BIS, MLAEPs, haemodynamic parameters and propofol plasma concentration were determined at various stages before, during and

after anaesthesia. During anaesthesia, BIS values were always maintained between 40 and 60.\n\nResults Anaesthesia significantly increased latency of Pa and Nb compared with when patients were awake (P<0.01). After extubation, the latency of Pa and Nb significantly decreased and basically returned to baseline level. BIS and latency of both Pa and Nb did not differ between groups. Also, the propofol induction dose (mean +/- SD: TCI, Selleck FK228 2.09 +/- 0.36 mg kg(-1); MCI, 2.06 +/- 0.16 mg kg(-1)) and total dose (TCI, 5.57 +/- 0.96 mg kg(-1) h(-1); MC, 5.79 +/- 0.87 mg kg(-1) h(-1)) and measured plasma propofol concentration during anaesthesia did not differ between groups. At 15 min after intubation, the mean predicted plasma concentration (2.2 +/- 0.2 mu g ml(-1)) differed significantly from the measured plasma concentration (2.8 +/- 1.2 mu g ml(-1)). No correlation was observed between predicted and measured

propofol plasma concentrations.\n\nConclusion Titration of propofol to achieve a comparable depth of anaesthesia results in comparable propofol consumption and recovery variables regardless of the type of propofol administration. Propofol GSK3326595 plasma concentration showed large interindividual variability. Eur J Anaesthesiol 26:928-935 (C) 2009 European Society of Anaesthesiology.”
“In tetrapods, the ability to ingest food on land is based on certain morphological features of the oropharynx in general and the feeding apparatus in particular. Recent paleoecological studies imply that terrestrial feeding has evolved secondarily in turtles, so they had to meet the morphological oropharyngeal requirements independently to other amniotes. This study is designed to improve our limited knowledge about the oropharyngeal morphology of tortoises by analyzing in detail the oropharynx in Manouria emys emys. Special emphasis is placed on the form and function of the tongue. Even if Manouria is considered a basal member of the only terrestrial turtle clade

and was hypothesized to have retained some features reflecting an aquatic ancestry, Manouria shows oropharyngeal characteristics found in more derived testudinids. Accordingly, the www.selleckchem.com/products/ly3039478.html oropharyngeal cavity in Manouria is richly structured and the glands are large and complexly organized. The tongue is large and fleshy and bears numerous slender papillae lacking lingual muscles. The hyolingual skeleton is mainly cartilaginous, and the enlarged anterior elements support the tongue and provide insertion sides for the well-developed lingual muscles, which show striking differences to other reptiles. We conclude that the oropharyngeal design in Manouria differs clearly from semiaquatic and aquatic turtles, as well as from other reptilian sauropsids. J. Morphol.
