[Estimation of internal hemorrhage in tubal pregnancy with ultrasonography].
OBJECTIVE
To investigate the correlation between the free fluid area detected with ultrasonography and the internal hemorrhage volume observed during operation in tubal pregnancy.


METHODS
The correlation between the size of free fluid area measured by ultrasound and the volume of internal hemorrhage collected during operation among 201 cases of tubal pregnancy was analyzed. The difference of internal hemorrhage between tubal abortion and tubal pregnant rupture was analyzed too.


RESULTS
A positive correlation was observed between the size of free fluid area measured by ultrasound and the internal hemorrhage volume (r = 0.7712). A statistically significant difference of internal hemorrhage volume was found between tubal abortion and tubal pregnant rupture with a free fluid area in the range of 0.1-10.0 cm.


CONCLUSIONS
The volume of internal hemorrhage caused by tubal pregnancy can be estimated according to the free fluid area detected with ultrasonography.
