Even after correction of electrolytes, acid base balance, bolus of magnesium sulphate (30 mg/kg) and bolus of lignocaine (1.5 mg/kg) many patients with arhythmia in both groups required cardioversion.
There was a trend of reduction in AF during drug administration but arhythmia recurred after stoppage of drug.
In Pakistan, very scarce data is available on effect of prophylactic intravenous amiodarone on post rheumatic valvular replacement arhythmias. In our study we studied the effects of an IV prophylactic bolus (5 mg/kg) dose of amiodarone on patients with rheumatic mitral valve disease (MVD) undergoing MVR.
Arhythmias after cardiac surgery are associated with increased risk of complications, length of stay and cost of care.
So the use of intravenous amiodarone as a prophylaxis to post valvular surgey arhythmias is more logical.
(14) showed that propranolol or other BB drugs could lead to quinidine-like arhyhtmias (QRS prolongation) and these arhythmias could response to intravenous bolus NaHCO3 treatment.
