Successful treatment of theophylline toxicity by upper gastrointestinal endoscopy

Theophylline toxicity: Successful management of a patient with distributive shock secondary to drug overdose

Presenting a case of acute theophylline and salbutamol overdose with distributive shock. Twenty one years old lady presented with history of consumption of 3 gram of theophylline and 40 mg of salbutamol. On admission she had altered sensorium with the systolic blood pressure of 60 mmHg, unrecordable diastolic blood pressure and heart rate of 147/min. Investigations revealed severe metabolic acidosis, hypokalemia, hypocalcemia which was managed by intravenous fluids, vasopressors, infusion of injection calcium gluconate and injection potassium chloride. As her hemodynamic status did not improve, she has been initiated on 1.5 mL/kg of lipid emulsion as bolus and then 0.5 mL/kg/h as infusion. Her hemodynamic status improved gradually and she was discharged in 24 h. Lipid emulsion had been used in local anesthetics and many tablet overdoses. In this patient timely administration of lipid emulsion resulted in early recovery of shock.

Endoscopic removal of slow release clomipramine bezoars in two cases of acute poisoning

INTRODUCTION

Acute gastroscopy is seldom advocated in cases of drug overdose. However, this intervention is sometimes recommended in cases where a pharmacobezoar of toxic tablets has formed.

CASE REPORTS

We describe two patients who were admitted after major ingestion of slow release clomipramine. In one case an abdominal x-ray was highly suspicious of a large pharmacobezoar in the stomach and in the other case a tablet conglomerate totally obstructed the oesophagus. Both conditions were successfully managed by acute gastroscopy.

DISCUSSION

There are limited and inconclusive recommendations in the literature concerning the optimal treatment of pharmacobezoars.

CONCLUSION

This article provides further evidence that slow release clomipramine may be capable of forming a radio-opaque pharmacobezoar. The clinical courses in these two cases suggest that tablet removal by gastroscopy should be considered in selected cases of drug poisoning. Suspicion of a pharmacobezoar may warrant diagnostic investigations such as imaging studies and endoscopy.
