Randomized Controlled Trial Comparative Study
Sonographic visualization and cannulation of the axillary vein in two arm positions during mechanical ventilation: A randomized trial.
Abduction of the arm has been used for ultrasound-guided infraclavicular axillary vein cannulation. We evaluated the influence of arm position on sonographic visualization and cannulation of the axillary vein in patients receiving mechanical ventilation. ⋯ Abducted position moved the clavicle cephalad and allowed sonographic visualization of infraclavicular axillary vein approximately 2 cm more proximally than with the adducted arm, with a comparable rate of cannulation success.
