Adenosine

Intshayelelo yeAdenosine

I-Adenosine yi-purine nucleoside yendalo edlala indima ebalulekileyo ekudlulisweni kwamandla eseli kunye nokuhambisa imiqondiso. Kwizonyango zeklinikhi, isetyenziswa kakhulu njenge-arhente ye-antiarrhythmic esebenza ngokukhawuleza ukulawula i-paroxysmal supraventricular tachycardia (PSVT). Ngokucothisa ukuhamba kwentliziyo okwethutyana kwi-atrioventricular (AV) node, i-adenosine inceda ukubuyisela isigqi sentliziyo esiqhelekileyo, okwenza ukuba ibe liyeza elisindisa ubomi kunyango olungxamisekileyo lwentliziyo. Ikwasetyenziswa ekuxilongweni kovavanyo loxinzelelo lwentliziyo ukuvavanya ukuvuza kwegazi emithanjeni yentliziyo. Esi sikhokelo sibonelela ngophononongo olunzulu lwe-adenosine, sigubungela ukusetyenziswa kwayo, iidosi ezicetyiswayo, iziphumo ebezingalindelekanga ezinokubakho, ukusebenzisana namanye amayeza, kunye nemibuzo ebuzwa rhoqo ukukunceda uqonde indima yonyango yale mayeza.

Yintoni iAdenosine?

I-Adenosine yi-purine nucleoside endogenous ekhoyo kuzo zonke iiseli zomntu. Ngokwezonyango, ihlelwa njenge-arhente ye-Class V antiarrhythmic. Xa ifakwa ngemithambo, i-adenosine isebenza ngokukhawuleza ukuphazamisa iindlela zokungena kwakhona entliziyweni ezibangela i-supraventricular tachycardia (SVT). Ngenxa yokuba isiqingatha sayo sobomi sifutshane kakhulu (ngaphantsi kwemizuzwana eli-10), iziphumo zayo zifutshane kodwa zisebenza kakhulu ekulawuleni i-rhythm ngokukhawuleza.

Ukusetyenziswa kweAdenosine

• Unyango lwe-Supraventricular Tachycardia (SVT): I-Adenosine idla ngokuba lolona nyango luphambili lwe-SVT. Isebenza ngokunciphisa isantya sokuhanjiswa kwee-electrical impulses kwi-atrioventricular (AV) node, inceda ekubuyiseleni isigqi sentliziyo esiqhelekileyo.
• Ukuxilongwa kweeMeko zeNtliziyo: Ukongezelela ekuphatheni i-arrhythmias, i-adenosine ngamanye amaxesha isetyenziswa njengesixhobo sokuxilonga ngexesha lovavanyo loxinzelelo lokuvavanya umsebenzi we-coronary artery.
• Olunye usetyenziso loMfuniselo: Abaphandi baphanda amandla e-adenosine ekunyangeni ezinye iimeko zempilo, njengemiphumo yayo ekulawuleni iintlungu kunye neengxaki ze-neurodegenerative. Nangona kunjalo, ezi zicelo zisafundwa.

Isisombululo kunye noLawulo

I-Adenosine kufuneka inikwe phantsi kweliso likagqirha ngenxa yempembelelo yayo enamandla kwisantya sentliziyo. Umthamo kunye nolawulo luxhomekeke kwimeko yesigulana, ubudala, kunye nobunzima bomzimba.

• Umthamo wabadala weArrhythmias: Ngokuqhelekileyo, i-dose yokuqala ye-6 mg ilawulwa njenge-injection esheshayo ye-intravenous (IV). Ukuba umphumo ofunwayo awufezekanga, umthamo wesibini we-12 mg unokunikwa.
• Umthamo Wabantwana: Ebantwaneni, idosi idla ngokuba yi-0.05 ukuya kwi-0.1 mg/kg elawulwa njengenaliti ye-IV. Idosi inokunyuswa ngokuthe ngcembe ukuba kuyimfuneko.
• Iingcebiso zoLawulo: Isitofu sinikezelwa ngokukhawuleza, ngokuqhelekileyo kulandelwa yi-saline flush ukuqinisekisa ukuhanjiswa okusebenzayo kwigazi.

Iziphumo ezisecaleni zeAdenosine

Nangona i-adenosine ikhuselekile xa isetyenziswa phantsi kweliso likagqirha, inokubangela iziphumo ebezingalindelekanga kwabanye abantu. Ezi ziphumo bezihlala zisenzeka okwexeshana kwaye ziphela ngokukhawuleza, kodwa kubalulekile ukuba uzazi.

Iziphumo eziPhakathi

• Ukugungxula: Ukuvakalelwa ngokukhawuleza kokufudumala okanye ubomvu kunokwenzeka, ngakumbi ebusweni.
• Iintlungu zesifuba okanye ukuqina: Abanye abantu banokuziva bengakhululekanga esifubeni.
• Isiyezi okanye Ubuncinci: Impembelelo ye-Adenosine kwisantya sentliziyo ngamanye amaxesha inokubangela ukuziva unesizungu okwexeshana.
• Ukuqhawukelwa ngumphefumlo: Olu phawu luhlala luthambile kwaye ludlula.

Iziphumo ebezingalindelekanga ezinqabileyo kodwa ezimandundu

• Uxinzelelo lwegazi: Ukwehla ngokukhawuleza koxinzelelo lwegazi kunokwenzeka, ngakumbi kwabo banoxinzelelo lwegazi oluphantsi.
• IiArrhythmias: Nangona i-adenosine isetyenziselwa ukunyanga i-arrhythmias, inokubangela ngokumangalisayo ukubetha kwentliziyo entsha okanye eyahlukileyo.
• Iintshukumo Zokwalana Nezinto: Izinto ezinqabileyo kodwa eziqatha, ezifana ne-anaphylaxis, zingenzeka, ezifuna unyango olukhawulezileyo.

Ukusebenzisana namanye Amayeza

I-Adenosine inokusebenzisana namayeza athile, nto leyo enokutshintsha ukusebenza kwayo okanye yonyuse umngcipheko weziphumo ebezingalindelekanga. Kubalulekile ukwazisa umboneleli wakho wezempilo malunga nawo onke amayeza owasebenzisayo, kuquka amayeza athengiswa ngaphandle kwemvume kagqirha kunye nezongezo.

• Icaffeine kunye neTheophylline: Ezi zinto zichasene ne-adenosine kwaye zinokunciphisa ukusebenza kwe-adenosine. Kuyacetyiswa ukuba uziphephe iimveliso ezine-caffeine ngaphambi kokuba ufumane i-adenosine.
• I-Dipyridamole: Eli liyeza le-antiplatelet linokuphucula iziphumo ze-adenosine, ezinokuthi zikhokelele ekucotheni okugqithisileyo kwesantya sentliziyo.
• Carbamazepine: Isetyenziswe kunyango lokuxhuzula, i-carbamazepine inokunyusa umngcipheko we-heart block xa isetyenziswe kunye ne-adenosine.
• I-Digitalis kunye ne-Beta-Blockers: La mayeza anokwandisa umphumo we-bradycardic (isantya sentliziyo esicothayo) se-adenosine, efuna ukubeka iliso elisondeleyo.

Iinzuzo zeAdenosine

Isenzo esikhawulezayo nesisebenzayo se-Adenosine kwisantya sentliziyo yeyona nzuzo yayo iphambili, nto leyo eyenza ukuba ibaluleke kakhulu kunyango olungxamisekileyo lwentliziyo. Nazi ezinye zezibonelelo zayo eziphambili:
