Accidental Extravasation of Mitomycin C into the Subcutaneous Tissue.

Introduction: Mitomycin C (MMC) is a common chemotherapeutic agent used to treat a variety of solid tumors. Cutaneous adverse events are rare, but MMC is a known vesicant reported to cause tissue necrosis and sloughing, erythema, and ulceration if incorrectly infused into the subcutaneous tissue. Definitive treatment of extravasation injuries due to MMC depends on the severity of the cutaneous manifestation, which includes stopping the infusion, removing the catheter, or possible debridement. Case Presentation: We present the case of a 70-year-old female with extensive soft-tissue injury secondary to extravasation of MMC that required hospital admission and surgical intervention to remove the implantable venous access device. Conclusion: Extravasation injuries caused by vesicant drugs, such as MMC, often present as local skin irritation and inflammation. MMC extravasation may present a wide range of skin and soft tissue manifestations, ranging from erythema to ulcerations to necrosis. This rare but potentially detrimental complication of chemotherapy infusions should be recognized in cancer patients.

Perforated intravenous catheter design is acceptable for the administration of contrast-enhanced computed tomography administration in cancer patients: Results of a pilot randomised controlled trial.

BACKGROUND: Optimising first time success of peripheral intravenous catheter (PIVC) insertion and reducing intravenous (IV) complications in cancer patients undergoing contrast-enhanced computed tomography (CT) is vital to ensure vascular access preservation and diagnostic accuracy. The aim of this study was to test the feasibility of a randomised controlled trial (RCT) evaluating a novel perforated PIVC compared to a standard PIVC. METHODS: A single centre, parallel-group, pilot RCT was conducted between March and May 2020. Adult participants diagnosed with cancer were randomised to a non-perforated PIVC (standard care) or a PIVC with a novel perforated design (intervention) for the administration of IV contrast. There were two primary outcomes: (1) feasibility of an adequately powered RCT with pre-established criteria; and (2) all-cause PIVC failure. Secondary outcomes included: first insertion success, modes of PIVC failure, dwell time, contrast injection parameters (volume and injection rate), contrast enhancement, radiographer satisfaction and adverse events. RESULTS: Feasibility outcomes were met, except for eligibility (⩾90%) and recruitment (⩾90%). In total, 166 participants were screened, 128 (77%) were eligible and of these 101/128 (79%) were randomised; 50 to standard care and 51 to intervention. First time insertion rate was 94% (47/50) in standard care and 90% (46/50) in intervention. The median dwell time was 37 minutes (interquartile range (IQR): 25-55) in standard care and 35 minutes (IQR: 25-60) in the intervention group. There was one PIVC failure, a contrast media extravasation, in the intervention group (1/51; 2%). The desired contrast injection rate was not achieved in 4/101 (4%) of participants; two from each group. Radiographers were satisfied with the contrast flow rate. CONCLUSIONS: This pilot RCT suggests perforated PIVCs provide expected flow rate, with no evidence of differences in contrast enhancement to non-perforated PIVCs. The feasibility of conducting a larger powered RCT was demonstrated.

Introduction: The use of antineoplastic chemotherapies acting at the cellular level with the aim of treating malignant neoplasms can lead to the emergence of dermatological toxicity caused by extravasation. This toxicity consists of tissue damage resulting from the infiltration, by intravenous route, of the chemotherapeutic agents to the surrounding tissues, requiring quick and effective professional action to avoid unfavorable outcomes for the patient. Objective: To understand the nurses' perception of care related to extravasation of antineoplastic drugs. Method: This is a descriptive-exploratory field study with a qualitative approach; it was carried out with fifteen nurses who work in the outpatient and adult oncology wards of a philanthropic hospital located in Recife/Pernambuco, Brazil. Data were collected between January and December 2020 through interviews and underwent thematic-category content analysis. Results: Two categories emerged: Preventive Care: from the identification of risk factors to the patient and health team education; and Direct Care: from the identification of the occurrence to the institutional management of the event. Conclusion: It was understood that the nurse's perception highlights the importance of care planning, including immediate intervention, event registration, and patient follow-up after extravasation, to perform specialized care and with greater safety.

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 ß2 -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.

Endometritis risk factors after arterial embolisation for postpartum haemorrhage.

