Ischemia yeuropi muzvitsva ndeye 60%, uye maererano nezvimwe zvinyorwa kusvika kusvika ku80% yezvose zvinokanganisa kurongeka kwenheyo. Izvo zvizhinji zvehutano hwehutachiona hunokonzerwa nekusawirirana kwezvakatipoteredza, uye nezvirwere zvevakadzi panguva yekuzvitakura, kuratidzwa kwehutachiona hwehupombwe, uye, zvinonzwisisika, kuburikidza nekubudirira kwakanyanya kwemichina yekurainita yekuyamwisa uye kukura kwekuvandudzwa kwemazuva ano. Vaya vana avo vakaurayiwa vakawana mukana wokurarama. Asi izvi hazvina kuvasunungura kubva pamigumo yezvipembenene zvepoloric, zvinokonzerwa nehutachiona hwehutachiona hwehutano kana hutachiona hwemagetsi (cerebral palsy).
Chii chinonzi ubongo ischemia?
Hypoxic-ischemic encephalopathy ine zvikamu zviviri: hypoxia uye ischemia.
- Hypoxia inogona kunge yakakonzerwa nokusadya kwakakwana kweokisijeni kumwana panguva yekuzvitakura (kupisa zvinokonzerwa nokuputsa ropa mukati maro, rambo rwonzi rwomukati kana kukanganiswa kwesimbi inemia mune amai) kana nehutano hwekufema munguva yekuberekwa.
- Ischemia inoratidzika sekutyora kwemwoyo yematambudziko. Kazhinji kazhinji izvi zvinoitika kana kune hutachiona hwemashure ekuberekwa, kuwedzera kwe acidosis, kukwana kwe electrolytes.
Nzira yakaoma yekuvhiringidza kumasero emuitiro wesheyo anotangwa. Chinhu chisingafadzi zvikuru mumamiriro ezvinhu aya ndechokuti izvi zvinogona kunonoka munguva. Chikamu che hypo hypoia kana ischemia muchechecheche chiri kure kumashure, uye kuve kwekuchinja kwechirwere kunenge kwatoitwa. Mukuwedzera, mwana wacho haana kunyatsogadzirisa zvirongwa zvekugadzirisa zvinokonzerwa nekuchengetedza kwemazuva mazhinji kwemazuva ose. Nokukurumidza zvikuru, kuparara kunowanzoitika, kunotungamirira ku cerebral edema uye inotevera necrosis kana apoptosis yemasero. Migumisiro inogona kunge isingazivikanwi zvikuru.
Kurapa kweIschemia
Kuti zvideredze migumisiro, muna 2005, purogiramu yakagamuchirwa kubatsira vana vachangobva kuberekwa neuropi ischemia "Mazano ekugadzirisa maitiro emucheche mushure mokunge asphyxia". Zvichienderana nehuwandu hwehutachiona ischemia, mitemo yakasiyana-siyana yekurapwa inopiwa.
Kuvhiringidzika kana kushungurudzwa kweCS isimboti ye ischemia yezinga rekutanga revacheche uye risingagumi kwemazuva 5-7. Nokuda kwechireji chechidimbu - mazuva anopfuura 7 nekunamatira kugumburwa, kusagadzikana kwepfungwa yepamusoro uye nhengo dzomukati. Dhigirii yakakura inotungamirira mukunyengera uye coma.
