This duration may appear to be short. The BLUE protocol was performed by experienced operators it is true, but this was done with the aim of not interfering with the management that was underway. Doctors integrating the BLUE protocol in patient management are free to take more time. Several points explain our data, however. Since 1992, we have labeled our whole-body approach “fast-echo” because...

BACKGROUND Microsomal stearoyl-CoA desaturase1 (SCD1) is the rate limiting enzyme involved in the biosynthesis of monounsaturated fatty acids (MUFAs); palmitoleic (16:1) and oleic (18:1) acid from their respective substrates palmitic (16:0) and stearic (18:0) acids. The ratio of 18:1 to 18:0 has been implicated in the regulation membrane fluidity and function. SCD1 is abundantly expressed in ob...

Moderate to severe arterial oxygen desaturation (SaO2 75-88%) occurred in three of four patients who were given sedation during regional conduction block without the administration of oxygen. No desaturation occurred in six patients given oxygen 2 litre min-1 via a nasal catheter during similar procedures. It is concluded that patients undergoing regional conduction block with concurrent sedati...

We have studied response times of 30 anaesthetists to a standardized episode of arterial oxygen desaturation in a simulated patient, randomized to the use of either a fixed or variable pitch pulse oximeter. We wished to determine if a variable auditory signal was important in detecting adverse events. A variable pitch pulse signal had a shorter time to recognition of desaturation (P < 0.0001), ...
