Yini i-Sodium Nitroprusside: Ukusetshenziswa, Umthamo, Imiphumela Eceleni nokuningi

I-Sodium nitroprusside iyimithi enamandla efakwa ngemithambo esetshenziswa ezibhedlela ukwehlisa ngokushesha umfutho wegazi ophezulu ngokuyingozi. Le mithi esebenza ngokushesha isebenza ngemizuzu ukukhulula izindonga zemithambo yegazi, isiza ekuvikeleni izinkinga ezingathi sína njengohlangothi noma ukuhlaselwa yinhliziyo ngesikhathi sezimo eziphuthumayo zezokwelapha.

Uzothola le mithi kuphela esibhedlela noma esikhungweni sokunakekelwa okukhulu ngaphansi kokuqashwa kwezokwelapha okuseduze. Amaqembu ezempilo ayisebenzisa lapho umfutho wegazi udinga ukwehla ngokushesha nangokuphepha, okwenza kube yithuluzi elibalulekile lokuphatha izinhlekelele ze-hypertensive.

Yini i-Sodium Nitroprusside?

I-Sodium nitroprusside iyi-vasodilator enamandla engaphansi kwesigaba semithi ebizwa ngokuthi ama-nitrate. Iza njengempushana enezinambuzane abafaka imithi esibhedlela abayixuba noketshezi olukhethekile ukudala isixazululo esifakwa ngemithambo.

Le mithi ibilokhu isindisa izimpilo emagumbini eziphuthumayo nasemakhaya okunakekelwa okukhulu amashumi eminyaka. Le mithi isebenza ngokukhipha i-nitric oxide emithanjeni yakho yegazi, okubonisa imisipha ebushelelezi ezindongeni zemithambo ukuthi iphumule futhi yande.

Ngenxa yemiphumela yayo esheshayo nenamandla, i-sodium nitroprusside idinga ukuqapha okuqhubekayo futhi inganikezwa kuphela ngomugqa we-IV esibhedlela. Ithimba lakho lezokwelapha lizobheka umfutho wakho wegazi ngokuqhubekayo ngenkathi uthola lokhu kwelashwa.

Isetshenziselwani i-Sodium Nitroprusside?

Odokotela ngokuyinhloko basebenzisa i-sodium nitroprusside ukwelapha izimo eziphuthumayo ze-hypertensive lapho umfutho wegazi ufinyelela emazingeni aphezulu ngokuyingozi. Lezi zimo zidinga ukungenelela ngokushesha ukuvimbela ukulimala kwezitho noma izinkinga ezisongela impilo.

Nazi izimo eziyinhloko lapho ithimba lakho lezokwelapha lingase lisebenzise le mithi:

• Ukuqubuka komfutho wegazi ophezulu ngemithamo yomfutho wegazi engaphezu kuka-180/120 mmHg
• Ukwehluleka kwenhliziyo okungathi sína lapho inhliziyo ilwa ukuphumpa ngempumelelo
• Ukuhlukaniswa kwe-aortic, lapho umthambo omkhulu ovela enhliziyweni uthola ukudabuka
• I-Preeclampsia ngesikhathi sokukhulelwa lapho umfutho wegazi uba phezulu ngendlela eyingozi
• Ukulawulwa komfutho wegazi ngemva kokuhlinzwa kwenhliziyo okuthile
• Ukwehla komfutho wegazi okulawulwayo ngesikhathi sokuhlinzwa okuthile

Ezimweni ezingavamile, odokotela bangasebenzisa i-sodium nitroprusside ye-pulmonary edema engathi sína noma lapho eminye imithi yomfutho wegazi ingasebenzi ngokushesha okwanele. Into ebalulekile ngaso sonke isikhathi isidingo sokuncishiswa komfutho wegazi okusheshayo, okulawulwayo ngaphansi kokuqashwa kwezokwelapha.

Isebenza Kanjani I-Sodium Nitroprusside?

I-Sodium nitroprusside ithathwa njengomuthi onamandla kakhulu osebenza ngokukhulula ngokuqondile imisipha ebushelelezi ezindongeni zemithambo yakho yegazi. Lapho umuthi ungena egazini lakho, uyachitheka futhi ukhulule i-nitric oxide, into yemvelo etshela imithambo yegazi ukuthi yande.

Cabanga ngemithambo yakho yegazi njengamashubhu engadi angakhula futhi anciphe. Lapho i-sodium nitroprusside ikhipha i-nitric oxide, kufana nokuthumela isignali kulawo "mashubhu" ukuthi aphumule futhi avuleke kabanzi, okuvumela igazi ukuthi ligeleze kalula futhi kunciphise umfutho.

Umuthi usebenza emithanjeni nasemithanjeni kuyo yonke imizimba yakho. Lesi senzo esiphindwe kabili sinciphisa umsebenzi enhliziyweni yakho ngenkathi yehlisa umfutho wegazi ngokushesha nangempumelelo.

