Lactate as a Predictor in Severe Pneumonia

of head by 30 degrees gave significant differences in both RIJV and LIJV during deep breath (both p<0,001), and Trendelenburg position (both p<0,001) vs no maneuvers. The 45-degree leg lift increased the CSA only in RIJV(p=0,024). Conclusions. The mean CSA of RIJV is significantly larger, although both the RIJV and the LIJV are prone to CSA enlargement during deep breath, 45-degree leg lift, 10-degree Trendelenburg position even with a greater extent when head rotation of 30-degrees is achieved, thus these maneuvers can be used to facilitate IJV catheterization using both ultrasound guided or anatomical landmark technique.
