Dimensions of internal jugular veins in Turkish children aged between 0 and 6 years in resting state and during Valsalva maneuver

Topographical anatomy of central venous system in extremely low‐birth weight neonates less than 1000 grams and the effect of central venous catheter placement

“…In this series, the right internal jugular vein has a greater diameter than left. This could also be observed in a study performed in older children (Karazincir et al,2007). The reason for this observation remains unclear.…”

Internal jugular vein diameter in pediatric patients: are the J‐shaped guidewire diameters bigger than internal jugular vein? An evaluation with ultrasound

“…However, in the study by Karazicir et al. (6), significant correlations between age, weight, height, and RIJV diameter have been reported. Although they reported statistical significance, they did not give the level of significance by giving the correlation coefficients.…”

“…Previous studies have investigated IJV diameter either in the adults or in the children (1,3,6-9). Karazincir et al (6) investigated right or left IJV diameter of 94 children between 0 and 6 years old and found a mean RIJV anteroposterior diameter of 5.43 ± 2.07 mm in supine position. Unfortunately, they did not divide the patients into age subgroups, so one cannot assume which age group of patients might have an IJV diameter of 5 mm or lower.…”

“…Likewise, Alderson et al (11) in a study on children <6 years of age found poor correlations between RIJV diameter and patient's age (r = 0.259) or weight (r = 0.155). However, in the study by Karazicir et al (6), significant correlations between age, weight, height, and RIJV diameter have been reported. Although they reported statistical significance, they did not give the level of significance by giving the correlation coefficients.…”

The airway device preference may affect the overlapping of the common carotid artery by the internal jugular vein

“…The main limitation is the statistically significant differences in patient number and demographics, between Group laryngeal mask airway and Group ETT, caused by the allocation of the pediatric patients included in the study by the anesthesiologist responsible for the procedure. Although there was no selection bias to jeopardize the results of the study, as the diameter of IJV is correlated with the age, height, and weight in children (18)(19)(20), the outcomes of this study should be confirmed in a larger pediatric subpopulation in a randomized controlled trial. These differences in demographics might also have an effect on main findings of the study with respect to ETT insertion.…”
