Comparison of Ropivacaine and Levobupivacaine in Supraclavicular Brachial Plexus Blocks-A Double Blinded Randomized Control Study.

Background: Brachial plexus anaesthesia has been an indispensable tool in the anaesthesiologist's armamentarium. Clinical studies have shown that levobupivacaine and ropivacaine have fewer adverse effects on the cardiovascular and central nervous system making them more advantageous in regional anaesthesia techniques. Less information is available regarding their comparable clinical data.

Association between frailty, cerebral oxygenation and adverse post-operative outcomes in elderly patients undergoing non-cardiac surgery: An observational pilot study.

Background And Aims: Although both frailty and low cerebral oxygen saturation increase the risk of post-operative complications, their relationship is yet to be investigated. The purpose of this observational study was to investigate the association between frailty, intraoperative cerebral oxygen saturation and post-operative complications in elderly patients undergoing non-cardiac surgery.

Methods: After approval from the Institutional Review Board, 25 elderly patients (>65 years) undergoing non-cardiac major surgery were included in this study.

Anesthetic considerations for endovascular abdominal aortic aneurysm repair.

Aneurysm is defined as a localized and permanent dilatation with an increase in normal diameter by more than 50%. It is more common in males and can affect up to 8% of elderly men. Smoking is the greatest risk factor for abdominal aortic aneurysm (AAA) and other risk factors include hypertension, hyperlipidemia, family history of aneurysms, inflammatory vasculitis, and trauma.

Effect of levosimendan on hemodynamic changes in patients undergoing off-pump coronary artery bypass grafting: a randomized controlled study.

Aims And Objective: We tested the hypothesis that use of levosimendan would be associated with better perioperative hemodynamics and cardiac function during off-pump coronary artery bypass grafting (OPCAB) in patients with good left ventricular function.

Materials And Methods: Thirty patients scheduled for OPCAB were randomized in a double-blind manner to receive either levosimendan 0.1 μg/kg/min or placebo after induction of general anesthesia.

The effects of dexmedetomidine on attenuation of stress response to endotracheal intubation in patients undergoing elective off-pump coronary artery bypass grafting.

This study was designed to study the efficacy of intravenous dexmedetomidine for attenuation of cardiovascular responses to laryngoscopy and endotracheal intubation in patients with coronary artery disease. Sixty adult patients scheduled for elective off-pump coronary artery bypass surgery were randomly allocated to receive dexmedetomidine (0.5 mcg/kg) or normal saline 15 min before intubation.

Early extubation in tetralogy of Fallot patients after complete repair.

Aim: To document the feasibility of early extubation and to know the effect of age, weight, and post-operative right ventricle/left ventricle ratio in early extubation in intracardiac repair for tetralogy of Fallot.

Materials And Methods: This is a prospective study of 76 consecutive patients undergoing intracardiac repair between January, 2010 and April, 2010. The patients were compared between duration of ventilation with age, weight, and post-operative left ventricle/right ventricle ratio.

Scimitar syndrome: experience with 6 patients.

Scimitar syndrome is a rare congenital anomaly characterized by anomalous pulmonary venous drainage to the inferior vena cava, causing a left-to-right shunt. Six patients with scimitar syndrome were diagnosed in our hospital between 2002 and 2008. There were 4 girls and 2 boys; 4 < 5 kg in weight, 2 < 8 kg in weight.
