简要总结
Comparison of two techniques of central venous cannulation of subclavian vein using ultrasound was performed. ultrasound guided central venous cannulation is the standard practice today but its use in subclavian vein is technically challenging and not much literature is available. In this study 96 Patients were randomized into one of the groups and compared for various outcomes. The primary outcome studied was the time taken for procedure. Secondary objectives included comparison of total access time using both the techniques,comparison of first attempt success rate, comparison of the quality of needle visualization and the comparison of immediate (mechanical) and delayed complication rates.
