The association between sodium fluctuations and mortality in surgical patients requiring intensive care.
Serum sodium derangement is the most common electrolyte disturbance among patients admitted to intensive care. This study aims to validate the association between dysnatremia and serum sodium fluctuation with mortality in surgical intensive care patients. ⋯ We identified 8600 subjects, 39% of whom were female, with a median age of 66years for analysis. Subjects with dysnatremia were more likely to be dead at 28 days (17% vs 7%; P<.001). There was a significant association between sodium fluctuation and mortality at 28 days (adjusted odds ratio per 1mmol/L change, 1.10 [95% confidence interval, 1.08-1.12; P<.001]), even in patients who remained normotremic during their intensive care unit stay (1.12 [95% confidence interval, 1.09-1.16; P<.001]) CONCLUSIONS: This observational study validates previous findings of an association between serum sodium fluctuations and mortality in surgical intensive care patients. This association was also present in subjects who remained normonatremic throughout their intensive care unit admission.

Multicenter StudyClinical variables associated with poor outcome from sepsis-associated acute kidney injury and the relationship with timing of initiation of renal replacement therapy.
Identify clinical variables associated with mortality in patients with sepsis-associated acute kidney injury (SA-AKI) receiving continuous renal replacement therapy (CRRT) and examine timing of initiation of CRRT in reference to those variables identified. ⋯ In patients with SA-AKI, survival is lower when CRRT is started in the setting of low urine output.

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.
