter is a new technology for catheter placement that opens up a new field of peripheral venous access devices(PVADs)and plays an important role in the intravenous treatment of patients with fragile vasculature and difficult intravenous access(DIVA).Mini-midline catheter is more economical and easier to puncture than midline catheter,longer retention time than short cannula,lower catheter-related complications,it is the preferred solution for venous vascular access device(VAD)in short-to medium-term infusion and has been widely used in intravenous infusion abroad.Domestic research and application of this technology are still in the exploratory stage,and the specifications,guidelines and expert consensus for mini midline catheters have not yet been released,and there is a lack of standardized operation procedures,indications,contraindications and other guidelines.More studies with higher quality and multi-center linkage cooperation need to be carried out to provide a theoretical and practical basis for the formulation of industry standards for mini midline catheters in line with clinical practice.The definition,attributes,innovation,indications,advantages and disadvantages of the mini midline catheter were reviewed,so as to provide reference for clinical application.
