The lack of evidence-based recommendations for Cesarean delivery under general anesthesia can lead to practice variability and morbidity, particularly concerning the use of opioids. The goal of this study was to describe the practice for Cesarean delivery performed under general anesthesia and identify predictive factors for opioid use at anesthesia induction and the need for neonatal resuscitation. ⋯ Hypertensive disorders of pregnancy were not predictors of opioid use and opioid use was not a predictor of neonatal resuscitation. This suggests opioids could be used for maternal indications.

Electrically evoked and spontaneous neural activity in the subthalamic nucleus under general anesthesia.
Deep brain stimulation (DBS) surgery is commonly performed with the patient awake to facilitate assessments of electrode positioning. However, awake neurosurgery can be a barrier to patients receiving DBS. Electrode implantation can be performed with the patient under general anesthesia (GA) using intraoperative imaging, although such techniques are not widely available. Electrophysiological features can also aid in the identification of target neural regions and provide functional evidence of electrode placement. Here we assess the presence and positional variation under GA of spontaneous beta and high-frequency oscillation (HFO) activity, and evoked resonant neural activity (ERNA), a novel evoked response localized to the subthalamic nucleus. ⋯ ERNA is a robust electrophysiological signal localized to the dorsal subthalamic nucleus subregion that is largely preserved under GA, indicating it could feasibly guide electrode implantation, either alone or in complementary use with existing methods.

ReviewAnesthetic considerations for endovascular treatment in stroke therapy.
The introduction of clot removement by endovascular treatment (EVT) in 2015 has improved the clinical outcome of patients with acute ischemic stroke (AIS) due to a large vessel occlusion (LVO). Anesthetic strategies during EVT vary widely between hospitals, with some departments employing local anesthesia (LA), others performing conscious sedation (CS) or general anesthesia (GA). The optimal anesthetic strategy remains debated. This review will describe the effects of anesthetic strategy on clinical and radiological outcomes and hemodynamic parameters in patients with AIS undergoing EVT. ⋯ The optimal anesthetic approach in patients undergoing EVT for stroke therapy is still unclear, but based on logistics and peri-procedural hemodynamics, LA may be the optimal choice. Multicenter RCTs are warranted comparing LA, CS and GS with strict blood pressure targets and use of the same anesthetic agents to minimize confounding variables.

Many procedures in science and medicine involve the use of a syringe, and its invention is a key milestone in general and regional anesthesia history. The end of the 19th century brought major changes in syringe production. ⋯ This article provides examples of "odd" syringe designs for use in medicine, general anesthesia, and regional anesthesia. Some designs proved functional and have stood the test of time; others quickly disappeared and ended up in dusty collections.

Patient and Operative Factors Associated with Unanticipated Intensive Care Admission and Outcomes Following Posterior Fossa Decompressions in Children: A Retrospective Study.
Posterior fossa decompression for Chiari I Malformation is a common pediatric neurosurgical procedure. We sought to identify the impact of anesthesia-related intraoperative complications on unanticipated admission to the intensive care unit and outcomes following posterior fossa decompression. ⋯ Our study demonstrates that although anesthesia-related intraoperative complications during posterior fossa decompression are infrequent, they are associated with an increased risk of an unanticipated admission to the intensive care unit.
