Randomized Controlled Trial
The effects of preoperative, video-assisted anesthesia education in Spanish on Spanish-speaking patients' anxiety, knowledge, and satisfaction: a pilot study.
We studied the effect of an instructional video in Spanish on self-reported anxiety, knowledge about general anesthesia procedures, and satisfaction with the preoperative anesthesia process in patients requiring a Spanish interpreter. This prospective, randomized, nonblinded pilot study took place at Massachusetts General Hospital (MGH), a university-affiliated tertiary-care hospital. Twenty adult, ASA physical status 1, 2, and 3 patients, scheduled for elective surgery (gynecological, orthopedic, and intrabdominal surgery) during general anesthesia were studied. ⋯ There was an increase in satisfaction score in the video group (median increase 2 vs 0; P = 0.046). There was no difference in reported knowledge-improvement scores between the two groups (3.5 vs 4; P = 0.908). In Spanish-speaking patients, the addition of an instructional video in Spanish to a preanesthesia interview decreased anxiety and increased patient satisfaction.

Randomized Controlled Trial
Effects of dexmedetomidine on the ratio of T Helper 1 to T Helper 2 cytokines in patients undergoing laparoscopic cholecystectomy.
To investigate the effect of dexmedetomidine on T helper 1 (Th1) and T helper 2 (Th2) cytokines and their ratio during and after surgery. ⋯ Dexmedetomidine plays an immunomodulatory role, shifting the Th1/Th2 cytokine balance toward Th1 in patients with surgical and anesthetic stress.

A case of a preoperative airway examination performed using telemedicine is presented. The use of this technology has the ability to provide crucial information regarding the feasibility of office-based anesthesia in advance and limit schedule interruptions on the day of surgery.

Randomized Controlled Trial Comparative Study
Intranasal dexmedetomidine premedication reduces the minimum alveolar concentration of sevoflurane for tracheal intubation in children: a randomized trial.
To determine the effects of dexmedetomidine premedication on the minimum alveolar concentration of sevoflurane for tracheal intubation (MACTI) in children. ⋯ Intranasal dexmedetomidine premedication produces a dose-dependent decrease in the concentration of sevoflurane needed for tracheal intubation in children.
