Evaluating a Novel EEG-Based Index for Stroke Detection Under Anesthesia During Mechanical Thrombectomy.
The rapid identification of acute stroke (AS) during and after anesthesia might lead to early interventions and improved outcomes. We investigated a novel 2-channel electroencephalogram (EEG)-based marker for stroke detection-the lateral interconnection ratio (LIR)-in AS patients having endovascular thrombectomy (EVT) with general anesthesia (GA) or sedation. The LIR in 2 reference groups of patients without postoperative neurological complications was used for comparison. ⋯ We demonstrated the utility of using AS patients undergoing EVT as a platform for assessing a novel EEG marker for the identification of stroke during anesthesia. Further, large-scale studies in AS patients during EVT and in patients undergoing different surgeries and anesthesia are required to validate the LIR.

Early Extubation After Elective Infratentorial Craniotomy: Results of the International PRICE Survey.
Early extubation, defined as removal of the endotracheal tube at the end of surgery before transfer to a designated postoperative care area, is associated with better outcomes after elective infratentorial craniotomy. The Predicting Infratentorial Craniotomy Extubation (PRICE) project was an international survey designed to estimate the rate of early extubation after elective infratentorial craniotomy, as reported by neuroanesthesiologists, neurosurgeons, and neurocritical care specialists. ⋯ The reported rate of early extubation after elective infratentorial craniotomy varies widely between institutions, with respondents from high-volume institutions reporting greater rates of early extubation than those from lower-volume centers. The course of surgery, evidence of bulbar dysfunction, and altered consciousness, appear to affect the decision to extubate early more than other predictors.

Factors Associated With Unplanned Post-Craniotomy Re-intubation in Children: A NSQIP-Pediatric® Analysis.
Most children undergoing craniotomy with general endotracheal anesthesia are extubated postoperatively, but some require unplanned postoperative intubation (UPI). We sought to determine the incidence of UPI and identify associated factors and related postoperative mortality. ⋯ Although uncommon, UPI in children who underwent craniotomy was associated with an elevated risk of postoperative mortality. The presence of identifiable risk factors may be used for preoperative counseling and risk profiling in these patients.
