During induction of general anesthesia hypertension and tachycardia caused by tracheal intubation may lead to cardiac ischemia and arrhythmias. In this prospective, randomized study, dexmedetomidine has been used to attenuate the hemodynamic response to endotracheal intubation with low dose fentanyl and etomidate in patients undergoing myocardial(More)
OBJECTIVE Postoperative respiratory functions, arterial blood gases, blood loss and clinical outcome following coronary artery bypass surgery (CABG) were assessed in a prospective randomized single-blind (patient- blind) clinical study comparing two different techniques of internal thoracic artery (ITA) harvesting. METHODS Fifty-four patients admitted for(More)
BACKGROUND The aim of our study was to evaluate the pulmonary and hemodynamic effects of two different recruitment maneuvers after open heart surgery. METHODS Sixty patients undergoing coronary artery bypass surgery were randomized into three groups after operation: recruitment maneuver with continuous positive airway pressure (CPAP) (CPAP-40 group, n =(More)
A 33-year-old woman who had undergone a Cabrol-type aortic root replacement for acute aortic dissection during labor 27 months ago was admitted with chest pain. Electron-beam tomography and coronary angiography showed stenosis at the level of the anastomosis. Urgent coronary revascularization was performed using bilateral internal mammary artery grafts.(More)
OBJECTIVE To evaluate whether the deleterious effects of cardiopulmonary bypass (CPB) can be overcome by phentolamine-induced pharmacologic vasodilation in pediatric patients with congenital heart disease. DESIGN Prospective, randomized, clinical study. SETTING Single university hospital. PARTICIPANTS Forty-three pediatric patients undergoing open(More)
BACKGROUND Ketamine is an analgesic suitable for the induction of anesthesia during Caesarean delivery. This double blind, randomized trial examined the effect of intravenous ketamine used before the induction of general anesthesia on morphine consumption, immediate and long term postoperative pain after Cesarean delivery. METHODS One hundred and forty(More)
OBJECTIVE The purpose of this study was to evaluate the analgesic effect of single-dose preoperative gabapentin on postoperative pain and morphine consumption after cardiac surgery. DESIGN A randomized, double-blind, placebo-controlled, clinical study. SETTING A single university hospital. PARTICIPANTS Sixty patients undergoing coronary artery bypass(More)
BACKGROUND The aim of our study was to evaluate the pulmonary effects of noninvasive ventilation (NIV) with or without recruitment maneuver (RM) after open heart surgery. METHODS One-hundred patients undergoing coronary artery bypass surgery were randomized into four groups after the operation: 1) RM with sustained inflation during mechanical ventilation(More)
