TEAC findings support humoral dominance in toxemic hypertension; leaves open whether autonomic testing informs modern preeclampsia management.
Does tetraethylammonium chloride (TEAC) reveal differences in neurogenic versus humoral blood pressure maintenance in normal and toxemic pregnancy?
Autonomic blockade with TEAC demonstrates that blood pressure in normal term pregnancy is predominantly maintained by neurogenic tone, whereas the hypertension of toxemia is largely supported by humoral factors.
Brust et al. (1948) studied this question.
