Effects of reduction of carrier gas flow rate on sevoflurane and isoflurane consumption and costs.
To evaluate whether sevoflurane and isoflurane consumption would be actually halved by halving the carrier gas flow rate, as predicted by a theoretical model, we measured the consumed volume of liquid sevoflurane and isoflurane and total costs of anesthetic gas at carrier gas flow rates of 3 and 61·min-1. ⋯ Halving the carrier gas flow rates halved the consumption of isoflurane but not of sevoflurane, indicating that factors other than carrier gas flow rates are involved in determining consumption in the clinical setting.

The purpose of this study was to confirm the changes in extra-aand intravascular fluid distribution during an i.v. influsion of hyperoncotic Dextran solution. ⋯ One-fourth to one-third of the plasma expanding effect of 6% Dextran 70 solution was ascribed to direct fluid drawing from the extravascular space, and the rest was due to both the decrease in plasma filtration into extravascular space and the increase in lymphatic restoration of EVW.
