Contact Doctor/Hospital

in order to get a referral to a specialist at the University Hospital of Göttingen (important: let the doctor mark with a cross "besondere Heilbehandlung", not "allgemeine Heilbehandlung"), please see a "Durchgangsarzt" previously. Via the homepage of the DGUV you will find a "D-Arzt" close to you:

The "D-Arzt" will forward your case officially to Göttingen:

Priv.-Doz. Dr. med. Astrid Heutelbeck,
Institute of Occupational, Social and Environmental Medicine,
Georg-August-University of Göttingen, Waldweg 37 ,
37073 Göttingen, Germany,
Fon secretary’s office (weekdays 8.00h - 16h): +49 551/39-4950
out of business hours: +49 (0)551-39-66189,

Symptoms may occur immediately or later on, they can develop over days or weeks (or not at all).

Health effects could be:

mucosa irritation, headache, abdominal cramps, muscle weakness, flu-symptoms, difficulties with balance and walking, prickling and numbness.

Long-term effects of neurotoxicity can be:

fatigue, memory dysfunction, trouble concentrating and speaking. Symptoms must be logged and supervised by a doctor continously. An event-diary with all medical results is important, therefore a detailed documentation is necessary.

Have a laboratory provide you with: 

  • complete blood count (CBC), white blood count (WBC) + Differential, liver transaminases, creatine kinase with isoenzymes.
  • blood gas analysis including CO-Hb, MET Hb and O2-saturation have to be measured as quick as possible since the half-life period of CO-Hb (Carboxyhemoglobine) is 245 minutes. Measurements on the following day might be normal again. Smoking will affect the results.
  • AChE (Acetyl-Cholin-Esterase) should be analyzed immediately and monitored within the following weeks.

Moreover, the following symptoms should be examined and documented: cardiac arrhythmia, electrocardiogram ECG, respiratory distress, neurologic deficits.

Additionally get two samples of 30ml blood (EDTA) for further testing in Göttingen (frozen, not chilled: We recommend a BChE-Test (Butyryl-Cholin-Esterase) if possible, inspite of still missing conventional standard values for comparison.

Collect 3 urine samples within the first day, then at least one per day the following days and bring them to Göttingen (urine beakers are available at pharmacies or use normal cup or bottle with lid).

All urine samples and all blood samples (taken by Durchgangs-Arzt) can be forwarded via express mail to Uniklinik Göttingen, if a consultation can‘t take place the same day, but later. Further neurological examination in GÖ is essential.
