Ikebuchi et al reported a score for predicting mortality in a patient who has ingested paraquat. This can help to identify a patient who may require more aggressive management. The authors are from Tottori University of Medicine in Yonago, Japan.
Patient selection: paraquat ingestion
Parameters:
(1) number of hours since ingestion
(2) plasma paraquat concentration in µg/mL
discriminant function =
= 1.3114 - (0.1617 * LN(hours)) - (0.5408 * LN(plasma concentration))
Interpretation:
• A discriminant function result > 0.1 indicates survival.
• A discriminant function result < 0.1 indicates mortality.
