Venipuncture Versus Peripheral Catheter: Do Infusions Alter Laboratory Results?

摘要: Introduction Our aim was to evaluate the equivalence between analytic parameters from blood samples obtained a saline solution lock device used for infusion of drugs and those venipuncture. In our emergency department, patients bearing have extracted by venipuncture avoid possible contamination sample. Methods Adults department with who required laboratory tests were selected as candidates this cross-sectional observational study. Infusions halted flushed 0.9% solution; 2 minutes later, mL drawn discarded, corresponding tubes filled. Immediately after, another sample withdrawn opposite extremity Both analyzed hematology, biochemistry, venous gases, coagulation parameters. Concordance evaluated use intraclass correlation coefficient its 95% confidence intervals; Bland-Altman plots illustrate percentage differences exceeding SDs. The mean also checked detect laboratory's systematic error. Results An over 0.9 achieved all except pH, partial pressure carbon dioxide, oxygen. Differences SDs found in fewer than 10% None them exceeded 3 SDs, pH gases. All showed below accepted error Discussion Blood peripheral catheter or without drug infusions are valid analysis but not Nurses should know benefits using an existing drawing even when infusing commonly drugs. Emergency nurses consider collecting specimens access regardless type administered, because it is safe, simple, fast technique, which time efficient treating limited sites. This procedure reduces patient discomfort risk complications related venipunctures.
