TruVascular Access - Ultrasound-Guided Vascular Access Study

Brief Summary

TruVascular Access - TVA-2026 is a prospective, randomized clinical study evaluating whether ultrasound-guided peripheral vascular access improves first-attempt cannulation success compared with conventional landmark, visualization, and palpation-guided techniques in adults who require clinically indicated peripheral venous access. Participants will be assigned to either an ultrasound-guided vascular-access workflow or a standard vascular-access workflow. The primary outcome is successful placement of a functional peripheral vascular catheter on the first cannulation attempt. Secondary outcomes include the total number of cannulation attempts, time to successful vascular access, successful access within two attempts, need for rescue or escalation to another vascular-access method, patient-reported procedural pain, access-related complications, catheter function, and operator-reported procedural difficulty. The study will also collect information about participant characteristics, difficult intravenous access features, vascular anatomy, catheter characteristics, operator experience, and other procedural factors that may influence successful vascular access. These data may be used to identify patient and procedural characteristics associated with first-attempt success and to improve future vascular-access workflows. Participant safety will take priority over study assignment. If the assigned technique is unsuccessful or clinically inappropriate, the treating clinician may use an alternative or rescue vascular-access method according to applicable clinical practice and study procedures.
