Time-weighted hyperphosphatemia may be associated with increased mortality in mechanically ventilated patients with severe sepsis or septic shock. However, time-weighted hypo- and hyperphosphatemia were associated with decreased duration of mechanical ventilation. Future studies should further describe the impact of hypo- and hyperphosphatemia on clinical outcomes among critically ill patients with severe sepsis or septic shock.

Severe hypotension and bradycardia occur at similar prevalence in neurocritical care patients who receive dexmedetomidine or propofol. Providers should similarly consider the likelihood of hypotension or bradycardia before starting either sedative.
