Purpose: To determine by ultrasound which access and position the child must stay to obtain the best transversal section of the right Internal Jugular Vein (RIJV) allowing a safer puncture.
Methods: Three possible accesses to the RIJV, anterior, lateral and posterior, from 57 healthy children, were analyzed through ultrasound images in a sequence of positions of the head, in supine position, with or without a roll under the scapula: head centered in neutral position with and without a roll (NPP and NP); contra lateral rotation with and without a roll (CLRP and CLR), neutral position and the patient raised in 30 degrees in Trendelenburg position (TDG). To analyze the results it was applied one statistic method, with variation analysis to the same individuals.
