Methylene blue: kukanganisa zviyereso zveokisijeni neongororo dzeweti

Hongu. Methylene blue inogona kukanganisa zviyereso zveokisijeni zvinonzi pulse oximeter, zvimiti zvekuongorora weti nemimwe michina yekuongorora yerabhoritari. Kukanganisa uku kunoenderana nenzira yekuyera, kuwanda kwedhayi musampuli uye nguva yekuyera. Hazvirevi kuti mugumisiro wose usiri wenguva dzose mushure mekusangana nayo ndewenhema.

Chiyero chinoratidza okisijeni shoma chichiri kuda kutarisirwa. Tsvaga rubatsiro rwechimbichimbi kana uchinetseka zvikuru kufema, uchirwadziwa muchipfuva, uchivhiringidzika pfungwa, uchifenda kana miromo yako yava nebhuruu rakasanganiswa negireyi. Kurumidza kubata nyanzvi yezveutano kana chiyero chiri pasi zvisingatarisirwi kana chichiramba chichidzika, kunyange uchinzwa wakagwinya. Mazano eFDA pamusoro pezviyereso zveokisijeni anosimbisa kuti zviratidzo nezviyero zvinofanira kutariswa pamwe chete, uye kuti okisijeni shoma inogona kuvapo pasina zviratidzo zviri pachena. Udza vari kukurapa nezvekusangana kwako nemethylene blue; usamirira kuti dhayi ibude mumuviri usati watsvaga rubatsiro.

Machinjiro anoita dhayi chiyero

Ongororo inoshandisa chiedza inoona chiedza, yozoshandura chiratidzo ichocho kuita mugumisiro unobata zvemumuviri. Kana chimwe chinhu chinotora chiedza chikapinda musampuli, kushandura uku kunogona kusava kwakarurama. Mudziyo unogona kuratidza chiyero chakarerekera kudivi risiri iro, kuzivisa kukanganisa kana kutadza kuverenga mugumisiro.

Pakuyera okisijeni nepulse oximeter, SpO₂ inoratidzwa inofungidzira kuzara kwehemoglobin neokisijeni kubva pachiedza chinopfuura nemunyama wemuviri. Ongororo yaGorman naShnider pamusoro pekutorwa kwechiedza nehemoglobin nedhayi yakaratidza kuti methylene blue inotora chiedza chakakwana pa660 nm kuti iite sokunge kuzara neokisijeni kwaderera. Izvi zvinotsanangura chiyero chenhema chakaderera mushure mekupiwa nemutsinga: kutorwa kwechiedza kwakawedzera kunogona kufungidzirwa zvisirizvo sechinjo muokisijeni yakasungwa nehemoglobin.

Chimuti chekuongorora weti chine dambudziko rakasiyana. Nzvimbo dzacho dzine makemikari ekuongorora dzinobudisa mavara anodudzirwa nemunhu kana nemuchina. Weti ine ruvara rwakasimba inogona kuviga kana kuchinja chiratidzo ichocho chinoonekwa. Hapana pane idzi nzira mbiri inoda kuti chinhu chemumuviri chiri kuyerwa chinenge chachinja. Asiwo, hapana pane idzi nzira mbiri inodzivisa chirwere chaicho kuvapo panguva imwe chete.

Tafura yekutarisa kukanganiswa kweongororo

Tafura iyi inopatsanura yambiro dziri pamapepa echigadzirwa, mushumo wemurwere uye zviedzo zvakawedzera dhayi zvakananga mumasampuli. Kuwanda kunotaurwa ndekwedhayi musampuli yakaongororwa, kwete huwandu hwekushandisa kana mwero muropa unofungidzirwa kubva pane zvakanyorwa pabhodhoro.

Zviyero zveokisijeni zvinopindura mibvunzo yakasiyana

Sampuli yeropa rinobva mutsinga inotakura ropa kubva pamwoyo inobatsira chete kana boka rinorapa richiziva kuti chii chiri kuyerwa. Co-oximetry inoshandisa chiedza chine urefu hwemasaisai hwakasiyana-siyana kusiyanisa marudzi ehemoglobin, kusanganisira methemoglobin. Yakasiyana nechiyereso chemunwe chinowanzoshandisa urefu hwemasaisai huviri. Kuzara neokisijeni kunoverengwa uye chikamu chehemoglobin chinoyerwa zvakananga zvinobudisawo migumisiro yakasiyana. Kuongorora kwerabhoritari nyaya mbiri dzemethemoglobinemia kunotsanangura kuti kuverenga kuzara neokisijeni kubva pazviyero zvemagasi eropa kunofungidzira kuti hemoglobin iri kushanda sezvainofanira. Kuverenga kwakadaro kunogona kutsausa kana paine marudzi ehemoglobin asiri enguva dzose.

