“…This involves injecting a small amount (<10 mL) of saline that has been agitated with air and then had large air bubbles removed from the syringe. 19 When the catheter is properly placed, injection of agitated saline produces hyperechoic contrast within the lumen of the vessel, verifying the proper position. For central catheters, this can be performed while visualizing the right atrium of the heart, which may be improved by using a low-frequency transducer such as a curvilinear or phased array transducer.…”

“…Most clinical studies addressing ultrasound-based tip location of central venous access in adult patients have adopted 2.5-3.5 MHz sectorial probes (phased array). 15,24,[28][29][30][31][32][33][34] The subcostal four-chamber (longitudinal) view has been considered as the first choice in most studies 15,24,28,29,[31][32][33][34] : this view can be easily applied in patients with respiratory problems (mechanical ventilation, lung emphysema) but it may be difficult in some cases of previous surgery of the upper abdomen. 27,34 An alternative option is the fourchamber transthoracic apical view, which-on the other hand-may be difficult in obese patients 27,34 and in patients with acute or chronic lung disease.…”

“…Además, determina la adecuada ubicación de la punta del catéter venoso central con una sensibilidad del 70% y una especificidad del 100% con la prueba de solución salina 33 . Para toracentesis, la ecografía aumenta probabilidad de éxito y reduce el riesgo de punción de órganos 34 .…”
