Utilizing an infusion pump, solutions are typically delivered into the bloodstream at a preset and fixed rate. Intravenous (IV) therapy is one of the most common treatment modalities in hospitals worldwide. The multiplex algorithm allows for more efficient use of IV lumens compared to the conventional multi-infusion strategy. The multiplex algorithm addresses a major issue that occurs in ICUs, operating rooms, oncology wards, and many other hospital departments where several incompatible drugs are infused through a restricted number of lumens. In 27% of all drug combinations, and 61% of the unique combinations the multiplex algorithm required fewer lumens ( p 3 lm, versus 12% using the conventional procedure. The mean ± SD number of simultaneous IV solutions was 2.8 ± 1.6. We used data from 175,993 ICU drug combinations, with 2251 unique combinations received by 2715 consecutive ICU patients. The number of lumens required by the conventional procedure (L CONV) and multiplex algorithm (L MX) were compared. The conventional scheduling procedure executed by ICU nurses was used for comparison. MethodsĪ multiplex algorithm was developed that schedules the alternating IV administration of multiple incompatible IV solutions through a single lumen, taking compatibility-related, pharmacokinetic and pharmacodynamic constraints of the relevant drugs into account. Our objective was to develop and evaluate an algorithm designed to reduce the number of intravenous lumens required in multi-infusion settings by multiplexing the administration of various parenteral drugs and solutions. When the number of available lumens is too low to facilitate the safe administration of these solutions, additional (peripheral) IV catheters are often required, causing physical discomfort and increasing the risk for catheter related complications. As drugs or their solvents are frequently chemically incompatible, many solutions must be administered through separate lumens. They are good at allowing administration of home antibiotics or nutrition by vein (parenteral nutrition) because of the stability of the access combined with safety.Multi-drug intravenous (IV) therapy is one of the most common medical procedures used in intensive care units (ICUs), operating rooms, oncology wards and many other hospital departments worldwide. PICC lines should be cleansed and dressed. The initial IV is then split apart leaving the PICC line alone remaining in the vein. The PICC catheter is then placed through the IV which is already in the vein and advanced until the tip is near the heart. The PICC line is trimmed to a length that will allow the tip to lie near, but not in the heart. A special plastic IV catheter, which can be split apart and which is large enough to admit the PICC line itself, is placed into a vein. PICC lines commonly are available in sizes from 2 French to 7 French (3 French = 1 mm). I think some PICC catheters are cut to length which is why they must be measured on removal.I am familiar with the broviac I am confused by the way you have written some of your questions so hope the above helps a bit. Can't tell you the amount of times I've seen peopel inject into a PICC without swabbing it first with alcohol. Maintain strict cleanliness with PICC lines as the patient can pick up infections very easily from dirty hands and unsterile techniques. What do you mean all meds come out the tip of the PICC? I for one am a bit confused by your questions. PICCs can be used for nutritional reasons too and are very versatile. These can be labelled, but usually aren't. Red could be to draw blood, blue for IV medications, another port, ie: white, could be used for chemotherapy. They can thread PICCs thru any large vein if necessary though.Īll PICC lines I have used have multiple ports that are usually coloured. The PICC line needs to stay intact as medications go right into the patients superior vena cava, to their heart & circulatory system. I don't know why u think we would need to cut the tip or the port? What rationale did you have in mind for that - just interested in your thinking process. People from other countries may have different ways of saying things too. OP you are shooting yourself in the foot as we can't understand what your abbreviations are and therefore you may lose out on valuable answers. What is an EHR? What does TLC stand for? Sorry can people PLEASE put the full word at first, then the abbreviation in brackets.
