Approach Considerations

the workup for suspected organophosphate toxicity in a pediatric patient includes the following:

  • Obtain a complete blood cell count (CBC) to rule out infectious causes.

  • Chemistry tests may be useful in ruling out electrolyte disturbances.

  • Red blood cell (RBC) cholinesterase tests may reveal decreased activity, which confirms the diagnosis

  • Chest radiography may be performed to evaluate pulmonary edema.

  • Nonenhanced head computed tomography (CT) scanning may be required to assess structural lesions if the patient has an altered mental status.

  • Perform an electrocardiogram (ECG) to evaluate for cardiac arrhythmias.
