Protamine sulfate is a medication that is used to reverse the effects of heparin. [3] It is specifically used in heparin overdose, in low molecular weight heparin overdose, and to reverse the effects of heparin during delivery and heart surgery. [3] [4] It is given by injection into a vein. [3] The onset of effects is typically within five ...
Rotating the injection site is the primary method of preventing changes in tissue structure from insulin administration. [15] Heparin-based anticoagulants injected subcutaneously may cause hematoma and bruising around the injection site due to their anticoagulant effect. This includes heparin and low molecular weight heparin products such as ...
A bolus delivered directly to the veins through an intravenous drip allows a much faster delivery which quickly raises the concentration of the substance in the blood to an effective level. This is typically done at the beginning of a treatment or after a removal of medicine from blood (e.g. through dialysis ).
Heparin, also known as unfractionated heparin (UFH), is a medication and naturally occurring glycosaminoglycan. [3] [4] Heparin is a blood anticoagulant that increases the activity of antithrombin. [5] It is used in the treatment of heart attacks and unstable angina. [3] It can be given intravenously or by injection under the skin. [3]
Average molecular weight: heparin is about 15 kDa, and LMWH is about 4.5 kDa. [25] Less frequent subcutaneous dosing than for heparin for postoperative prophylaxis of venous thromboembolism. Once or twice daily subcutaneous injection for treatment of venous thromboembolism and in unstable angina instead of intravenous infusion of high-dose heparin.
Initial treatment generally consists of intravenous fluids to manage dehydration, intravenous insulin in those with significant ketones, low molecular weight heparin to decrease the risk of blood clotting, and antibiotics among those in whom there are concerns of infection. [3] The goal is a slow decline in blood sugar levels. [3]
The long acting insulin is given once (usually glargine, Lantus) or twice (usually detemir, Levemir) daily to provide a base, or basal insulin level. Rapid acting (RA) insulin is given before meals and snacks. A similar profile can be provided using an insulin pump where rapid acting insulin is given as the basal and premeal bolus insulin.
This became Connaught' second product, after insulin, to be recognised as an international standard. Gordon Murray, a prominent surgeon based at Toronto General Hospital, demonstrated that heparin effectively cleared up internal blood clots and that it showed promise in dangerous operations in which blood would otherwise thicken too quickly.
