Abstract:
Objective To study the efficacy of tourniquet to block the distal of radial styloid on success rate of radial artery catheterization.Methods One hundred and forty ASA Ⅰ-Ⅲ patients, aged 22-88 years,undergoing general anesthesia and requiring radial artery catheterization were in-cluded in this study and were randomly allocated into touch positioning group (group A)or tourni-quet-assisted group (group B).Radial artery catheterization was conducted after induction of general anesthesia in two groups.The invasive systolic blood pressure (ISBP ), invasive diastolic blood pressure(IDBP)and HR of patients were recorded in group B at 1 min before ischemia (T1 ),using pressure pulse blocking after 1 min (T2 ),2 min (T3 ),5 min (T4 )and the complete release of tour-niquet after 1 min (T5 ),5 min (T6 )and 10 min (T7 ).The first and total success rate of radial artery puncture,puncture times,puncture duration and complications were recorded.Results The radial ar-tery diameter was not statistically significant in group B between before and after blocking radial artery .ISBP at T2-T4 in group B was significantly higher than that at T1 (P <0.05).The first time puncture success rate and overall success rate in group B was significantly higher than that of group A,The number of puncture in group B was significantly less than that of group A,and puncture time was significantly shorter in group A (P <0.05).Conclusion Tourniquet-assisted radial artery cathe-terization could improve success rate,decrease puncture times and shorten puncture duration.
