Calcium chloride. imfundo

Calcium chloride inikeza eyinhloko ubuqotho nemisebenzi yokusetshenziswa izinhlelo sezinzwa futhi kwemisipha, ngoba nethonya elikhulu excitability ihlule. Calcium luyadingeka evamile umsebenzi zenhliziyo ehilelekile igazi ekunqandeni. Ngo 10 ml 10% i-calcium chloride equkethwe 1 g CaCl2 noma 273 mg-calcium zokucathula (Ca2 +). Lo sawoti calcium ka hydrochloric acid inegama calcium chloride. Kwezokwelapha, isetshenziswa njengendlela ejenti hemostatic (I-emathunjini, iphaphu, lesizalo ukopha, acinene noma ngaphambi kokuba uhlinzwe). Kuyindlela yokuvimbela ubuthi oxalic acid nosawoti yalo, nosawoti magnesium, nosawoti of hydrofluoric acid. Lihambisana nezinye izidakamizwa nezindlela-calcium chloride isetshenziselwa ukugqugquzela zabasebenzi. Lapho ufika lokuhlushwa ezithile anezakhi isisu.

Kuye ubunjalo udokotela isifo nezinkinga utjho izidakamizwa ukwelashwa ezifana calcium chloride. isicelo wayo ungaba setemlomo (ngomlomo), by electrophoresis ngaphansi kwesikhumba (i kagesi), kodwa ngokuvamile ngesimo umjovo emthanjeni. isingeniso Strong noma okusheshayo ayilungile yesixazululo kungadala necrosis ukubandlululwa. Lapho wethula ikhambi ku imisipha, umthambo noma phansi kwesikhumba ingozi contact ngephutha nge kwezicubu perivascular. Uma kwakuba khona kokuziphatha perivascular, uvo the izidakamizwa kumele kunqanyulwe ngokushesha. Kukhona ingozi kokuziphatha wendawo (ekuqongeleleni izinhlayiya noma izinto emisipheni, engesiyo ingxenye evamile zabo).

Lapho ebonisa indlela lo izidakamizwa kumelwe ngokucophelela ukufeza zonke izidingo, amiswa ku-calcium chloride kufundiswe. Too okusheshayo umjovo emthanjeni isixazululo noma ukweqisa izidakamizwa kungaholela nemiphumela emibi ehambisana ne-umsebenzi inhliziyo, kuhlanganise arrhythmia, bradycardia, futhi ventricular fibrillation. Overdosing kungaba avuse hypercalcemia ezinzima (isib ikhoma, isicanucanu nokuhlanza, ukucobeka, ezingeni kakhulu anda of calcium-plasma, ukufa okuzumayo, ubuthakathaka).

Izimpawu: ekwelapheni hypocalcemia (calcium ukuntula emzimbeni), i-magnesium ukudakwa ngenxa yokweqisa magnesium sulfate, e yokusiza umuntu ukuba aphefumule inhliziyo lapho adrenaline akekho obengaba ngcono umsebenzi inhliziyo futhi kukhona infarction ababuthakathaka noma ukungasebenzi kahle. Futhi ukulapha adjunctive kubonisa calcium chloride. Imiyalelo abonisa izimo ezahlukene (lapho calcium chloride isetshenziswa lihambisana namanye izidakamizwa), ezifana ukulunywa yizinambuzane, ngozwelo ukusabela (ikakhulukazi uma izimpawu ejwayelekile ka urticaria uzwakalise). Ingasetshenziselwa njengenhlangano adjunct ekwelapheni ukucindezeleka ngenxa yokweqisa magnesium sulfate, kanye ekwelapheni izimpawu acute kuholele colic.

izinkinga ezingathi sína kakhulu futhi kungenzeka ukusabela ezingezinhle lapho kahle calcium chloride. Manual kubonisa ukungasebenzi okungenzeka esimiso senhliziyo nemithambo yegazi (hypotension, nakwisyncope inhliziyo), ngenxa iziyaluyalu isimiso sezinzwa esiyinhloko kunomuzwa lokucindezelwa. Ungase uthole i-calcium ukunambitheka emlonyeni, uzizwa ukushisa nokunsonsotha. izinyathelo ezikhethekile ayadingeka ngesikhathi sokukhulelwa futhi ngesikhathi ukuncelisa nosana.

Ezigulini bezempilo, ezisetshenziswa ekwelapheni calcium chloride, isitatimende iqukethe isixwayiso ekhethekile aqaphe lapho uyisebenzisa. Mhlawumbe iconsi ngokulinganisela wegazi ngenxa vasodilatation (emangala mafutha anciphisa isikhala esingaphakathi isitsha kanye adhesion ngenxa ukukhululwa histamine futhi heparin) ngesikhathi umjovo. Ukusetshenziswa Its akuyona efiselekayo ekwelapheni hypocalcemia, esingamahlalakhona kwezinso. Ukusetshenziswa kwe-calcium chloride kuyinto engathandeki in iziguli esingamahlalakhona kwemigudu yokuphefumula noma ukumelwa lactic zokuphefumula ngenxa ikhono ngiphendukele usawoti acid.
