Extravasation Management of Nonchemotherapeutic Medications

Extravasation of Non-Cytotoxic Drugs in Older People

Objective To describe the risk factors of extravasation, its impact on the pharmacokinetics of non-cytotoxic drugs, and management of extravasation in older individuals. Extravasation occurs when vesicants leak from blood vessels into surrounding tissue causing severe injury such as tissue necrosis while infiltration is caused by leakage of an irritant that causes injury but does not lead to tissue necrosis. Extravasation occurs in approximately 0.01% to 6% of patients, particularly with cytotoxic agents. However, there is limited documentation about extravasation of non-cytotoxic agents, particularly in older people. Data Sources A literature search of Pubmed and Medline was performed using the following search items: "extravasation," "infiltration," "elderly," and "non-cytotoxic drugs," as well as a combination of these terms. Conclusion It is important to recognize, identify, and manage extravasation early since it can have deleterious consequences for older people. It is more important to prevent extravasation than manage it using standardized evidence-based protocols, and this can be implemented in the nursing facility and acute care setting.

Nurses' knowledge and experience related to short peripheral venous catheter extravasation

BACKGROUND

The majority of hospitalized patients receive a Peripheral Venous Catheter (PVC) in the course of their treatment. Extravasation injury is a serious complication of intravenous treatment.

OBJECTIVE

This cross-sectional survey designed study aims to investigate nurses' knowledge and experience related to short peripheral venous catheter extravasation.

METHOD

The study sample included 145 nurses working in a university hospital in the west of Turkey. A questionnaire developed in accordance with the literature was used for data collection. The data were assessed by frequency and proportions.

RESULTS

Of the nurses included in this study, 26.2% reported they had experienced extravasation injury in a patient; 74.5% said they had received no instruction in the management of extravasation during their in-service training program; and 85.5% stated they did not keep a record of extravasation. 89.7% of the nurses reported infused medications as a cause of extravasation, and 81.4% reported catheter sites as a cause. Among the medications reported by the nurses as causing extravasation: 89.7% reported contrast agents; 84.8% TPN solutions; 71.0% cytotoxic agents; and 65.1% mannitol. The symptoms of extravasation reported by nurses included: swelling (97.9%), redness (97.2%), pain (92.4%), rise in temperature (65.5%), and ulceration (60.0%). In responding to the occurrence of extravasation, interventions reported by the nurses included: stopping the flow of fluid (98.6%), elevation (89.7%), cold application (76.6%), and aspiration of drug (40.7%).

CONCLUSION

Based on these results, it is recommended that guidelines are developed for the management of extravasation, that periodic in-service training programs are provided and that observational studies are carried out into the administration of vesicant drugs.

Management of noncytotoxic extravasation injuries: A focused update on medications, treatment strategies, and peripheral administration of vasopressors and hypertonic saline

Extravasation is the leakage of intravenous solutions into surrounding tissues, which can be influenced by drug properties, infusion techniques, and patient-related risk factors. Although peripheral administration of vesicants may increase the risk of extravasation injuries, the time and resources required for central venous catheter placement may delay administration of time-sensitive therapies. Recent literature gathered from the growing use of peripheral vasopressors and hypertonic sodium suggests low risk of harm for initiating these emergent therapies peripherally, which may prevent delays and improve patient outcomes. Physiochemical causes of tissue injury include vasoconstriction, pH-mediated, osmolar-mediated, and cytotoxic mechanisms of extravasation injuries. Acidic agents, such as promethazine, amiodarone, and vancomycin, may cause edema, sloughing, and necrosis secondary to cellular desiccation. Alternatively, basic agents, such as phenytoin and acyclovir, may be more caustic due to deeper tissue penetration of the dissociated hydroxide ions. Osmotically active agents cause cellular damage as a result of osmotic shifts across cellular membranes in addition to agent-specific toxicities, such as calcium-induced vasoconstriction and calcifications or arginine-induced leakage of potassium causing apoptosis. A new category has been proposed to identify absorption-refractory mechanisms of injury in which agents such as propofol and lipids may persist in the extravasated space and cause necrosis or compartment syndrome. Pharmacological antidotes may be useful in select extravasations but requires prompt recognition and frequently complex administration strategies. Historically, intradermal phentolamine has been the preferred agent for vasopressor extravasations, but frequent supply shortages have led to the emergence of terbutaline, a β2 -agonist, as an acceptable alternative treatment option. For hyperosmolar and pH-related mechanisms of injuries, hyaluronidase is most commonly used to facilitate absorption and dispersion of injected agents. However, extravasation management is largely supportive and requires a protocolized multidisciplinary approach for early detection, treatment, and timely surgical referral when required to minimize adverse events.

