Randomized Controlled Trial Comparative Study
Remifentanil for the insertion and removal of long-term central venous access during monitored anesthesia care.
To determine the analgesic efficacy of three different rates of remifentanil infusion in patients undergoing insertion or removal of long-term central venous access devices during monitored anesthesia care and local anesthetic field infiltration. ⋯ For the insertion or removal of long-term central venous access devices, all three remifentanil infusion rates proved to be equally analgesic-efficient. However, the excessive sedation and tendency to respiratory and cardiovascular events associated with the highest remifentanil infusion rate renders such a rate less desirable for this purpose.

Randomized Controlled Trial Comparative Study
Pain on injection of propofol: a comparison of methylene blue and lidocaine.
To investigate whether methylene blue, given before injection of propofol, was effective in reducing the frequency and severity of pain associated with propofol injection. ⋯ Intravenous pretreatment with methylene blue appears to be effective in reducing the pain during propofol injection.

Randomized Controlled Trial Comparative Study
Addition of epinephrine to epidural bupivacaine infusions following initiation of labor analgesia with epidural fentanyl.
To evaluate the analgesic effects of the addition of epinephrine to a bupivacaine epidural infusion in early labor after a fentanyl bolus, following a lidocaine-epinephrine test dose. ⋯ The administration of 0.625 mg/mL bupivacaine with epinephrine 5 μg/mL at 10 mL/hr, compared with plain 0.625 mg/mL bupivacaine at 10 mL/hr, provided a longer time to re-dose, decreased pain scores at two time intervals, and had no significant difference in duration of labor or side effects.

Randomized Controlled Trial
Intravenous landiolol, a novel β(1)-adrenergic blocker, reduces the minimum alveolar concentration of sevoflurane in women.
To investigate the effect of intravenous (IV) landiolol, a novel β(1)-adrenergic blocker, on the minimum alveolar concentration (MAC) of sevoflurane in adult women. ⋯ IV landiolol reduces the MAC of sevoflurane in women by approximately 20%.

Randomized Controlled Trial Comparative Study
Indirect versus direct laryngoscopy for routine nasotracheal intubation.
To compare the effectiveness of the indirect laryngoscopes, Airtraq (A) and GlideScope (G), with the Macintosh (M) laryngoscope in routine nasotracheal intubation. ⋯ The Airtraq and GlideScope facilitated nasotracheal intubation more so than the Macintosh laryngoscope in adults with apparently normal airways.
