Randomized Controlled TrialComparison of ultrasound-guided supraclavicular and costoclavicular brachial plexus blocks in pediatric patients: a randomized clinical trial.
Costoclavicular brachial plexus block has been described recently as a new technique in adults and pediatric patients. In this study, we aimed to compare the supraclavicular and costoclavicular approaches, which are claimed to be effective and practical in pediatric patients. ⋯ Although costoclavicular block did not show superiority in pain management, the block performance was perceived as more practical than supraclavicular block. We believe that costoclavicular brachial plexus block stands as a good option in upper extremity surgeries with the advantages of shorter block performance time and reduced ipsilateral hemidiaphragm paralysis risk in pediatric patients.

Effect of remimazolam on the incidence of delirium after transcatheter aortic valve implantation under general anesthesia: a retrospective exploratory study.
Delirium after transcatheter aortic valve implantation (TAVI) should be prevented because it is associated with worse patient outcomes. Perioperative administration of benzodiazepines is a risk factor for postoperative delirium; however, the association between remimazolam, a newer ultrashort-acting benzodiazepine for general anesthesia, and postoperative delirium remains unclear. This study aimed to evaluate whether remimazolam administration during TAVI under general anesthesia affected the incidence of postoperative delirium. ⋯ Remimazolam may benefit TF-TAVI in terms of postoperative delirium; however, its usefulness must be further evaluated in extensive prospective studies.

Effect of repeated transforaminal epidural low-dose dexamethasone injections on glucose profiles of diabetic and non-diabetic patients with low back pain.
We aimed to investigate the effect of repeated transforaminal epidural low-dose dexamethasone injections on glucose profiles and pituitary-adrenal axis functions of diabetic and non-diabetic patients with low back pain. ⋯ Repeated transforaminal epidural low-dose dexamethasone injections provided no significant elevations in blood glucose or suppression of the pituitary-adrenal axis for two months from the first injection in both diabetic and non-diabetic patients. Our results indicate the intermediate-term safety of repeated transforaminal epidural low-dose dexamethasone injections with regard to the effect on glucose profile and pituitary-adrenal axis functions.

Clinical TrialEfficacy of an aerosol suction device Free-100 M in removing aerosols produced by coughing to minimize COVID-19 infection.
The healthcare workers are at the greatest risk of being exposed to viral infection during airway management of a patient with coronavirus disease 2019 (COVID-19). An air extractor which suctions air around the patient's face would reduce the spread of viral aerosols during coughing, but no study has confirmed this. We assessed whether or not an air extractor reduces the amount of aerosols spreading toward the operator's face, during coughing of simulated patients. ⋯ The Free-100 M air extractor would reduce, but do not remove all, aerosols produced by coughing of a patient, and thus may reduce the risk of infection of COVID-19.

Observational StudyRespiratory depression following cesarean section with single-shot spinal with 100 μg morphine.
Little evidence is available regarding bradypnea measured using continuous monitoring following cesarean section. We aimed to evaluate the rate of cumulative bradypnea time (total bradypnea time/total monitoring time) and its related factors in these parturients. ⋯ After cesarean section was performed with 0.1 mg intrathecal morphine, respiratory depression events were commonly observed. However, the rate of cumulative bradypnea time was very low and there were no related factors.
