[A prospective, randomized, double-blinded control study on comparison of tramadol, clonidine and dexmedetomidine for post spinal anesthesia shivering].

Introduction: Shivering, a common intraoperative problem under spinal anesthesia increases the oxygen consumption considerably and is uncomfortable and distressing to the patient, anesthesiologist as well as surgeon. The present study was designed to explore the effectiveness of tramadol, clonidine and dexmedetomidine in the treatment of post spinal anesthesia shivering and to look for their adverse effects.

Methods: This prospective, randomized, double blinded control study was done on 90 patients who developed shivering under spinal anesthesia.

Comparison of Levosimendan versus Dobutamine in Patients with Moderate to Severe Left Ventricular Dysfunction Undergoing Off-pump Coronary Artery Bypass Grafting: A Randomized Prospective Study.

Context: Recent upsurge in referral of patients with compromised left ventricular (LV) function for cardiac surgery has led to an increasing use inotropes to achieve improvement of tissue perfusion in the perioperative period.

Aims And Objectives: To compare the hemodynamic effects and immediate postoperative outcomes with levosimendan and dobutamine in patients with moderate to severe LV dysfunction undergoing off-pump coronary artery bypass grafting (OPCAB).

Settings And Design: University teaching hospital, randomized control study.
