Abstract
STUDY OBJECTIVE: To investigate the value of using a new technique for ultrasound-guided radial artery catheterization; oblique approach; vs transverse and longitudinal views are the traditionally used approaches aiming to combine benefits and avoid drawbacks of aforementioned approaches. DESIGN: A prospective randomized nonblinded study. SETTING:Gastroenterology Center, Mansoura University, Egypt from February 2015 to August 2015. PATIENTS: One hundred twenty-six surgical and intensive care unit patients indicated for arterial catheterization. INTERVENTION: Patients were randomly allocated into 3 groups according to the US-guided technique used; group T (n=42) using transverse view, group L (n=42) using longitudinal view, group O (n=42) using oblique view. MEASUREMENTS: Primary objective was overall success rate; secondary objectives were first attempt success, time to cannulate, and operator satisfaction with the used technique. MAIN RESULTS:Forty-two patients were included for each study group. Overall success rate of radial artery catheterization was significantly higher in group O than in group T and clinically higher than group L (60% for group T, 70% for group L, 90% for group O; P<.02). Likewise, time needed to cannulate the radial artery was significantly lower in group O than in both group T and group L (28±19 s for group T, 66±5 s for group L, 16±7 s for group O; P<.00]. CONCLUSION: These results support the conclusion that the oblique approach for US-guided radial artery catheterization may replace the 2 classic approaches owing to its superior success rate, higher first attempt success and shorter time consumed for catheterization with more operator satisfaction after the procedure.
