简要总结
In this study, the investigators will investigate how patients' radial artery diameters change according to sex, age, height, weight and body mass index by measuring radial artery diameter using ultrasonography. The correlation of Allen test with doppler ultrasonography will also be evaluated.
详细描述
Arterial catheterization for continuous hemodynamic monitoring or frequent blood sampling is a common procedure in anesthesia and critical care setting. The most commonly used site for arterial catheterization is the radial artery because of its superficial course, alternate blood supply to hand via ulnar artery and a low rate of complications. Allen test is a simple, but not reliable, method for assessing the safety of radial artery catheterization. Intraarterial catheterization has some complications such as hematoma, vasospasm, arterial thrombosis, necrosis of skin overlying. Using larger size cannula from radial artery diameter, increase rate of complications. The purpose of this study is to investigate the corelation of radial artery diameter with sex, age, height, weight and body mass index for determination of proper cannula size and investigation of correlation between Allen test and doppler ultrasonography.

结局指标
主要结局
change of the radial artery diameter according to sex, age, height, weight and body mass index
时间窗: 5 minutes prior to anesthesia induction
Ultrasonography measurements will be performed with a linear probe. The non-dominant hand of the patient will be fixed in the anatomical position on the arm chair. The wrist joint of patient will be extended to 30 degree with a wrist pad. The Ultrasonography probe will be transversally placed 2 cm proximal to the styloid process and the short axes of the radial artery will be scanned. The diameter of the radial artery will be measured and recorded.
次要结局
- correlation between Allen test and doppler ultrasonography.(5 minutes prior to anesthesia induction)
- change of the radial artery diameter according to sex, age, height, weight and body mass index after the induction(5 minutes following to anesthesia induction)
