Very unusual case of 2-4 dimethylamine poisoning as a suicidal attempt.
50 year female with alleged history of ingestion of 2-4 dimethylamnie solution at her home as a suicidal attempt , came in emmergency with laboured breathing, hypoxia, bradycardia, hypotension, ECG shows ST-T changes and drowsiness
Pt admitted in icu after resuscitation with adrenalin and ET intubation , her initial ventilator requirement on controlled mode was high with PEEP of 10 and 100% FiO2 , high ionotropic support with noradrenalin and vasopressin , CXR was S/O pulmonary Oedema or ARDS , 2dEcho was global LV hypokinesia with EF of 35-40% ? Myocarditis.ABG shows hypoxia and metabolic acidosis, blood reports are grossly normal , acetylecholinestease normal
she was completely knock down with sedatives and ventilated for 24 hour, forced alkaline dieresis was started and one session of dialysis was done and other supportive measures were given.
On 2 nd day in ICU her CXR shows improvement , hypoxia improved , passed good amount of ursine with negative balance , neurologically she was concious and oriented , decreased ventilators support and gradually put on CPAP, ionotropic support decreased
On 3 rd day in ICU she was extrubated and off O2 support , off ionotrops, CXR much better and pt was mobilised.
2-4 DIMETHYAMINE is a selective and systemic post-emergence herbicide used to control annual and perennial broad-leaved weeds in a range of crops.Not an organophosphate compound
which is available as water based solution causes vomiting, congestion, pulmonary emphysema, CNS congestion, perivascular hemorrhages, severe degeneration of ganglion cells, and death within hours of ingestion
No any specific antidote is available , only supportive treatment of complication
Very few literature is available showing the effective role of forced alkaline diuresis which increases its renal elimination and some role of hemodialysis.
This patient responded very well both the measures.