Okuthatha lo muthi njengonamandla ikakhulukazi ukuqala kwawo okusheshayo. Ngokuvamile uzobona izinguquko zomfutho wegazi phakathi kwemizuzwana engama-30 kuya kwemi-2 yokuqala ukufakwa, yingakho ukuqapha okuqhubekayo kubalulekile.

Kufanele Ngiyithathe Kanjani I-Sodium Nitroprusside?

Awukwazi ukuthatha i-sodium nitroprusside ekhaya noma ngomlomo. Lo muthi unikezwa kuphela ngomugqa we-intravenous endaweni yasesibhedlela ochwepheshe bezempilo abaqeqeshiwe.

Iqembu lakho lezokwelapha lizofaka i-catheter ekhethekile ye-IV emthanjeni wakho, ngokuvamile engalweni yakho noma esandleni sakho. Umuthi uza ngale IV njengokuthontsa okuqhubekayo okungashintshwa ngokuya ngempendulo yengcindezi yakho yegazi.

Ngesikhathi sokwelashwa, uzoqonywa kuma-monitor alandela ingcindezi yakho yegazi, isilinganiso senhliziyo, kanye namazinga omoya-mpilo ngokuqhubekayo. Abahlengikazi bazohlola izimpawu zakho ezibalulekile njalo futhi balungise umthamo womuthi njengoba kudingeka.

Akudingeki ukhathazeke ngokudla noma ukuphuza ngenkathi uthola i-sodium nitroprusside. Kodwa-ke, iqembu lakho lezokwelapha lizophatha ukudla kwakho konke kanye nokuthatha uketshezi ngokuya ngesimo sakho esithile kanye nohlelo lokwelashwa.

Kufanele Ngiyithathe Isikhathi Esingakanani I-Sodium Nitroprusside?

I-Sodium nitroprusside ngokuvamile isetshenziselwa izikhathi ezimfushane, ngokuvamile ezisuka emahoreni ambalwa kuya ezinsukwini ezimbalwa. Isikhathi esiqondile sincike esimweni sakho esithile nokuthi ingcindezi yakho yegazi isabela kahle kangakanani ekwelashweni.

Iziguli eziningi zithola lo muthi amahora angu-24 kuya kwangu-72 ngenkathi odokotela besebenza ukuzinzisa isimo sazo. Uma ingcindezi yakho yegazi isilawulwa, iqembu lakho lezokwelapha lizokwehlisa kancane umthamo futhi likudlulisele emithini yomlomo ongayithatha ekhaya.

Ezimweni eziphuthumayo, ungase udinge kuphela umuthi amahora ambalwa. Ezimweni eziyinkimbinkimbi njengokuhluleka kwenhliziyo noma ngemva kokuhlinzwa okuthile, ukwelashwa kungase kuqhubeke izinsuku eziningana.

Iqembu lakho lezempilo ngeke liwuyeke ngokuphazima i-sodium nitroprusside. Bazokwehlisa kancane umthamo ngokuhamba kwesikhathi ukuvimbela ingcindezi yakho yegazi ukuthi ingabuyi emazingeni ayingozi.

Yiziphi Imiphumela Eceleni Ye-Sodium Nitroprusside?

Njengayo yonke imithi enamandla, i-sodium nitroprusside ingabangela imiphumela emibi, nakuba iqembu lakho lezokwelapha likulandela eduze ukuze libambe futhi liphathe noma yiziphi izinkinga ngokushesha.

Imiphumela emibi evame kakhulu ongase uyithole ihlanganisa:

• Ukuqaqamba kwekhanda ngenxa yezinguquko zemithambo yegazi
• Ukucanuzela kwenhliziyo noma ukuzwa unengqondo
• Isiyezi noma ukukhathala
• Ukushaya kwenhliziyo okusheshayo njengoba umzimba wakho uzivumelanisa
• Ukujuluka noma ukuzwa ubushushu
• Ukungazinzi noma ukukhathazeka

Le miphumela ivame ukuthuthuka njengoba umzimba wakho uzivumelanisa nomuthi futhi nomfutho wegazi lakho uzinza.

Imiphumela emibi kakhulu ingenzeka, ikakhulukazi ngemithamo yokwelashwa ende:

• Ukwehla ngokweqile komfutho wegazi okuholela ezinkingeni zezitho zomzimba
• Ubuthi be-cyanide ngenxa yokusetshenziswa isikhathi eside noma imithamo ephezulu
• Ubuthi be-Thiocyanate, ikakhulukazi ezigulini ezinzima zezinso
• I-Methemoglobinemia, isimo segazi esingavamile
• Ukucindezela okukhulu ngaphakathi ngaphakathi ekhakhazini ezimweni ezingavamile

Ithimba lakho lezokwelapha liqapha lezi zinkinga ezinzima ngokusebenzisa izivivinyo zegazi ezivamile nokuqapha okuqhubekayo. Baqeqeshwe ukubona izimpawu zokuqala zokuxwayisa futhi balungise ukwelashwa ngokufanele.

Ubani Ongafanele Athathe I-Sodium Nitroprusside?
