Evaluation of the Effect of Venous Diameter Measurement by Ultrasonography on Pain and Withdrawal Response

"Four poin scala 0=No Pain~1. mild~2. intermediate~3. severe"

"Withdrawal movements~1. no movement response~2. movement limited to the wrist~3. movement limited to the elbow/shoulder,~4. generalized movement response."

Hemodynamic data were recorded in the patients taken in the operation room. (T0). Hemodynamic values (T1) measured 1 minute after administration of intravenous propofol were recorded. Hemodynamic values (T2) measured 1 minute after administration of intravenous rocuronium were recorded. Hemodynamic values (T3) measured 1 minute after administration of endotracheal intubation were recorded.
