Case Reports
Superwarfarin and glass ingestion with prolonged coagulopathy requiring high-dose vitamin K1 therapy.
A 23-year-old man was brought to the emergency department after eating four boxes of brodifacoum-containing rodenticide over a 4-day interval and pieces from approximately two bottles of glass over the previous 2 weeks. He was asymptomatic but his prothrombin time was markedly elevated with an international normalized ratio (INR) of 37.8. A plain abdominal film showed diffuse radiopaque foreign bodies, presumably glass, in the large and distal small intestines. ⋯ At 5-month follow he was doing well. Compliance with large daily doses of vitamin K1 for treatment of "superwarfarin" ingestion may be poor because of the duration of treatment and large number of pills required. A more concentrated formulation may be advantageous for management of patients with brodifacoum poisoning.

The bispectral index (BIS), a processed variable derived from the raw electroencephalogram (EEG) used to guide sedation in the intensive care unit (ICU), has not been tested during barbiturate therapy for elevated intracranial pressure. We determined the BIS and suppression ratio (SR) values during traditional burst monitoring of the raw EEG during pentobarbital infusions. ⋯ The Aspect A-1050 applied to patients and monitored by nurses and physicians works well as a bedside EEG monitor, providing a raw EEG signal to titrate barbiturate therapy. The continuous data trend and real-time digital output for the BIS and SR quantify the degree of EEG suppression well and may prove helpful in facilitating titration of barbiturate infusions.
