Effect of remimazolam on intraoperative neuromonitoring during thyroid surgery: a case series.
Intraoperative neuromonitoring is widely used to prevent accidental injury during thyroid surgery. Anesthesia should be performed without muscle relaxant or agents with high muscle-relaxant potency. Remimazolam, a novel intravenous anesthetic, became available for clinical use in 2020. ⋯ Intraoperative monitoring was performed without problems and all surgeries were completed without any complications. Anesthesia with remimazolam at the normal dose did not prolong the time to first positive electromyogram in patients undergoing thyroid surgery, and enables intraoperative recurrent laryngeal nerve monitoring to be performed without any serious perioperative adverse events. Remimazolam may provide a comparable quality of anesthesia to that of existing drugs for neuromonitoring during thyroid surgery.

Observational StudyFactors associated with quality of dreams during general anesthesia: a prospective observational study.
Patients frequently report having dreams during general anesthesia, and the dreams are often reported to be pleasant dreams. However, factors associated with the quality of dreams during general anesthesia have not been clarified. The aim of this study was to determine the relationships between the quality of dreams during general anesthesia and perioperative factors. ⋯ A total of 1100 patients were included in the study, and 293 (25.4%) of the patients reported having dreams during anesthesia. Half of the patients who experienced dreams during anesthesia (50.2%, 147/293 patients) reported having a pleasant dream. Multivariate logistic regression analysis revealed that only HADS-depression score of less than 11 was related to pleasant dreams (OR: 3.3 [95% CI 1.3-10.0]).

Assessing volume responsiveness using right ventricular dynamic indicators of preload.
Dynamic indicators of preload currently only do reflect preload requirements of the left ventricle. To date, no dynamic indicators of right ventricular preload have been established. The aim of this study was to calculate dynamic indicators of right ventricular preload and assess their ability to predict ventricular volume responsiveness. ⋯ In our experimental animal setting, calculating dynamic indicators of right ventricular preload is possible and appears promising in predicting volume responsiveness.

Case ReportsGlucose control using an artificial pancreas in a severe COVID-19 patient on extracorporeal membrane oxygenation: a case report.
The usefulness and safety of continuous glucose monitoring (CGM) systems in adult patients with severe coronavirus disease (COVID-19) have been reported. Using CGM might reduce the exposure patients and healthcare workers to COVID-19 and limit the use of personal protective equipment during the pandemic. CGM devices measure glucose in the subcutaneous interstitial fluid, but the accuracy of this technique has not been established in critically ill patients. ⋯ Fifty-six hours after adopting the STG-55, it was removed because the blood sampling failed. No episodes of hypoglycemia were observed despite deep sedation during this period. In conclusion, this case demonstrates the potential utility of an artificial pancreas in patients with severe COVID-19.
