The hemodynamic effects of a 10 mg bolus of edrophonium chloride followed by a continuous infusion of 0.25 to 1.0 mg per minute, were determined in unanesthetized patients with significant myocardial disease. The effect on heart rate of the drug was negated by studying a group of nine patients with complete heart block and permanently implanted ventricular pacemakers. After the 10 mg bolus, two of the nine patients experienced dizziness, nausea and abdominal cramps associated with a mild decrease in peripheral vascular resistance. There was no significant change in cardiac index, mean blood pressure, brachial artery upstroke time, corrected ejection time, or left ventricular systolic ejection time. This study demonstrated that the continuous infusion of 0.25 to 1.0 mg per minute of edrophonium chloride following a 10 mg loading dose, had no significant effect on myocardial function.

Medication errors are probably more common in neonates than is generally appreciated. In Mexican pediatric hospitals, L-carnitine is mainly used for nutritional support and to treat cardiomyopathy secondary to neonatal asphyxia. Using a longitudinal-retrospective approach we assessed the appropriateness of all L-carnitine prescriptions written during a 12-month period at a NICU of a second-level hospital located in Toluca, Mexico. Reports of adverse reactions possibly related to L-carnitine therapy were collected and characterized. Overall, administration of L-carnitine was considered justified and appropriate only in 18% of patients. 60.7% of L-carnitine prescriptions were rated as inappropriate because the prescribed doses fell outside the recommendations. The overall rate of ADRs calculated from the patient population was 18.03%. All of them were of gastrointestinal type: abdominal cramps (8 cases, 61.54%) and vomiting (5 cases, 38.46%). Our results supported the establishment of an L-carnitine rational use policy at the NICU of the hospital under study.
