Study Objective
To explore the influence of shoulder roll height on internal jugular vein (IJV) diameter and IJV/common carotid artery (CCA) overlap.Design
Cross-sectional study.
Setting
University-affiliated hospital.
Patients
40 healthy participants.
Measurements
Ultrasonography to measure the effects of using shoulder rolls ranging between 0 and 5 cm high on IJV diameter, CCA diameter, and percentage overlap of the CCA.
Main Results
The percentage overlap of CCA decreased for both left (LIJV) and right IJV (RIJV) with the use of higher shoulder rolls. Greater values were seen in depth from skin surface to anterior wall of left IJV in almost all stages, with the exception of Stages 0 and 1 (P < 0.016); and the use of a 5 cm shoulder roll resulted in a significantly decreased anteroposterior (AP) diameter of both RIJVs and LIJVs (both P < 0.008).
Conclusions
Shoulder rolls can reduce the overlap between the IJV and CCA, and may be useful in positioning patients for IJV puncture.
