Carbon monoxide (CO) is a colorless, odorless, nonirritating, toxic gas produced by the incomplete oxidation of hydrocarbons. Common sources of CO include motor vehicles, house fires, furnaces/heaters, and wood-burning stoves. ⋯ In the present study, we discuss compartment syndrome caused by CO poisoning in a 15-year-old boy. To our knowledge, this is the first CO poisoning case causing compartment syndrome.

Case Reports
Successful treatment of thyroid crisis accompanied by hypoglycemia, lactic acidosis, and multiple organ failure.
We describe a case of thyroid crisis with hypoglycemia, lactic acidosis, multiple organ failure, and disseminated intravascular coagulation--rare but severe complications of thyroid crisis. The patient was a 59-year-old Chinese woman who presented with evidence of heart failure and atrial fibrillation. Analysis of a blood sample yielded astonishing results: her blood glucose was 1.7 mmol/L, and lactate greater than 15 mmol/L with the arterial pH as 6.94. ⋯ Prompt treatments such as mechanical ventilation, plasma exchange, and continuous venovenous hemofiltration were preformed, along with antithyroid medication. The patient finally survived after 3 weeks of intensive care. We herein discuss the possible mechanisms of these metabolic disorders in thyroid crisis and possible therapeutic measures that could be used to reduce mortality.

We hypothesized that the oro-pharyngolaryngeal axes, occipito-atlanto-axial extension (OAA) angle and intubation distance would be influenced by the height of headrests. ⋯ We conclude that compared with no or 12-cm headrest, 6-cm headrest could facilitate more alignment of these axes, increase the OAA angle, and enlarge the intubation distance.

The aim of this study was to examine the effects of controlled hemorrhage and shock on oxygenation and ventilation using needle cricothyroidotomy and jet ventilation in an animal model. ⋯ Hemorrhagic shock anticipated and intensified the retention of carbon dioxide and respiratory acidosis during manual jet ventilation through needle cricothyroidotomy in comparison with animals with jet ventilation but without shock. The results found in this work should be considered in future protocols for the assistance of victims of trauma in prehospital settings.
