Astanga Hrudaya
छिन्द्याद्गर्भं न जीवन्तं मातरं स हि मारयेत्। सहात्मना, न चोपेक्ष्यः क्षणमप्यस्तजीवितः॥३७॥
Importance of immediate extraction of the dead fetus: The dead fetus should be cut (and pulled out quickly), because along with it, it will kill the mother also; even a second should not be ignored after its death.
