(1) most women can accurately recognize fetal movements
(2) cessation of movements is usually followed by fetal death within 24 hours.

(1) false positive assessment can occur if maternal pulse taken
Examination of Fetus
Grade of Maceration |
Features |
Duration of Intrauterine Demise |
0 |
• "parboiled" reddened skin |
< 8 hours |
I |
• skin slippage and peeling |
> 8 hours |
II |
• extensive skin peeling • red serous effusions in chest and abdomen due to hemoglobin staining |
2-7 days |
III |
• liver yellow-brown • turbid effusion • may be mummified |
>= 8 days |
Additional datings:
(1) bullae in epidermis (leading to peeling): appear at about 24 hours
(2) hemoglobin staining of internal viscera (loss of normal color): 24-48 hours
(3) separation of dura from calvarium bone: 5+ days
Limitations:
• Very edematous liveborn infants can have skin peeling.
