Preoperative hypoxic biomarkers and postoperative delirium in patients with obstructive sleep apnea.

Purpose: Postoperative delirium (POD) in patients with obstructive sleep apnea (OSA) is associated with increased mortality and healthcare costs. In this study, we investigated the association of OSA risk, serum biomarkers for central nervous ischemia (S100B and NSE), and POD.

Methods: After research ethics approval, patients completed the STOP BANG assessment before undergoing elective surgery.

[Prehospital emergency anesthesia in adults : Current recommendations for performing prehospital emergency anesthesia based on the recommendations for prehospital emergency anesthesia in adults].

The frequency of prehospital emergency anesthesia in Germany is around 2-3% of all emergency medical missions. The Association of the Scientific Medical Societies of Germany (AWMF) has published guidelines for the implementation of a prehospital emergency anesthesia. The purpose of this article is to highlight important aspects from these guidelines and to present the implementation and special features for specific patient groups.

Cognitive function in older patients and their stress challenge using different anesthesia regimes: a single center observational study.

Background: With increasing age older patients are at higher risk for cognitive decline after surgery. Even tailored anesthesia procedures in older patients remain a high risk for postoperative cognitive disorder. Additional stress derived from anxiety and anesthesia itself can negatively impact postoperative cognitive outcomes.

Safety, Utility, and Clinical Results of Continuous Intraoperative Electrophysiologic Monitoring in 1.5T iMRI-Guided Surgery.

Objective: To show that the combined use of intraoperative high-field MRI (iMRI) and electrophysiologic monitoring (IOM) is feasible, safe, and beneficial for patients.

Methods: The setup, surgical, imaging, and clinical results of 110 patients with eloquent intracranial lesions with the combined use of 1.5T iMRI and IOM were analyzed.

Beneficial impact of high-field intraoperative magnetic resonance imaging on the efficacy of pediatric low-grade glioma surgery.

Objective: Intraoperative MRI (iMRI) is assumed to safely improve the extent of resection (EOR) in patients with gliomas. This study focuses on advantages of this imaging technology in elective low-grade glioma (LGG) surgery in pediatric patients.

Methods: The surgical results of conventional and 1.

Resting-state functional MRI in an intraoperative MRI setting: proof of feasibility and correlation to clinical outcome of patients.

OBJECTIVE The authors' aim in this paper is to prove the feasibility of resting-state (RS) functional MRI (fMRI) in an intraoperative setting (iRS-fMRI) and to correlate findings with the clinical condition of patients pre- and postoperatively. METHODS Twelve patients underwent intraoperative MRI-guided resection of lesions in or directly adjacent to the central region and/or pyramidal tract. Intraoperative RS (iRS)-fMRI was performed pre- and intraoperatively and was correlated with patients' postoperative clinical condition, as well as with intraoperative monitoring results.
