Randomized Controlled Trial Multicenter StudyDexmedetomidine Infusion Versus Placebo During Light or Deep Anesthesia on Postoperative Delirium in Older Patients Undergoing Major Noncardiac Surgery: A Pilot Randomized Factorial Trial.
Postoperative delirium (POD) is common among older surgical patients and may be affected by dexmedetomidine and depth of anesthesia. We designed this pilot study to assess the feasibility of comparing dexmedetomidine with normal saline during light versus deep anesthesia on POD in older patients undergoing major noncardiac surgery. ⋯ The findings of this pilot study demonstrate the feasibility of assessing dexmedetomidine versus placebo during light versus deep anesthesia on POD among older patients undergoing major noncardiac surgery, and justify a multicenter randomized factorial trial.

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.

Clinical Effects and Adverse Events Associated With Desflurane Use in Adult Patients Undergoing Supratentorial Craniotomy: A Systematic Review.
Desflurane is an inhalational anesthetic agent with an appealing recovery profile. The present systematic review investigates the clinical effects and adverse events associated with desflurane use during supratentorial craniotomy for brain tumor resection in adults in comparison with other inhalational and intravenous anesthetic agents. A literature search was conducted across the MEDLINE, Library of Congress and LISTA (EBSCO) databases from January 2001 to January 2021. ⋯ Systemic hemodynamic variables (mean arterial pressure and heart rate) and cerebral hemodynamics (intracranial pressure and cerebrospinal fluid pressure) were comparable between desflurane and other anesthetic agents in each study. The results of this systematic review demonstrate that desflurane is associated with few adverse events when used for anesthesia maintenance in adult patients undergoing supratentorial brain tumor surgery. Large, prospective, comprehensive studies, utilizing standardized parameter evaluation could provide higher levels of evidence to support these findings.

To quantify the rate of low-yield surgery, defined as no high-grade dysplastic precursor lesions or T1N0M0 pancreatic cancer at pathology, during pancreatic cancer surveillance. ⋯ The risk of "low-yield" surgery during pancreatic cancer surveillance is relatively low but should be thoroughly discussed with individuals under surveillance.
