Jugular Venous Flow Neurosurgical Patients

NCT02002507 · Status: WITHDRAWN · Type: OBSERVATIONAL

Last updated 2022-12-22

No results posted yet for this study

Summary

Our hypothesis is that there will be a decrease in internal jugular venous flow in the park bench position when compared to the supine position. There will also be a change in blood flow between the right and left internal jugular veins in the park bench position. In particular, there will be a greater reduction of flow on the dependent side. However, the internal jugular venous flow will be the same in both the prone and supine positions.

Conditions

  • Jugular Venous Flow

Interventions

OTHER

comparison of different neurosurgical position

in 2 of 3 positions (supine, plus either prone or park bench) with both left and right internal jugular vein cross-sectional area of vein, doppler velocity, internal jugular venous flow, position of internal jugular vein in relation to carotid artery (All measured with the use of ultrasound)
