Ukunikezelwa kwendawo eqhelekileyo yomntwana esiswini, intloko yesana isezantsi kwaye indlela yokuqala yokuvelisa ivela. Kodwa kwipesenti ezintathu zazo zonke izidumbu, umntwana uhlala kwisibeletho ngendlela enokuthi imilenze (umlenze wesigxina), isilwane somntwana (gluteal) okanye imilenze kunye neentambo (i-pelvic presentation) ilapha ngaphantsi kwesifuba kwaye ijikeleze ukuya emnyango wengqungquthela yomfazi.
Ukubeleka kungaphendululwa ngokwemvelo ngaphandle kweengxaki, kodwa ngokuqhelekileyo imeko ziyingozi kumama nomntwana.
Inkcazo yepelvic ye-fetus - ibangela:
- i-polyhydramnios kwaye, ngoko ke, ukwandisa umsebenzi we-fetal;
- ubukho bentambo emancinci, indawo engavumelekanga yeplacenta, ukuphuhliswa kokukhula komntwana;
- ukubonakaliswa kokungondleki, uphuhliso olungavumelekanga lwesisu;
- ukwehla kwetoni yesisu.
Indlela yokwenza inkcazo ye-pelvic?
Umgqirha uqhuba ukuvavanya kwangaphandle kwintambo ye-palpation yenxalenye enkulu ebusweni obungavumelekanga kunye nokuhambelana okuthe tye ngaphezu kokungena kwintlaka. Umqondiso we-pelvic presentation of the fetus yindawo ephezulu ye-uterus. Ukutshintshwa kwe-fetus kunokuvakala kumabhinqa aneenkcazo ze-pelvic ngaphezu kwendoda. Kwakhona, ukucacisa ukuxilongwa, khetha i-vaginal examination kunye ne-ultrasound.
Ukukhulelwa njani kwintetho ye-pelvic?
Inkambo yokukhulelwa ayifani noluhlu lokukhulelwa ngokuqhelekileyo. Ngeveki ye-32, umama ozayo uyalelwe umlinganiselo othile wokuzilolonga kwaye ucebisa ukumbathisa ibhanti eneentetho ze-pelvic.
Ukuba phambi kweeyure ezingama-37-38 umntu omncinci ongeyonto engatshintshi isikhundla sakhe, ukuzalwa kuqhutyelwa ngokuqwalasela i-pelvic presentation. Kwiintsuku eziyi-10 ukuya ngaphambi komhla wokulindela wokunikezelwa, owesifazane okhulelwe uyabhedlele esibhedlele, apho oogqirha banquma indlela yokuhambisa.
I-Biomechanism yezabasebenzi kunye neprovicvic
Esibhedlele benza isigqibo sokwenza ukuzala komntwana okanye ukuphelisa intetho yesisu.
Ngexesha elifanayo, izinto ezinjenge:
- luhlobo luni lokubeletha, ngeliphi ubudala;
- ikhosi kunye nesiphumo sokukhulelwa kwangaphambili;
- ukukhulelwa kwangoku;
- ubukho be-edema;
- ubukho bexinzelelo lwegazi eliphezulu;
- ukungasebenzi kwemfucuza;
- Isisindo esilinganiselwayo kunye nemeko yomntwana;
- ubukhulu beengcambu zomama;
- kwimeko yintoni umlomo wesibeleko, nokuba ngaba ulungele ukuzala;
- uhlobo lwe-pelvic presentation;
- isikhundla sekhanda lomntwana.
Ukuba ubunzima bebuhlungu ngexesha lokukhulelwa, lo mfazi unesilonda esincinci, ubunzima bomntwana bungaphezu kwama-3,500 amagremu, ubudala beli bhinqa lineminyaka engama-29-30 ubudala kwaye unokukhulelwa kokuqala, ngoko oogqirha abangaphezu kwama-80% amagosa agqiba kwinqanaba le-cavali.
Iziphumo zentetho ye-pelvic
- Ukuba ngaba kwenziwe isigqibo sokwenza icandelo lesaharenti, ngoko isiqhekeza sihlala kwisibeleko somfazi.
- Isimo seentsana ezizalwe kwinkcazo ye-pelvic kwiinkonzo zemvelo ayisoloko iyanelisayo. Uphuhliso olunokwenzeka lwe-hypoxia lungaphinda lubangele ukuphazamiseka kwengxaki kumntwana.
- Kukho ukutshintshwa kwe-joint hip kunye neengxaki kumama.
Kodwa ukuba zonke izilumkiso ziyadibana, abantwana bazalwa bephilile, kwaye bahluke kwabanye.
