RESUMEN
We investigated the stability of thyroid hormones during a mode of continuous drug infusion via polypropylene tubing using the same conditions that would be applied to treating patients in a hospital setting. The diluted thyroid hormones were prepared using aseptic technique, stored at 2-8°C (36-46°F) and tested within 24 h of preparation for stability and percent recovery from within plastic tubing. Experiments were done in duplicate with triplicate sets of readings for each assay point. Only T(4) prepared with 5% dextrose water (D5W) containing 1 mg/mL albumin remained constant, stable, predictable and accurate over time under various conditions. Other methods of preparation lost drug by adhering to the plastic containers and tubing by as much as 40% of starting concentration. T(3) recovery in the presence of 1 mg/mL of albumin was 107±2% (mean±standard error of the mean) of anticipated drug concentrations. We conclude from this series of experiments that to maintain an accurate and stable dosing of patients receiving intravenous thyroid hormones, 1 mg/mL of albumin must be added to the infusate to prevent lost on the plastic intravenous tubing.

PURPOSE/OBJECTIVES: To review the literature regarding the incidence, current practice, guideline recommendations, nursing management, and knowledge gaps relevant to vesicant extravasation. DATA SOURCES: Published research articles, books, case reports, and national guidelines. DATA SYNTHESIS: Vesicant extravasation is a relatively rare but significant complication of chemotherapy administration. Extravasation may have a range of consequences that can cause serious physical and quality-of-life effects. Knowledge of risk factors and preventive measures can reduce patient risk. Data-based and empirical management strategies such as immediate local measures (agent withdrawal, comfort measures, and medical interventions) may minimize risk for extravasation, as well as lead to timely recognition and management and decreased morbidity should extravasation occur. CONCLUSIONS: Vesicant extravasation and sequelae constitute a complex patient problem that clinicians should strive to prevent or to minimize injury should it occur. To this end, clinicians must demonstrate awareness of risks and use specialized knowledge while administering vesicant agents. IMPLICATIONS FOR NURSING: Only nurses knowledgeable about extravasation and skilled in associated techniques should assume responsibility for vesicant administration.

PURPOSE/OBJECTIVES: To review the literature, synthesize current recommendations, and discuss remaining controversies regarding vesicant extravasation management. DATA SOURCES: Published evidence-based reports, clinical articles, and anecdotal case reports about antineoplastic and nonantineoplastic vesicant agent management. DATA SYNTHESIS: Prevention of vesicant extravasation sequelae requires knowledge about vesicant extravasation manifestations and differentiation of vesicant extravasation from other local IV site reactions. When evidence is weak or missing, logical application of data-based or empirical management strategies is critical. Actions may include timely administration of subcutaneous or topical antidotes, comfort measures, and surgical interventions to minimize the extent of tissue damage and morbidity should extravasation occur. CONCLUSIONS: Vesicant extravasation and sequelae constitute a complex patient problem. Clinicians should strive to prevent extravasation or seek to minimize injury should it occur. To this end, clinicians must demonstrate awareness of its risks and use specialized knowledge when administering vesicant agents. IMPLICATIONS FOR NURSING: Nurses who administer vesicant agents should understand the nursing and collaborative actions that should be taken to minimize patient morbidity, pain, and disability.
