Crit Care Resusc

The correct renal response to metabolic acidosis should be a negative shift in the urinary strong ion difference ([SID](urinary) = [Na(+)](urinary) + [K(+)](urinary) - [Cl(-)](urinary)). Our hypothesis was that the failure to decrease the [SID](urinary) is frequently present and leads to a more severe metabolic acidosis. ⋯ Most of the critically ill patients with metabolic acidosis showed inappropriate renal compensation, as evidenced by positive [SID](urinary) and higher plasma [Cl(-)]. These patients had more severe metabolic acidosis. On the other hand, patients with adequate renal response and negative [SID](urinary) had positive Δ[AG] - Δ[HCO(3)(-)]. These findings, usually considered as a diagnosis of associated metabolic alkalosis, might be interpreted as the proper renal response to metabolic acidosis.

Case Reports
Emergency use of extracorporeal membrane oxygenation for a foreign body obstructing the airway.
We report on the successful emergency use of extracorporeal membrane oxygenation to provide oxygenation and ventilation to a patient with lifethreatening airway obstruction, and then facilitating the removal of a tracheal food bolus by rigid bronchoscopy.

To identify the resource usage by patients with influenza A H1N1 admitted to Australian and New Zealand intensive care units during the first wave of the pandemic in June, July and August 2009. ⋯ Low rates of admission of H1N1 patients to ICUs during the 2009 pandemic enabled the intensive care system to cope with the large demand when analysed at a jurisdictional level.
-
To evaluate the effect of fluid therapy using Accusol (Baxter Healthcare, McGaw Park, Ill, USA), a crystalloid solution containing sodium bicarbonate and other electrolytes and having a strong ion difference of 35 mEq/L, on acid-base stability after cardiac surgery. ⋯ SBE was more stable in patients treated with Accusol. Further studies are needed to determine whether use of solutions such as Accusol influences important patient outcomes.
-
To assess the frequency of after-hours discharges of patients from the intensive care unit and its effect on in-hospital mortality. ⋯ A high proportion of patients (34.7%) were discharged from the ICU after-hours. Discharge after-hours was associated with a higher risk of in-hospital mortality than discharge during work hours.