Various complications of arterial embolisation (AE) for postpartum haemorrhage (PPH) are reported. Endometritis (EM) frequently causes abscesses, increasing hysterectomy risk. However, risk factors for EM after AE for PPH are unclear. We explored these risk factors. We included patients who underwent AE for PPH in our hospital from 2005 to 2020 and compared those who did (EM group) and did not develop EM after AE (non-EM group) in a case-control study. Twenty patients met the study criteria; eight patients (40%) had EM. There were no differences in risk factors between groups involved in infection, such as premature rupture of membranes. However, the contrast medium extravasation rate on computed tomography scans before the AE procedure was significantly higher in the EM group (p=.019) compared to the non-EM group. The greatest EM risk factor was contrast medium extravasation before AE for PPH, determined by classification and regression tree modelling (relative risk: 4.5).Impact StatementWhat is already known on this subject? Reportedly, the clinical success rate of arterial embolisation (AE) for critical haemorrhage in obstetrics is high, around 90%. However, information regarding AE complications is limited. Endometritis is one of these complications, which not only causes prolonged hospitalisation but may also require further treatment, such as hysterectomy. However, the incidence rate and risk factors for EM remain unknown.What do the results of this study add? In this study, 40.0% of patients developed EM after AE for PPH. Extravasation of contrast medium was the top risk factor (relative risk: 4.5 compared to those without EM, p=.019). The second-leading risk factor was a bleeding volume greater than 2500 mL (relative risk: 4.5 compared to those without EM, p=.019).What are the implications of these findings for future clinical practice and/or future research? We created an EM prediction model using extravasation and a bleeding volume greater than 2500 mL. The model was 87.5% sensitive and 66.7% specific. This prediction model allows for the early detection and treatment of EM by recognising high-risk patients and providing intensive postpartum management.

Simulation method based on PET image for tail vein extravasation correction / 中华核医学与分子影像杂志

Objective:To establish a method for correction of tail vein extravasation based on PET images and to improve the accuracy of SUV.Methods:The simulation method was established by phantom on Nano PET/CT and images were reconstructed by a three-dimensional ordered-subsets exception maximum algorithm. PET images were analyzed by using the Interview Fusion 1.0 software. The optimal scanning time and the ROI delineated method were found. The accuracy of the simulation method was verified by comparing the activity of simulation method with the mice tail activity measured by the dose calibrator directly on Kunming (KM) mouse ( n=11). Using the simulation method, the impact of extravasation on SUV was proved. Independent-sample t test was used to analyze data. Results:Ten minutes was selected as the optimal scanning time and SUV max 42% threshold was selected as the ROI delineated method. The specific correction formula was as follows: actual activity=image activity/(4.48× V+ 77.05)×100 (0.3 MBq/ml≤leakage concentration<6.5 MBq/ml); actual activity=image activity/(6.65× V+ 71.10)×100 (6.5 MBq/ml<leakage concentration≤14.8 MBq/ml). In the verification experiment, the difference rate between simulated and standard activity was (6.10±2.43)%. In actual operation verification, SUV was underestimated by (6.07±2.67)%. The corrected SUV (0.276±0.078) was not significantly different from the standard SUV (0.277±0.078; t=0.99, P=0.353), while the uncorrected SUV (0.264±0.078) was significantly lower than the standard SUV ( t=7.02, P<0.001). Conclusion:The correction calculation method based on PET images can realize the accurate correction of tail vein leakage activity and the SUV results of animal imaging.

A case report of furosemide extravasation in the hand: a rare cause of compartment syndrome.

In emergency departments, many drugs, fluids, and materials for medical examinations and treatment are typically administered to patients intravenously. One of the most common complications of the intravenous bolus or infusion of drugs is extravasation injuries. These injuries may cause certain morbidities for the patient, increase the cost of treatment, and prolong hospital stays. At the same time, these injuries also carry medicolegal risks for health personnel. Furosemide is a potent diuretic that is commonly used in emergency departments for volume overload conditions. To the best of our knowledge, there have been no cases reported in the literature of furosemide-induced extravasation injury with subsequent compartment syndrome that has required surgical intervention. Presented herein is the case of a 70-year-old female patient who was administered intravenous furosemide from the dorsum of the left hand and whose extravasation injury progressed to compartment syndrome requiring an emergency fasciotomy.

[Systematic action-Emergencies in systemic cancer therapy!] / Systematisches Handeln ­ Notfälle der medikamentösen Tumortherapie!

