The objective of this study is to evaluate maneuvers designed to increase basilic vein size which could be used to facilitate ultrasound-guided peripheral intravenous access USGPIV in the Emergency Department ED setting. Methods This was a prospective non-randomized trial. Healthy volunteers aged 18-65 were enrolled. Basilic veins were identified and the cross-sectional area measured sonographically. Following baseline measurement the following maneuvers were performed application of a tourniquet inflation of a blood pressure BP cuff application of a tourniquet with the arm lowered and BP cuff inflation with the arm lowered. Following each maneuver there was 30 s of recovery time and a baseline measurement was repeated to ensure that the vein had returned to baseline. Change in basilic vein size was modeled using mixed model analysis with a Tukey correction for multiple comparisons to determine if significant differences existed between different maneuvers. Results Over the 5-month study period 96 basilic veins were assessed from 52 volunteers. All of the maneuvers resulted in a statistically significant increase in basilic vein size from baseline p . BP cuff inflation had the greatest increase in vein size from baseline 17 mm 95 CI . BP cuff inflation statistically significantly increased vein size compared to tourniquet placement by 3 mm 95 CI . Conclusions The largest increase in .
