Abstract

|
|
Study objective:
@EN To evaluate the significance of Yamaguchi index as a predictor of outcome inpatients with acute paraquat poisoning.
@ES Design:
@EN Retrospective chart review
@ES Setting:
@EN Two University Hospital EDs
@ES Methods:
@ES We reviewed the medical records of 47 patients with acute paraquat posioning(18 survived and 29 died). The Eq1 was defined as : Eq1=[K+]x[HCO3]/0.088[Cre] mEq L+1 The patient's data were plotted as calculated Eq values (y-axis) against
interval
of
time from ingestion to admission (T)(x-axis). The study patients were divided into three groups. Group A consisted of patients with Eq1> 1500-399LogT; Group B consisted of patients with Eq1:930-399LogTpatients
with Eq1≤930-399LogT.
@ES Results:
@EN There was a significant difference among three groups (A, B and C) as far as prognosis was concerned(P<0.01). In group A all patients survived(survival rate 100%). In group B. six of 13 patients survived(survival rate 6%). In group C, none of
patients survived (survival rate 0%).
@ES Conclusion:
@EN Yamaguchi index is a signfiicant predictor of outcome in patients with acute paraquat poisoning
