Randomized Controlled TrialUsefulness of ultrasound guidance for central venous catheterisation in patients with end-stage renal disease.
Renal replacement therapy often requires the insertion of a central venous catheter. The procedure is invasive and can lead to a number of complications. To minimise the risk of such complications, ultrasonography is used. The aim of the present study was to assess the usefulness of ultrasound-assisted vs. traditional method of location of anatomical orientation points for the placement of central venous catheters. ⋯ The study findings did not demonstrate significant differences in the incidence of early complications during cannulation with and without ultrasound guidance. The first attempt success rate was found to be significantly higher in cases of ultrasound-assisted central venous catheterisation.

ReviewAssessment of three minimally invasive continuous cardiac output measurement methods in critically ill patients and a review of the literature.
In this study we compared the accuracy of three continuous cardiac output (CCO) measurement methods, with intermittent transcardiopulmonary thermodilution (TPTD-CO) as the gold standard. The three studied CCO measurement methods were: uncalibrated peripheral pulse contour measurement (FCCO), calibrated central pulse contour measurement (PCCO), and CCO obtained by indirect Fick principle (NCCO). ⋯ These results indicate that in our patient population, CCO can be most reliably monitored by calibrated central pulse contour measurements. All other methods appeared less accurate, especially in situations of low SVRI.
