Prevalence of graduated compression stocking-associated pressure injuries in surgical intensive care units.
This study aimed to determine the prevalence of static graduated compression stocking (sGCS)-associated pressure injury among patients in surgical intensive care units (ICUs). ⋯ Pressure injuries are a notable complication of sGCS in surgical ICU patients. Appropriate measures are required to help avoid this potentially preventable harm.

Observational StudyImpact of duration of hypotension prior to norepinephrine initiation in medical intensive care unit patients with septic shock: A prospective observational study.
To determine the impact of duration of hypotension prior to norepinephrine initiation on outcomes in MICU patients with septic shock. We hypothesized increased duration of hypotension prior to norepinephrine initiation would be associated with an increased risk for ICU mortality. ⋯ Duration of hypotension less than one hour and greater than one hour prior to norepinephrine initiation in MICU patients with septic shock is not associated with an increased risk for ICU mortality.

Utility and diagnostic accuracy of bedside lung ultrasonography during medical emergency team (MET) activations for respiratory deterioration.
We investigated the feasibility and diagnostic accuracy of lung ultrasonography during medical emergency team (MET) activations for respiratory deterioration. ⋯ Lung ultrasonography can be rapidly performed in the majority of patients with MET activation for respiratory deterioration. As an independent diagnostic test, lung ultrasonography is non-inferior to the MET clinical assessment and may prevent unnecessary treatments if used simultaneously.

Assessment of corrected flow time in carotid artery via point-of-care ultrasonography: Reference values and the influential factors.
Assessment of Corrected Flow Time (FTc) in carotid artery has been suggested recently as a measure of intravascular volume status. This study aimed to determine the reference values of FTc in carotid artery in a normal population. ⋯ This study would potentially pave the way to determine clinically significant cutoff points in order to assess the diagnostic accuracy of FTc in predicting intravascular volume status and fluid therapy responsiveness.

Abnormal environmental light exposure in the intensive care environment.
We sought to characterize ambient light exposure in the intensive care unit (ICU) environment to identify patterns of light exposure relevant to circadian regulation. ⋯ Patients' environmental light exposure in the intensive care unit is consistently low and follows a diurnal pattern. No effect of nighttime light exposure was observed on melatonin secretion. Inadequate daytime light exposure in the ICU may contribute to abnormal circadian rhythms.
