Randomized Controlled Trial Comparative Study
Comparison of a single-use GlideScope Cobalt videolaryngoscope with a conventional GlideScope for orotracheal intubation.
This study was conceived to compare the single-use GlideScope Cobalt videolaryngoscope with the conventional GlideScope videolaryngoscope for orotracheal intubation, as judged by time to intubation (TTI) and ease of intubation. ⋯ The GlideScope Cobalt has similar performance characteristics compared with the conventional GlideScope videolaryngoscope when used for orotracheal intubation. The two devices can likely be used interchangeably. (ClinicalTrials.gov number, NCT00459797.).

Randomized Controlled Trial Comparative Study
Spinal mepivacaine with fentanyl for outpatient knee arthroscopy surgery: a randomized controlled trial.
The foremost limitation of local anesthetic solutions for spinal anesthesia in the outpatient setting is prolonged motor blockade and delayed ambulation. The purpose of this study was to determine if the addition of intrathecal fentanyl to low-dose spinal mepivacaine provides adequate anesthesia with shorter duration of functional motor blockade for ambulatory knee surgery compared with spinal mepivacaine alone. ⋯ When compared with 45 mg isobaric mepivacaine 1.5%, an intrathecal dose of 30 mg isobaric mepivacaine 1.5% plus 10 microg fentanyl produces reliable anesthesia, hastens block regression, shortens stay in Phase I recovery, and enables earlier ambulation for patients undergoing unilateral knee arthroscopy (Registration no. NCT00803725).

Randomized Controlled Trial Comparative Study
Intravenous dexmedetomidine, but not midazolam, prolongs bupivacaine spinal anesthesia.
Midazolam has only sedative properties. However, dexmedetomidine has both analgesic and sedative properties that may prolong the duration of sensory and motor block obtained with spinal anesthesia. This study was designed to compare intravenous dexmedetomidine with midazolam and placebo on spinal block duration, analgesia, and sedation in patients undergoing transurethral resection of the prostate. ⋯ Intravenous dexmedetomidine, but not midazolam, prolonged spinal bupivacaine sensory blockade. It also provided sedation and additional analgesia.