BACKGROUND: A multitude of treatment options for the systemic treatment of urologic cancer have become available in recent years. In addition to classical chemotherapy or androgen-deprivation therapy, other approaches like targeted therapies (e.g., tyrosine kinase inhibitors), checkpoint inhibitors, and new approaches like radioligand therapies are increasingly used. Whether treating their own patients or caring for patients who receive these compounds from other physicians in the field, urologists will inevitably be confronted with adverse events associated with these diverse therapies. This development will continue to grow as new compounds are continuously being registered and even new drug classes are being developed. Therefore, every urologist should know the basics regarding prophylaxis, control of adverse events, and especially management of emergency situations associated with systemic treatment in uro-oncology. OBJECTIVES: To provide an overview of typical emergency situations and their management in genitourinary cancers. METHODS: Summary of common uro-oncological emergency situations associated with systemic therapy. RESULTS: The urologist requires expert knowledge in the management of emergencies within systemic treatment of genitourinary cancers like neutropenic fever during chemotherapy, hand-foot syndrome with tyrosine kinase inhibitors, immune-related adverse events, but also of side effects occurring in patients treated by other physicians, e.g., during radioligand therapies administered by nuclear physicians. CONCLUSIONS: Basic knowledge on the typical side effects and emergencies that are associated with compounds used in the treatment of genitourinary cancers is essential. Continuous medical education to be able to handle the new developments in this rapidly evolving field is mandatory.

Management of Ketamine Extravasation in a Pediatric Patient During Procedural Sedation.

Ketamine is a commonly used intravenous and intramuscular medication for procedural sedation within pediatric emergency medicine. There is limited availability of data on the rate of absorption and use of subcutaneous ketamine administration. We describe the case of a 12-year-old male who was sedated after extravasation and subsequent absorption of ketamine 1 mg/kg from a peripheral intravenous line (PIV). Despite being an unintended route, absorption of subcutaneous ketamine resulted in satisfactory procedural sedation with no complications. Given limited data on subcutaneous ketamine pharmacokinetics, the aim of this case report is to present the observed absorption of subcutaneous ketamine due to extravasation of PIV during a pediatric procedural sedation.

CT-based radiomics for differentiating intracranial contrast extravasation from intraparenchymal haemorrhage after mechanical thrombectomy.

OBJECTIVE: To develop a nonenhanced CT-based radiomic signature for the differentiation of iodinated contrast extravasation from intraparenchymal haemorrhage (IPH) following mechanical thrombectomy. METHODS: Patients diagnosed with acute ischaemic stroke who underwent mechanical thrombectomy in 4 institutions from December 2017 to June 2020 were included in this retrospective study. The study population was divided into a training cohort and a validation cohort. The nonenhanced CT images taken after mechanical thrombectomy were used to extract radiomic features. The maximum relevance minimum redundancy (mRMR) algorithm was used to eliminate confounding variables. Afterwards, least absolute shrinkage and selection operator (LASSO) logistic regression was used to generate the radiomic signature. The diagnostic performance of the radiomic signature was evaluated by the area under the curve (AUC), accuracy, specificity, sensitivity, positive predictive value (PPV), and negative predictive value (NPV). RESULTS: A total of 166 intraparenchymal areas of hyperattenuation from 101 patients were used. The areas of hyperattenuation were randomly allocated to the training and validation cohorts at a ratio of 7:3. The AUC of the radiomic signature was 0.848 (95% confidence interval (CI) 0.780-0.917) in the training cohort and 0.826 (95% CI 0.705-0.948) in the validation cohort. The accuracy of the radiomic signature was 77.6%, with a sensitivity of 76.7%, a specificity of 78.9%, a PPV of 85.2%, and a NPV of 68.2% in the validation cohort. CONCLUSIONS: The radiomic signature constructed based on initial post-operative nonenhanced CT after mechanical thrombectomy can effectively differentiate IPH from iodinated contrast extravasation. KEY POINTS: • Radiomic features were extracted from intraparenchymal areas of hyperattenuation on initial post-operative CT scans after mechanical thrombectomy. • The nonenhanced CT-based radiomic signature can differentiate IPH from iodinated contrast extravasation early. • The radiomic signature may help prevent unnecessary rescanning after mechanical thrombectomy, especially in cases where contrast extravasation is highly suggestive.

Case Series of Neonatal Extravasation Injury: Importance of Early Identification and Management.

Extravasation injury is a common iatrogenic injury, especially in neonates. Intravenous access is essential in neonatal care, but neonatal extravasation injury is associated with severe morbidity. We present three cases of neonatal extravasation injuries with varying presentations, etiological agents, and timing of management. It shows that extravasation injuries treated with the saline flush-out technique and timely intervention have a superior outcome with almost immediate resolution and subsequent healing with no scars. This is in stark contrast with the lesions treated conservatively with dressings that took more time to heal. We are reminded to be vigilant with infusion therapies and the importance of early detection and prompt treatment in neonatal extravasation injuries.

