Severe organophosphate poisoning (OPP) has a high mortality rate. Respiratory and neurological complications are common in OPP. Multiple organ distress syndrome (MODS) and renal impairment are relatively rare but correlated with death. In previous publications, in patients who did not survive OPP, their deaths were due to MODS or acute renal failure. A case of intentional ingestion of an organophosphate with renal and multiple organ complications is described. In addition to the standard atropine/oxime regimen, continuous venous-venous haemofiltration (CVVH) therapy was started; the patient survived this intoxication. The pathogenesis of renal injury by OPP is unclear and more insight is required. In our experience, CVVH can be a valid therapy, considering in particular the toxicokinetics of the organophosphate.
