Comparative StudyPlasma procalcitonin and C-reactive protein in acute septic shock: clinical and biological correlates.
To determine the relationship between plasma procalcitonin (PCT) levels, C-reactive protein (CRP), white blood cell count (WBC), ionized calcium (Ca2+), and patient outcome; and to compare the diagnostic and prognostic information provided by PCT and by CRP. ⋯ PCT levels were correlated with the severity of disease at onset (APACHE II) and inflammation (CRP) but not with Ca2+ levels. Inaugural PCT or CRP levels per se poorly predicted outcome but decreasing levels were associated with a higher probability of survival. In this respect, PCT was found to be an earlier marker than CRP.

The role of tracheostomy in burn patients is controversial. Previous studies, primarily in adults, suggested that severely burned patients with tracheostomies have a higher incidence of tracheostomy site infections, mortality, and pneumonia. The purpose of this study is to determine the safety and efficacy of early tracheostomy in severely burned children. ⋯ Early tracheostomy in severely burned children is safe and effective. It provides a secure airway and may result in improvement in ventilator management for these children.

Very early extubation of children after cardiac surgery has been suggested as a safe alternative to prolonged postoperative intubation but is still not common practice. Studies of early extubation in children may not have described reasons for failure to extubate, or have included nonbypass or only low-risk repairs. We present our experience with very early extubation in an inclusive group of children after cardiac surgery. ⋯ Successful early extubation of even young children is possible and easily accomplished in most children undergoing cardiopulmonary bypass, even with complex procedures, but advantages of extubation in the operating room vs. immediate ICU extubation remain unclear. Transient mild-to-moderate mixed acidosis is common and requires no treatment. Full implementation requires acceptance by surgical and ICU staffs.

Randomized Controlled Trial Multicenter Study Clinical TrialFluid thresholds and outcome from severe brain injury.
To determine, by retrospective analysis, critical thresholds for intracranial pressure, mean arterial pressure, cerebral perfusion pressure, and fluid balance associated with poor outcome in patients with severe brain injury. ⋯ Exceeding thresholds of intracranial pressure, mean arterial pressure, cerebral perfusion pressure, and fluid volume may be detrimental to severe brain injury outcome. Fluid balance lower than -594 mL was associated with an adverse effect on outcome, independent of its relationship to intracranial pressure, mean arterial pressure, or cerebral perfusion pressure.