Intravenous contrast medium extravasation: systematic review and updated ESUR Contrast Media Safety Committee Guidelines.

NEED FOR A REVIEW: Guidelines for management and prevention of contrast media extravasation have not been updated recently. In view of emerging research and changing working practices, this review aims to inform update on the current guidelines. AREAS COVERED: In this paper, we review the literature pertaining to the pathophysiology, diagnosis, risk factors and treatments of contrast media extravasation. A suggested protocol and guidelines are recommended based upon the available literature. KEY POINTS: • Risk of extravasation is dependent on scanning technique and patient risk factors. • Diagnosis is mostly clinical, and outcomes are mostly favourable. • Referral to surgery should be based on clinical severity rather than extravasated volume.

Abstract Objective: to investigate the effect of using different agents (topical hyaluronidase, photobiomodulation, and the association of photobiomodulation with topical hyaluronidase) in preventing the formation of lesions caused by doxorubicin extravasation, as well as in the reduction of lesions formed by extravasation of this drug. Method: a quasi-experimental study conducted with 60 Wistar rats, randomized into four groups with 15 animals each. Group 1 (Control); Group 2 (Hyaluronidase); Group 3 (Photobiomodulation); and Group 4 (Hyaluronidase + Photobiomodulation). A wound was induced by applying 1 mg of doxorubicin to the subcutaneous tissue of the back of the animals. The concentration of topical hyaluronidase was 65 turbidity units/g and the energy employed was 1 joule of 100 mW red laser per square centimeter. With macroscopic evaluation every two days for 28 days, the following variables were observed: skin integrity, presence of blisters, hyperemia, exudate, bleeding, edema, crust, peeling and granulation tissue. Results: the animals from the groups subjected to photobiomodulation obtained better results in the assessment of the following variables: bleeding, hyperemia, exudate, intact skin and edema. Conclusion: it was evidenced that the association of photobiomodulation with topical hyaluronidase was effective in reducing the local effects and assisted in the wound healing process, and that PBM alone was able to prevent appearance of lesions.

Objective: To reach at an expert consensus, using the Delphi method, forclassifying the tissue-damaging potential of antineoplastic drugs, in order tofacilitate the decision-making process in the event of extravasations.Method: The panel of expert evaluators was made up of seven pharmacists belonging to the working group on extravasations. Other memberserved as coordinator. The likelihood of tissue damage was reviewed on thebasis of eight reference documents. Four categories of drugs were established: vesicant (V); high risk irritant (HRI); low risk irritant (LRI) and non-irritant(NI). Two rounds of surveys were performed. The drugs with an agreementof less than 70% after the two rounds were discussed non-anonymously by thegroup. For each of the rounds the following was analysed: median ofthe degree of consensus and the interquartile range (IQR25-75), degreeof agreement by tissue damage category, and percentage of antineoplastics reaching a degree of consensus of over 85% and of 100%. Drugswhose classification differed in the various reference documents were assessed separately. SPSS v23.0 statistical software was used. (AU)

The effects of shoulder arthroscopy on ultrasound image quality of the interscalene brachial plexus: a pre-procedure vs post-procedure comparative study.

BACKGROUND: Fluid extravasation from the shoulder compartment and subsequent absorption into adjacent soft tissue is a well-documented phenomenon in arthroscopic shoulder surgery. We aimed to determine if a qualitative difference in ultrasound imaging of the interscalene brachial plexus exists in relation to the timing of performing an interscalene nerve block (preoperative or postoperative). METHODS: This single-center, prospective observational study compared pre- and postoperative interscalene brachial plexus ultrasound images of 29 patients undergoing shoulder arthroscopy using a pretest-posttest methodology where individual patients served as their own controls. Three fellowship-trained regional anesthesiologists evaluated image quality and confidence in performing a block for each ultrasound scan using a five-point Likert scale. The association of image quality with age, gender, BMI, duration of surgery, obstructive sleep apnea, and volume of arthroscopic irrigation fluid were analyzed as secondary outcomes. RESULTS: Aggregate preoperative mean scores in quality of ultrasound visualization were higher than postoperative scores (preoperative 4.5 vs postoperative 3.8; p < .001), as was confidence in performing blockade based upon the imaging (preoperative 4.8 vs postoperative 4.2; p < .001). Larger BMI negatively affected visualization of the brachial plexus in the preoperative period (p < 0.05 for both weight categories). Patients with intermediate-high risk or confirmed obstructive sleep apnea had lower aggregate postoperative mean scores compared to the low-risk group for both ultrasound visualization (3.4 vs 4.0; p < .05) and confidence in block performance (3.8 vs 4.4; p < .05). CONCLUSION: Due to the potential reduction of ultrasound visualization of the interscalene brachial plexus after shoulder arthroscopy, we advocate for a preoperative interscalene nerve block when feasible.

