Multicenter StudyDrug Calculation Errors in Anesthesiology Residents and Faculty: An Analysis of Contributing Factors.
Limited data exist regarding computational drug error rates in anesthesia residents and faculty. We investigated the frequency and magnitude of computational errors in a sample of anesthesia residents and faculty. ⋯ Anesthesiology residents and faculty erred frequently on a computational test, with junior residents and faculty with more experience committing errors more frequently. Residents committed more serious errors twice as frequently as faculty.

A Contemporary Analysis of Medicolegal Issues in Obstetric Anesthesia Between 2005 and 2015.
Detailed reviews of closed malpractice claims have provided insights into the most common events resulting in litigation and helped improve anesthesia care. In the past 10 years, there have been multiple safety advancements in the practice of obstetric anesthesia. We investigated the relationship among contributing factors, patient injuries, and legal outcome by analyzing a contemporary cohort of closed malpractice claims where obstetric anesthesiology was the principal defendant. ⋯ Obstetric anesthesia remains an area of significant malpractice liability. Opportunities for practice improvement in the area of severe maternal injury include timely recognition of high neuraxial block, availability of adequate resuscitative resources, and the use of advanced airway management techniques. Anesthesiologists should avoid delays in maternal care, establish clear communication, and follow their institutional policy regarding neonatal resuscitation. Prevention of maternal neurological injury should be directed toward performing neuraxial techniques at the lowest lumbar spine level possible and prevention/recognition of retained neuraxial devices.

Observational StudyProcedural Challenges During Intubation in Patients With Oropharyngeal Masses: A Prospective Observational Study.
In patients who undergo surgery for oropharyngeal masses, intubation is almost always successful. However, technical aspects of airway management, including bag mask ventilation and oxygenation, may still be difficult. Although rates of airway difficulty and intubation success in these patients have been studied, these data may not reflect difficulty with individual components of the intubation process. We hypothesized that rates of complications with individual elements of the intubation process would not be reflected in the rate of eventual intubation success. To test our hypothesis, we observed the process of airway management and resulting complications with oxygenation and bag mask ventilation in patients with oropharyngeal masses undergoing otorhinolaryngology procedures under general anesthesia. ⋯ We found that, although all patients were successfully intubated, clinicians frequently encountered complications with both intubation and mask ventilation. These complications required frequent use of additional manual maneuvers during mask ventilation and a high incidence of oxygen desaturation. The difficulty of airway management in patients with oropharyngeal masses may not be effectively assessed by success rate alone.

Observational StudyElevated Presepsin Is Associated With Perioperative Major Adverse Cardiovascular and Cerebrovascular Complications in Elevated-Risk Patients Undergoing Noncardiac Surgery: The Leukocytes and Cardiovascular Perioperative Events Study.
Perioperative major adverse cardiovascular and cerebrovascular events (MACCEs) are incompletely understood, and risk prediction is imprecise. Atherogenic leukocytes are crucial in cardiovascular events. However, it is unclear if surgical interventions affect leukocyte counts or activation status. Therefore, we investigated whether noncardiac surgery in patients with elevated cardiovascular risk is associated with changes in atherogenic leukocyte subsets and if these changes are related to perioperative MACCEs. ⋯ Noncardiac surgery was associated with an increase in atherogenic leukocyte subsets. In a post hoc analysis, elevated pre-OP presepsin was associated with MACCE and improved NT-proBNP-based risk assessment. After validation in an independent data set, a presepsin cutoff of 184 pg·mL might qualify to complement NT-proBNP-based risk prediction, thereby increasing the proportion of correctly identified high-risk patients.

Normal Saline and Dextrose 5% in Water Do Not Support Bacterial Growth 24 Hours After Being Spiked in the Perioperative Environment.
The Joint Commission requirement is that the US Pharmacopeia Chapter <797> is followed, which recommends that administration of compounded sterile preparations should begin no later than 1 hour after their preparation. We hypothesized that simply spiking the IV fluid in a nonsterile environment does not pose an increased risk of infection to the patient. ⋯ No bacterial growth was noted in any of the 257 samples collected. Normal saline and dextrose 5% in water do not support bacterial growth 24 hours after their preparation using standard sterile techniques in the perioperative space.
