Anesthetic and obstetric predictors of general anesthesia in urgent or emergent Cesarean delivery: a retrospective case-control study.
While regional anesthesia (RA) is considered preferable to general anesthesia (GA) for Cesarean delivery (CD), certain situations necessitate GA. This study reviewed the practice patterns around the use of GA for CD to identify modifiable predictors of GA with the goal of reducing GA rates. ⋯ Abnormal fetal heart rate, specifically bradycardia, was the most common obstetrical indication of GA for urgent/emergent CD, while inadequate neuraxial anesthesia was the most modifiable anesthetic indication. Our data suggest aFHR and cord/fetal prolapse as potentially modifiable risk factors for GA in certain situations.

ReviewUsing multi-level regression to determine associations and estimate causes and effects in clinical anesthesia due to patient, practitioner and hospital or health system practice variability.
In this research methods tutorial of clinical anesthesia, we will explore techniques to estimate the influence of a myriad of factors on patient outcomes. Big data that contain information on patients, treated by individual anesthesiologists and surgical teams, at different hospitals, have an inherent multi-level data structure (Fig. 1). While researchers often attempt to determine the association between patient factors and outcomes, that does not provide clinicians with the whole story. ⋯ In addition, we will explore how to estimate the influence that variability-for example, one anesthesiologist deciding to do one thing, while another takes a different approach-has on outcomes for patients, using the intra-class correlation coefficient for continuous outcomes and the median odds ratio for binary outcomes. From this tutorial, you should acquire a clearer understanding of how to perform and interpret multi-level regression modeling and estimate the influence of variable clinical practices on patient outcomes in order to answer common but complex clinical questions.

Preoperative hypoxic biomarkers and postoperative delirium in patients with obstructive sleep apnea.
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. ⋯ We found a trend of decreasing POD incidence with increasing OSA risk, which was not robust in a complete case analysis. Our results possibly support the phenomenon of hypoxic preconditioning.

Observational StudyUltrasound assessment of the frequency and variation of arteries in the interscalene region.
Given the abundance of arteries in the neck, a significant risk of puncturing arteries exists when performing a brachial plexus block. Therefore, it is important to confirm the presence of arteries when performing a brachial plexus block via the interscalene approach. This study aimed to investigate the frequency and variations of arteries in the interscalene region in healthy Japanese adults using ultrasonography. ⋯ Interscalene observations using ultrasound devices revealed a high artery frequency, with numerous topographic variations.
