Heparin, Warfarin ak Laboratwa ki Dirije yo

🧠 Poukisa sa enpòtan

HEPARIN aji nan kèk minit; yo siveye perfusion IV yo ak aPTT, ak yon objektif terapetik ki se anviwon 1.5 a 2.5 fwa valè kontwòl la (souvan anviwon 60 a 80 segonn, selon laboratwa a). Antidòt la se PROTAMINE SULFATE. Veye HEPARIN-INDUCED THROMBOCYTOPENIA: yon bès plakèt ki se 50% oswa plis pase nivo debaz la oswa yon kantite anba 100,000, anjeneral 5 a 10 jou apre heparin kòmanse; sispann tout heparin epi rapòte li. Yo bay heparin ki gen pwa molekilè ba (enoxaparin) anba po nan vant, ak ti boul lè a ki rete nan sereng la epi san fwote sit la. WARFARIN pran 3 a 5 jou pou li aji (kidonk li sipèpoze ak heparin), yo siveye li ak INR, ak yon objektif abityèl ki se 2 a 3 (2.5 a 3.5 pou kèk valv mekanik), epi yo ranvèse li ak VITAMIN K (phytonadione); li kontr-endike pandan gwosès. Anseye pasyan an pou li pran vitamin K nan yon kantite ki regilye, pou li pa pran aspirin oswa NSAIDs san apwobasyon, pou li itilize yon razwa elektrik ak yon bwòs dan ki mou, epi pou li rapòte poupou nwa, san nan pipi, jansiv ki senyen oswa boul ble ki pa abityèl. Antikoagilan oral dirèk yo (apixaban, rivaroxaban, dabigatran) pa bezwen siveyans laboratwa regilye; yo ranvèse dabigatran ak idarucizumab.

HEPARIN works within minutes; IV infusions are monitored with aPTT, with a therapeutic goal of about 1.5 to 2.5 times the control value (often about 60 to 80 seconds, depending on the laboratory). The antidote is PROTAMINE SULFATE. Watch for HEPARIN-INDUCED THROMBOCYTOPENIA: a platelet drop of 50% or more from baseline or a count below 100,000, usually 5 to 10 days after heparin starts; stop all heparin and report. Low-molecular-weight heparin (enoxaparin) is given subcutaneously in the abdomen, with the air bubble left in the syringe and without rubbing the site. WARFARIN takes 3 to 5 days to work (so it overlaps with heparin), is monitored with the INR, with a usual goal of 2 to 3 (2.5 to 3.5 for some mechanical valves), and is reversed with VITAMIN K (phytonadione); it is contraindicated in pregnancy. Teach consistent vitamin K intake, no aspirin or NSAIDs without approval, an electric razor and a soft toothbrush, and to report black stools, blood in urine, bleeding gums or unusual bruising. Direct oral anticoagulants (apixaban, rivaroxaban, dabigatran) need no routine lab monitoring; dabigatran is reversed with idarucizumab.

🏥 Nan lavi reyèl

📉 Yon pasyan nan jou 6 yon perfusion heparin gen yon aPTT ki se 110 segonn ak nouvo san nan pipi a. Enfimyè a sispann perfusion an, li avèti founisè a epi li prepare protamine. Nan demen, jou 7 terapi heparin lan, plakèt yo desann soti 220,000 a 90,000: yo sispèk trombositopeni ke heparin pwoke. Tout heparin, menm sa yo itilize pou rense yo, sispann nèt epi yo avèti founisè a. De pwoblèm diferan, yon sèl medikaman, toulede se laboratwa egzamen an atann ou konnen yo ki kenbe yo.

📉 A client on day 6 of a heparin drip has an aPTT of 110 seconds and new blood in the urine. The nurse stops the infusion, notifies the provider and prepares protamine. The next day, day 7 of heparin therapy, the platelets have dropped from 220,000 to 90,000: suspected heparin-induced thrombocytopenia. All heparin, including flushes, is stopped permanently and the provider is notified. Two different problems, one drug, both caught by the labs the exam expects you to know.

• Protamine ranvèse heparin; vitamin K ranvèse warfarinProtamine reverses heparin; vitamin K reverses warfarin
• Yon bès plakèt ki se 50% oswa plis (oswa anba 100,000) 5 a 10 jou apre heparin kòmanse sijere HIT: sispann tout heparin epi rapòte liA platelet drop of 50% or more (or below 100,000) 5 to 10 days into heparin suggests HIT: stop all heparin and report
