简要总结
The technique of blood samples extraction from the radial artery through an arterial catheter with a 3-way stopcock and automated washing with valve of fast flow is better than the one carried out through a fixed reusable arterial blood sample syringe and its manual washing because it shows a minor incidence of the complications originated from technical manipulation as infection, pseudo-aneurysm, ischemia or thrombosis of radial artery or obstruction of the catheter.
The purpose of this study is to evaluate the efficacy, in terms of adverse effects, of blood samples obtention using an arterial catheter with needless connector closed system or an arterial catheter with an arterial blood sample syringe.
Also a second purpose is to compare once a day (at the same time) the values of glycose blood levels between bedside glucometer determination of arterial catheter extraction and capillar puncture, and lab determination of glycose from venous puncture, in order to determinate fluctuation in glycose levels due to peripherical hypoperfusion or to vasoactive drugs received by these in-intensive care unit patients.
