In previous studies, ultrasound guidance and keeping in neutral head position have been recommended to increase the success rate and to decrease the overlap between carotid artery (CA) and IJV, respectively. However, devices for ultrasonography are not always available. Moreover, IJV catheterization without head rotation could be extremely difficult in infants because of relative the larger skull and the smaller neck than those of adults. Therefore, a simple method to relieve the overlap between CA and IJV would be needed.
