I-Tenecteplase - Ukusetshenziswa, Isilinganiso, Imiphumela Engemihle Nokunye Okuningi

I-Tenecteplase umuthi osetshenziswa kakhulu ekwelapheni i-acute myocardial infarction, eyaziwa ngokuthi ukuhlaselwa yinhliziyo. Iyisithako esiqeda i-thrombolytic, okusho ukuthi isiza ekuncibilikiseni amahlule egazi avimba ukugeleza kwegazi enhliziyweni. Ngokubuyisela ukugeleza kwegazi, i-Tenecteplase ingasiza ekunciphiseni ukulimala kwenhliziyo futhi ithuthukise imiphumela yeziguli ezihlaselwa yinhliziyo.

Ukusetshenziswa kwe-Tenecteplase

I-Tenecteplase ivunyelwe kakhulu ukusetshenziswa kwezokwelapha okulandelayo:

• I-Acute Myocardial Infarction: Isetshenziswa ngaphandle kwelebula noma kumaphrothokholi athile okwelapha nge-thrombolytic kuma-acute coronary syndromes ngale kwe-STEMI (isb., amanye amacala e-NSTEMI anobungozi obukhulu), kodwa ukuvunyelwa okuyinhloko kungokwe-STEMI.
• I-Thrombolysis: Isetshenziswa ngaphandle kwelebula noma kumaphrothokholi athile okwelapha nge-thrombolytic kuma-acute coronary syndromes ngale kwe-STEMI (isb., amanye amacala e-NSTEMI anobungozi obukhulu), kodwa ukuvunyelwa okuyinhloko kungokwe-STEMI.

Isebenza kanjani?

I-Tenecteplase isebenza ngokwenza i-plasminogen isebenze, iphrotheni egazini eguqulwa ibe yi-plasmin. I-Plasmin iyi-enzyme ephula i-fibrin, ingxenye ebalulekile yamahlule egazi. Ngokukhuthaza ukuqhekeka kwala mahlule, i-Tenecteplase isiza ukubuyisela ukugeleza kwegazi okuvamile emisipheni yenhliziyo, inciphise ingozi yokulimala okwengeziwe futhi ithuthukise amathuba okululama.

Isilinganiso nokuphathwa

I-Tenecteplase inikezwa ngomjovo, ngokuvamile inikezwa esibhedlela. Imithamo enconywayo isekelwe esisindweni:

• <60 kg: 30 mg;
• 60?69 kg: 35 mg;
• 70?79 kg: 40 mg;
• 80?89 kg: 45 mg;
• ?90 kg: 50 mg njenge-bolus eyodwa ye-IV ngemizuzwana emi-5.

Ukusetshenziswa kwezingane akuvunyelwe yi-FDA futhi kudinga ukuzimisela kochwepheshe. Kubalulekile ukunikeza i-Tenecteplase ngokushesha okukhulu ngemva kokuqala kwezimpawu ukuze kusebenze kahle kakhulu.

Imiphumela Engemihle ye-Tenecteplase

Imiphumela emibi evamile ye-Tenecteplase ingafaka:

• Ukopha (okuncane noma okukhulu)
• I-Hypotension
• I-nausea
• Ukuvota
• Fever

Imiphumela emibi kakhulu ingabandakanya:

• Ukungezwani komzimba okukhulu
• Ukopha kwegazi ngaphakathi kobuchopho (ukopha ebuchosheni)
• Ukuphazamiseka kwenhliziyo (isb., ukungasebenzi kahle kwenhliziyo noma ukuqhekeka kwemithambo yegazi)

Iziguli kufanele zifune usizo lwezokwelapha ngokushesha uma zithola imiphumela emibi kakhulu.

Ukusebenzisana kwezidakamizwa

I-Tenecteplase ingasebenzisana nemithi eminingana, okungase kwandise ingozi yokopha. Ukusebenzisana okukhulu kwemithi kuhlanganisa:

• Ama-anticoagulant: (isb., i-warfarin, i-heparin)
• Ama-antiplatelet agents: (isb., i-aspirin, i-clopidogrel)
• Izidakamizwa ezingezona ukuvuvukala (ama-NSAID)
• Ama-anticoagulant omlomo aqondile (isb., i-apixaban)
• I-Thrombolytics, noma i-GP IIb/IIIa inhibitors

Kubalulekile ukwazisa umhlinzeki wakho wezempilo mayelana nayo yonke imithi oyiphuzayo ukuze ugweme ukusebenzisana okungenzeka.

Izinzuzo ze-Tenecteplase

Izinzuzo zezokwelapha zokusebenzisa i-Tenecteplase zifaka:

• Isenzo esisheshayo ekuncibilikiseni amahlule singanciphisa kakhulu umonakalo wenhliziyo.
• Ukuphathwa kwe-bolus eyodwa, okwenza kube lula ukuyisebenzisa ezimweni eziphuthumayo.
• Ukusebenza kahle okuqinisekisiwe ekuthuthukiseni amazinga okusinda kanye nemiphumela ezigulini ezine-STEMI.

Ukuphikisana kwe-Tenecteplase

Abantu abathile kufanele bagweme ukusebenzisa i-Tenecteplase, okuhlanganisa:

• Iziguli ezinomlando wesifo sohlangothi oluphuma igazi, isifo sohlangothi esisanda kwenzeka (ezinyangeni ezi-3) esibangelwa yisifo sohlangothi oluphuma igazi, ukopha okusebenzayo, isilonda se-peptic esisebenzayo, noma i-diathesis yokopha eyaziwayo.
• Labo abanomfutho wegazi ophakeme ongalawuleki kakhulu.
• Abantu abanolwazi lokuzwela kakhulu i-Tenecteplase noma ezinye izingxenye zayo.
• Abesifazane abakhulelwe (Isigaba C) kufanele baxhumane nomhlinzeki wabo wezempilo ngaphambi kokusebenzisa.

Ukuqapha Nezexwayiso

Ngaphambi kokusebenzisa i-Tenecteplase, iziguli kufanele zenze izivivinyo ezithile zelebhu ukuze zihlole ingozi yazo yokopha. Abahlinzeki bezempilo bangaqapha umfutho wegazi futhi benze izifundo zezithombe ukuze banqume noma yikuphi ukuphikisana. Kubalulekile ukuxoxa nganoma yimuphi umlando wezokwelapha, ikakhulukazi ohlobene nezinkinga zokopha noma ukuhlinzwa kwamuva, nodokotela wakho.
