Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Purpose: It is one of the important nursing interventions for patients in intensive care units with strict glycemic protocol to determine whether glucose values are different for a bedside glucose meter compared to the main clinical laboratory and whether the blood sampling site has a significant effect on glucose values. In this study, it is aimed to compare whether there is a difference between blood samples from venous, arterial, capillary and thumb base region, which is defined as an alternative region to the fingertip, in blood glucose level measurement, and to compare the consistency between the thumb base region and fingertip region and pain and results of the different methods used.

Methods: The universe of the research consists of Bursa Uludağ University Health Practice and Patients will be hospitalized in the General Surgery Intensive Care Unit of the Research Center between April and September 2023. 125 patients who meet the sample selection criteria will form the sample of the study. The sample size of the study was determined statistically with the G\*Power (3.1.7) program. Comparison of blood glucose measurement taken with different methods in the power analysis to determine the sample size. When the effect size of blood glucose was determined as 0.9, it was calculated that a total of 125 patients should be included for a significance level of 0.05 and a power of 80%.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Purpose: In this study, it is aimed to compare whether there is a difference between blood samples from venous, arterial, capillary, and thumb base regions, which is defined as an alternative region to the fingertip, in blood glucose level measurement, and to compare the consistency between the thumb base region and fingertip region and pain and results of the different methods used.

Design: This is a quasi-experimental study with a single group and simultaneous (matched) sample will conduct to determine whether glucose values are different for a bedside glucose meter compared to the main clinical laboratory and whether the blood sampling site has a significant effect on glucose values.

A central venous catheter blood sample will be taken from the patient by the guideline recommendations and placed in the biochemistry tube and taken to the laboratory by the researchers. This result is studied by the "biochemistry-glucose test" laboratory.

A capillary blood sample (right/left fingertip; thumb base) from the same patient will be evaluated with a glucometer (Accu-check).

Finally, from the same patient, the transducer set to which the arterial catheterization is connected will first be washed with 5 ccs 1% heparin, and blood glucose will be measured by taking a blood sample from the catheter. Then, it will be washed with 10 ccs 1% heparin and a blood sample will be taken from the catheter and blood glucose measurement will be made. An arterial blood sample (right/left fingertip; thumb base) from the same patient will be evaluated with a glucometer (Accu-check).

The purpose of examining this difference is whether a routine transduce set washing has an effect on blood glucose measurement in blood samples taken from patients with arterial catheterization. In total, blood samples will be collected from 3 different sites (central venous catheter, capillary, and arterial catheterization) in the same patient. In total, with 5 different techniques from 3 different regions of the same patient;

ARTERIAL BLOOD SAMPLE i) Washing with 5 ccs 1% Heparin fluid ii) Washing with 10 ccs 1% Heparin fluid CAPILAR BLOOD SAMPLE iii) Right / Left Fingertip iv) Thumb base CENTRAL VENOUS CATHETERIZATION BLOOD SAMPLE will be collected.
