A Randomized Study Evaluating the Role of Ultra-sound Guidance When Drawing Radial Arterial Blood Samples

Skin disinfection by local antiseptic. Identification of the radial artery by palpation. Insertion of the needle positioned at 70 ° with regard to the artery palpated. Check the rise of arterial blood in the syringe.

Skin disinfection by local antiseptic. Application of sterile gel. Identification of the artery via ultrasound vascular probe. Center the artery at the center of the screen. Introduction of the syringe at 70 ° with respect to the probe, in center of visualized zone. Check the rise of arterial blood in the syringe.
