The normalization of hyperreflexia has been proposed by some authorities as an indicator of adequate seizure prophylaxis in preeclamptic women receiving magnesium sulfate. To test this hypothesis the patellar reflex response was measured with a quantitative technique in 20 preeclamptic patients during their progression from subtherapeutic to therapeutic serum levels of magnesium. Patients meeting selected criteria for hyperreflexia demonstrated a 46% decrease in their reflex response. Those without initial hyperreflexia failed to demonstrate a significant decrease.
一些权威人士提出，反射亢进的正常化可作为接受硫酸镁治疗的先兆子痫妇女癫痫预防充分的指标。为了验证这一假设，采用定量技术对20例先兆子痫患者在血清镁水平从低于治疗剂量升至治疗剂量的过程中测量髌反射反应。符合反射亢进选定标准的患者反射反应下降了46%。而那些最初没有反射亢进的患者则没有出现明显下降。
