Randomized Controlled Trial Comparative Study
Effect of preoperative oral erythromycin, erythromycin-ranitidine, and ranitidine-metoclopramide on gastric fluid pH and volume.
To determine whether combining erythromycin with ranitidine is more efficacious than erythromycin or established ranitidine-metoclopramide combination in reducing the volume and acidity of gastric aspirate. ⋯ Erythromycin and ranitidine combination is more efficacious than erythromycin alone in reducing the acidity and volume of gastric fluid. No difference was found between erythromycin-ranitidine and ranitidine-metoclopramide combination.

We investigate an incident in which a carbon dioxide absorber caused difficulty with ventilation. The problem as it developed throughout the anesthetic, and clues that led to the determination that the carbon dioxide canister was the problem, is discussed.

Lipmann and Anfinsen: Nobel biochemists of Beecher's anesthesia laboratory.
Henry K. Beecher performed blood pH and gas analysis on patients in the 1940s, though the biochemical technology was not widely available until the 1950s. Two of Beecher's biochemist coworkers, Fritz Lipmann and Christian B. Anfinsen, went on to earn Nobel Prizes.

Randomized Controlled Trial Comparative Study
Epidural analgesia after scoliosis surgery: electrophysiologic and clinical assessment of the effects of bupivacaine 0.125% plus morphine versus ropivacaine 0.2% plus morphine.
To study the electrophysiologic and clinical effects of epidural morphine combined with either bupivacaine 0.125% or ropivacaine 0.2%. ⋯ After epidural administration during the study conditions, bupivacaine 0.125% and ropivacaine 0.2% combined with morphine allow for neurologic examination.

Randomized Controlled Trial
Blocking noise but not music lowers bispectral index scores during sedation in noisy operating rooms.
To determine whether playing music or blocking noise can reduce bispectral index (BIS) values during propofol sedation. ⋯ Blocking noise is more effective than playing music in reducing BIS scores during propofol sedation in a noisy environment.
