Pralidoxime in organophosphorus poisoning

High-dose pralidoxime for organophosphorus poisoning.

Pralidoxime in Acute Organophosphorus Insecticide Poisoning—A Randomised Controlled Trial

BACKGROUND Poisoning with organophosphorus (OP) insecticides is a major global public health problem, causing an estimated 200,000 deaths each year. Although the World Health Organization recommends use of pralidoxime, this antidote's effectiveness remains unclear. We aimed to determine whether the addition of pralidoxime chloride to atropine and supportive care offers benefit. METHODS AND FI...

Pralidoxime for organophosphate poisoning

From their randomised trial, Kirti Pawar and colleagues report in today’s Lancet on two pralidoxime-dosing schemes in 200 patients who had moderately severe self-poisoning with organophosphorus insecticide. After a 2-g loading dose over 30 min, half received a high-dose regimen of 1 g/h pralidoxime iodide for 48 h. The other half received a lower dose: 1 g/h every 4 h. After 48 h, the lower dos...

Continuous pralidoxime infusion versus repeated bolus injection to treat organophosphorus pesticide poisoning: a randomised controlled trial.

BACKGROUND The role of oximes for the treatment of organophosphorus pesticide poisoning has not been conclusively established. We aimed to assess the effectiveness of a constant pralidoxime infusion compared with repeated bolus doses to treat patients with moderately severe poisoning from organophosphorus pesticides. METHODS 200 patients were recruited to our single-centre, open randomised co...

Organophosphorus poisoning (acute).

INTRODUCTION Acetylcholinesterase inhibition by organophosphorus pesticides or organophosphate nerve agents can cause acute parasympathetic system dysfunction, muscle weakness, seizures, coma, and respiratory failure. Prognosis depends on the dose and relative toxicity of the specific compound, as well as pharmacokinetic factors. METHODS AND OUTCOMES We conducted a systematic review and aimed...
