Kuthamanga koyambirira kwa chiwalo choyamba kumayambitsa magazi, ndipo kenako, popanda chithandizo chofulumira, kupita padera. Ngati maselowa amachitikira pamphepete mwa placenta ndipo magazi amalowa pakati pa khoma ndi chiberekero, kutuluka magazi kumatanthawuza kutuluka magazi. Chizindikiro cha kutuluka m'magazi ndi kupatukana kwa magazi kwa placenta, zomwe zimachititsa hematoma. Pankhaniyi, pali chithunzi chodziwika bwino chachipatala. Magazi amalowetsa khoma la uterine, amachotsa mitsempha ya minofu, amalowa pachivundikiro chakunja kwa khoma la uterine, chifukwa chiberekero chimakhala chachilendo.
Tiyeni tiwone chomwe chimayambitsa chida cha placenta pa nthawi ya mimba?
Zimayambitsa ndi njira ya matenda
Kusintha kwa mavoti m'madera a malo otchedwa uterine amalingaliridwa ndi madokotala monga ogwira ntchito ochepa m'mayi am'tsogolo komanso poyerekeza ndi matenda a ziwiya za toxicoses, hypovitaminosis, nephritis. Madokotala amapenda kafukufuku kuti adziwe zizindikiro zomwe zimayambitsa matendawa ndipo amawona chithunzi chodziwika bwino cha chithandizo, chomwe chikuwonetsedwa ndi vuto la chiberekero (mothandizidwa, komanso kupwetekedwa kwa mwanayo). Matenda ochepa kwambiri a magazi amapezeka m'dera lalikulu mokwanira pamene pulasitiki imatha. Zizindikiro zonsezi zikuphatikizidwa ndi maonekedwe oopsya: wodwalayo akudandaula kuti mutu wake ukutuluka, akudwala, misonzi, pali ululu wopweteka m'mimba. Wodwalayo amawoneka wotumbululuka, khungu lake lili ndi thukuta lozizira, kuthamanga kuli kofulumira, kupanikizika kumakhala kochepa, kopanda phokoso.
Kodi madokotala amachitanji atapezeka kuti akusowa kwambiri pamene ali ndi mimba?
Pamene chitetezo cha placenta pa nthawi ya mimba chimachitidwa ndi mchere. Pa nthawi ya kubeleka, m'pofunika kutsegula chikhodzodzo cha fetal, chomwe nthawi zambiri chimasiya kupwetekedwa kwa pulasitiki, kufulumizitsa kuchotsa chiberekero pogwiritsira ntchito forceps kapena chipangizo chapadera chimene chimagwiritsidwa ntchito powathandiza kubereka. Pambuyo pa nthawi yoberekera, kuchotsedwa mwala kwa placenta ndi kovomerezeka, ndipo chiberekero cha uterine chimavomerezedwa kuyesedwa.
Nthawi yoyamba yobereka ingakhale yovuta chifukwa chokhala ndi magazi chifukwa cha kuchepa kwa chiberekero (atony) minofu kapena pansi pa hypo-fibrinogenemia (matenda olepheretsa magazi, gawo lachitatu). Chifukwa cha chiberekero chachikulu kwambiri mu chiberekero, madokotala amalimbikitsa gawo losungirako mankhwala, pambuyo pake pamapeto pake amachotsedwa.
Kodi mimba ikhoza kuwonongeka?
Madokotala amalimbikitsa kuti akhale ndi pakati pothandizira kuchitapo kanthu chaka chimodzi, osati kale. Panthawiyi, chiberekero cha mkazi chidzatha kubwezeretsedwa, ndipo mkaziyo adzakhalanso wokonzeka kumva chimwemwe cha kubadwa kwa moyo watsopano mwa iyemwini.
