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.

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.

The aim of this study was to assess whether passive smoking affected the frequency of airway complications in children undergoing general anaesthesia. One hundred and twenty-five children undergoing general anaesthesia for elective daycase surgery were monitored for adverse respiratory events and desaturation during induction, intra-operatively and in the recovery room. Oxygen saturation was monitored throughout and a venous sample was taken for estimation of carboxyhaemoglobin levels. ⋯ This was related to the cumulative number of cigarettes smoked by individuals to whom the child was exposed (p < 0.05). Neither carboxyhaemoglobin levels nor domiciliary address were predictive of desaturation. This study suggests that passive smoking contributes to postoperative arterial oxygen desaturation following general anaesthesia in children.

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.
