What Should We Do After Acute Organophosphorus Pesticide Poisoning During Pregnancy?

A 25-year-old married primigravida was admitted to Pingjin Hospital after ingestion of dichlorvos, with suicidal intent. The initial serum dichlorvos level was 1.7 umol/L, with a reduction in cholinesterase activity of 29% in whole blood. Abdominal investigation revealed a soft abdomen with a pregnant uterus consistent with 9th week of gestation on echography and with a viable fetus. The patient was discharged from hospital with successful treatment of both mother and neonate after 10 days of treatment. However, we cannot confirm whether dichlorvos poisoning will affect the brain development of the fetus. Subsequently, she made an artificial abortion for fear of adverse fetal outcome four weeks later after intoxication.
