Randomized Controlled Trial Clinical Trial
Effect of dexmedetomidine on the minimum alveolar concentration (MAC) of sevoflurane in adults age 55 to 70 years.
To determine the effect of two target dexmedetomidine infusions (0.3 ng/ml and 0.6 ng/ml) on the minimal alveolar concentration (MAC) of sevoflurane in adults age 55 to 70 years. ⋯ Dexmedetomidine 0.7 ng/ml decreased the MAC of sevoflurane by 17%, whereas there was no difference between the placebo and the dexmedetomidine 0.39 ng/ml group.

Case Reports
Use of laryngeal mask airway in a patient requiring continuous positive airway pressure: a case report.
The successful use of a laryngeal mask airway over a 48-hour period is reported in a patient with partial upper airway obstruction who required continuous positive airway pressure.

Randomized Controlled Trial Clinical Trial
Interaction modeling of propofol and sufentanil on loss of consciousness.
To examine the possible pharmacodynamic interaction of propofol and sufentanil with respect to the induction of loss of consciousness. ⋯ Our results give no evidence of additional hypnotic properties of sufentanil compared to the other fentanyl congeners, although logistic regression may be of limited value in modeling interaction of hypnotic-analgesic combinations.

Randomized Controlled Trial Clinical Trial
Remifentanil as an adjuvant during desflurane anesthesia facilitates early recovery after ambulatory surgery.
To investigate the effect of using a remifentanil infusion during desflurane anesthesia on the early recovery profile and side effects. ⋯ The adjunctive use of a remifentanil infusion (0.07 +/- 0.03 microgram.kg-1.min-1) during desflurane-N2O anesthesia facilitated early recovery without increasing PONV, pain, or the need for rescue medication after laparoscopic surgery.

Randomized Controlled Trial Clinical Trial
Effects of sympathetic blockade on the efficiency of forced-air warming during combined spinal-epidural anesthesia for total hip arthroplasty.
To evaluate if active cutaneous warming of the two upper limbs with reflex vasoconstriction is less effective in maintaining intraoperative normothermia than warming the vasodilated unoperated lower limb during combined spinal-epidural anesthesia (CSE). ⋯ Forced-air cutaneous warming allows the anesthesiologist to maintain normothermia during CSE for total hip replacement even if the convective blanket is placed on a relatively small skin surface with reflex vasoconstriction. Placing the forced-air warming system on the vasodilated unoperated lower limb may be troublesome to the surgeons and does not offer clinically relevant advantages in warming efficiency.
