Abstract:
Objective:To evaluate the effect of blunt separation method on peripherally inserted central venous catheters.Methods:The randomized controlled trials regard to the effect of blunt separation method on peripheral central venous catheters were retrieved from CNKI, Wan fang Data Knowledge Service Platform, CQVIP, CBM, Cochrane, PubMed, EMBASE and Web of science from January 2010 to March 2021, two researchers performed quality assessments and extracted data according to Cochrane evaluation manual standards. RevMan 5. 4 software was used for statistical analysis.Results:A total of 11 randomized controlled trials were analyzed, including 1379 participants. The meta-analysis results showed that there was no statistical difference in the successful rate of one-time sheath delivery ( OR=1.62, 95% CI 0.92-2.86, P>0.05). However, patients in blunt separation group showed lower blood loss ( OR=0.24, 95% CI 0.11-0.50, P<0.05), lower the incidence of seepage at puncture site ( OR=0.18, 95% CI 0.09-0.37, P<0.05) than those in traditional skin expansion group at 24h after catheterization, and less the time of maintenance within 7 days after catheterization ( MD=-0.95, 95% CI-1.78--0.11, respectively, P<0.05). Conclusions:Blunt separation method can significantly reduce the incidence of complications and the time of catheter maintenance. Due to the limited quality of included studies, more high quality studies are needed to verify the conclusions.
