Randomized Controlled Trial Multicenter StudyComplications in internal jugular vs subclavian ultrasound-guided central venous catheterization: a comparative randomized trial.
The use of real-time ultrasound (US) has been shown to reduce complications of central venous (CV) catheterization. However, complication rates have not been compared according to insertion points for CV catheterization using US. Accordingly, this study aimed to compare the complication rates of internal jugular vein (IJV) with those of subclavian vein (SCV) catheterization. ⋯ Results demonstrated that the complication rates of IJV and SCV catheterizations using US are very low, showing no superiority of the SCV approach compared to the IJV.

ReviewBrain ultrasonography: methodology, basic and advanced principles and clinical applications. A narrative review.
Brain ultrasonography can be used to evaluate cerebral anatomy and pathology, as well as cerebral circulation through analysis of blood flow velocities. Transcranial colour-coded duplex sonography is a generally safe, repeatable, non-invasive, bedside technique that has a strong potential in neurocritical care patients in many clinical scenarios, including traumatic brain injury, aneurysmal subarachnoid haemorrhage, hydrocephalus, and the diagnosis of cerebral circulatory arrest. ⋯ Its increasing use reflects a growing interest in non-invasive cerebral and systemic assessment. The aim of this manuscript is to provide an overview of the basic and advanced principles underlying brain ultrasonography, and to review the different techniques and different clinical applications of this approach in the monitoring and treatment of critically ill patients.
