Abstract:
Objective To evaluate the effects of blood withdrawal from peripheral intravenous catheters (PIC) on blood samples via meta-analysis.Methods We performed a systematic search in Cochrane Library,PubMed,EBSCO,CINAHL,Embase,CMBdisc (China Biology Medicine disc),Wan Fang Data,VIP (China Science and Technology Journal Database),CNKI (China National Knowledge Infrastructure)to collect randomized controlled trails (RCTs)about the effects of blood withdrawal from peripheral intravenous catheters.The quality of RCTs was critically appraised and data were extracted by two reviewers independently.Meta-analysis was conducted for eligible RCTs.Results Totally 22 studies were retrieved and 7554 blood samples were included.Results of meta-analysis showed as compared with standard blood drawn by direct venipuncture (DVP),there was no significant risk of hemolysis rates of blood samples collected from PVC [random effect RR =2.01,95％ CI (1.01,4.00),P=0.05];with certain procedures,results of laboratory tests of blood samples withdrawal from PIC had little impacts on red blood cell count(RBC),white blood cell count(WBC),platelet count (PLT),fasting blood-glucose(FBG)and serum levels of sodium,potassium,calcium,chlorine,and the differences had no statistical significance (P＞0.05).Conclusion Blood samples withdrawal from PIC will not increase hemolysis if sampling after infusion has been stopped for 2～3 min and 2～5 ml blood is discharged,which are reliable for blood routine and biochemical tests.After a comprehensive consideration,the technique of blood withdrawal from a PIC could be used interchangeably from DVP.
