When should the nurse change the IV site?
Thank you to our sponsors Show AboutKidsHealth is proud to partner with the following sponsors as they support our mission to improve the health and wellbeing of children in Canada and around the world by making accessible health care information available via the internet. Our SponsorsFigure 8.4 IV Primary and secondary tubing set up IV solution bags should have the date, time, and initials of the health care provider marked on them to be valid. Add-on devices (e.g., extension tubing or dead-enders) should be changed every 96 hours, if contaminated when administration set is replaced, or as per agency policy. Intravenous solution and IV tubing should be changed if:
Primary and secondary administration sets (see Figure 8.4) should be changed regularly to minimize risk and prevent infection (CDC, 2011; Fraser Health Authority, 2014). Change IV tubing according to agency policy. Table 8.5 lists the frequency of IV tubing change. Table 8.5 Frequency of IV Tubing Changes
Infusing IV Fluids by Gravity or an Electronic Infusion Pump (EID)To ensure therapeutic effectiveness of IV fluids, a constant, even flow is necessary to prevent complications from too much or too little fluid. A physician must order a rate of infusion for IV fluids or for medications. The rate of infusion for medications (given via a secondary or primary infusion) can be found in the Parenteral Drug Therapy Manual (PDTM). If an order for IV fluids is “to keep vein open” (TKVO), the minimum flow rate is 20 to 50 ml per hour, or according to physician’s orders (Fraser Heath Authority, 2014). A health care provider is responsible for regulating and monitoring the amount of IV fluids being infused. IV fluid rates are regulated in one of two ways:
An IV pump must be used for:
To calculate the drops per minute for an infusion by gravity, follow the steps in Table 8.6. Table 8.6 Calculating the Drops per Minute (gtts/min) for an Infusion by Gravity
Take the IV calculations quiz for more practice with IV fluid dose calculation. When an infusion is by gravity, there are several factors that may alter the flow/infusion rate (Fulcher & Frazier, 2007). In addition to regulating the flow rate, assess the IV system to ensure these factors are not increasing or decreasing the flow of the IV solution. These factors are listed in Table 8.7.
Assessing an IV SystemAll patients with IV fluid therapy (PIV and CVC) are at risk for developing IV-related complications. The assessment of an IV system (including the IV site, tubing, rate, and solution) (see Figure 8.6) often depends on what is being infused, the patient’s age and medical condition, type of IV therapy (PIV or CVC), and agency policy. Generally, an IV system should be assessed as described in Checklist 65. Figure 8.6 Assess IV site prior to use Checklist 65: Assessing an IV System
When should an IV site be changed?The US Centers for Disease Control guidelines recommend replacement of peripheral intravenous (IV) catheters no more frequently than every 72-96 hours - ie every 3-4 days. Routine replacement is thought to reduce the risk of phlebitis and bloodstream infection.
How often should a nurse assess an IV site?IV systems must be assessed every 1 to 2 hours or more frequently if required. An IV system should be assessed at the beginning of a shift, at the end of a shift, if the electronic infusion device alarms or sounds, or if a patient complains of pain, tenderness, or discomfort at the IV insertion site.
How long can an IV site be used for?Many hospitals have protocols that require replacement of IV catheters every 72 to 96 hours, regardless of clinical indication.
What are the nursing responsibilities for IV therapy?The nurse's responsibilities in managing IV therapy include the following:. assessing an IV site.. priming and hanging a primary IV bag.. preparing and hanging a secondary IV bag.. calculating IV rates.. monitoring the effectiveness of IV therapy.. discontinuing a peripheral IV.. |
