32475761 Here, we report a case of dexmedetomidine use in the setting of worsening hypoxemia, whereby oxygenation improved and intubation was avoided. […] If dexmedetomidine can improve compliance with non-invasive oxygen support (the current recommended first-line therapy) while promoting better oxygenation, it may also decrease the need for mechanical ventilation and thus improve mortality.
32550090 All four patients were on propofol at some point during bradycardia with patients 1, 2, and 3 also receiving dexmedetomidine.
32684211 To compare the therapeutic effects and safety of dexmedetomidine and midazolam on patients with severe coronavirus disease 2019 (COVID-19) who received non-invasive ventilation. […] According to different sedative drugs, patients were divided into the control group (without sedative drugs), dexmedetomidine group and midazolam group. […] Fourteen patients were injected with dexmedetomidine (loading dose of 1 μg/kg for 10 minutes, maintained at 0.2-0.7 μg×kg-1×h-1); 9 patients were injected with midazolam (loading dose of 0.05 mg/kg for 2 minutes, maintained at 0.02-0.10 mg×kg-1×h-1); 12 patients didn’t use sedative drugs due to limitations of previous hospital or patients’ rejection. […] In dexmedetomidine group and midazolam group, the Ramsay score was maintained at 2-3 points after sedation, which were higher than those of control group at different time points after sedation, and there was no significant difference between dexmedetomidine group and midazolam group. […] MAP of dexmedetomidine group and midazolam group decreased gradually after sedation. […] HR decreased gradually after sedation treatment, which was significantly lower after 12 hours of sedation than that before sedation, and HR in dexmedetomidine group was significantly lower than that in control group after 12 hours of sedation (bpm: 84.0±13.9 vs. […] PaO2 in dexmedetomidine group and midazolam group were significantly higher than that in the control group after 12 hours of sedation [cmH2O (1 cmH2O = 0.098 kPa): 79.0±6.5, 79.0±8.9 vs. […] 70.0±7.8, both P < 0.05]; the decreases of RR in dexmedetomidine group and midazolam group were significant than that in control group after 1 hour of sedation (bpm: 34.0±3.9, 33.8±4.6 vs. […] There were no differences of MAP, HR, PaO2 and RR between dexmedetomidine group and midazolam group at different time points. […] The sleep duration in dexmedetomidine group and midazolam group were significantly longer than that in the control group (hours: 4.9±1.9, 5.8±2.4 vs. […] 3.0±1.8, both P < 0.05), but there was no difference between dexmedetomidine group and midazolam group (P > 0.05). […] In dexmedetomidine group, there were 2 cases of bradycardia, 1 case of intubation due to refractory hypoxemia. […] Dexmedetomidine is more effective and safer than midazolam in these patients, but attention should be paid to HR and blood pressure monitoring.
32733668 As compared with placebo, significant benefits emerged for quetiapine and dexmedetomidine in intensive care unit (ICU) settings, and for none of the medications in non-ICU settings.
32947292 Light sedation was administered with dexmedetomidine. […] Dexmedetomidine was used in all PP sessions.
32984835 To present three patients with severe coronavirus disease 2019 infection who developed life-threatening hyperpyrexia while being treated with dexmedetomidine for sedation. […] All developed hyperpyrexia, defined as a temperature above 41.1°C, following an increase in dexmedetomidine dosing to above 1.5 µg/kg/hr. […] Fevers resolved following discontinuation of dexmedetomidine. […] While the exact mechanism of hyperpyrexia remains unclear, findings in this study suggest that high doses of dexmedetomidine infusion are associated with hyperpyrexia in a seemingly dose-dependent fashion in critically ill patients with coronavirus disease 2019. […] Dexmedetomidine, a centrally acting alpha-2 agonist, may alter hypothalamic temperature regulation through disturbances in neurotransmitter expression and metabolism. […] We postulate that the use of high-dose dexmedetomidine in a hyperinflammatory state may increase the risk of developing hyperpyrexia in this severe disease state.
