Abstract:
Objective:To investigate the effect of ultrasound-guided midline catheter placement on the incidence of catheter-related bloodstream infection (CRBSI) in severe emergency patients.Methods:Five hundred and twenty-nine patients were chosen as the research objects from March 2018 to December 2019 at Emergency Intensive Care Unit, which was divided into the experimental group ( n=278) and the control group ( n=251). In the experimental group, ultrasound-guided midline catheter was used as central venous catheter (CVC) removal method of sequential, and in the control group, peripheral venous indwelling needle was used as sequential method after removal of CVC. CVC, midline catheter and the indwelling time of indwelling needle were counted. The utilization rate of CVC was compared between the two groups. Kaplan-Meier survival curve was plotted to describe the CVC indwelling time of the two groups and log-rank test was performed. Cox regression analysis was performed to analyze the influencing factors of CVC indwelling time and compare the incidence of CRBSI and other catheter-related complications. Results:The CVC indwelling time of the experimental group was significantly shorter than that of the control group (8 d vs. 13 d, P=0.000). The CVC utilization rate of the experimental group was significantly lower than that of the control group (49.83% vs. 80.45%, P=0.000). Multivariate Cox regression analysis showed that difficult intravenous access, length of ICU stay, the site of catheter placement, and midline catheter implantation without ultrasound-guidance were independent risk factors for prolonged CVC indwelling time ( P=0.000). The CRBSI rate of the experimental group was significantly lower than that of the control group (0.571‰ vs. 3.802‰, P=0.038). There was no significant difference in the incidence of other catheter-related complications between the two groups ( P=0.403). Conclusions:Ultrasound-guided midline catheter implantation can shorten the indwelling time of CVC, reduce the utilization rate of CVC, and reduce the incidence of CRBSI, which is worthy of clinical promotion.
