Preeclampsia is a common condition of pregnancy characterized by hypertension complicated by cerebral, cardiac, hepatic, renal, hematologic, and placental dysfunction. Patients with preeclampsia frequently undergo cesarean delivery, the most common major surgical procedure in the world. ⋯ Preeclampsia-specific resuscitation, individualized fluid administration, safe neuraxial and general anesthesia, and management of intraoperative bleeding are discussed along with strategies for postoperative analgesia, thromboprophylaxis, and antihypertensive agents in patients who breastfeed. This review discusses recently recognized postoperative deterioration in maternal mental health, the possibility of myocardial injury after cesarean delivery, and the need for long-term cardiometabolic follow-up.

Electroencephalogram burst suppression can be associated with postoperative delirium; however, the results of relevant studies are discrepant. This systematic review and meta-analysis aimed to assess the association between intraoperative burst suppression and postoperative delirium in adult surgical patients. ⋯ The meta-analysis suggests an association between intraoperative burst suppression and postoperative delirium; however, the quality of evidence was very low. The limited number of studies and substantial heterogeneity across them emphasize the need for further high-quality studies to establish a more robust conclusion.

Continuous improvement of quality and safety is a professional obligation of anesthesiologists and an ongoing activity of all academic departments and private practices. Quality improvement is an infinite process that is never fully complete but that instead evolves over time in response to emerging threats to patient safety from new medications, new surgical procedures, and increased recognition of systematic threats. This review discusses current definitions and thinking in anesthesia quality improvement, outlines recommended efforts at the local department level, and makes suggestions for the projects and activities most likely to benefit the anesthesia patients and clinicians of the future.

Lumbar cerebrospinal fluid (CSF) drainage is one of the few preventative and therapeutic practices that may reduce spinal cord ischemia in high-risk thoracic endovascular aortic aneurysm repair (TEVAR). Although this is part of clinical guidelines in open thoracoabdominal aortic repair, there are no randomized controlled trials that provide convincing evidence on the protection conferred by CSF drainage in high-risk TEVAR patients. ⋯ The current literature is inconclusive and provides conflicting results regarding the efficacy of, and complications from, CSF drainage in TEVAR. Filling the knowledge gap resulting from the limited current state of the literature warrants additional high-quality randomized controlled clinical trials that balance CSF drainage efficacy with potential complications in high-risk TEVAR patients.

Most of science involves making observations, forming hypotheses, and testing those hypotheses, to form valid conclusions. However, a distinct, longstanding, and very productive scientific approach does not follow this paradigm; rather, it begins with a screen through a random collection of drugs or genetic variations for a particular effect or phenotype. ⋯ This review explains the rational for forward screening approaches and uses examples of screens for mutants with altered anesthetic sensitivities and for novel anesthetics to illustrate the methods and impact of the approach. Forward screening approaches are becoming even more powerful with advances in bioinformatics aided by artificial intelligence.
