Overview
DESCRIPTION LMD (dextran 40) is a sterile, nonpyrogenic preparation of low molecular weight dextran (average mol. wt. 40,000) in 5% Dextrose Injection or 0.9% Sodium Chloride Injection. It is administered by intravenous infusion.
Uses
INDICATIONS AND USAGE LMD (dextran 40) is indicated for use in the adjunctive treatment of shock or impending shock due to hemorrhage, burns, surgery or other trauma. It is not indicated as a replacement for whole blood or blood components if they are available. It should not replace other forms of therapy known to be of value in the treatment of shock. LMD is also indicated for use as a priming fluid, either as a sole prime or as an additive, in pump oxygenators during extracorporeal circulation. LMD is also indicated for use in prophylaxis of venous thrombosis and pulmonary embolism in patients undergoing procedures known to be associated with a high incidence of thromboembolic complications, such as hip surgery.
Dosage
DOSAGE AND ADMINISTRATION LMD (dextran 40) is administered by I.V. infusion only. Dextran 1 should be administered prior to administration of clinical dextran solutions. 1. In shock, it is suggested that total dosage not exceed 20 mL/kg for adults and adolescents, during the first 24 hours. The first 10 mL/kg may be infused as rapidly as necessary to effect improvement. It is strongly recommended that central venous pressure be monitored frequently during the initial infusion of the drug. Should therapy continue beyond 24 hours, subsequent dosage should not exceed 10 mL/kg per day and therapy should not continue beyond five days. 2. In extracorporeal perfusion, the dosage of LMD used will vary with the volume of the pump oxygenator.
Side Effects
ADVERSE REACTIONS Antigenicity of dextrans is directly related to their degree of branching. Since LMD (dextran 40) has a low degree of branching, it is relatively free of antigenic effect. However, a few individuals have experienced mild urticarial reactions. More severe reactions, consisting of severe anaphylactoid reaction, generalized urticaria, tightness of the chest, wheezing, hypotension, nausea and vomiting may occur in rare instances. Symptoms and signs of adverse systemic reaction may be relieved by parenteral administration of antihistamines, ephedrine or epinephrine, while other means of shock therapy are instituted. The route of administration and dosages of the therapeutic agent selected will depend upon the severity and rapidity of progression of the reaction.
Warnings
WARNINGS Although infrequent, severe and fatal anaphylactoid reactions consisting of marked hypotension or cardiac and respiratory arrest have been reported, most of these reactions have occurred in patients not previously exposed to intravenous dextran and early in the infusion period. It is strongly recommended, therefore, that patients not previously exposed to dextran be observed closely during the first minutes of the infusion period. Anaphylactoid Reactions There have been rare reports of serious and life-threatening dextran-induced anaphylactoid reactions (DIAR) associated with Dextran 40 and Dextran 70 administration. To reduce the likelihood of DIAR, 20 mL dextran 1 should be administered prior to infusion of Dextran 40 or Dextran 70 consistent with the dextran 1 package insert. CONTRAINDICATIONS LMD (dextran 40) is contraindicated in patients with known hypersensitivity to dextran, in those with marked hemostatic defects of all types (thrombocytopenia, hypofibrinogenemia, etc.) including those caused by drugs (heparin, warfarin, etc.), marked cardiac decompensation and in renal disease with severe oliguria or anuria.
