The peripheral vein catheter pose is one of the  most frequently performed acts in intensive care. The superiority of ultrasound-guided peripheral perfusion on traditional manual tracking techniques is well demonstrated for difficult peripheral venous locating. The aim of our study was to compare two techniques for setting up peripheral vein in two transverse and longitudinal techniques, in terms of feasibility and complications.
Materials and methods: 60 patients were included in our study from July to September 2015, divided into two equal groups.
The identification of veins is performed using an ultrasound probe at high frequency flat head (7.5 Mhz) kind SonoSite vascular mode with use of doppler.las residents who have received theoretical and practical training, will trying to spot a peripheral vein in the upper limb and introduce a 18 gauge catheter. The procedure was performed in two different sections: transverse and longitudinal in the draw. We collected anthropometric characteristics of the patients, ultrasound locating times and the procedure, the number of attempts and the difficulty score evaluated 0-10.
Results: No difference between the two groups regarding the anthropometric criteria (weight = 74.4 ± 16.8 kg; height = 168.9 ± 18,6cm and BMI = 23.9 ± 2.7 kg / m²).

Difficulty Score 4.7 / 10 3.8 / 10 0.042
Patient satisfaction 8.3 / 10 8.5 / 10 0.47
Conclusion: Ultrasound can facilitate cannulation of peripheral veins that is either longitudinal or transverse cutting without any difference between the two techniques. It improves patient comfort us and makes life easier by reducing the time of peripheral venous access, reducing the number of attempts, and limiting the use of VVC.
