Ukuhlolwa kwesikhumba se-fetal pH

Ukuhlolwa kwesikhumba se-fetal scalp inqubo eyenziwayo lapho owesifazane esemsebenzini osebenzayo ukuthola ukuthi ngabe ingane ithola umoya-mpilo owenele yini.

Inqubo ithatha cishe imizuzu emihlanu. Umama ulele ngomhlane izinyawo ziyaxokozela. Uma umlomo wakhe wesibeletho uvuleke okungenani amasentimitha ama-3 kuye kwayi-4, kufakwa isigaxa sepulasitiki esithweni sangasese futhi silingane kahle nasesikhumbeni sombungu.

Isikhumba sombungu siyahlanzwa bese kuthathwa isampula encane yegazi ukuyohlolwa. Igazi liqoqwa kushubhu elincanyana. Ishubhu lithunyelwa elabhorethri yasesibhedlela noma lihlaziywa ngumshini osemnyangweni wezabasebenzi nowokulethwa kwezidingo. Kunoma ikuphi, imiphumela iyatholakala ngemizuzu embalwa nje.

Uma umlomo wesibeletho sowesifazane ungavuleki ngokwanele, ukuhlolwa akunakwenziwa.

Umhlinzeki wezokunakekelwa kwempilo uzochaza inqubo kanye nobungozi bayo. Akuhlali kukhona ifomu lokuvuma elihlukile lale nqubo ngoba izibhedlela eziningi zikubheka njengengxenye yefomu lokuvuma jikelele olisayinile lapho wamukelwa.

Inqubo kufanele izwakale njengokuhlolwa okude kwe-pelvic. Kulesi sigaba somsebenzi, abesifazane abaningi sebenayo i-anesthesia ye-epidural futhi kungenzeka bangayizwa ingcindezi yenqubo nhlobo.

Kwesinye isikhathi ukuqapha inhliziyo yomntwana akuhlinzeki ngolwazi olwanele mayelana nenhlalakahle yengane. Kulezi zimo, ukuhlola isikhumba se-pH kungasiza udokotela ukuthi anqume ukuthi ngabe umbungu uthola i-oxygen eyanele ngesikhathi sokubeletha. Lokhu kusiza ukunquma ukuthi ngabe ingane iphilile ngokwanele yini ukuthi iqhubeke nokubeletha, noma uma ukulethwa kwe-forceps noma ukuzalwa ngokuhlinzwa kungayindlela engcono kakhulu yokudiliva.

Yize ukuhlolwa kungavamile, ukulethwa okuningi akubandakanyi ukuhlolwa kwe-pH yesisu sekhanda.

Lokhu kuhlolwa akunconyelwa omama abanezifo ezifana ne-HIV / AIDS noma i-hepatitis C.

Imiphumela ejwayelekile yesampula yegazi le-fetus yile:

• I-pH ejwayelekile: 7.25 kuye ku-7.35
• Umngcele pH: 7.20 kuya ku-7.25

Izibonelo ezingenhla yizilinganiso ezijwayelekile zemiphumela yalezi zivivinyo. Ububanzi bamanani ajwayelekile bungahluka kancane phakathi kwamalabhorethri ahlukene. Amanye amalebhu asebenzisa izilinganiso ezahlukahlukene noma avivinye amasampula ahlukile. Khuluma nodokotela wakho mayelana nencazelo yemiphumela yakho ethile yokuhlolwa.

Izinga le-pH legazi lesikhumba se-fetal elingaphansi kuka-7.20 lithathwa njengelingavamile.

Ngokuvamile, i-pH ephansi iphakamisa ukuthi ingane ayinayo i-oxygen eyanele. Lokhu kungasho ukuthi ingane ayikubekezeleli ukubeletha kahle kakhulu. Imiphumela yesampuli ye-pH yesisu se-fetal scalp idinga ukuhunyushwa ngomsebenzi ngamunye. Umhlinzeki angazizwa ukuthi imiphumela isho ukuthi ingane idinga ukulethwa ngokushesha, kungaba nge-forceps noma nge-C-section.

Ukuhlolwa kwesikhumba se-fetal scalp pH kungadinga ukuphindwa izikhathi ezimbalwa phakathi nomsebenzi onzima ukuze uhlole ingane.

Izingozi zifaka okulandelayo:

• Ukopha okuqhubekayo endaweni yokubhoboza (cishe uma ingane ingalingani nge-pH)
• Ukutheleleka
• Ukulimazeka kwesikhumba somntwana
