Randomized Controlled TrialForces applied to the maxillary incisors by video laryngoscopes and the Macintosh laryngoscope.
Modern video laryngoscopes (VLSs) provide a superior view of the glottis, facilitating easier intubations. This study evaluates the forces applied to the maxillary incisors when using various VLSs and a Macintosh blade. ⋯ All VLSs considered were safer for the patient than was the Macintosh blade in terms of the forces applied to the maxillary teeth, time, number of insertion attempts, and view achieved of the glottic arch. There is a small, but significant, difference in the time and number of insertion attempts required during laryngoscopy with the different VLSs. There was no difference in the forces applied. The geometry of the respective blades may be an important component in the ease of laryngoscopy.

Randomized Controlled Trial Comparative StudySelective spinal anesthesia for outpatient transurethral prostatectomy (TURP): randomized controlled comparison of chloroprocaine with lidocaine.
This is a study comparing two short-acting local anesthetics lidocaine and 2-chloroprocaine in combination with fentanyl, to provide selective spinal anesthesia for outpatient transurethral resection of the prostate (TURP). ⋯ Selective spinal anesthesia with chloroprocaine and lidocaine for TURP yielded comparable results for clinical characteristics. Further research on transient neurological symptom and cauda equina risk with chloroprocaine is warranted.

Randomized Controlled TrialThe analgesic effect of continuous subacromial bupivacaine infusion after arthroscopic shoulder surgery: a randomized controlled trial.
The benefits of subacromial local anesthetic infusion are controversial. The aim of this study was to evaluate the efficacy of subacromial bupivacaine infusion after arthroscopic acromionplasty and rotator cuff procedures. ⋯ Considering the low need of opioids, expenses and technical problems in these patients, subacromial 5.0 mg/ml bupivacaine infusion 2 ml/h confers only moderate and probably clinically insignificant efficacy compared with placebo. This efficacy might be overweighed by the disadvantages.