Ongororo yekurapa pamusoro pemigumisiro yeco-oximeter isingawirirani inoratidza kukosha kweizvi. Kukanganisa kwayo kwakabva kusulfhemoglobin, kwete kumethylene blue. Michina yakasiyana yakabudisa zviyero zvisingawirirani, ukuwo murwere aine matambudziko eropa chaiwo. Vaongorori vakaenzanisa nzira nezvakawanikwa pakurapa pane kuti vataure kuti murwere kana mugumisiro wose werabhoritari “zvaiva zvenguva dzose.” Musimboti iwoyo wekuongorora chirwere unoshandawo kana dhayi yakapiwa ichifungidzirwa kuti ndiyo inokanganisa.

Methemoglobinemia kukanganisika chaiko kwekutakurwa kweokisijeni, kwete kungova neropa rine ruvara rusina kujairika. Kumurwere ari kurapwa, kuderera kunoratidzwa nechiyereso kungaratidza kukanganisa kunokonzerwa nedhayi, chirwere chichiripo kana rimwe dambudziko. Boka rinorapa rinofanira kusiyanisa mikana iyi. Pepa remethylene blue rinotsanangurawo kupererwa neropa chaiko kunokonzerwa nekuparara kwemasero matsvuku eropa uye mukana wekudzoka kwemethemoglobinemia. Shanduko idzodzo dzemumuviri hadzifaniri kungonzi kukanganisa kunokonzerwa neruvara.

Kushandisa nemuromo kunokonzera dambudziko rimwe chete here?

Yambiro yakasimba zvikuru pamusoro pepulse oximeter yataurwa pano ine chekuita nekupinzwa nemutsinga. Haipi nguva inotarisirwa kana kukanganisa kunotarisirwa pakuyera kuzara neokisijeni kana vatengi vachishandisa nemuromo. Kusangana nayo nemuromo kunogona kuramba kuine chekuita neongororo dzeweti: nyaya yakabudiswa pamusoro peProsed DS yakatorwa nemuromo, mushonga wakasanganiswa une methylene blue, yakanyora nezveweti yebhuruu rakasanganiswa negirini uye yakatsanangura kuti kuchinja kweruvara kunoomesa sei kushandiswa kwezvimiti zvinoyera neruvara.

Nzira yekupiwa inokosha nokuti inokanganisa kuti dhayi inosvika sei uye rini muropa nemuweti. Saka zvigadzirwa zvemajekiseni zvinoshandiswa pakurapa zvinofanira kusiyaniswa nezvigadzirwa zvinoshandiswa nemuromo pakutsanangura kusangana nedhayi. Kuti “Ndakashandisa methylene blue” hakubatsiri sezvinoita zita rechigadzirwa, kuwanda kwayo mumusanganiswa, huwandu hwakashandiswa, nzira nenguva.

Mumanyuko aya hamuna nguva imwe chete yekumirira inotsigirwa nehumbowo inoita kuti ongororo dzose dzivimbike zvakare. Muganhu wekuwanda mudhayi musampuli haugoni kushandurwa kuva maawa kubva pakushandisa pasina rumwe ruzivo. Kuchinja kweruvara rweweti kunoonekwa hakugoniwo kuratidza kana imwe ongororo yakati ichivimbika.

Zvaunofanira kuudza nyanzvi yekurapa kana rabhoritari

Usati waitwa ongororo yakarongwa, ipa nyanzvi yekurapa yakakumbira ongororo kana rabhoritari ruzivo runotevera:

Chigadzirwa chaicho kana mufananidzo wezvakanyorwa pachiri, kusanganisira zvimwe zvinhu zviri machiri.
Huwandu hwakashandiswa, kuwanda kwacho mumusanganiswa, nzira nenguva yawakapedzisira kusangana nacho.
Zviratidzo zvipi nezvipi zvauinazvo iye zvino nechikonzero chekuongororwa.
Mugumisiro upi nezvipi usingatarisirwi, kusanganisira zita remudziyo nenguva yekuyera kana zvichizivikanwa.

Usarega kurapwa kwawakarongerwa kana kunonotsa ongororo yechimbichimbi kuti sampuli iite seyenguva dzose. Boka rinorapa rinogona kusarudza kana richifanira kuwedzera mashoko ekududzira mugumisiro, kushandisa imwe nzira yakasimbiswa kuti yakarurama kana kudzokorora kuyera pazvinenge zvakakodzera. Kungodzokorora nzira imwe chete yakakanganiswa pakarepo kungangodzokororawo kukanganisa kwayo.

Kuvaongorori, mubvunzo unoenderana neizvi ndewekuti dhayi yakachinja zvaiitika mumuviri here kana kuti yakangochinja chiratidzo cheongororo chete. Izvozvo zvinoda zviyedzo zvekuenzanisa zvinotarisa kukanganisa kwemethylene blue muzviedzo. Kuvarwere, chinobatsira kupa ruzivo rwakarurama rwekusangana nedhayi, kuitira kuti rabhoritari iongorore chiyero chakakodzera pane kungofungidzira kubva paruvara chete.
