Uvavanyo lwe-pH yesikhumba se-Fetal

Uvavanyo lwe-pH yovavanyo lwe-scalp scalp yinkqubo eyenziwayo xa umntu wasetyhini esebenza nzima ukumisela ukuba ngaba umntwana ufumana ioksijini eyaneleyo.

Inkqubo ithatha malunga nemizuzu emi-5. Umama ulele ngomqolo iinyawo zakhe zixubekile. Ukuba umlomo wakhe wesibeleko uye wancipha ubuncinci iisentimitha ezi-3 ukuya kwezi-4, kufakwa ikhowuni yeplastiki kwilungu lobufazi kwaye ilingane kakuhle nentloko yokhokho olungekazalwa.

Ukhakhayi olungekazalwa lucociwe kwaye isampulu yegazi encinci iyathathwa ukuze ihlolwe. Igazi liqokelelwa kumbhobho omncinci. Umbhobho uthunyelwa kwibhubhoratri yesibhedlele okanye uhlalutye ngomatshini kwisebe lezabasebenzi kunye nokuhanjiswa. Nokuba kunjalo, iziphumo ziyafumaneka kwimizuzu nje embalwa.

Ukuba umlomo wesibeleko womfazi awukhulanga ngokwaneleyo, uvavanyo alunakwenziwa.

Umboneleli wezempilo uya kuchaza inkqubo kunye nobungozi bayo. Akusoloko kukho ifom yemvume eyahlukileyo yale nkqubo kuba izibhedlele ezininzi ziyithatha njengenxalenye yefom yemvume jikelele oyisayinileyo xa usamkelwa.

Inkqubo kufuneka izive ngathi luvavanyo lwe-pelvic ende. Kule nqanaba labasebenzi, uninzi lwabasetyhini sele benayo i-anesthesia ye-epidural kwaye abanakuziva uxinzelelo lwenkqubo kwaphela.

Ngamanye amaxesha ukubeka esweni kwentliziyo yomntwana akunikezi ulwazi olwaneleyo malunga nokuphila komntwana. Kwezi meko, ukuvavanywa kwe-scalp pH kunokunceda ugqirha ukuba athathe isigqibo sokuba ingaba umntwana sele efumana ioksijini eyaneleyo ngexesha lomsebenzi. Oku kunceda ukufumanisa ukuba ngaba umntwana uphilile ngokwaneleyo ukuba aqhubeke nomsebenzi, okanye ukuba ukuhanjiswa kwe-forceps okanye ukuzalwa kwe-cesarean kunokuba yeyona ndlela ilungileyo yokuhambisa.

Nangona uvavanyo lungaqhelekanga, ukuhanjiswa okuninzi akubandakanyi kuvavanyo lwe-pH yosana olungekazalwa.

Olu vavanyo alukhuthazwa koomama abanezifo ezifana ne-HIV / AIDS okanye i-hepatitis C.

Iziphumo eziqhelekileyo zesampulu yegazi olungekazalwa zezi:

• I-pH eqhelekileyo: 7.25 ukuya ku-7.35
• Umda pH: 7.20 ukuya ku-7.25

Imizekelo engentla yimilinganiselo eqhelekileyo yeziphumo zolu vavanyo. Amaxabiso esiqhelo ahluka kancinci phakathi kweelebhu ezahlukeneyo. Ezinye iilebhu zisebenzisa imilinganiselo eyahlukeneyo okanye ukuvavanya iisampulu ezahlukeneyo. Thetha nogqirha wakho malunga nentsingiselo yeziphumo zakho zovavanyo.

Inqanaba le-pH yegazi lomntwana elingaphantsi komntwana elingaphantsi kwe-7.20 lithathwa njengengaqhelekanga.

Ngokubanzi, i-pH esezantsi iphakamisa ukuba umntwana akanayo i-oxygen eyaneleyo. Oku kunokuthetha ukuba umntwana akawunyamezeli umsebenzi kakuhle. Iziphumo zesampulu ye-pH yesibeleko se-fetal efuna ukutolikwa ngomsebenzi ngamnye. Umboneleli unokuziva ngathi iziphumo zithetha ukuba umntwana kufuneka ahanjiswe ngokukhawuleza, nokuba kungokunyanzelwa okanye ngecandelo le-C.

Ukuvavanywa kwe-pH yesikhumba se-Fetal kunokufuna ukuphindwaphindwa amaxesha ambalwa ngexesha lomsebenzi onzima ukugcina ujonga umntwana.

Iingozi zibandakanya oku kulandelayo:

• Ukuqhubeka kokopha kwindawo yokuhlatywa (kunokwenzeka ukuba umntwana unengxaki yokungalingani kwe-pH)
• Usulelo
• Ukutyunyuzwa kwentloko yomntwana
