Multicenter Study
Carbon Dioxide, Blood Pressure, and Perioperative Stroke: a Retrospective Case-Control Study.
The relationship between intraoperative physiology and postoperative stroke is incompletely understood. Preliminary data suggest that either hypo- or hypercapnia coupled with reduced cerebrovascular inflow (e.g., due to hypotension) can lead to ischemia. This study tested the hypothesis that the combination of intraoperative hypotension and either hypo- or hypercarbia is associated with postoperative ischemic stroke. ⋯ Intraoperative hypotension and carbon dioxide dysregulation may each independently increase postoperative stroke risk.

Observational Study
"Sedation versus General Anesthesia For Tracheal Intubation In Children With Difficult Airways: A Cohort Study from the Pediatric Difficult Intubation Registry."
Sedated and awake tracheal intubation approaches are considered safest in adults with difficult airways, but little is known about the outcomes of sedated intubations in children. The primary aim of this study was to compare the first-attempt success rate of tracheal intubation during sedated tracheal intubation versus tracheal intubation under general anesthesia. The hypothesis was that sedated intubation would be associated with a lower first-attempt success rate and more complications than general anesthesia. ⋯ Sedation and general anesthesia had a similar rate of first-attempt success of tracheal intubation in children with difficult airways; however, 27.6% of the sedation cases needed to be converted to general anesthesia to complete tracheal intubation. Complications overall were similar between the groups, and the rate of severe complications was low.
