OBSTETRICS : THE LOSS OF SMALL PARTS OF THE FETUS - etiology, pathogenesis, symptoms and course of, recognition, prediction and prevention
The loss of small parts of the fetus (if the head previa).
The small size of the fetus, multiple pregnancy, high water, high above the entrance to the pelvis movable head, a narrow pelvis. There are previa, when small parts are located immediately above the unopened shells membranes, and loss, when in the mouth of the uterus are small pieces next to or in front of the head of the fetus.
Loss of legs in cases of abnormal presentations is found only rarely, mostly when immature and materialindex fruits. More common drop handles, which can lead to complications during childbirth - the extension of the head, the wrong insertion, low transverse position, stopping the translational movement of the fetus and other consequences associated with artificial narrowing of the entrance to the pelvis.
Internal, mainly vaginal examination, especially after ruptured membranes.
With extensive pelvis, especially in nagaragawa, often spontaneous labor without complications. When the mobile head - to fill the pen. When the movable cylinder, and insufficient opening of the throat to fill the handle and enter metratester to prevent re-deposition of the handle. With the full opening, the movable fruit, just ceded waters and the failure of attempts to set the knob - turn the fruit and extract. If the head after reset handle was fixed at the entrance of the pelvis, the pathology can be considered resolved. When the head is in the cavity and the outlet of the pelvis and discontinued translational movement of the fruit - grasping forceps. When failure or a dead fetus - craniotomy.
The loss of small parts in a transverse position and pelvic previa see the position of the fruit of the cross.
