Devin ni wiki 35 mjamzito na mtoto wao wa kwanza wakati wanapoanza kueneza, vikwazo vyema kwa masaa kadhaa. Uchunguzi unaonyesha, hata hivyo, kwamba kuziba kwa kamasi kuzuia kizazi chao ni intact na kizazi bado haijaanza kupanua. Devin anashauriwa kurudi nyumbani. Kwa nini?
Janine ana mimba ya wiki 41 na mtoto wake wa kwanza anapofika kwenye kitengo cha kuzaa akiripoti kwamba anaamini kuwa amekuwa katika kazi “kwa siku” lakini kwamba “haitoi popote.” Wakati wa mtihani wa kliniki, yeye hupata vipindi vichache vya upole, kila mmoja hukaa karibu sekunde 15—20; hata hivyo, kizazi chake kinapatikana kuwa na sentimita 2 tu, na kifuko cha amniotic kina intact. Janine anakubaliwa kwenye kitengo cha kuzaliwa na infusion ya IV ya pitocin imeanza. Kwa nini?