Elaboration and validation of an algorithm for treating peripheral intravenous infiltration and extravasation in children

OBJECTIVE

to elaborate and validate the content and appearance of an algorithm for treating infiltration and extravasation of non-chemotherapy drugs and solutions administered to children.

METHOD

a methodological study of the technology formulation and validation type. To elaborate the algorithm, a bibliographic review was carried out to list the scientific evidence on the treatment of infiltration and extravasation. Content and appearance validation was in charge of 14 specialists in pediatric nursing, using the Delphi technique, adopting a value equal to or greater than 0.80 as Content Validation Index.

RESULTS

the algorithm was validated in the third evaluation by the judges, reaching a Global Content Validation Index of 0.99, being composed by the perception of the occurrence of the complication; discontinuation of intravenous therapy infusion; verification of signs and symptoms; measurement of edema; application of an infiltration and extravasation assessment scale and conduits to be used according to the characteristics of the fluid administered and the type of complication.

CONCLUSION

the algorithm was validated and can be used in a practical and objective way by health professionals, in order to promote safety in the care of hospitalized children, with regard to reducing harms caused by infiltration and extravasation.

Recommendations for Management of Noncytotoxic Vesicant Extravasations

To prepare clinicians to treat extravasation of noncytotoxic vesicants with antidotes and thermal compresses, a literature review was performed to identify noncytotoxic vesicants and to create evidence and consensus-based recommendations. The stage of injury and vesicant's mechanism of tissue injury dictate treatment. For a vasopressor extravasation, warm compresses and administration of a vasodilator are recommended. For osmolarity, pH, absorption refractory, and cytotoxic concentration-dependent vesicants, warm compresses and administration of hyaluronidase are recommended. Compared with potentially catastrophic costs of undertreatment, the cost of overtreatment is minimal.

An update on extravasation: basic knowledge for clinical pharmacists

Extravasation is the leakage of intravenously administered solution into surrounding tissues, which can cause serious damage to the patient. The impact of extravasation is mostly determined by the localisation and volume of extravasation, but the physicochemical properties of the drugs are also important. In this paper a stepwise approach to managing an extravasation is described, with recommendations on the role of the pharmacist. Information on osmolality, pH, pKa and the buffering capacity of drugs is given in relation to extravasation, which is summarised in a practical crash card that can be used in clinical practice.

Accepted but Unacceptable: Peripheral IV Catheter Failure

Peripheral intravenous (IV) catheter insertion, the most common invasive hospital procedure performed worldwide, is associated with a variety of complications and an unacceptably high overall failure rate of 35% to 50% in even the best of hands. Catheter failure is costly to patients, caregivers, and the health care system. Although advances have been made, analysis of the mechanisms underlying the persistent high rate of peripheral IV failure reveals opportunities for improvement.

A Case of Metronidazole Injection Infiltration Without Sequelae

Purpose: This report describes a case of metronidazole injection infiltration which contrasts the sole other case report in the literature at this time, as the patient described herein experienced mild signs and symptoms with prompt resolution and no significant sequelae. Summary: The patient experienced metronidazole injection infiltration during administration open to gravity via an 18-gauge peripheral catheter in the left brachial vein. The site was examined at bedside within approximately 30 minutes of the incident and was noted to be slightly edematous, erythemic, and painful in terms of a 5.5 × 6.6-cm area. No blanching, blister formation, induration, skin discoloration, or diminished capillary refill were observed. The event was conservatively managed in the form of catheter discontinuation and marking of the affected area with a patient skin marker, as hyaluronidase was not administered due to a product osmolarity of ~314 mOsM/L and pH of 5.8. A bedside evaluation the next morning revealed full resolution of the previously described symptoms. The patient was discharged from the facility 11 days later without further complications from the infiltration event. Conclusion: We describe a case of metronidazole injection infiltration which did not require pharmacologic or nonpharmacologic interventions and resulted in complete resolution. This case supplements the current literature by contrasting the sole other case report which resulted in profound necrosis near the intravenous access site. This case suggests metronidazole infiltrations may not require clinician alarm or treatment if events occur under circumstances similar to that which is presented.

Management of Intravenous Contrast Extravasations with Ultrasonography: A Case Report

Extravasation of ionic and nonionic contrast materials is a well-recognized complication of contrast-enhanced imaging studies. Complications vary from minimal swelling to severe skin and subcutaneous ulceration, necrosis, and compartment syndrome. We report a case of Omnipaque (iohexol) extravasation in a 50-year-old man with erythema, blistering, and compartment syndrome who was treated medically but was not cured. Using gray scale ultrasonography, we determined the characteristics of the lesion, its distance from the skin, and its proximity to the vessels. We then determined the depth of the lesion, and then inserted the tip of the needle into the lesion. We also used ultrasonography in locations where extravasation was near an artery. After aspiration, the diameter of the lesion decreased significantly. The patient was cured by ultrasonography-guided aspiration from the extravasated site.
