Case Reports
Unusual presentation of perioperative ischemic optic neuropathy following major spine surgery.
Perioperative visual loss following spinal surgery has become of increasing concern among anesthesiologists, surgeons, and patients alike. Perioperative ischemic optic neuropathy often occurs in patients greater than 50 years of age, in association with a number of presumed risk factors, including diabetes, hypertension, small cup-to-disc ratio, preoperative anemia, intraoperative hypotension, prolonged operative time in the prone position, and significant blood loss during surgery. The visual loss is notably devastating, and generally leads to permanent disability. A 44-year-old man whose central visual acuity was completely preserved is presented.

Early misconceptions about nitrous oxide, an "invigorating" asphyxiant.
Well into the twentieth century, nitrous oxide was often suspected to support life in the manner of oxygen. Authorities contributing to that life-threatening misimpression include Humphry Davy, Gardner Q. ⋯ Crile. Concomitantly, deprivation of oxygen was long touted as a requisite for nitrous oxide anesthesia.

Randomized Controlled Trial Comparative Study
A comparative study of dexmedetomidine with midazolam and midazolam alone for sedation during elective awake fiberoptic intubation.
To evaluate the efficacy of dexmedetomidine with midazolam (DEX-MDZ) versus midazolam only (MDZ) for sedation during awake fiberoptic intubation (AFOI). ⋯ Dexmedetomidine in combination with low doses of midazolam is more effective than midazolam alone for sedation in AFOI.

Comfort and satisfaction during axillary brachial plexus block in trauma patients: comparison of techniques.
To investigate the comfort and satisfaction of patients with trauma of the upper limb during two different techniques of axillary brachial plexus block, electrical nerve stimulation and fascial pop. ⋯ In trauma patients, the fascial pop technique is effective, reduces sedation during axillary brachial plexus block, and has a higher patient acceptance rate than the electrical nerve stimulation technique.
