The Effect Of Feed-forward Control Tracking Method On Reducing The Blockage Rate Of Intravenous Indwelling Needle Was Observed

Objective:This study combines two management methods,feed-forward control method and tracking method,and applies them to the management of intravenous indwelling needle infusion.The aim is to reduce the incidence of indwelling needle blockage in the process of intravenous indwelling needle infusion.Using scientific management methods,we can provide quality control system for the whole process of venous indwelling needle infusion treatment,so as to reduce the occurrence of venous indwelling needle blockage.Method:Parallel controlled interventional experimental research methods were used.896 patients treated with intravenous indwelling needle in our hospital from January 2018 to June 2018 were selected for the study.The patients were randomly divided into two groups according to the order of admission:single observation group and double control group.The control group was administered with traditional nursing technology and routine nursing,which included reasonable maintenance during indwelling needle.At the same time,the patients were educated in various ways,such as oral,written and video.On the basis of traditional indwelling needle nursing,the observation group used feed-forward control method and tracking method to intervene effectively in patients with indwelling needle.The tracing method is patient-centered,through systematic observation and understanding of the patient’s treatment process,to implement the whole process management method for patients with high risk of blockage.According to the characteristics of different specialties,different diseases,different infusion,and so on,in accordance with the characteristics of patient’s diseases and the principle of descending the ladder,the patients with critical condition,poor vascular condition,long-term infusion and high-risk patients with venous indwelling needle occlusion were selected as tracking objects.Each Department identified 2-4 patients as the target of follow-up.Through case tracking and systematic tracking,the specific factors of high risk of blockage were identified,and effective management measures were implemented.Observe and record the incidence of blockage and swelling of indwelling needle in two groups.Result:(1)Comparison of baseline data between the two groups:896 patients were included in this study,852 patients were collected,424 patients in the control group and 428 patients in the observation group.There was no significant difference between the two groups in basic data such as age,sex,puncture site,vascular condition,type of infusion drugs and classification of diseases(P>0.05),which was comparable.(2)Comparing the incidence of blockage of venous indwelling needle between the two groups(the incidence of blockage of indwelling needle=(the number of blockage of indwelling needle per unit time/the total number of indwelling needle per unit time)*100.00%):the number of blockage of observation group was 11(2.6%)and that of control group was 32(7.6%).The difference was statistically significant(c~2=10.69,P=0.001).(3)Comparing the incidence of puncture site redness and swelling between the two groups(the puncture site of patients showed redness and swelling,pain and hardening of the puncture site,one or more of the above were considered as puncture site redness and swelling).The incidence of swelling in the observation group was 15(3.5%)and that in the control group was 35(8.3%).The difference was statistically significant(c~2=8.70,P=0.003).(4)Comparing the indwelling time of venous indwelling needle between the two groups:the indwelling days of the observation group were 5.4±0.9,the indwelling days of the control group were 2.1±0.7,and the Z value was equal to 4.60,P<0.001,the difference was statistically significant.(5)Comparison of single score before and after indwelling in the two groups:the pre-indwelling score of the observation group was 8.9±1.0,the pre-indwelling score of the control group was 8.9±1.2,and the Z was 1.62,P=0.11.There was no significant difference between the two groups.The score of observation group was 1.3±1.1,that of control group was 1.5±1.5,and that of Z was 0.28,P=0.78.There was no significant difference between the two groups.Conclusion:(1)The combination of feed-forward control method and tracking method has a significant effect on reducing the incidence of venous indwelling needle occlusion,which is worthy of multidisciplinary application and promotion.(2)The combination of feed-forward control method and tracking method has a significant impact on reducing redness,swelling,pain and hardening of the puncture site of patients with venous indwelling needle,alleviating the pain of patients and improving their comfort.(3)The combination of feed-forward control method and tracking method can significantly improve the indwelling time of venous indwelling needle,reduce the pain caused by repeated puncture,and reduce medical costs.Enhance the feeling of seeing a doctor.
