Meconium: yintoni kunye nokuba kuthetha ntoni

Umxholo

• Yintoni uxinzelelo lomntwana
• Unyango lwenziwa njani

I-Meconium ingqamana nelindle lokuqala lomntwana, elinombala omnyama, oluhlaza, otyebileyo kunye nombala we-viscous. Ukupheliswa kwelindle lokuqala luphawu olulungileyo lokuba amathumbu omntwana asebenza ngokuchanekileyo, nangona kunjalo xa umntwana ezalwa emva kweeveki ezingama-40 zokumitha, kukho umngcipheko omkhulu wokufuna i-meconium, oko kunokukhokelela kwiingxaki ezinzulu.

I-Meconium iyasuswa kwiiyure zokuqala ezingama-24 emva kokuzalwa ngenxa yokuvuselelwa kokuncancisa kokuqala. Emva kweentsuku ezi-3 ukuya kwezi-4, utshintsho kumbala nokungaguquguquki kwesitulo kunokubonwa, nto leyo ebonisa ukuba ithumbu liyakwazi ukwenza umsebenzi walo ngokuchanekileyo. Ukuba akukho kupheliswa kwe-meconium ngaphakathi kweeyure ezingama-24, kusenokubonisa ukuphazamiseka okanye ukukhubazeka kwamathumbu, kwaye kufuneka kwenziwe olunye uvavanyo ukuqinisekisa isifo.

Yintoni uxinzelelo lomntwana

Ukubandezeleka komntwana kwenzeka xa i-meconium isuswa ngaphambi kokuba ihanjiswe kwi-amniotic fluid, edla ngokwenzeka ngenxa yotshintsho kunikezelo lweoksijini yomntwana ngeplasenta okanye ngenxa yeengxaki zomtya wesibeleko.

Ubukho be-meconium kulwelo lwe-amniotic kunye nokungazalwa kosana, kunokukhokelela kulangazelelo lolwelo ngumntwana, olunetyhefu egqithisileyo. Ukuphefumla kwe-meconium kukhokelela ekwehleni kwimveliso ye-pulmonary surfactant, engulwelo oluveliswa ngumzimba ovumela ukutshintshiselana ngerhasi okwenziwa emiphungeni, enokuthi ikhokelele ekuvukeni kwendlela yomoya kwaye, ngenxa yoko, kube nzima ukuphefumla. Ukuba umntwana akaphefumli, kukho ukungabikho kweoksijini kwingqondo, enokuthi ikhokelele kumonakalo ongenakulungiseka.

Unyango lwenziwa njani

Kanye emva kokuzalwa, ukuba kufunyaniswe ukuba umntwana akakwazi ukuziphefumlela, oogqirha basusa imfihlo emlonyeni, empumlweni nasemiphungeni kwaye banikezela nge-surfactant ukunyusa i-alveoli yemiphunga kunye nokuvumela ukutshintshiselana ngegesi. Nangona kunjalo, ukuba kukho ukulimala kwengqondo okubangelwa yi-inhalation ye-meconium, ukuxilongwa kwenziwa kuphela emva kwexesha elithile. Fumanisa ukuba yeyiphi na into esebenzayo kwi-pulmonary and how it works.
