What is the coma score for amitriptyline?
A 28 year-old woman with a history of depression is brought to the emergency department approximately one hour after an overdose of amitriptyline. She is somnolent with a Glasgow coma score (GCS) of 8. Her blood pressure is 90 mm Hg by palpation and her heart rate is 110 beats/min. She undergoes immediate endotracheal intubation with moderate hyperventilation, and receives a 2 liters bolus of normal saline. Fifty grams of activated charcoal are instilled by NG tube into the stomach. An EKG shows sinus tachycardia with wide ventricular complexes (QRS interval > 160 msec) with a prominent R wave in lead aVR. Intravenous fluids and norepinephrine are administered for hypotension. Sodium bicarbonate is administered as a bolus of 1 mEq/kg and a repeat EKG reveals narrowing of the QRS complexes. However, ten minutes later the QRS abnormalities recur. Over the course of the next several hours, the patient receives ten ampules of sodium bicarbonate. Her arterial pH increases to greater than 7.50 but her QRS complexes remain narrow and she does not develop any more dysrhythmias. After 36 hours the patient is extubated and is awake and alert with resolution of hypotension. She is discharged to the psychiatry service.

The EKG can be an important indicator of the presence of sodium channel blocking drugs. Typical EKG findings include prolonged QRS duration, prolonged QT duration, or ventricular dysrhythmias. In addition, …
Diagnosis
- Patients presenting with ventricular dysrhythmias, wide QRS complexes, or severe hypotension should be suspected of poisoning by a sodium channel antagonist. Some of these agents, such as cocaine or diphenhydramine, may show up on rapid toxicology screening or gas chromatography confirmation, but this will only confirm presence of the drug. Laboratory test fo…
Treatment
- The dosage and administration of sodium bicarbonate depends on clinical indications. When sodium bicarbonate is administered for sodium channel antagonists, we recommend the use of intermittent boluses of 1-2 mEq/kg titrated to clinical effect (narrowing of the QRS interval and improvement of blood pressure). Generally, the target for serum pH is 7.4 – 7.5. While some hav…
