Why do microsurgeons use dextran?
Microsurgeons can use dextran to decrease the risk of vascular complications such as thrombosis. [6] This mechanism occurs via the antithrombotic effects of dextran binding to platelets, erythrocytes, and the vascular endothelium to decrease aggregation and adhesiveness.[7] Dextran reduces Von Willebrand factor to decrease the function of platelets.[8] It also activates plasminogen and prolongs bleeding time. These effects increase proportionally with the increase in the molecular weight of the dextran.
What is TC99M dextran?
Technetium Tc99m-labeled dextran by intravenous administration is a blood vascular imaging agent for the diagnosis of pericardial effusion, ventricular aneurysms, or bleeds.
Does dextran prolong bleeding?
Since dextran can prolong bleeding time and is antithrombotic, it is important to monitor its usage.[8] While it reduces emboli and adhesion of platelets, dextran effects increase proportionally with the molecular weight of the dextran administered. It is best to avoid exceeding the dosage recommended due to excess wound bleeding, melena, wound seroma, and volume overload. As dextran may negatively impact renal function, one should carefully watch for oliguria or anuria as a harbinger of renal failure.[10] Monitoring for serious systemic allergic reactions is also crucial, as elaborated upon previously.
Is dextran safe for heart failure?
It is relatively contraindicated in patients with untreated bleeding disorders, including platelet dysfunction, because of increased bleeding risk. Caution should be exercised in patients with heart failure, as rapid administration may prove dangerous due to the plasma volume expansion effects, potentially leading to circulatory overload and acute decompensation. However, even slower but continued administration may pose some risk as it may reduce plasma protein levels, which can reduce oncotic pressure and worsen edema. If volume overload occurs during dextran administration, an osmotic diuretic is the recommended intervention. For patients with underlying renal disease, failure to clear dextran can lead to worsening of renal function.[10] Other relative contraindications include severe liver disease, preexisting edema, asthma, diabetes, epilepsy, and seizures. [8][10][11]
Can dextran cause rash?
Adverse effects of dextran are uncommon when appropriately administered. However, focal allergic reactions at the injection site or systemic anaphylactic or anaphylactoid reactions are possible: the presence of rash, hives, wheezing, chest tightness, and shortness of breath should cue the healthcare provider to this possibility. Immediate discontinuation and emergency treatment with intravenous fluids and H1/H2 blockers, epinephrine, and steroids may be warranted in severe cases for supportive treatment and to prevent airway closure.[9] Other potential adverse reactions include nausea, vomiting, arthralgias, fevers, and pain. Local injection site reactions can include venous thrombosis, infections at the injection site, and febrile reactions. It is prudent to monitor the injection site closely.
Does dextran cause liver problems?
Hepatic effects of dextran toxicity can include abnormal liver function test results with increased AST and ALT values, especially in patients undergoing surgery or cardiac catheterization procedures; this is because dextran accumulates in hepatocytes where it is metabolized, and excess levels of dextran can lead to hepatic oxidative stress. [11]
How to calculate iron dextran dose?
I find it much simpler to do the following dose calculation: simply multiply the deficit for the hemoglobin (in grams) by 250mg (amount needed to form a pint of blood), and add an additional 1000 mg to replace the normal reserve amount.
How much iron dextran should I take for anaphylaxis?
The obvious benefit for this “ test dose/rapid desensitization ” method is to allow the patient to begin with a miniscule dose of iron dextran, rather than the package insert recommended 25mg, dose, which is sufficient to precipitate full-blown anaphylaxis if the patient is indeed sensitive. The tiny dose gives an opportunity for the patient to have a smaller reaction and for the medical personnel to stop the infusion quickly, before the adverse reaction can fully develop. On occasion, I have needed to slow an infusion, but none of my patients was unable to complete the full infusion, and no “medical resuscitation” beyond diphenhydramine and prednisone or dexamethasone has ever been required.
How much iron dextran is in a drip chamber?

What is high-molecular weight dextran?
High-molecular weight dextran is a plasma volume expander made from natural sources of sugar (glucose). It works by restoring blood plasma lost through severe bleeding.

How is iron dextran ingested?
Iron dextran is ingested via endocytosis by the macrophages of the reticuloendothelial system. The fusion of the newly formed endosome with acidic lysosome results in the cleavage of the carbohydrate shell and the release of ferrous iron (Fe[2+]). Following release from its complex, Fe(2+) is shuttled across the endolysosomal membrane into the cytoplasm via divalent metal transporter 1 (DMT1), where it can be stored as a Fe-ferritin complex or get shuttled into the blood via ferroportin, a transmembrane protein. Once in the blood, Fe(2+) is immediately oxidized to ferric iron (Fe[3+]) by ceruloplasmin and subsequently bound by transferrin for transport to various sites throughout the body for utilization (i.e.,, to bone marrow for hemoglobin synthesis or to the liver for storage). [2][3] Hematologic responses of iron dextran may be observed within 3 to 10 days.

Is iron dextran effective for chemotherapy?

Additionally, iron dextran is contraindicated in any form of anemia, which is not the result of iron deficiency. Co-administration with dimercaprol should be avoided as iron-dimercaprol chelates are especially toxic to renal tissue. Patients taking angiotensin-converting enzyme inhibitors may be at an elevated risk of developing adverse reactions. Additionally, caution is necessary when administering iron dextran to patients with any disease states that mimic known major adverse effects; disease states of concern include atopy, asthma, rheumatoid arthritis, and cardiovascular disease.

What is dextran solution?
Such a solution provides an osmotically neutral fluid that once in the body is digested by cells into glucose and free water. It is occasionally used to replace lost blood in emergency situations, when replacement blood is not available, but must be used with caution as it does not provide necessary electrolytes and can cause hyponatremia or other electrolyte disturbances.
What is dextran derived from?
Dextran is a complex branched glucan ( polysaccharide derived from the condensation of glucose ), originally derived from wine. IUPAC defines dextrans as "Branched poly-α-d-glucosides of microbial origin having glycosidic bonds predominantly C-1 → C-6". Dextran chains are of varying lengths (from 3 to 2000 kilodaltons ).
Why are dextran clots more easily lysed?
Clots formed after administration of dextrans are more easily lysed due to an altered thrombus structure (more evenly distributed platelets with coarser fibrin ). By inhibiting α-2 antiplasmin, dextran serves as a plasminogen activator, so possesses thrombolytic features.
How long does dextran stay in the blood?
The larger dextrans (>60,000 Da) are excreted poorly from the kidney, so remain in the blood for as long as weeks until they are metabolized. Consequently, they have prolonged antithrombotic and colloidal effects. In this family, dextran-40 (MW: 40,000 Da), has been the most popular member for anticoagulation therapy.
How are dextrans separated?
They are separated by fractional precipitation from protein-free extracts using ethanol. Some bacteria coproduce fructans, which can complicate isolation of the dextrans.

Close to 70% of dextran-40 is excreted in urine within the first 24 hours after intravenous infusion, while the remaining 30% are retained for several more days.
Does dextran reduce vascular thrombosis?
These agents are used commonly by microsurgeons to decrease vascular thrombosis. The antithrombotic effect of dextran is mediated through its binding of erythrocytes, platelets, and vascular endothelium, increasing their electronegativity and thus reducing erythrocyte aggregation and platelet adhesiveness.
