Summary

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.

Conditions

• Critical Illness
• Hyperglycemia

Interventions

Type	Name	Description
PROCEDURE	Manual and automated washing of the peripherical lines	The extractions of the blood for the analysis of the glycaemia will be made puncturing the needless connector inserted in the distal 3-way stopcock key once an hour during 48 hours. Obtain 2cc of blood using the arterial blood sampling syringe connected to the proximal key. This volume of rejection is reserved in the syringe itself. In accordance with the current protocol of disinfection, the needless connector inserted on the distal key will be disinfected. With a disposable sterile syringe the needless connector is punctured and a minimum blood amount is obtained for the determination of the glycaemia. Once the sample has been obtained, the rejection volume reserved is returned to the bloodstream. This arterial blood sampling syringe is cleaned aspirating serum manually in order to wash the line. Additional line washing is made through the fast flow valve of the system BD DTXPlus ™.
PROCEDURE	Automated washing of the peripherical lines	The extractions of the blood for the analysis of the glycaemia will be made puncturing the needless connector inserted in the distal 3-way stopcock key once an hour during 48 hours. In accordance with the current protocol of disinfection, the two needless connectors inserted on the two 3-way stopcock keys will be disinfected. With a disposable sterile syringe the needless connector on proximal 3-way stopcock is punctured and 2cc of blood are aspirated. This volume of rejection is reserved in the syringe itself and it is not disconnected. With a second disposable sterile syringe the needless connector on distal 3-way stopcock key is punctured and a minimum blood amount is obtained for the determination of the glycaemia. Once the sample has been obtained, the rejection volume reserved in the disposable syringe connected to the proximal 3-way stopcock is returned to the bloodstream. Line washing will be made through the fast flow valve of the system BD DTXPlus ™.
