I-Dobutamine - Ukusetshenziswa, Isilinganiso, Imiphumela Engemihle Nokunye

Iyini i-Dobutamine?

I-Dobutamine umuthi osetshenziswa kakhulu ekwelapheni izimo ezihlobene nenhliziyo. Ingesigaba semithi eyaziwa ngokuthi i-inotropes, esiza ekuthuthukiseni ikhono lenhliziyo lokupompa igazi. I-Dobutamine ivame ukunikezwa esibhedlela, ikakhulukazi ezigulini ezinenkinga yokwehluleka kwenhliziyo noma ezivivinywa ukucindezeleka kwenhliziyo ngezinhlobo ezithile. Ikhono layo lokuthuthukisa ukuphuma kwenhliziyo lenza kube ithuluzi elibalulekile kwezokwelapha ezibucayi.

Ukusetshenziswa kwe-Dobutamine

I-Dobutamine ivunyelwe ukusetshenziswa kwezokwelapha eziningana, okuhlanganisa:

• Ukwehluleka kwenhliziyo: Ngokuvamile isetshenziswa ekwelapheni ukwehluleka kwenhliziyo okukhulu, lapho inhliziyo ingakwazi ukupompa igazi elanele ukuhlangabezana nezidingo zomzimba.
• I-Cardiogenic Shock: Lesi simo senzeka lapho inhliziyo ingakwazi ukupompa igazi elanele ngokuzumayo, ngokuvamile ngemva kokuhlaselwa yinhliziyo.
• Ukuhlolwa Kokucindezeleka Kwenhliziyo: I-Dobutamine ingasetshenziswa ukulingisa ukuzivocavoca ezigulini ezingakwazi ukwenza izivivinyo zokucindezeleka ngokomzimba, okusiza ekuhloleni ukusebenza kwenhliziyo.
• Ukushaqeka kwe-Septic: Kwezinye izimo, ingasetshenziswa ukuthuthukisa ukusebenza kwenhliziyo ezigulini ezine-septic shock.

Indlela Esebenza

I-Dobutamine isebenza ngokuvuselela ama-receptor e-beta1 adrenergic enhliziyweni. Lokhu kuvuselela kwandisa ukugoba kwenhliziyo, okusho ukuthi inhliziyo ishaya ngamandla kakhulu. Inemiphumela emincane neguquguqukayo emithanjeni yegazi futhi ngokuyinhloko yandisa ukuphuma kwenhliziyo. Ngamagama alula, cabanga nge-dobutamine njengesikhuthazi senhliziyo, esiza ukuthi isebenze kahle kakhulu lapho ibhekene nobunzima.

Isilinganiso nokuphathwa

I-Dobutamine ivame ukunikezwa ngokufaka i-intravenous (IV) endaweni yesibhedlela. Umthamo ojwayelekile wabantu abadala uvame ukuqala kuma-microgram angu-2 kuya kwangu-20 ngekhilogramu yesisindo somzimba ngomzuzu, ulungiswe ngokusekelwe empendulweni yesiguli. Ezigulini zezingane, umthamo ungahluka, futhi abahlinzeki bezempilo bazonquma inani elifanele ngokusekelwe esisindweni nesimo sengane. Ukuqapha okuqhubekayo kubalulekile ngesikhathi sokuphathwa ukuqinisekisa ukuphepha nokusebenza kahle.

Imiphumela Engemihle ye-Dobutamine

Nakuba i-dobutamine ingaba wusizo, ingase futhi ibangele imiphumela emibi. Imiphumela emibi evamile ihlanganisa:

• Ukwanda kwesilinganiso senhliziyo (i-tachycardia)
• Izinguquko kumfutho wegazi
• I-nausea
• bekhanda
• palpitations

Imiphumela emibi kakhulu, nakuba ingavamile, ingabandakanya:

• I-Arrhythmias (ukushaya kwenhliziyo okungajwayelekile)
• ubuhlungu besifuba
• Ukungezwani komzimba okukhulu
• Ukwehluleka kwenhliziyo okuya ngokuya kuba kubi

Iziguli kufanele ziqashwe ngokucophelela ukuze zithole noma yimiphi imiphumela emibi ngesikhathi sokwelashwa.

Ukusebenzisana kwezidakamizwa

I-Dobutamine ingasebenzisana nemithi eminingana, okungashintsha ukusebenza kwayo noma kwandise ingozi yemiphumela emibi. Ukusebenzisana okukhulu kwemithi kufaka phakathi:

• Ama-Beta-blockers: Lawa anganciphisa ukusebenza kahle kwe-dobutamine.
• I-Monoamine oxidase inhibitors (MAOIs) kanye ne-tricyclic antidepressants: Ingathuthukisa imiphumela yenhliziyo nemithambo yegazi.
• Eminye imithi yenhliziyo: Kudingeka ukuqapha ngokucophelela uma kusetshenziswa neminye imithi yokwelapha umfutho wegazi ophakeme noma imithi yokunciphisa umfutho wegazi.

Ngaso sonke isikhathi wazisa umhlinzeki wakho wezempilo mayelana nayo yonke imithi oyiphuzayo ukuze ugweme ukusebenzisana okungenzeka.

Izinzuzo ze-Dobutamine

Izinzuzo zezokwelapha zokusebenzisa i-dobutamine zifaka:

• Isenzo esisheshayo: Isebenza ngokushesha ukuthuthukisa ukusebenza kwenhliziyo, okuyinto ebalulekile ezimweni eziphuthumayo.
• Umphumela Othuthukisiwe Wenhliziyo: Kusiza iziguli ezinesifo senhliziyo noma ukushaqeka ngokuthuthukisa ukugeleza kwegazi kanye nokulethwa komoya-mpilo ezithweni ezibalulekile.
• Ukusetshenziswa Okuhlukahlukene: Isebenza kahle ezindaweni ezahlukene, okuhlanganisa ukunakekelwa okusheshayo kanye nokuhlolwa kokuxilonga.

Ukuphikisana kwe-Dobutamine

Abantu abathile kufanele bagweme i-dobutamine, okuhlanganisa:

• Iziguli ezinesifo sokungezwani komzimba: Labo abaye baba nokusabela kokungezwani komzimba ne-dobutamine noma imithi efanayo.
• I-aortic stenosis enzima: Isimo lapho i-aortic valve yenhliziyo incipha khona, okungaba kubi kakhulu uma inhliziyo ikhipha igazi eliningi.
• Izifo ezithile zokushaya kwenhliziyo: Iziguli ezinezinhlobo ezithile zokushaya kwenhliziyo okungajwayelekile (ama-tachyarrhythmia angalawulwa) zingase zibe sengozini.

I-Dobutamine kufanele isetshenziswe ngesikhathi sokukhulelwa noma sokuncelisa kuphela uma kudingeka ngokucacile futhi ngaphansi kokuqashwa ngudokotela.

Ukuqapha Nezexwayiso

Ngaphambi kokuqala i-dobutamine, iziguli kungadingeka zenze izivivinyo ezithile zelebhu ukuze kuhlolwe ukusebenza kwenhliziyo kanye nempilo iyonke. Kubalulekile ukuqapha izinga lokushaya kwenhliziyo kanye nomfutho wegazi eduze ngesikhathi sokwelashwa. Iziguli ezinomlando wesifo senhliziyo, umfutho wegazi ophakeme, noma ezinye izinkinga zenhliziyo kufanele zixoxe nodokotela wazo ngomlando wazo wezokwelapha.
