Randomized Controlled Trial Comparative Study
The effects of propofol-midazolam-ketamine co-induction on hemodynamic changes and catecholamine response.
To compare the clinical efficacy of co-induction with propofol-midazolam-ketamine with etomidate as the sole induction agent. ⋯ The higher norepinephrine/epinephrine ratio noted in the single-drug group may be implicated in lower adrenal sympathetic activity. Propofol-midazolam-ketamine co-induction may be used instead of etomidate for anesthesia induction in patients with hemodynamic instability.

Randomized Controlled Trial
Prewarming of the i-gel facilitates successful insertion and ventilation efficacy with muscle relaxation: a randomized study.
To determine if prewarming of the i-gel (Intersurgical, Wokingham, United Kingdom) improves insertion and ventilation efficacy with muscle relaxation in patients undergoing elective surgery. ⋯ Prewarming the i-gel to 42°C demonstrated a higher successful ventilation initiation.
