Randomized Controlled Trial Clinical Trial
Sevoflurane-N2O versus propofol/isoflurane-N2O during elective surgery using the laryngeal mask airway in adults.
To compare a sevoflurane-nitrous oxide (N2O) general anesthetic technique with a standard technique of propofol for induction, and isoflurane-N2O for maintenance. ⋯ Sevoflurane-N2O and propofol provided comparable conditions for LMA insertion. Sevoflurane-N2O was not associated with a faster return of consciousness or faster time to exit the OR compared with isoflurane-N2O.

Randomized Controlled Trial Comparative Study Clinical Trial
The influence of preemptive spinal anesthesia on postoperative pain.
To examine the influence of spinal anesthesia on postoperative pain and postoperative opioid requirements. ⋯ Preoperative neural blockade may reduce postoperative analgesic requirements.

Randomized Controlled Trial Clinical Trial
Low-dose intrathecal clonidine combined with sufentanil as analgesic drugs in abdominal gynecological surgery.
To determine whether a low dose of spinal clonidine either alone or combined with sufentanil would provide effective analgesia following abdominal surgery, as a supplement to bupivacaine spinal anesthesia. ⋯ Intrathecal 15- and 30-microg clonidine doses expanded the anesthesia sensory block and duration of motor block, and provided analgesia.

Randomized Controlled Trial Clinical Trial
Hemodynamic effects of simultaneous administration of intravenous ephedrine and spinal anesthesia for cesarean delivery.
To evaluate the hemodynamic effects of an intravenous (IV) ephedrine bolus given simultaneously with spinal anesthesia for cesarean delivery. ⋯ 10 mg of IV ephedrine given at the time of spinal anesthesia, and after a 10 mL/kg lactated Ringers fluid bolus, does not diminish the incidence or severity of hypotension in parturients undergoing cesarean delivery.

Randomized Controlled Trial Clinical Trial
Preoperative clonidine attenuates stress response during emergence from anesthesia.
To investigate whether a single preoperative IV dose of clonidine blunts the hemodynamic and hyperadrenergic responses not only to intubation, but also to extubation. ⋯ A single preoperative IV dose of clonidine (3 microg/kg) blunts the hemodynamic responses due to extubation in noncardiac surgery of intermediate duration.
