Sábháilteacht

Cé nár chóir dóibh ocrais

Is sábháilte ocsaint do chuid is mó daoine fásta sláintiúla agus go deimhin, tá sé míchuí do mionlach ar leith. Tá sé níos tábhachtaí a fháil amach cé hiad atá tú ná an prótacal.

Cás diaibéiteas go mion

Tuillíonn sé níos mó ná sraith tábla mar is ann a gortaítear daoine. Tástáil INTERFAST-2 ocsaint eatramhach i daoine le diaibéiteas cineál 2 a chóireáil le inslin agus thuairiscigh sé ar éifeachtúlacht agus sábháilteacht [8] — is féidir é a dhéanamh, agus rinneadh é le bainistíocht cógais san áireamh sa phrótacal. Bhí trial a bhí comhoiriúnach le ocsaint eatramhach agus ithe teoranta go luath i gcomparáid le srianta calraí agus cúram caighdeánach i ndaoine atá i mbaol [7].

Fuair an mheit-anailís a bhí ag comparáid ocsaint eatramhach le srianta fuinnimh leanúnach i diaibéiteas cineál 2 torthaí comhoiriúnacha [5] — ag ciallú nach bhfuil cúis éifeachtúlachta ann chun an riosca hypoglycaemia breise a ghlacadh gan maoirseacht.

Galar itheach

Is é seo an riosca is lú a thógtar go dáiríre i gcontúirt ocsaint. Tá srianta struchtúrtha, rialacha faoi na huaireanta ceadaithe, agus an frámáil morálta a fhorbraíonn timpeall orthu gar do mheicníochtaí galar itheach srianta. Do dhuine le sin stair, nó le treocht gníomhach i dtreo timthriallta binge-srianta, d'fhéadfadh prótacal ocsaint a bheith mar an rud a athoscailt é.

Na comharthaí rabhadh atá fiú a ainmniú: stró nuair a athraíonn an fuinneog, ag éirí níos faide an fuinneog, ag comhoiriúnú le hithe le h-ocsaint breise, agus rúndacht. Má tá aon cheann de sin aithne agat, is é an hidirghníomhú ceart tacaíocht, ní prótacal difriúil.

Na fo-iarsmaí coitianta, neamh-dainséara

  • Pian cinn sa chéad seachtain nó dhó, de ghnáth ag socrú.
  • Neirbhíseacht agus droch-chomhthéacs le linn na n-uaireanta ocsaint, go háirithe go luath.
  • Constaicíon, go príomha ó laghdú ar an iomlán intake agus snáithín.
  • Codladh bocht má chríochnaíonn an fuinneog an-lá nó má tá ocsaint dian.
  • Neamhthuiscint fuar le h-ídiú fuinnimh leanúnach.

Éiríonn an chuid is mó le hoiriúnú, h-uisce agus leictreoidí cuí, agus gan an ídiú a dhéanamh go míchuí.

Surgery

Tá a comhoibriú féin ag ocsaint perioperative agus ní hé an rud céanna le h-ocsaint eatramhach. Má tá tú ag dul faoi nós imeachta, lean treoracha foireann anaestéise seachas do phrótacal.

Ceisteanna coitianta

An bhfuil troscadh sábháilte san fhadtéarma?
D'aosaigh sláintiúla, ní léiríonn na trialacha aon chomhartha buartha, ach tomhaistear na cinn is faide i míonna go cúpla bliain. Is é breith Cochrane ar chosc cardashoithíoch ná "fianaise neamhleor" [4].
An féidir liom troscadh agus mé ar mheitfoirmin?
Is annamh a chuireann meitfoirmin amháin hipeaglicéime ar fáil, mar sin tá an riosca níos ísle ná le hinslín nó sulfoinileiríos. Fós fiú é a dhearbhú le do dhochtúir oidis.
Cad faoi chlocha domlais?
Méadaíonn cailliúint mheáchain thapa ar bhealach ar bith riosca clocha domlais. Is saincheist é seo maidir le ráta cailliúna meáchain seachas ceann atá sonrach do throscadh.
Ar cheart d'aosaigh níos sine troscadh?
Le tuilleadh cúraim. Cuireann athbhreithnithe an córas cardashoithíoch atá ag dul in aois agus imní faoi mhais lom in iúl go sonrach — féach éifeachtaí meitibileacha.
