Multicenter StudyAnesthetic Management of Patients With Suspected or Confirmed 2019 Novel Coronavirus Infection During Emergency Procedures.
The aim of the present study was to prevent cross-infection in the operating room during emergency procedures for patients with confirmed or suspected 2019 novel coronavirus (2019-nCoV) by following anesthesia management protocols, and to document clinical- and anesthesia-related characteristics of these patients. ⋯ The present study indicates that COVID 19-specific guidelines for emergency procedures for patients with confirmed or suspected 2019-nCoV may effectively prevent cross-infection in the operating room. Most patients with confirmed or suspected COVID 19 presented with fever and dry cough and demonstrated bilateral multiple mottling and ground-glass opacity on chest computed tomography scans.

Observational StudyA Comparison of Transesophageal to Transthoracic Echocardiographic Measures of Right Ventricular Function.
To assess the concordance between transesophageal echocardiographic (TEE) and transthoracic echocardiograpic (TTE) measures of right ventricular (RV) function using standard 2-dimensional and Doppler methods. The authors hypothesized that there would be significant disagreement in tricuspid annular plane systolic excursion (TAPSE), fractional area change, right-sided index of myocardial performance, and tricuspid annular systolic velocity (S'). ⋯ When performing an assessment of RV function, transesophageal echocardiographers should exercise caution when extrapolating data validated by TTE to TEE studies. Measures of RV function by TEE tend to have fair agreement to TTE measurements obtained in close temporal proximity under similar hemodynamic conditions. Most importantly, the present study showed that TAPSE and S' values obtained from the modified transgastric RV inflow view tend to have lower values than those measured with TTE. Given the propensity for underestimating measurements from the modified transgastric RV inflow view, the authors conclude that values equal to or greater than established norms for tricuspid annular motion may be used to establish normal-but not abnormal-RV function.
