Randomized Controlled Trial Comparative Study Clinical Trial
[Enoximone in postoperative "low-output syndrome"--comparison with dobutamine].
Low output syndrome sometimes complicates early postoperative states following cardiac surgery. A comparative study of hemodynamic responses to enoximone and dobutamine was carried out in two groups of 20 patients each, during a 22-24 hour postoperative observation period. Enoximone, 1 mg/kg i.v. total dose, was given in the first 20 minutes. ⋯ The enoximone group showed a diminution of systolic arterial pressure of 14% in the first 120 minutes, with a return to initial values after 22 hours. Dobutamine produced an increase in systolic arterial pressure of 23% after 2 hours, maintaining increased values of approximately 20% during the observation period. Heart rate increase slightly in both groups in a similar way.(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Clinical Trial
Comparison of the antiarrhythmic activity of mexiletine and lorcainide on ventricular arrhythmias.
In a blind cross-over study, 12 patients with ventricular arrhythmias (VPC's; Lown Grades II-IVB) resistant to a daily dose of quinidine 1.2 g, disopyramide 0.8 g, N-propyl-ajmaline 0.1 g were randomly given, each dose for one week, placebo (PL), mexiletine (MEX; 400, 600, 800 mg daily) and lorcainide (LOR; 200, 300, 400 mg daily). On the last day of each treatment period, patients were evaluated by 24-h continuous ambulatory monitoring, 6-channel surface ECG, plasma concentrations and side-effects. During PL I (before) and PL II (after drug treatment), the mean number of VPCs per hour was 670 and 701. ⋯ Vomiting, nausea, and abdominal pain were seen in 2 patients with MEX; insomnia and feeling heat in 10 patients with LOR. At the end of the LOR-treatment, these side-effects were less in 5 and absent in 5 patients. In this study, LOR seems superior to MEX in refractory ventricular arrhythmias.
