Risk Factors for Delayed Extubation Following High Posterior Cervical and Occipital Fusion.
Much has been written on initial airway management in patients undergoing cervical spine procedures, but comparatively less is known about extubation criteria. High cervical and occipital fusion procedures pose a particular risk for extubation given the potential for a reduced range of motion at the occiput-C1 and C1-C2 joints should reintubation be necessary. ⋯ The decision to extubate immediately postoperatively after high cervical and occipital fusion should be considered carefully as the morbidity associated with airway obstruction can be severe in this population, while negative effects of delayed extubation were not evident in our analysis.

Radiographic Predictors of Difficult McGrath MAC Videolaryngoscopy in Patient Undergoing Cervical Spine Surgery.
McGrath MAC videolaryngoscopy is a useful technique for successful intubation in cervical spine-injured patients with manual in-line stabilization of the neck during intubation. We aimed to identify radiographic predictors of difficult McGrath MAC videolaryngoscopy in patient undergoing cervical spine surgery. ⋯ Radiographic variables indicating enlarged tongue relative to the oral cavity and limited neck extension were associated with difficult McGrath MAC videolaryngoscopy in patients undergoing cervical spine surgery with manual in-line cervical stabilization during intubation.

Clinical TrialElectroencephalographic Alpha and Delta Oscillation Dynamics in Response to Increasing Doses of Propofol.
The electroencephalogram (EEG) may be useful for monitoring anesthetic depth and avoiding overdose. We aimed to characterize EEG-recorded brain oscillations during increasing depth of anesthesia in a real-life surgical scenario. We hypothesized that alpha power and coherency will diminish as propofol dose increases between loss of consciousness (LOC) and an EEG burst suppression (BS) pattern. ⋯ We report compelling data regarding EEG patterns associated with increases in propofol dose. This information may more accurately define "therapeutic windows" for anesthesia and provide insights into brain dynamics that are sequentially affected by increased anesthetic doses.

Randomized Controlled TrialThe Effect of Atropine on Trigeminocardiac Reflex-induced Hemodynamic Changes During Therapeutic Compression of the Trigeminal Ganglion.
Percutaneous compression of the trigeminal ganglion (PCTG) can induce significant hemodynamic perturbations secondary to the trigeminocardiac reflex (TCR). The aim of this study was to investigate the effect of atropine pretreatment on hemodynamic responses during PCTG for trigeminal neuralgia. ⋯ Pretreatment with atropine was effective in most patients at minimizing abrupt reduction in HR during PCTG.
