ABSTRACT
Objective To compare clinical effectiveness of real-time ultrasound-guided axillary-subclavian vein catheterization with that of the traditional technique.Methods A total of 142 patients who were intended to receive central venous catherization puncture,73 males and 69 females,aged 19-85 years,were randomly divided into two groups:traditional puncture of body-surface localization group (group T,n=71);real-time ultrasound-guided puncture group (group U,n=71),the probe was placed at the midline of the collarbone,30-40°horizontal to the clavicle,forming approximately a 60°angle between the longitudinal section of the probe and the coronal plane of the human body, showing the long axis of vein clearly,then in the long axis view puncture was performed.Time re-quired for catheterization,the number of needle advances and complications were recorded.The first-time success rate and the second-time success rate and failure rate were calculated.Results Puncture time of group U was significantly shorter than that of group T [(5.02±2.05)min vs (14.02±3.98) min,P<0.05].The first-time success rate of group U were higher than that of group T (95.8% vs 67.6%,P <0.05).The complication rate of group U was lower than that of group T (P<0.05). Catheter misplacements did not differ between the two groups.Conclusion Real-time ultrasound guided axillary-subclavian vein puncture is superior to the traditional technique and is worthy of clinical promotion.
