Randomized Controlled Trial Clinical Trial
Small doses of remifentanil or sufentanil for blunting cardiovascular changes induced by tracheal intubation: a double-blind comparison.
To compare the effects on cardiovascular changes induced by tracheal intubation when small doses of either remifentanil or sufentanil are used in the presence of midazolam. ⋯ In healthy normotensive patients without cardiovascular disease the use of a relatively small dose of either remifentanil or sufentanil after standard midazolam premedication results in a similar and clinically acceptable effectiveness in blunting the cardiovascular changes induced by tracheal intubation.

Randomized Controlled Trial Clinical Trial
Intravenous ketamine attenuates arterial pressure changes during the induction of anaesthesia with propofol.
To investigate whether the administration of ketamine before induction with propofol produces a smaller decrease in arterial pressure. ⋯ Administration of ketamine before induction with propofol preserved haemodynamic stability compared with induction with propofol alone.
