Clinical Trial Summary

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%.

Description:

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.

Eligibility

Inclusion Criteria:

• patients who age bigger than18
• patients who have capillary fullness is good
• patients who have a central venous catheter
• patients who have an arterial catheter

Exclusion Criteria:

• patients who have predibatic will be excluded from the study. The research has been added to the exclusion criteria and has been changed both in the relevant field in the system and in the project application file. In the ADA (American Diabetes Association) definition of prediabetes, IGT (Impaired Glucose Tolerance) (140-200 mg/dl), lower IAG (Impaired Fasting Glucose) (100-125 mg/dl) and additional supplementation according to WHO (World Health Organization) It is based on the criteria of hemoglobin A1c (HbA1c: Hemoglobin A1c) between 5.7% and 6.4% (ADA,2014). Meeting one of the three criteria is defined as prediabetes. Prediabetes screening is performed using 75 g OGTT, HbA1C, FPG, or a 2-hour oral glucose challenge test.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Blood Glucose Measurement	In this comparison, the central venous catheter blood glucose measurement value will be taken as a baseline.	baseline
Secondary	Behavioral Pain Scale	The behavioral pain scale consists of three main variables including facial expression, upper extremity, and compliance with the ventilator. An increase in the obtained score indicates an increase in the level of pain. The first items in each sub-dimension describe the absence of pain, the second items describe mild, the third items moderate, and the fourth items describe increased pain levels. Each sub-dimension is scored between 1 (no response to pain) and 4 (complete response to pain). The lowest score obtained from the scale is 3 and the highest score is 12. As the score increases, the level of pain increases. The first items indicate no pain, the second items indicate mild pain, the third items indicate the presence of moderate pain, and the fourth items indicate the presence of severe pain. The behavioral pain scale has been proven to be valid and reliable for assessing pain in intubated patients in the ICU.	through study completion, an average of 1 year
Secondary	Visual Analog Scale	It is a one-dimensional scale used in the measurement of VAS pain. Among the one-dimensional scales used to determine the severity of pain in patients, it was determined that the VAS measures more sensitively and is more reliable. The scale consists of a 100 mm long horizontal line. On one end are the phrases "No Pain" and on the other end "Unbearable Pain" describing the most severe pain possible. The patient is asked to mark his pain on the scale. The length of the line from the starting point of the scale to the point marked by the patient is measured and recorded in mm. After capillary blood glucose measurement is made, the patients will be educated by the researcher about the use of VAS before the research and the patients will be asked to evaluate their pain using VAS. It will be recorded in the data collection form as the numerical value obtained by measuring the point where the patient marked on the scale.	through study completion, an average of 1 year
