Randomized Controlled Trial
The frequency of fentanyl-induced cough in children and its effects on tracheal intubation.
To determine if fentanyl-induced cough was dose-dependent in children and whether it could affect tracheal intubation. ⋯ Fentanyl at doses of one and two microg/kg may induce coughing in pediatric patients.

To evaluate the incidence of perioperative minor adverse events and to analyze patient satisfaction based on potential explanatory variables. ⋯ Minor events occur with a surprisingly high incidence and are significantly associated with patient dissatisfaction. Regional anesthesia is associated with fewer patient complaints and significantly higher postoperative patient satisfaction.

Case Reports
Clinical course of pain in a patient with neuropathic pain induced by ligation of an intercostal nerve.
A patient with severe right chest pain and mechanical allodynia induced by an intercostal drainage tube to his chest is presented. It was not relieved by treatment with diclofenac sodium and was worsened by movement and touch to the right chest wall. Mechanical allodynia was also present. The patient's wrenching pain disappeared immediately after stitch removal, but the dull pain and mechanical allodynia persisted, gradually decreasing to zero in 7 days.

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.
