Abstract

Hemorrhage to fetal tissues occurred when late-term pregnant mice were exposed to lithotripter fields of relatively low amplitude. These hemorrhages were always observed in tissues near developing bone or cartilaginous structures such as the head, limbs and ribs, while soft tissues distant from bone were relatively free of hemorrhage. Thresholds for hemorrhage in the fetus were determined for exposures of pregnant mice on the 18th day of gestation to 200 pulses from a piezoelectric lithotripter. Animals were exposed to axial peak positive pressures of either 0 (sham), 1, 2, 3, 5 or 10 MPa. Thresholds for hemorrhage to the head, limbs, ribs and lung were all <1 MPa.
