Assessment of Didactic Transesophageal Echocardiography Education During Anesthesia Residency.

BACKGROUND: Transesophageal echocardiography can be a useful monitor during noncardiac surgery, in patients with comorbidities and/or undergoing procedures associated with substantial hemodynamic changes. The goal of this study was to investigate if transesophageal-echocardiography-related knowledge could be acquired during anesthesia residency. METHODS: After institutional review board approval, a prospective observational study was performed in two anesthesiology residency programs. After a 41-week didactic transesophageal-echocardiography-education curriculum residents' exam scores were compared to baseline. The educators' examination was validated against the National Board of Echocardiography's Examination of Special Competence in Advanced Perioperative Transesophageal Echocardiography. RESULTS: After the 41-week course, clinical anesthesia (CA)-3 exam scores increased 12% compared to baseline (P = .03), CA-2 scores increased 29% (P = .007), and CA-1 scores increased 25% (P = .002). Pearson correlation coefficient between the educators' exam score and the special competence exam percentile rank was 0.69 (P = .006). Pearson correlation coefficient between the educators' exam score and the special competence exam scaled score was 0.71 (P = .0045). CONCLUSIONS: The 41-week course resulted in significant increases in exam scores in all 3 CA-classes. While didactic knowledge can be learned by anesthesiology residents during training, it requires significant time and effort. It is important to educate residents in echocardiography, to prepare them for board examinations and to care for the increasingly older and sicker patient population. Further work needs to be done to determine optimal methods to provide such education.

Which Country is Truly Developed? COVID-19 has Answered the Question.

The developed countries of the world were ill-prepared for the pandemic that they have suffered. When we compare developed to developing countries, the sophisticated parameters we use do not necessarily address the weaknesses in the healthcare systems of developed countries that make them susceptible to crises like the present pandemic. We strongly suggest that better preparation for such events is necessary for a country to be considered developed.

The effect of hemispheric synchronization on intraoperative analgesia.

UNLABELLED: In this double-blinded randomized study, we sought to confirm that patients undergoing general anesthesia who were exposed to a hemispheric synchronization (Hemi-Sync) musical recording during surgery had a smaller analgesia requirement, as was suggested in a previous study. Bispectral index monitoring was used to adjust depth of hypnosis, and hemodynamic variables were used to determine analgesia administration. Consented patients underwent either laparoscopic bariatric or one-level lumbar disk surgery. After endotracheal intubation and application of headphones, baseline heart rate and arterial blood pressure were established. Isoflurane was titrated to maintain sedation on the basis of a target bispectral index range of 40-60, and 25-microg increments of fentanyl were administered in response to increases in heart rate and systolic arterial blood pressure. Bariatric patients who listened to Hemi-Sync required one-third less fentanyl than the control group (mean [SD]: 0.015 [0.01] vs 0.024 microg.kg(-1).min(-1) [0.01]) (P = 0.009). It is interesting to note that lumbar patients in the experimental and control groups required similar amounts of fentanyl (0.012 [0.01] vs 0.015 microg.kg(-1).min(-1) [0.01]). End-tidal isoflurane concentration was similar for Hemi-Sync and blank-tape patients (bariatric, 0.74% (0.14) vs 0.77% (0.21); lumbar, 0.36% [0.16] vs 0.39% [0.12]). The bariatric patients in this study demonstrated that Hemi-Sync may be an innovative intraoperative supplement to analgesia. IMPLICATIONS: The purpose of this study was to determine the decrease in analgesia requirement for patients listening to hemispheric synchronization (musical tones) while under general anesthesia. We demonstrated that bariatric patients who listened to hemispheric synchronization had a smaller analgesia requirement than those who listened to a blank tape.
