[Severe acute buflomedil poisoning].

The severity of the acute intoxication from buflomedil, a vasodilator with papaverinic and alpha-adrenolytic effects, remains generally underestimated. We report the case of a 18-year-old girl who ingested a high amount of buflomedil. Two hours later, she developed seizures and ventricular arrhythmias. On admission to the ICU, she was in circulatory arrest followed by deep coma with mydriasis (GCS = 3). Buflomedil blood concentration, 2 hours after admission, was 97.3 mg.L-1. Toxicological screening for other drugs was negative. Therapy included external chest compressions tracheal intubation, mechanical ventilation, epinephrine and gastric lavage. The haemodynamic status improved within the first 24 h, although she remained comatose until the fifth day. She was discharged the eight day after her admission. This observation demonstrates that the potential severity of buflomedil poisoning is mainly due to early cardiac complications. Treatment remains purely supportive.

Enoximone and acute left ventricular failure during weaning from mechanical ventilation after cardiac surgery.

OBJECTIVE: To evaluate enoximone, a phosphodiesterase III inhibitor, in the treatment of left ventricular failure during the weaning of patients from mechanical ventilation after heart surgery. DESIGN: Open label, prospective, weaning trial. SETTING: Cardiothoracic surgical intensive care unit (ICU) in a university hospital. PATIENTS: Nine patients were studied after one or more unsuccessful attempts at weaning from mechanical ventilation due to left ventricular dysfunction. INTERVENTION: For each patient, two respiratory weaning attempts were studied: the first one as a control and the second one with enoximone infused at a rate of 30 micrograms/kg/min for 30 mins, then at a rate of 10 micrograms/kg/min. MEASUREMENTS AND MAIN RESULTS: Hemodynamic measurements were performed at the following interval times: baseline during mechanical ventilation; during spontaneous ventilation with a T-piece for a minimum of 10 mins; during mechanical ventilation after the enoximone infusion for 30 mins; during spontaneous ventilation for a minimum of 10 mins with an enoximone infusion running. During spontaneous ventilation, enoximone increased cardiac index by 34% but mean artery, right atrial, and pulmonary artery occlusion pressures did not change. Despite an increase in venous admixture due to augmented cardiac index and inhibition of hypoxic vasoconstriction, no oxygen debt occurred because oxygen delivery increased. Seven of nine patients were weaned successfully from mechanical ventilation. CONCLUSION: Because of its positive inotropic and vasodilatory properties, enoximone is helpful for respiratory weaning of patients with left ventricular failure after cardiac surgery.
