The ability of a needle guide to prevent a posterior vein wall injury which may secondarily induce lethal complications, is unknown. Previous studies showed that a shallow angle of approach may reduce the incidence of posterior wall injuries. We developed a novel needle guide with a shallow angle of approach for ultrasound-guided venous catheterization and examined whether this needle guide reduces the incidence of posterior wall injuries compared to a conventional needle guide and free-hand placement in a simulated vein.<h4>Methods</h4>This study was a randomized crossover-controlled trial. The primary outcome was the rate of posterior vein wall injuries. Participants had a didactic lecture about three ultrasound-guided techniques using the short-axis out-of-plane approach, including free-hand (P-free), a commercial needle guide (P-com), and a novel needle guide (P-sha). The view inside a simulated vein was recorded during venipuncture.<h4>Results</h4>Thirty-five residents participated in this study. Posterior vein wall injuries occurred in 66% using P-free, 60% using P-com, and 0% using P-sha (p< 0.01). There was no significant difference in the incidence of posterior vein wall injuries between P-free and P-com.<h4>Conclusions</h4>Use of a shallow angle of approach needle guide resulted in a lower rate of posterior vein injuries during venipuncture of a simulated vein compared with other techniques using a steeper angle techniques."],"journal":["PloS one"],"pagination":["e0235519"],"full_dataset_link":["https://www.ebi.ac.uk/biostudies/studies/S-EPMC7326219"],"repository":["biostudies-literature"],"pubmed_title":["Shallow-angle needle guide for ultrasound-guided internal jugular venous catheterization: A randomized controlled crossover simulation study (CONSORT)."],"pmcid":["PMC7326219"],"pubmed_authors":["Tokumine J","Lefor AK","Yorozu T","Watanabe K"],"additional_accession":[]},"is_claimable":false,"name":"Shallow-angle needle guide for ultrasound-guided internal jugular venous catheterization: A randomized controlled crossover simulation study (CONSORT).","description":"<h4>Background</h4>Needle guides for ultrasound-guided internal jugular venous catheterization facilitate successful cannulation.