Safety and Efficacy of 23.4% Sodium Chloride Administered via Peripheral Venous Access for the Treatment of Cerebral Herniation and Intracranial Pressure Elevation.

BACKGROUND: Sodium chloride (NaCl) 23.4% solution has been shown to reduce intracranial pressure (ICP) and reverse transtentorial herniation. A limitation of 23.4% NaCl is its high osmolarity (8008 mOsm/l) and the concern for tissue injury or necrosis following extravasation when administered via peripheral venous access. The use of this agent is therefore often limited to central venous or intraosseous routes of administration. Our objective was to evaluate the safety and efficacy of administration of 23.4% NaCl via peripheral venous access compared with administration via central venous access. METHODS: We reviewed pharmacy records to identify all administrations of 23.4% NaCl at our institution between December 2017 and February 2020. Medical records were then reviewed to identify complications, such as extravasation, soft tissue injury or necrosis, hypotension (mean arterial pressure less than 65 mm Hg), pulmonary edema, hemolysis, and osmotic demyelination. We also compared the change in physiological variables, such as ICP, mean arterial pressure, cerebral perfusion pressure, and heart rate, as well as laboratory values, such as sodium, chloride, bicarbonate, creatinine, and hemoglobin, following administration of 23.4% NaCl via the peripheral and central venous routes. RESULTS: We identified 299 administrations of 23.4% NaCl (242 central and 57 peripheral) in 141 patients during the study period. There was no documented occurrence of soft tissue injury or necrosis in any patient. One patient developed hypotension following central administration. Among the 38 patients with ICP monitoring at the time of drug administration, there was no significant difference in median ICP reduction (- 13 mm Hg [central] vs. - 24 mm Hg [peripheral], p = 0.21) or cerebral perfusion pressure augmentation (16 mm Hg [central] vs. 15 mm Hg [peripheral], p = 0.87) based on route of administration. CONCLUSIONS: Peripheral venous administration of 23.4% NaCl is safe and achieves a reduction in ICP equivalent to that achieved by administration via central venous access.

Síndrome compartimental por extravasación de líquidos en paciente pediátrico, reporte de un caso y revisión de la literatura / Compartment Syndrome Due To Liquid Extravasation In A Pediatric Patient. Case Report And Bibliographic Review

El Síndrome Compartimental por Extravasación (SCE) es una patología poco frecuente, con una incidencia de 0,01-6,5%, 1.8-11% en niños. En niños pequeños la comunicación es difícil y aumenta el riego de desarrollo de SCE. Se presenta un caso de un masculino de 9 meses de edad, con Neumonía viral sobreinfectada que desencadena SCE; recibió descompresión compartimental del antebrazo y mano derecha; con desarrollo de secuelas leves. Aplicar tratamiento para lesión por extravasación no siempre es suficiente; existen complicaciones leves-moderadas o SCE. Reconocer manifestaciones clínicas y factores de riesgo es fundamental para el diagnóstico, con estudios auxiliares como precaución en niños. La faciotomía, tratamiento estándar de oro; no es inocua e impacta en la morbilidad. Se recomiendan protocolos oportunos para extravasación, valoración temprana por cirujano, investigaciones en pediatría.

Extravasation Compartment Syndrome (SCE) is an infrequent pathology, with an incidence of 0,01-6,5%, whom 1,8-11% are children. Communication in children is usually difficult, with high risk of development of SCE. A case about a 9 month old male patient with an over-infected viral pneumonia and a triggered SCE is presented. He received compartmental decompression of right forearm and right hand; however he presented mild sequelae. Treatment of extravasation injury is not always sufficient enough. Mild-to-moderate complications or SCE can be presented. Recognizing clinical manifestations and risk factors and the use of auxiliary studies is fundamental for a good diagnosis and as prevention in children. Faciotomies, gold standard for treatment, are not completely safe, and have an impact on morbidity. Early protocols against extravasation, early examination by surgeon and investigation about SCE in chil-dren are recommended.
