Abstract

Background: Arrhythmia, postoperative pain and agitation are a common complication after heart surgery and are a major source of morbidity and mortality. Aims: This study aimed to study the efficacy of magnesium sulfate (MgSO 4) for reduction of post cardiac surgery arrhythmia, postoperative pain and agitation. Setting and Design: This study design was a prospective randomized controlled double blinded clinical study. Patients and Methods: 140 adult patients that underwent elective cardiac surgery were randomized into 2 groups, Mg group (group magnesium), 70 patients received 30 mg.kg-1 MgSO 4 in 500 cc normal saline and in group C (control group), 70 patients received 500 cc normal saline alone.
