Randomized Controlled Trial Comparative Study
Comparison of S100β levels, and their correlation with hemodynamic indices in patients undergoing coronary artery bypass grafting with three different anesthetic techniques.
Cardiac surgery with aid of cardiopulmonary bypass (CPB) is associated with neurological dysfunction. The presence of cerebrospecific protein S100β in serum is an indicator of cerebral damage. This study was designed to evaluate the influence of three different anesthesia techniques, on S100β levels, in patients undergoing coronary artery bypass grafting on CPB. ⋯ It was concluded that maximum rise in S100β levels occurs immediately after CPB with a gradual decline in next 24 h. The rise in S100β levels is significantly less in patients administered sevoflurane in comparison to isoflurane or TIVA. Hemodynamic parameters had no influence on the S100β levels during the first 24 h after surgery.

Randomized Controlled Trial
Effect of prophylactic amiodarone in patients with rheumatic valve disease undergoing valve replacement surgery.
The study was carried out to evaluate the effect of prophylactic single-dose intravenous amiodarone in patients undergoing valve replacement surgery. Maintenance of sinus rhythm is better than maintenance of fixed ventricular rate in atrial fibrillation (AF) especially in the presence of irritable left or right atrium because of enlargement. Fifty-six patients with valvular heart disease with or without AF were randomly divided into two groups. ⋯ Defibrillation or cardio version was needed in 7.14% patients in group I and 28.57% patients in group II (P=0.078). A single prophylactic intraoperative dose of intravenous amiodarone decreased post bypass arrhythmia in this study in comparison to the control group. Single dose of intraoperative amiodarone may be used to decrease postoperative arrhythmia in open heart surgery.
