Cricoid pressure: are two hands better than one?
One hundred and twenty patients were studied to compare the view of the larynx at laryngoscopy with one- or two-handed cricoid pressure applied. A blinded crossover technique was employed. When the grade of laryngeal view achieved with either type of cricoid pressure was compared using a 4-point scale there was no significant difference. ⋯ A two-handed technique has been advocated to improve intubation conditions when cricoid pressure is required. It has several disadvantages, its efficacy has not been proven and this study suggests it does not improve the view at laryngoscopy. Two-handed cricoid pressure should no longer be advocated unless an advantage over one-handed cricoid pressure can be shown.

[Attempt at a definition of the individual anesthesia level by repetitive pain stimulation: correlation with EEG findings].
Previous studies using EEG for assessment of depth of anaesthesia correlate anaesthetic concentration with the anaesthetic stage. This procedure neglects the well known effect of individual different susceptibility to anaesthetics. Thus, patients receiving similar concentrations of anaesthetics may not necessarily be at the same level of "anaesthetic depth". The aim of this study was to define an interindividual comparable level of anaesthesia by recording the autonomic cardiovascular reaction to a standardised painful stimulus (tetanic stimulus, 80 mA, 100 Hz). ⋯ This method to define individual depth of anaesthesia as described, results in more consistent EEG patterns and may be useful in relating EEG to depth of anaesthesia.

Surgery and the tiny baby: sensorineural outcome at 5 years of age. The Victorian Infant Collaborative Study Group.
To determine whether an association exists between long-term sensorineural outcome and the need for surgery requiring general anaesthesia during the primary hospitalization in extremely preterm (<27 weeks of gestational age) or extremely low birthweight (ELBW birthweight <100Og) infants. ⋯ There is an adverse association between the need for surgery requiring general anaesthesia during the primary hospitalization and sensorineural outcome in extremely preterm or ELBW infants.

Comparative Study
Anesthesia induced in pigs by use of a combination of medetomidine, butorphanol, and ketamine and its reversal by administration of atipamezole.
To develop an IM administrable anesthetic combination for pigs. ⋯ Medetomidine, butorphanol, and ketamine-induced anesthesia is available for short-term major surgery in pigs.

To evaluate selected hemodynamic, respiratory, and behavioral responses to propofol in horses premedicated with xylazine or detomidine. ⋯ Xylazine or detomidine-propofol combinations likely will not replace common anesthetic induction techniques for horses. However, recovery characteristics associated with propofol encourage further study in horses.
