No antidote for LMWH overdose, 60% of the anticoagulant effect of LMWH can also be neutralized by protamine sulphate Heparin, fondaparinux inhibits only factor Xa. Unfractionated heparin (UFH), the Low molecular weight heparins (LMWH) inhibit both factors Xa and IIa, but the synthetic (LMWH), include enoxaparin, dalteparin, and tinzaparin. Protamine sulphate, its antidote Low molecular weight heparin The bleeding with heparin, is very severe, and potentially disastrous, but its effects can be rapidly reversed with
Others such as osteoporosis and hyperaldosteronism after long Heparin administration are, increase in clotting time, amongst Heparin is also present in our body, in the mast cellsĪs granules, of the liver lung and intestines. Xa and IX a, and thus prevents conversion of fibrinogen to fibrin. In ATIII, and thus heparin inactivated coagulation factors, IIa, (antihrombin- II), which produces a marked structural change Actually this effect is mediated by heparins binding to AT II Has a high affinity in binding and inactivating ATIII (antithrombin Of alternating glucosamine and uronic acid elements, and itsĪnticoagulant effect is due to heparin pentasaccharide, which Occurs in a very small subset of patients, irrespective of theĭose of administration of heparin. Heparin is a very common anticoagulant, this complication only

Heparin induced thrombocytopenia, is a serious complication of heparin administration, that includes disastrous complications like arterial and venous embolisms, skin necrosis, limbĪnd organ ischemia, apart from low platelet counts. PTE, monitor resolution of his thrombocytopenia and DVT. He was scheduled for routine follow-ups, for early detection of a recurrent Months in lieu of symptomatic pulmonary embolism, and heparin induced thrombocytopenia with thrombosis. On suspecting HIT, heparin was immediately stopped, and direct oral anticoagulants were started- abixaban, a factor X a inhibitor, for 6 With the PTE or if it was due to heparin, due to a syndromeĬalled heparin induced thrombocytopenia, (HIT). Remains unknown that if he developed the DVT in his calf, along Started experiencing right calf pain, on a Doppler US of the rightĬalf, he was found to have a 2.2 cm long, deep vein thrombus. Week ago it dropped down to 52,000/ micro L and soon after he Thus a diagnosisĪ week after he presented, his laboratory results showedĪ distinctive drop in platelets count, from the normal range, a Of 4.5 points put him into a low probability of PE, anticoagulation was started and a HRCT was ordered, which showed, aįilling defect in a sub-segmental pulmonary vasculature, whichīecame evident after contrast enhancement. Empiric anticoagulation with unfractionated heparin was sought. A diagnosis of pulmonary thrombo-embolism byĮxclusion was considered. Normal ECGs, normal echocardiography and an unremarkableĬhest X-ray. Many differential diagnoses such as angina, pneumothorax were rejected due to Stated on intravenous fluids, vasopressors. Pressure, systolic was 90 mmHg and his HR was 113/min, was Her Leukocyte count was 10.0 x103 per µL, hemoglobin was 13.1 g/dL, and Of 104 mmol/L, bicarbonate of 22 mmol/L, BUN of 15 mg/dL,Ĭreatinine of 1.0 mg/dL and glucose of 92 mg/dL. His serum electrolytes were serum sodium of 132 mmol/L, potassium of 3.6 mmol/L, chloride He arrived to the ED, 5 hours after developing SOB his RR was 20/min. 30 hours after landing, he developed severe He wasn’t dehydrated, was not on any medication, and did not Thrombus, which presented 30 hrs after he took an 8 hour flight. This is a case report about a 42 year old male, of Asian ethnicity, without any significant PMH developed a pulmonary
