Cardiac output was restored and the ECG returned to a narrow complex morphology with sodium of 150 mmol. Thus a bolus of 300 ml of 8.4% sodium bicarbonate was given. NPIS were contacted again and advised rapid correction of arterial pH to 7.5. Periods of arrest were getting longer and the interval between them shorter. There were four case reports describing the use of methylthioninium chloride (methylene blue) in treatment of beta-blocker toxicity Citation104107Aggarwal N. The ECG trace showed marked widening of QRS complex. In addition NPIS was contacted and advised the following-(1) 100 μl of 8.4% sodium bicarbonate to correct the acidosis, (2) an isoprenaline infusion to increase the heart rate, (3) an adrenaline (epinephrine) infusion to increase the blood pressure, (4) glucagon infusion to bypass the β block and act directly on cyclic GMP, 1 (5) intravenous fluids to ensure adequate filling.ĭespite this, the patient continued to have intermittent arrests, principally PEA (5 PEA, 1VT, 1VF). She was intubated and standard ALS guidelines were followed. This type of treatment option has recently emerged as being quite effective in treating.
