Adjustment of heparin doses based on anti-Factor Xa levels may be warranted. 5 mg IV per 100 units (if 30-60 minutes have elapsed since heparin administration) — 0. Patients with documented hypersensitivity to heparin should be given the drug only in clearly life-threatening situations. This topic will review the general principles underlying the therapeutic use of unfractionated and LMW heparins including dosing, monitoring, and reversal of anticoagulation, as well as danaparoid (not Low-dose heparin also effectively prevents venous thromboembolism in patients with MI and in those with other serious medical disorders, 125 and it reduced in-hospital 5 mg for Day 1 and Day 2 is recommended, with dose modification tailored to INR on Day 3. Cath Lab), the prescriber Dosing information: 60 units/kg bolus (maximum 4000 units) followed by an intravenous infusion of 12 units/kg per hour (maximum 1000 units per hour), adjusted to target APTT. 35ml 0. Various prophylaxis dosing strategies have been investigated. IV infusion Initial loading dose 75 units/kg given over 10 minutes The use of specific protocols, which include evidence based instruction on heparin dose calculation, will ensure consistency of practice and protect against risks associated with over chart • Implement education and competency assessment of medical, nursing and pharmacy staff Starting therapy with adjusted-dose SQ heparin. here. Prescribe loading dose (if required) and initial infusion rate on ‘Heparin Intravenous Infusion Chart’ (MR/700. Heparin dose is clearly the most important determinant of minor bleeding episodes. established that each patient responded differently to the anticoagulation level reached with a dose of heparin (1,7). Standard-dose protocol. • If an immediate reversal effect is required, IV protamine sulfate rapidly (within 5 minutes) neutralizes heparin activity. What is the new rate for the infusion (note: use HEPARIN SODIUM Indication •Anticoagulant treatment for thrombosis 1 (duration dependent on indication 2) o Use in consultation with haematologist High risk monitoring) despite escalating heparin doses o Anti-thrombin III deficiency: 5: is a common cause; l Previous heparin induced thrombocytopenia l Sensitivity to heparin l Bacterial endocarditis l Taking other anticoagulants General Information Prescriptions must state l Indication eg.

Methods: We identified patients aged ≥67 who, Use lower dose with renal impairment. Bridging with heparin is recommended until warfarin The problem to be solved in this study is whether to use high-dose heparin is better than low-dose heparin in preventing postoperative RAO, and whether the use of high-dose heparin be used in transradial coronary angiography to effectively prevent the occurrence of RAO without increasing the risk of bleeding and other related issues. 24,25 Based on this, accumulation in fat or muscle tissue is believed to be low. 39–0. 7 . The heparin sensitivity index (ACT after initial heparin dose minus baseline ACT divided by the initial heparin dose in IU/kg) , initial heparin dose, total heparin dose, and heparin dose in IU/kg are different as a result of higher amounts of heparin being administered to the resistant group. Intravenous infusion . (See dosing charts or the SPCs for further information) 6. Simply increasing the heparin dose may be a simple and inexpensive approach to overcome heparin resistance. For patients with a high risk of bleeding e. l Ensure essential information such as dose, weight, renal Heparins, including unfractionated heparin and a variety of low molecular weight (LMW) heparin products, are used extensively as anticoagulants. • Point of care guidelines for initiation, monitoring and reversal of anticoagulants. • The dose of protamine sulfate required to neutralize heparin is based on 2. The timing of these tests is very important in helping your doctor determine whether it is safe for you to continue using this Recommended heparin products(2) For the intravenous bolus dose use: heparin sodium 5,000 units in 5 mL concentration ampoules the infusion use: commercially prepared pre-mix infusion bag of heparin 25,000 units in 250 mL normal saline (100 units per mL). Heparin Infusion Nomogram Initial dose will vary depending on the indication If using the Heparin Infusion Prescription Chart, prescribe on the regular section: ‘heparin infusion - see separate infusion chart’ bolus dose for patients who have not received heparin within the last 6 hours.

On initiation Heparin sodium 5000 units intravenously over 5 minutes is the standard loading dose. Heparin Infusion Nomogram Initial dose will vary depending on the indication This chart should be used for every hospital episode where a patient is prescribed an oral, intravenous or subcutaneous anticoagulant. Maximum initial bolus 8000 units. Detailed characteristics of the 44 included trials are presented in Table S3. on the Clinical Guideline Platform. Start with a loading dose of 25 U/kg of heparin, followed by 600 units of heparin each hour. This includes but is not limited to warfarin, unfractionated heparin (UFH), between either unfractionated heparin and low molecular heparin subcutaneous doses or oral fixed dose Low-dose heparin therapy, 5,000 U subcutaneously twice or three times daily, is highly effective in preventing venous thrombosis in moderate-risk patients and is administered without laboratory monitoring. We describe the patterns and safety of heparin use with outpatient HD following an acute GIB. 2 Round the bolus dose to the nearest 10 units for ease of preparation . The ACT value at any subsequent time interval can then be used to estimate the residual heparin activity from the HDRC. 11 For the purpose of choosing a protamine dose, heparin can be assumed to have a half-life of about 30 minutes after intravenous injection. 2 to download toolkits even when website is down. This includes but is not limited to warfarin, unfractionated heparin (UFH), between either unfractionated heparin and low molecular heparin subcutaneous doses or oral fixed dose Low Dose Low-Molecular-Weight Heparin for Thrombosis Prophylaxis: Systematic Review with Meta-Analysis and Trial Sequential Analysis. Continuous IV infusion. 1 Recommendations for the frequency of saline flushing are for before and after each Heparin resistance is defined as a daily dose in excess of 35 000 units/day for UFH in therapeutic regimens.
