Randomized Controlled Trial Comparative Study
Effects of preoperative oral beta blocker versus intraoperative nitroprusside or esmolol on quality of surgical field during tympanoplasty.
To determine whether orally administered atenolol provides an optimal surgical field in comparison to intravenous sodium nitroprusside or esmolol during tympanoplasty. ⋯ Although the three drugs are acceptable for obtaining an optimum surgical field, preoperative oral beta blocker appeared to be rapid in onset and was simpler to implement.

Randomized Controlled Trial
Rapid injection of propofol reduces vascular pain and facilitates Laryngeal Mask Airway insertion.
To compare the clinical efficacy of a rapid injection of propofol in regard to pain and ability to facilitate Laryngeal Mask Airway (LMA) insertion. ⋯ The rapid administration of propofol reduces pain and facilitates LMA insertion versus slow administration of propofol.

Randomized Controlled Trial
The effects of hormonal status on upper airway patency in normal female subjects during propofol anesthesia.
To determine the mechanical upper airway properties and compensatory neuromuscular responses to obstruction during propofol anesthesia in the follicular and luteal phases of the menstrual cycle. ⋯ Menstrual phase has an effect on anatomical alterations (mechanical properties) in the hypotonic upper airway during propofol anesthesia.
