Randomized Controlled Trial Comparative Study
Systemic lidocaine decreases the Bispectral Index in the presence of midazolam, but not its absence.
To evaluate the effects of intravenous (IV) lidocaine on the Bispectral Index (BIS) in the presence or absence of midazolam. ⋯ IV lidocaine decreases BIS in the presence of midazolam, suggesting that the effect of lidocaine on BIS is not direct, but rather results from modulation by midazolam.

Randomized Controlled Trial
Does the covering of children during induction of anesthesia have an effect on body temperature at the end of surgery?
To determine whether the covering of healthy children during anesthetic induction reduces hypothermia at the end of minor surgeries. ⋯ Leaving healthy children uncovered during induction of general anesthesia does not have a clinically significant effect on core temperature at the end of induction or of surgery.

Comparative Study Controlled Clinical Trial
Shoulder and head elevation improves laryngoscopic view for tracheal intubation in nonobese as well as obese individuals.
To determine whether shoulder and head elevation, such that the patient's ear lies at or higher than the sternum ("ramp"), improves laryngoscopic grade in adult patients of various body mass index (BMI) values. ⋯ Shoulder and head elevation by any means that brings the patient's sternum onto the horizontal plane of the external auditory meatus maintains or improves laryngoscopic view significantly.

Acquired tracheoesophageal fistula (TEF) is a life-threatening disorder of the airway that requires early diagnosis and treatment. The case of an infant who had delayed development of a TEF following endoscopic removal of a disc battery lodged in the midesophagus is reported. A repeat bronchoscopy, performed for respiratory distress 4 days later, showed a large defect in the posterior wall of the distal trachea, including the carina. A Foley catheter was used for airway management in the repair of the acquired TEF.

To analyze whether patient characteristics, ambulatory facility type, anesthesia provider and technique, procedure type, and temporal factors impact the outcome of unexpected disposition after ambulatory knee and shoulder surgery. ⋯ The decreased risk for unexpected disposition associated with more recent data and with freestanding versus hospital-based facilities may represent improvements in efficiency, while the decreased odds for such disposition status associated with the use of other than general or regional anesthesia may be related to a lower invasiveness of cases. We found an increased risk of adverse disposition in cases where the anesthesia provider was a nonanesthesiology professional. No difference in this outcome was noted when an anesthesia care team provided care.
