- Registration Number
- NCT03841864
- Lead Sponsor
- Cedars-Sinai Medical Center
- Brief Summary
Hypothesis The initial use of ultrasound guidance when indicated for difficult peripheral IV access will reduce the number of attempts required to achieve successful peripheral IV insertion and improve patient care and satisfaction.
- Detailed Description
Study objective The purpose of this research study is to compare 2 established peripheral IV insertion techniques (traditional vs ultrasound guided) in order to develop an algorithmic approach to peripheral IV insertion. Patient characteristics, medical history and co-morbidities, in addition to a pre-insertion physical exam vein assessment, will allow for the introduction of a vein classification system and a difficult IV insertion algorithm. Selecting the optimal modality for initial IV insertion will decrease the total number of attempts, facilitate appropriate gauge and location of IV insertion, avoid central line placement, decrease IV insertion pain scores and improve patient satisfaction. Currently, ultrasound guided peripheral IV insertion is performed by the IV team at Cedars-Sinai Medical Center or a trained anesthesia provider as a rescue technique after multiple failed attempts by traditional technique. Secondary to the constraints of both trained providers and equipment resources, the cohort of difficult IV insertion patients are subjected to multiple traditional IV insertion attempts prior to escalation to ultrasound guidance and occasionally, unnecessary central line placements indicated by only poor intravenous access.
Primary end point: Grade 2A vein classification cohort 2nd IV insertion attempt success rate comparison of traditional vs ultrasound guided technique, IV insertion pain scores, Patient satisfaction Secondary end points: Grade 2B and grade 3 vein classification ultrasound guided IV insertion success rate. Grade 1 and 2a vein classification 1st attempt IV insertion success rate. Grade 1 visualization 2nd attempt IV insertion success rate comparison of traditional vs ultrasound guided technique. Difficult IV insertion risk factors and associations, IV gauge and location, central line placement because of inadequate peripheral IV access

Group Intervention Description Grade 3 Vein Visualization IV placement using ultrasound guidance vs traditional method No vein visualization. Initial IV placement attempt will be ultrasound guided Grade 2b Vein Visualization IV placement using ultrasound guidance vs traditional method Only faint vein shadow appearance described as poor visualization. Initial IV placement attempt will be ultrasound guided Grade 1 Vein Visualization IV placement using ultrasound guidance vs traditional method Visual vein classification grade described as excellent Visualization. Objective vein criteria to be included in this group are vein raised above skin and wider than 1mm. Initial IV placement will be traditional attempt but subsequent attempts will be provider discretion for traditional vs ultrasound guided placement Grade 2A Vein Visualization IV placement using ultrasound guidance vs traditional method Veins that don't fit grade 1 or 2b classification (see respective group descriptions). This groups visual vein classification is described as fair visualization. Initial IV placement will be traditional attempt but subsequent attempts will be provider discretion for traditional vs ultrasound guided placement
- Primary Outcome Measures
Name Time Method Grade 1 and Grade 2A vein classification cohort 2nd IV insertion attempt success rate comparison of traditional vs ultrasound guided technique 9 months after patient recruitment begins IV insertion success rate comparison on the second IV insertion attempt (after after 1x unsuccessful IV insertion using traditional technique) between traditional technique versus ultrasound guidance for grade 1 and 2a visual vein classification grades. For an 80% powered study to detect a 30% difference in success rate, an N of 50 is required in each group. Outcome will be successful vs unsuccessful IV insertion
- Secondary Outcome Measures
Name Time Method Grade 2B and Grade 3 vein classification IV placement success rate 9 months after patient recruitment begins Ultrasound IV insertion success rate for grade 2B and grade 3 using ultrasound
