A transducer holder to perform continuous echocardiography has been recently described and the device has a major potential for use in anesthesiology.11 Song H, Tsai SK, Liu J. Tailored holder for continuous echocardiographic monitoring. Anesth Analg. 2018;126:435-7.,22 Alrayashi W, Kelleher S, DiNardo J, et al. Hands-free continuous transthoracic echocardiography: a contemporary evolution of the precordial stethoscope. Paediatr Anaesth. 2021;31:616-8. To improve daily practice, we developed a hydraulic arm coupled to a 3D-printed device capable of holding any commercially available ultrasound transducer (Fig. 1). Thus, the device enables the continuous assessment of cardiac output during surgery33 Souza RS e, de Melo WB, Freire CMV, et al.

(Fig. 2). Furthermore, the arm has successfully allowed effective continuous transcranial Doppler monitoring (Fig. 3).
Technical project for 3D printing of the device that connects the hydraulic arm to the ultrasound transducer.
Use of the device to capture echocardiography imaging from the apical 5-chamber window and the alignment of the Doppler to measure flow through the left ventricular outflow tract.
