Hepatic encephalopathy (HE) is one of the major complications of cirrhosis. Experimental and clinical findings observed in liver, muscle and brain have provided new insights into the ammonia mechanism of action. L-Carnitine (LC), inducing ureagenesis, may decrease blood and brain ammonia levels. 120 patients meeting inclusion criteria were randomized either(More)
Multiple therapeutic modalities have been used to treat hepatic encephalopathy. l-Acetylcarnitine (LAC) is a physiologically active substance that improves both the energetic and the neurotransmission profiles. LAC is able to cross the hematoencephalic barrier and reach the cerebral regions, where the acetylic group may be utilized. The aim of this work was(More)
We investigated whether intervention with antioxidant vitamins C and E in enteral feeding influenced oxidative stress and clinical outcome in critically ill patients. Two-hundred-sixteen patients expected to require at least 10 days of enteral feeding completed the study. One-hundred-five patients received enteral feeding supplemented with antioxidants, and(More)
BACKGROUND AND OBJECTIVE Levobupivacaine is the most recently introduced local anaesthetic into clinical practice. In a randomized double-blinded study, the onset, intraoperative tolerance, postoperative analgesic effect, motor blockade and any adverse reactions produced by levobupivacaine were compared with ropivacaine. METHODS Sixty children, ASA I-II,(More)
BACKGROUND Infants are noted to frequently sleep during spinal anesthesia, with a concomitant fall in Bispectral Index. However, there are suggestions that EEG derived anesthesia depth monitors have inferior performance in infants. The aim of this study was to quantify the degree of sedation during spinal anesthesia in infants using another EEG derived(More)
BACKGROUND AND OBJECTIVE Sedation is commonly used to facilitate diagnostic procedures in children. The aim of our study was to investigate sedation in children using propofol alone or combined with fentanyl or midazolam with regard to efficacy, adverse reactions or side-effects related to the drugs, ease of operation for the endoscopist, and time to(More)
STUDY OBJECTIVE To compare the postoperative analgesia of three different concentrations of levobupivacaine for ilioinguinal/iliohypogastric (II/IH) block in children undergoing inguinal hernia repair. DESIGN Double-blind, prospective, randomized, controlled trial. SETTING Operating room and postoperative recovery area of a university hospital. (More)
BACKGROUND Comparing relative potency of new local anesthetics, such as levobupivacaine and ropivacaine, by the minimum local analgesic concentration model has not been described for caudal anesthesia. Therefore, we performed a prospective, randomized, double-blind study to determine the minimum local analgesic concentrations of a caudal single shot of(More)
