Vasodilator - ntoni na? Inkcazelo iqela imithi

Vasodilation inkqubo ukunyenyiswa umaleko dystrophy eludongeni nemithambo. Ichiza ukuba indlela efanayo yesenzo kunye ukusetyenziswa ukunyanga sisifo sentliziyo kunye noxinzelelo lwegazi, ebizwa ehambelanayo kwikota - vasodilator. Yintoni na kwaye yintoni zixhobo vasodilators, cinga ngakumbi.

Overview

Ukuncipha imveliso kwentliziyo, ukuphuhlisa ukusilela intliziyo, iyazingenela inkqubo adrenergic Wayesoyika renin-angiotensin, nto leyo e-nuclear angiotensin II kunye norepinephrine. izinto Active ukuhlanganisa receptors, nto leyo ekhokelela vasoconstriction.

Isigaba sokuqala sale ukusilela intliziyo ifuna kwindlela, kuba ivumela ukugcina uxinzelelo lwegazi oyifunayo. Noko ke, ixesha elide licuthe yegazi ekhokelela kuphuhliso iinkqubo congestive emiphungeni kwaye ukunciphisa imveliso intliziyo.

Vasodilators - amachiza (uluhlu lwezihloko zingafunyanwa kwiincwadi zonyango imithi ezizodwa, kananjalo, ngezansi uluhlu indlela uthandwayo eli qela), isetyenziselwa ukwandiswa imithambo yegazi. Isiphumo uphuhliso ukusebenza iqinile. Enye okubonisa Kubalulekile ukuba olu hlobo imithi a ukukhohlela ekucebiseni komphefumlo. Kuthekani ukuba loo meko iya kunceda vasodilators? Amalungiselelo e Ukhohlokhohlo intliziyo wayedla ukwandisa izitya ivaleke.

ngezigaba amachiza

Ngokuxhomekeke zeziphi iinkalo ebhedini nemithambo abachatshazelwa surfactants, kukho amaqela amathathu vasodilators zezi:

1. lwemithambo:
   • "Hydralazine";
   • abamelene calcium.
2. lwemithambo:

• nitrate;
• sydnonimine.

vasodilators lwemithambo

vasodilator lwemithambo - ntoni na? Oku oonobangela kweziyobisi sehla ilizwi kodonga lwemithambo yegazi. Venules basabela yesimo lamanani kwezinto esebenzayo ngaphezu umthambo. Kwiimeko ezinjalo, nitrate zisetyenziswa lokuphumla imithambo ezinkulu, nande egazini, ukunciphisa umthwalo entliziyweni, yokunciphisa imfuneko engabalulekanga imfuno oksijini.

vasodilators lwemithambo - amalungiselelo (amagama, amathamo zichazwe kwi table), nto leyo zithathwa eyenzwe kuzo zonke iziyobisi antianginal. Iziphumo ebezingalindelekanga ezinqabileyo kunye elifutshane elide.

vasodilators lwemithambo

vasodilator lwemithambo - ntoni na? Le into esebenzayo arhente amayeza leyo buyasikhulula inwebu yesihlunu eludongeni yodidi oluphezulu.

Umzekelo, "Hydralazine" - ichiza elo kwandisa izinga intliziyo, ukwanda igazi kuqukuqela izintso ingqondo ukuba kukho reflex impendulo ukurhoxiswa spasm yegazi. Esetyenziswa kwiintlobo ezahlukeneyo lwegazi, ntlekele unesifo xa zidityaniswe kunye nezinye izinto.

Effects ezingalindelekanga "Hydralazine":

• cephalalgia;
• anozizi ebusweni;
• ukubonakala nokudumba;
• ukuthotywa izenzo angina;
• imeko efana systemic lupus zomzimba.

"Diazoxide" - a vasodilator, nesetyenziswa kuphela isiqabu lobunzima unesifo. Yegazi, kwandisa uxinzelelo lwegazi emva kwemizuzu 2-3. Ngaphaya koko, i-arhente ebangela aphole enamandla wesibeleko kunye namanzi nokugcinwa.

abamelene calcium - iqela vasodilators esimbaxa, equka ndlela zilandelayo:

1. "Nifedipine" - kususa a spasm iinqanawa coronary, zehlisa uxinzelelo lwegazi, kunciphisa umsebenzi izihlunu zentliziyo.
2. "Verapamil" - kunciphisa engabalulekanga contractility, kubuyisela kwakhona isingqi sentliziyo kunye noxinzelelo lwegazi.

Amalungiselelo Mixed Uhlobo

vasodilator Ukuxuba - ntoni na? Oku kuthetha esisebenza apho nokuphelisa spasm kwemithambo ngemithambo. Enye i nchumu lowunene lowu sodium nitroprusside. Indlela yokusebenza uyafana ngezithako. ulawulo efakwa beziyobisi ubangela isiphumo ngokukhawuleza kwaye womelele, kodwa zezokwexeshana.

Oku kusetyenziswa vasodilator xa kukho ukusilela acute kunye esingapheliyo intliziyo, chaza unesifo kwi imvelaphi iposi engabalulekanga, unesifo Encephalopathy iimpawu. Ukwaziswa kwemithetho ye-sodium nitroprusside kunokubangela isiyezi, intloko ebuhlungu, ilahleko osezingqondweni, isicaphucaphu, tachycardia.

ACE inhibitors - iqela kuthetha uvimba ukuyilwa angiotensin ukuguqula enzyme, ngaleyo ndlela cha ukuvelisa angiotensin II. Ngaxeshanye, kukho kuqinisela of womchamo. Ukuhlelwa ACE inhibitors isekelwe kubume yemizimba yethu:

1. Iqulethe iqela sulfhydryl:
   • "Captopril".
   • "Zefenopril".
   • "Benazepril."
2. A Iqela carboxyl:
   • "Lisinopril".
   • "Enalapril".
   • "Spirapril".
3. Phosphinyl iqela equlethe:
   • "Fosinopril".

Le imixube babe nokululutho nazimpawu kwekhono lasekhohlo ventricular, yamafutha kwemithambo carotid, pathways syndrome, microalbuminuria, fibrillation atrial, iposi engabalulekanga, nephropathy, non-seswekile.

abantwana vasodilators

Vasodilators, iziyobisi abantwana zisetyenziswa kuphela ezimbi kakhulu. Njengendlela myotropic ezisetyenziswa ngokuqhelekileyo ( "Dibazol" "Papaverine") kunye ganglionic ( "benzogeksony").

Abantwana bafumana vasodilators unyango luvo. Ezi mali ijolise ekuphuculeni kwegazi ingqondo, zisetyenziswa ngendlela komzimba 'emhlophe "kunye hydrocephalus.

Nayiphi na iyeza ukhethe ngamnye, ngokuxhomekeke kwimeko yomguli, ubungqongqo ukunyhashwa, imilo kunye ikhondo sifo. Self-iyeza ayikhuthazwa.
