Practice GuidelineAmerican Society for Enhanced Recovery and Perioperative Quality Initiative Joint Consensus Statement on Perioperative Management of Patients on Preoperative Opioid Therapy.
Enhanced recovery pathways have quickly become part of the standard of care for patients undergoing elective surgery, especially in North America and Europe. One of the central tenets of this multidisciplinary approach is the use of multimodal analgesia with opioid-sparing and even opioid-free anesthesia and analgesia. However, the current state is a historically high use of opioids for both appropriate and inappropriate reasons, and patients with chronic opioid use before their surgery represent a common, often difficult-to-manage population for the enhanced recovery providers and health care team at large. ⋯ The overarching theme of this document is to provide health care providers with guidance to reduce potentially avoidable opioid-related complications including opioid dependence (both physical and behavioral), disability, and death. Enhanced recovery programs attempt to incorporate best practices into pathways of care. By presenting the available evidence for perioperative management of patients on opioids, this consensus panel hopes to encourage further development of pathways specific to this high-risk group to mitigate the often unintentional iatrogenic and untoward effects of opioids and to improve perioperative outcomes.

Randomized Controlled Trial Comparative StudyRandomized Trial Comparing Early and Late Administration of Rocuronium Before and After Checking Mask Ventilation in Patients With Normal Airways.
During induction of general anesthesia, it is common practice to delay neuromuscular blockade until the ability to deliver mask ventilation has been confirmed. However, the benefits of this approach have never been scientifically validated. We thus compared the early and late administration of rocuronium before and after checking mask ventilation to investigate the efficiency of mask ventilation and the time to tracheal intubation in patients with normal airways. ⋯ The early administration of rocuronium before checking mask ventilation resulted in a larger mask VT and earlier tracheal intubation than the late administration of rocuronium after checking mask ventilation in patients with normal airways.

Multicenter Study Comparative Study Observational StudyCardiac Structure and Function in Morbidly Obese Parturients: An Echocardiographic Study.
The increasing prevalence of obesity worldwide is a major threat to global health. Cardiac structural and functional changes are well documented for obesity as well as for pregnancy, but there is limited literature on morbidly obese parturients. We hypothesized that there are both cardiac structural and functional differences between morbidly obese pregnant women and pregnant women of normal body mass index (BMI). ⋯ Cardiac index did not differ between obese pregnant women and those with normal BMI. Their increased left ventricular mass and lower stroke volume index could indicate a limited adaptive reserve. Obese women had minor decreases in septal left ventricular tissue Doppler velocity, but the E/E' average values did not suggest clinically significant diastolic dysfunction.

Contemporary Academic Contributions From Anesthesiologists in Adult Critical Care Medicine.
Anesthesiology has a long relationship with critical care medicine (CCM). However, US anesthesiologists are less likely to practice CCM than non-US anesthesiologists. To date, no studies have compared academic contributions in CCM between US anesthesiologists and non-US anesthesiologists. The objective of our study was to use recent trends in critical care publications as a surrogate for academic contribution among US and non-US anesthesiologists. ⋯ When compared to non-US anesthesiologists, US anesthesiologists had more CCM publications in anesthesiology journals and fewer publications in multidisciplinary CCM journals. The number of anesthesiology CCM publications decreased for both US and non-US anesthesiologists throughout the study period.
