For both of them different flow rates, flushing volumes, and times were tested. <\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p> The PU catheter lumens were filled with a mixture of fibronectin and bovine albumin to simulate physiologic protein depot. Flushing was performed with normal saline. An adapted pump controlled the flow rates. Efficacy was measured by the amount of albumin recovered from the lumen of the tested devices. Flow rate, volumes, and times tested were based upon values reported and\/or measured in nursing practices. We compared: (A) single 10 mL bolus and 6 flushing times, (B) continuous infusion of 500 mL in 24 hours, (C) 10 successive boluses 1 mL flushed in 0.5 s each and 6 different time intervals between each bolus. Statistics were performed using the Mann and Whitney U test. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p> In group A, the maximum percentage of recovered protein (79.1% was achieved with the 10 mL bolus flushed in 2.5. In group B, 77% of protein was recovered at 24h. In group C: maximum efficacy (90 +\/- 3%) was obtained when the time interval between 2 boluses was 0.4 s. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p> We conclude that hydrodynamics has a determinant effect on the efficacy and that the adjunction of an intermittent component in the flow increases it. Flow type and the time interval between 2 boluses are the 2 critical variables. <\/jats:p><\/jats:sec>","DOI":"10.5301\/jva.2011.8487","type":"journal-article","created":{"date-parts":[[2011,7,11]],"date-time":"2011-07-11T14:17:14Z","timestamp":1310393834000},"page":"75-78","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":48,"title":["Flushing of Intravascular Access Devices (IVADs) - Efficacy of Pulsed and Continuous Infusions"],"prefix":"10.1177","volume":"13","author":[{"given":"G\u00e9rard","family":"Guiffant","sequence":"first","affiliation":[{"name":"MSC-UMR 7057, Universit\u00e9 Paris Diderot, Paris - France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean Jacques","family":"Durussel","sequence":"additional","affiliation":[{"name":"MSC-UMR 7057, Universit\u00e9 Paris Diderot, Paris - France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacques","family":"Merckx","sequence":"additional","affiliation":[{"name":"MSC-UMR 7057, Universit\u00e9 Paris Diderot, Paris - France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrice","family":"Flaud","sequence":"additional","affiliation":[{"name":"MSC-UMR 7057, Universit\u00e9 Paris Diderot, Paris - France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean Pierre","family":"Vigier","sequence":"additional","affiliation":[{"name":"MSC-UMR 7057, Universit\u00e9 Paris Diderot, Paris - France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrice","family":"Mousset","sequence":"additional","affiliation":[{"name":"Becton Dickinson, Le Pont-De-Claix Cedex - France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2011,11,7]]},"reference":[{"key":"bibr1-JVA.2011.8487","doi-asserted-by":"publisher","DOI":"10.1097\/00152193-200030100-00037"},{"key":"bibr2-JVA.2011.8487","doi-asserted-by":"publisher","DOI":"10.1016\/0927-7765(94)80037-5"},{"key":"bibr3-JVA.2011.8487","doi-asserted-by":"publisher","DOI":"10.1097\/00152193-200301000-00018"},{"key":"bibr4-JVA.2011.8487","first-page":"147","volume":"26","author":"Vigier J.P.","year":"2005","journal-title":"ITBMRBM"},{"key":"bibr5-JVA.2011.8487","doi-asserted-by":"publisher","DOI":"10.4037\/ajcc1993.2.1.3"},{"key":"bibr6-JVA.2011.8487","first-page":"1572","volume":"51","author":"American Society of Hospital Pharmacists","year":"1994","journal-title":"Am J Hosp Pharm."},{"key":"bibr7-JVA.2011.8487","unstructured":"Mc EvoyG.K.
