Abstract:
Objective To assess the clinical application effect of pocket-sized ultrasound-guided radial artery cannulation.Methods Two hundreds and ten patients undergoing elective surgery,146 males and 64 females,aged 18-70 years,ASA physical status Ⅰ-Ⅲ,were scheduled for radial arterial catheterization.The patients were randomly divided into three groups (n =70 each):control group (group C),pockevsized ultrasound group (group U1) and conventional portable ultrasound group (group U2).In group C,the radial artery catheter placement were performed by traditional palpation method.In group U1,the radial artery cannulation were achieved by GE Vsacn pocket-sized ultrasound guidance.In groups U2,the ultrasound-guided radial artery catheterization were completed by conventional portable ultrasound.Before radial arterial cannulation,the diameter of radial artery and the distance between skin to artery in ultrasound images were measured and recorded.The first attempt success rate,cases that punctured less than 3 times,the number of attempts,successful cannulation time and potential complications were recorded.Results There was no statistic significant difference in the hemodynamic parameters,the diameter and the depth of radial artery among three groups.Compared with group C,patients in the other groups had higher first attempt success rate and greater proportion of cases that punctured less than 3 times,fewer placement attempts,shorter catheterization time,and lower incidence of the complication of hematoma (P＜0.05).There was no significant difference between groups U1 and U2 among these characteristics.Conclusion Ultrasound is a valuable adjunct to radial arterial catheter insertion.The pocket sized ultrasound may be a good alternative option to guide radial artery catheter placement.
