Randomized Controlled TrialComparison between the effects of normal saline with and without heparin for the prevention and management of arterial catheter occlusion: a triple-blinded randomized trial.
We aimed to compare the effects of saline with and without heparin on the catheter-occlusion rate and coagulation-related blood test results for the management of arterial catheters among patients admitted to a short-term intensive care unit postoperatively. ⋯ Normal saline with and without heparin showed similar efficiency for both the prevention of occlusion and the results of coagulation.

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.

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.
