ReviewThe 2015 Gerard W. Ostheimer Lecture: What's New in Labor Analgesia and Cesarean Delivery.
Every year the Board of Directors of the Society for Obstetric Anesthesia and Perinatology selects an individual to review the literature pertinent to obstetric anesthesiology published the previous calendar year. This individual selects the most notable contributions, creates a syllabus of the articles, and then presents his/her overview in an annual lecture named in honor of the late Gerard W. Ostheimer, a pioneering obstetric anesthesiologist from the Brigham and Women's Hospital. ⋯ Its contents were presented as the Gerard W. Ostheimer Lecture at the 47th Annual Meeting of the Society for Obstetric Anesthesia and Perinatology, May 16, 2015, in Colorado Springs, Colorado. The syllabus is available as Supplemental Digital Content (http://links.lww.com/AA/B397).

Smoking increases the risk of postoperative morbidity and mortality. Smoking cessation before surgery reduces the risk of complications. The perioperative period may be a "teachable moment" for smoking cessation and provides smokers an opportunity to engage in long-term smoking cessation. ⋯ The "Ask, Advise, Connect" is a practical strategy to be incorporated in the surgical setting. All anesthesiologists should ask their patients about smoking and strongly advise smokers to quit at every visit. Directly connecting patients to existing counseling resources, such as telephone quitlines, family physicians, or pharmacists using fax or electronic referrals, greatly increases the reach and the impact of the intervention.

Long-Term Outcomes for Different Forms of Stress Cardiomyopathy After Surgical Treatment for Subarachnoid Hemorrhage.
Stress-induced cardiomyopathy (SCM) after subarachnoid hemorrhage (SAH) includes predominant apical or basal regional left ventricular dysfunction (RLVD) with concomitant changes in electrocardiogram or increase in cardiac enzymes. We hypothesized that difference in outcome is associated with the type of RLVD after SAH. ⋯ SAH patients with echocardiogram for a clinically indicated reason have a decreased long-term survival, regardless of the presence of RLVD. The association between severe sepsis and SCM-basal warrants future studies to determine their potential synergistic effect on left ventricular systolic dysfunction among SAH patients.

Randomized Controlled TrialActive Warming Utilizing Combined IV Fluid and Forced-Air Warming Decreases Hypothermia and Improves Maternal Comfort During Cesarean Delivery: A Randomized Control Trial.
The aim of this study was to apply both IV fluid and forced-air warming to decrease perioperative hypothermia in women undergoing cesarean delivery with spinal anesthesia. The authors hypothesize that combined-modality active warming (AW) would increase maternal temperature on arrival at the postanesthesia care unit (PACU) and decrease the incidence of maternal perioperative hypothermia (<36°C) compared with no AW. ⋯ Fluid combined with forced-air warming is effective in decreasing the incidence of perioperative hypothermia and improving maternal thermal comfort. However, despite multimodal AW, the majority of women became hypothermic, and shivering was not prevented. The findings suggest that combined AW for cesarean delivery with spinal anesthesia is difficult, and only modest benefit should be expected.

ReviewInflammation and Epidural-Related Maternal Fever: Proposed Mechanisms.
Intrapartum fever is associated with excessive maternal interventions as well as higher neonatal morbidity. Epidural-related maternal fever (ERMF) contributes to the development of intrapartum fever. ⋯ Here, we consider how inflammatory mechanisms may be modulated by local anesthetic agents and their relevance to ERMF. We also critically reappraise the clinical data with regard to emerging concepts that explain how anesthetic drug-induced metabolic dysfunction, with or without activation of the inflammasome, might trigger the release of nonpathogenic, inflammatory molecules (danger-associated molecular patterns) likely to underlie ERMF.
