Study Notes
Intravenous Incompatibilities
- Intravenous (IV) incompatibilities refer to the potential for adverse reactions or undesirable effects when mixing different medications or solutions.
- Objectives include recognizing sterile product components (vehicles, solutes, containers), understanding their typical uses and limitations, and noting additives' purposes and container considerations.
- Various factors can impact compatibility, such as the types of chemical interactions, the drugs' properties, and the container or vehicle.
- Knowledge of high-risk drug-drug incompatibilities is crucial. These include substances needing careful considerations for diluent requirements, container types, filters, and storage conditions.
- Important aspects to consider include factors impacting compatibility like pH, solubility, concentration, complexation, temperature, vehicle characteristics, and sorption.
- Understanding diluent/vehicle incompatibilities for reconstituting powdered medications is important. Different diluents like sterile water for injection (SWFI) and bacteriostatic water for injection (BWFI), along with normal saline (NS) and dextrose solutions (D5W), have specific uses.
- Water containing diluents, such as SWFI and BWFI, have single-use and multi-dose options.
- Bacteriostatic diluents include preservatives, have inherent toxicity, and are not suitable for neonates or spinal/epidural administration.
- Crucial is knowing compatibilities of IV medications based on vehicles. Some drugs require specific vehicles (e.g., only saline or only dextrose).
- Considerations for other administration vehicles include non-aqueous solvents (oils) and emulsified oils (soybean, safflower), as well as water-miscible cosolvents.
- Sterile water for injection (SWFI) packaged for inhalation use is not for injection.
- Common issues with PVC containers include leaching of plasticizers like DEHP, drug absorption, and drug adsorption.
- Alternative containers like glass, polyolefin, and polypropylene can be used to minimize these issues.
- Drug-drug incompatibilities frequently arise in Y-site administration. Additive incompatibility is also a significant concern due to prolonged contact time when drugs are mixed.
- High-risk incompatibilities warrant cautious consideration and avoidance in certain cases (e.g., ceftriaxone and calcium-containing solutions).
- Several resources and guidelines can assist with checking for incompatibilities. These involve specific references such as Trissel's Tables and databases like Lexicomp and King's Guide.
- These resources address Y-site, solution, admixture, and syringe compatibility, offering important interpretations (compatible, incompatible, conflicting).
- Knowledge and adherence to these guidelines are necessary to prevent potential complications during IV drug administration.
- Additives, such as preservatives, pH buffers, antioxidants, chelating agents, tonicity agents, and solubilizers, must be used carefully to maintain sterility, physical stability, chemical stability, and efficacy.
- The storage and administration of drugs should include specific temperature requirements and protection from light, as needed to minimize undesired chemical changes and microbial growth.
- In-line filters are necessary for drugs prone to particulate, precipitate, crystal, contaminant, or entrapped air formation. Certain drugs require filter administration to maintain drug integrity and minimize adverse effects.
