BACKGROUND AND OBJECTIVES Electroconvulsive therapy (ECT) is commonly used for treatment of depression, mania and affective disorders. Anaesthetics for general anaesthesia during ECT should have rapid onset, rapid emerge, not interfere with seizure activity and not shorten seizure duration. The aim of this study is to compare effects of enflurane, a(More)
BACKGROUND Effective noninvasive mechanical ventilation (NIV) requires a patient to be comfortable and in synch with the ventilator, for which sedation is usually needed. Choice of the proper drug for sedation can lead to improved clinical outcomes. OBJECTIVE The aim of this study was to compare the effectiveness of dexmedetomidine and midazolam on(More)
BACKGROUND Pneumoperitoneum (P) created to facilitate laparoscopy (L) is associated with splanchnic hypoperfusion, ischemia/reperfusion (I/R) injury, and oxidative stress. AIM This study investigated the effects of pre- and post-laparoscopic conditioning, zinc, pentoxifylline (PTX), and N-acetylcysteine (NAC) on markers of I/R injury in an animal model.(More)
INTRODUCTION Invasive methods currently applied to the respiratory tract may result in impaired movement of the cricoarytenoid joint with hoarseness and immobility of the vocal ligament. Hoarseness after tracheal intubation is reported as a high incidence in patients who receive general anaesthesia. In most cases, the symptoms are temporary and improve(More)
UNLABELLED Ischemia/reperfusion (I/R) occurs in a number of pathological conditions, including myocardial infarction, stroke, aortic surgery, cardiopulmonary bypass surgery, organ transplantation, resuscitation, and critical care. Massive and abrupt release of oxygen-free radicals after reperfusion triggers oxidative damage. Before critical operations or(More)
BACKGROUND AND OBJECTIVE The pneumoperitoneum has been shown to decrease femoral blood flow, resulting in venous stasis. We analyzed the effects of the pneumoperitoneum and epidural analgesia on femoral vein diameter and the peak flow rate of femoral vein during laparoscopic cholecystectomy. PATIENTS AND METHODS Forty patients were randomly allocated to(More)
BACKGROUND Pneumoperitoneum induced to facilitate laparoscopy is associated with splanchnic hypoperfusion, ischemia/reperfusion (I/R) injury, and oxidative stress. AIM This study investigated the effects of pre- and postlaparoscopic conditioning, zinc, pentoxifylline, and N-acetylcysteine on markers of I/R injury of the small intestine in an animal model.(More)
The aim of this study was to describe whether or not spinal anaesthesia with bupivacaine versus levobupivacaine has any effects on the QTc interval during caesarean section. Sixty healthy pregnant women scheduled for elective caesarean section were randomized to spinal anaesthesia with either bupivacaine (the bupivacaine group) or levobupivacaine (the(More)
The aim of this study was to report a new cause of cataract, namely snake bite induced cataract in a dog. A 3-year-old male mongrel dog was referred to our clinic for the assessment of cataract in both eyes. The dog was bitten by a snake nearly 4 months ago. A 40 dioptre acrylic lens with 13 mm haptics was implanted into the lens capsule. In the left eye,(More)
UNLABELLED The aim of this study is to investigate effect of enflurane that is a pro-convulsive anesthetic agent and propofol on seizure durations and recovery times during electroconvulsive therapy. METHODS The subjects were divided into two groups according to the induction anesthetics. Anesthesia was induced with enflurane 5% in group E or propofol 1.2(More)
