Randomized Controlled Trial Comparative Study
Suction catheter guided insertion of the ProSeal laryngeal mask airway is superior to the digital technique.
We tested the hypothesis that digital insertion of the ProSeal laryngeal mask airway (ProSeal LMA) is more successful when using a suction catheter (SC) as a guide. ⋯ The SC-guided technique is more frequently successful than the digital technique and is associated with less mouth trauma during insertion of the ProSeal LMA. We suggest that the SC technique may be a useful alternative when the digital technique fails.

Randomized Controlled Trial Comparative Study
Bispectral index and regional cerebral oxygen saturation during propofol/N2O anesthesia.
A study was undertaken to compare the influence of midazolam, isoflurane, and aminophylline (which may antagonize anesthetic action) on bispectral index (BIS) and regional cerebral oxygen saturation (rSO(2)) during propofol/N(2)O anesthesia, and to test the hypothesis that the drug-induced changes in BIS values are accompanied by a change in rSO(2). ⋯ Midazolam or isoflurane-induced decreases in the BIS during propofol anesthesia were not accompanied by a decrease in rSO(2). Aminophylline significantly increased the BIS score during propofol anesthesia, suggesting that aminophylline can antagonize, at least in part, the sedative actions of propofol.

Historical Article
Training and development of anesthesia in Nepal - 1985 to 2005.
To describe the self-sustaining anesthesia training and development program in Nepal from 1985 through 2005, and the Canadian contributions. ⋯ The devotion of Nepalese anesthesiologists in teaching and training, strong guidance from Canadian medical faculties, and local government support have contributed to the successful development of Nepalese anesthesia training programs. Establishment of the training programs has assisted recruitment of trained anesthesiologists to different regional hospitals. Finally, the formation of a national society, with an organized annual symposium has improved professional self-esteem, and raised the profile of anesthesiology in Nepal.

Case Reports
Aortic dissection and hypothermic arrest in a Jehovah's Witness patient: a case for recombinant factor VIIa?
To present a case of survival of a cognitively intact Jehovah's Witness patient with an aortic dissection who underwent hypothermic arrest. Recombinant factor VIIa, but no blood products were administered. ⋯ Patients who conscientiously object to the transfusion of blood products may present a considerable anesthetic challenge, especially those at risk from coagulopathy associated with CPB and hypothermic circulatory arrest. Recombinant factor VIIa may play a role in hemostasis management of these individuals, however, well-designed randomized controlled trials need to be undertaken to establish the efficacy and risks related to this potential indication.
