Is there a difference between strong ion gap in healthy volunteers and intensive care unit patients?
Abnormalities of strong ion gap (SIG) are common in critically ill intensive care unit (ICU) patients in conjunction with a high incidence of acid-base abnormalities. However, it is unknown whether abnormalities in SIG are also seen in ICU patients without active acid-base abnormalities. Thus, we conducted this pilot study to examine differences in quantitative acid-base variables between healthy adult volunteers and stable ICU patients with no suspected acid-base abnormalities. ⋯ Stable ICU patients have much higher levels of unexplained anions when comparing with healthy controls. Whether this finding represents occult acid-base disorders or simply metabolic differences among the critically ill is uncertain. Further study in larger populations is warranted to establish the significance of high SIG in otherwise stable ICU patients.

Combination of high frequency oscillatory ventilation and interventional lung assist in severe acute respiratory distress syndrome.
The combination of high-frequency oscillatory ventilation (HFOV) and extracorporeal carbon dioxide removal with the interventional lung assist (iLA) in severe acute respiratory distress syndrome (ARDS) represents a novel treatment option. ⋯ The combination of HFOV/iLA is an option in severe pulmonary failure if conventional ventilation fails and pumpdriven extracorporeal membrane oxygenation therapy is not available.

Review Meta AnalysisCorticosteroid therapy for acute lung injury, acute respiratory distress syndrome, and severe pneumonia: a meta-analysis of randomized controlled trials.
Randomized trials investigating the effect of corticosteroids in the treatment of acute lung injury, acute respiratory distress syndrome, and severe pneumonia have had mixed results. We sought to determine whether systemic corticosteroids reduce hospital mortality from these illnesses. ⋯ Low-dose corticosteroids administered within 14 days of disease onset may reduce all-cause mortality in patients with acute lung injury, acute respiratory distress syndrome, and severe pneumonia. However, the overall quality of the evidence precludes definitive conclusions regarding the use of corticosteroids in this population.

ReviewWhole-body ultrasound in the intensive care unit: a new role for an aged technique.
Management of critically ill patients requires rapid and safe diagnostic techniques. Ultrasonography has become an indispensable tool that supplements physical examination in the intensive care unit. ⋯ Furthermore, it detects possible infectious sites and renders therapeutic invasive procedures more convenient and less complicated. Whole-body ultrasound in the hands of adequately trained intensivists has the ability to reinvigorate the physical examination, without subjecting the patient to excessive irradiation and the risks of transport.

Postobstructive pulmonary edema (POPE; also known as negative pressure pulmonary edema) is a potentially life-threatening complication in which pulmonary edema occurs shortly after the relief of an upper airway obstruction. The incidence of POPE has been reported to be as high as 1 in 1000 general anesthetic cases and commonly presents as acute respiratory distress that requires immediate intervention. This review examines the 2 subclasses of POPE and describes the etiologic factors, pathophysiology, clinical manifestations, diagnostic criteria, and treatment strategies associated with each. The aim of this review was to equip clinicians with the knowledge base necessary to identify patients at increased risk for POPE and to expeditiously diagnose and treat this potentially catastrophic complication.
