Brief Summary

This is a randomized controlled trial comparing the success of US guided peripheral IV placement between single vs dual-operator technique among a convenience sample of patients with moderate or difficult vascular access in a tertiary care Emergency Department.

Detailed Description

Gaining intravenous (IV) access is a common and important procedure in the emergency department (ED). IV access is needed to deliver drugs, enable fluid resuscitation and sample blood, and delays in gaining access can lead to patient harm. Ultrasound (US) is a commonly used tool in the ED, and the utility of ultrasound in the placement of IVs in patients with difficult access has been well described. This study aims to further guide the use of this evidence based tool by ED Registered Nurses. The focus will be comparing single-operator technique, in which the same provider manipulates the ultrasound probe while simultaneously placing the IV, to a dual-operator technique whereby a second provider manipulates the probe. Any measured advantage has implications in guiding education and practice, as well as informing future ED policy.

Conditions

Patients With Difficult Vascular Access.

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Single-Operator

For the 'Single Operator Ultrasound Guided IV placement' arm the RN operator will use the ultrasound probe to identify the target vein, and continue to hold and adjust the probe while placing the IV.

Group Type: EXPERIMENTAL

Single Operator Ultrasound Guided IV placement

Intervention Type: PROCEDURE

Single operator holds ultrasound probe and places IV.

Dual-Operator

For the 'Dual Operator Ultrasound Guided IV placement' arm the RN operator will use the US to identify the target vein, at which time the study coordinator will hold the ultrasound probe in position. The RN operator will then place the IV.

Group Type: EXPERIMENTAL

Dual Operator Ultrasound Guided IV placement

Intervention Type: PROCEDURE

Second operator holds ultrasound probe.

Interventions

Dual Operator Ultrasound Guided IV placement

Second operator holds ultrasound probe.

Intervention Type: PROCEDURE

Single Operator Ultrasound Guided IV placement

Single operator holds ultrasound probe and places IV.

Intervention Type: PROCEDURE

Eligibility Criteria

Inclusion Criteria

• Adult (18 years and older) patients predicted to require intravenous cannulas and identified at triage as having moderate or difficult access based on the following criteria:

Moderate: peripheral vein is visible or palpable but difficulty is expected based on patient characteristics both clinical and historical.

Difficult: No peripheral veins visible or palpable, or two failed attempts by traditional landmarking (LM).

• Minimum Eligible Age: 18 Years
• Eligible Sex: ALL
• Accepts Healthy Volunteers: No
