Randomized Controlled Trial Comparative Study Clinical Trial
The gum elastic bougie eases tracheal intubation while applying cricoid pressure compared to a stylet.
To compare the ease of tracheal intubation facilitated by the gum elastic bougie or the malleable stylet while applying cricoid pressure. ⋯ Applying cricoid pressure worsened laryngeal view. The use of a gum elastic bougie was more effective than the use of a stylet to facilitate intubation.

Randomized Controlled Trial Clinical Trial
Nitrous oxide produces minimal hemodynamic changes in patients receiving a propofol-based anesthetic: an esophageal Doppler ultrasound study.
Nitrous oxide (N(2)O) is a frequently used adjunct to propofol anesthesia. Although N(2)O reduces the requirement of propofol for induction and maintenance, the effects of both drugs on overall hemodynamics remain controversial. We tested the hypothesis that the addition of N(2)O to therapeutic doses of propofol alters hemodynamics and Doppler-derived variables evaluated with the esophageal Doppler monitor in a randomized, double-blinded, placebo-controlled design. ⋯ Propofol causes dose-dependent decreases in ABF and MAP; however, 70% N(2)O produces minimal hemodynamic and Doppler-derived variable changes under target-controlled propofol infusion at therapeutic concentrations.
