I Tweet, Therefore I Learn: An Analysis of Twitter Use Across Anesthesiology Conferences.
Twitter in anesthesiology conferences promotes rapid science dissemination, global audience participation, and real-time updates of simultaneous sessions. We designed this study to determine if an association exists between conference attendance/registration and 4 defined Twitter metrics. ⋯ We observed that the number of Twitter participants for a conference is positively associated with Twitter activity metrics. No relationship between conference size and Twitter metrics was observed. Physician influencers may be an important driver of participants.

Observational StudyBody Position Alters Mechanical Power and Respiratory Mechanics During Thoracic Surgery.
During thoracic surgery, patients are usually positioned in lateral decubitus and only the dependent lung ventilated. The ventilated lung is thus exposed to the weight of the contralateral hemithorax and restriction of the dependent chest wall. We hypothesized that mechanical power would increase during one-lung ventilation in the lateral position. ⋯ Mechanical power and lung elastance are increased in the lateral position with one-lung ventilation. Esophageal pressure monitoring may be used to follow these changes.

A Novel 3-Dimensional Approach for the Echocardiographic Evaluation of Mitral Valve Area After Repair for Degenerative Disease.
Currently available 2-dimensional (2D) echocardiographic methods for accurately assessing the mitral valve orifice area (MVA) after mitral valve repair (MVr) are limited due to its complex 3-dimensional (3D) geometry. We compared repaired MVAs obtained with commonly used 2D and 3D echocardiographic methods to a 3D orifice area (3DOA), which is a novel echocardiographic measurement and independent of geometric assumptions. ⋯ Post-MVr MVAs obtained using the novel 3DOA method were significantly smaller than those obtained by conventional echocardiographic methods and may be consistent with a higher incidence of MVA reduction when compared to 2D techniques. Further studies are still needed to establish the clinical significance of 3D echocardiographic techniques used to measure MVA after MVr.

A Cross-Sectional Survey to Determine the Prevalence of Burnout Syndrome Among Anesthesia Providers in Zambian Hospitals.
Burnout is a psychological syndrome that results from chronic exposure to job stress. It is defined by a triad of emotional exhaustion, depersonalization, and reduced personal accomplishment. In research, mostly from high-income countries, burnout is common in health care professionals, especially in anesthesiologists. Burnout can negatively impact patient safety, the physical and mental health of the anesthetist, and institutional efficiency. However, data on burnout for anesthesia providers in low- and middle-income countries are poorly described. This study sought to determine the prevalence of burnout syndrome among all anesthesia providers (physician and nonphysician) working in Zambian hospitals and to determine which sociodemographic and occupational factors were associated with burnout. ⋯ In a cross-sectional survey of anesthesia providers in Zambia, >50% of the respondents met the criteria for burnout. The risk was particularly high among nonphysician providers who typically work in isolated rural practice. Efforts to decrease burnout rates through policy and educational initiatives to increase the quantity and quality of training for anesthesia providers should be considered.
