Ukulungiselela i-Dopamine: imiyalelo yokusetshenziswa

Isidakamizwa esithi "Dopamine" singokwesigaba sezidakamizwa ze-dopaminomimetic ne-adrenomimetic.

Umphumela wokwelapha wezidakamizwa "i-Dopamine"

Imiyalo yokusetshenziswa ichaza ukuthi lesi sidakamizwa yisidakamizwa ephumelelayo ye-cardiotonic kanye ne-hypertensive. Isikhathi sokwelashwa nesilinganiso sinqunywa udokotela, ukwelashwa okuzimele akuvunyelwe ngokuqinile. Ukugxila kulungiselelwe lapho isisombululo sokuphatha kwangaphakathi senziwa khona.

Ukulungiselela i-Dopamine: isilinganiso

Izinga eliphansi lifika ku-3 μg / kg / iminithi. Kulesi simo, izidakamizwa zisebenza ngokuyinhloko kwi-dopamine receptors, zijabulisa ukwandiswa kwemikhumbi ye-coronary, ye-renal, yama-mesenteric, ne-cerebral. Ngenxa yomphumela othize kwi-receptors, imithi inganciphisa ukumelana kwemikhumbi yezinso, kanye nokwandisa ukugeleza kwegazi. Inani eliphansi nelisetshenziswayo lesidakamizwa likhuthaza ama-adrenoreceptors e-postsynaptic, ngaleyo ndlela yandisa ivolumu yamaminithi amancane, ngaleyo ndlela iphumelele umphumela omuhle kakhulu. Uma usebenzisa izidakamizwa eziphezulu zezidakamizwa, ukunciphisa izitsha zezinso kwenzeka, ukwanda ku-OPSS (ukulinganisa okuphelele komzila wegazi), isilinganiso senhliziyo (isilinganiso senhliziyo). Umthelela wokwelapha kwenzeka emaminithini amahlanu emva kokuphathwa kwesisombululo.

Isibonakaliso sesidakamizwa "I-Dopamine"

Imfundo yokusetshenziswa ibonisa ukuthi i-agent ilungiselwe ukuhluleka kwenhliziyo etiology ehlukene, isifo sofuba esithathelisayo, i-postoperative, i-anaphylactic, i-cardiogenic ne- hypovolemic. Isidakamizwa sisetshenziselwa uketshezi kanye ne-hypotension ye-arterial.

Ukuqhathaniswa kwe-Dopamine

Imfundo yokusetshenziswa ixwayisa ukuthi ayivunyelwe ukuthatha ikhambi le- fibrication ye-ventricular, pheochromocytoma, hypersensitivity, hypertrophic obstructive cardiomyopathy.

Ukulungiselela i-Dopamine: imiyalelo yokusetshenziswa

Inani lemithi yokusetshenziswa lisethelwe isiguli ngasinye ngabanye. Okokuqala, umthamo uxhomeke ekubalukeleni kwengcindezi yegazi, ubunzima bokushaqeka nokuphendula ekulawulweni kwezidakamizwa. Ukwandisa i-diuresis futhi ukwandise isivumelwano sokwelapha kwe-myocardium "iDopamine" (izidakamizwa) ezijowe phansi kuya ku-250 mcg ngomzuzu. Uma kudingeka, inani le-ejenti lingakhuphuka, kodwa lingaphezulu kuka-1.5 mg ngomzuzu. Kwabantwana, ikhambi lilawulwa ngomthamo we-5 μg / kg / min. Kuzo zonke iziguli, inkambo yokwelashwa yinyanga.

Imiphumela emibi yesidakamizwa "i-Dopamine"

Imiyalo yokusetshenziswa ixwayisa ukuthi uma usebenzisa imithi, kwezinye izimo, imiphumela emibi eyenzekayo engxenyeni yezitho zokugaya zibonakaliswa yisicefe, isuka esiswini nasemathunjini, nokuhlanza. Ngaphezu kwalokho, izinqubo ze-cardiac and vascular ziphendule imithi enezincindezelo, izimpande ze-ventricular, ukungasebenzi kahle, ama-spasms, tachycardia, i-bradycardia. Imiphumela emibi ihlanganisa ukusabela kokugula, izinkinga zesimiso sezinzwa.
