Randomized Controlled Trial Comparative Study
Comparison of propofol-dexmedetomidine, tiopental-dexmedetomidine and etomidate-dexmedetomidine combinations' effects on the tracheal intubation conditions without using muscle relaxants.
In our study, we aimed to compare the endotracheal intubation conditions without muscle relaxants during induction with the combinations of dexmedotimidine-propofol, dexmedotimidine-thiopenthal and dexmedetomidine-etomidate. ⋯ In conclusion, we determined that best intubation conditions without muscle relaxants were achieved with propofol-dexmedetomidine combination. None of the patients receiving etomidate -dexmedetomidine combination could be intubated without muscle relaxants (Tab. 6, Ref. 29).

Randomized Controlled Trial
The effects of nitrous oxide on vitamin B12 and homocysteine levels in methyltetrahydrofolate reductase gene mutation.
We aimed to investigate the effects of nitrous oxide on plasma total homocysteine and vitamin B12 levels in patients with or without methyltetrahydrofolate reductase (MTHRF) gene mutation. ⋯ We conclude that MTHRF gene polymorphism had no significant effects on postoperative plasma total homocysteine levels. However, we found that homocysteine levels might rise in patients who received general anesthesia with nitrous oxide for longer than 3 hours (Tab. 7, Ref. 26).
