Analyzing 50,481 victims of prolonged mechanical ventilation in Taiwan 1997-2007, Hung et al report outcomes were frankly terrible, with median survival of about 4 months. Those with a primary indication of neurologic damage fared significantly better. Those with a PMV indication of COPD, younger than 85, had 6-18 months median survival. Authors take the additional [… read more]

An excess amount of the chaos and stress endemic to ICUs is due to poor systems engineering (think alarm fatigue); a rational, integrated approach to design & technology selection is needed to make ICUs more effective and safer for patients, argue Mathews & Pronovost. Academic health systems should fill the leadership vacuum, organize stakeholders and [… read more]

Sadaka et al add their two cents and a cohort study to the Xigris efficacy/safety debate. In their retrospective, propensity-matched analysis of 563 patients sourced from the Project IMPACT database, the 108 who received activated protein C had 35% mortality, vs 54% for the 108 who did not (p=0.005). There were unusually low rates of [… read more]

The EMShockNet team previously claimed in JAMA that hyperoxia (paO2>300) after cardiac arrest could be deadly (63% in-hospital mortality vs 45% in normoxic patients). After looking at 12,108 database records in Australia/New Zealand, Bellomo et al beg to differ. By applying severity of illness/propensity models, they found no increased risk of death in those with [… read more]

THIS STUDY HAS BEEN RETRACTED. Kupfer et al looked retrospectively at 168 vented patients with transudative pleural effusions at Maimonides in Brooklyn. The half that got chest tubes (with an average of 1,200 mL drained) spent 3.8 days on the vent, vs 6.5 days for the group that got only thoracentesis, with no complications reported. [… read more]

Cochrane systematic review and meta-analysis: Pooling 11 randomized trials, n=1,971, Blackwood et al suggested there are some benefits to using a standardized weaning protocol. There was a reduction in weaning and ventilation time in the groups that had weaning protocols; we won’t report them here, because they would be misleading in this small space. They [… read more]

Sacanella et al prospectively observed 230 generally healthy, cognitively intact, highly functional & independently living Spaniards 65 years or older (mean age 75) after urgent admission to a single MICU. About half received mechanical ventilation (54%). Seventy died in-hospital; 48 died within a year, for a one-year survival of 49%. But among the 112 survivors, [… read more]

Roquilly et ses amis francais randomized 150 critically ill victims of severe French trauma to hydrocortisone or placebo for 7 days. The treated group had an absolute 16-19% lower risk for hospital-acquired pneumonia, the primary endpoint (36% vs. 51-54% depending on which intention-to-treat analysis you prefer, p=0.007 to 0.01). (n=150). JAMA 2011;305:1201-1209.

Fernandez-Cerrano et al randomized 56 people with CAP in Spain (only 3 needed mechanical ventilation) to receive methylprednisolone bolus-and-taper or placebo, in addition to ceftriaxone and levofloxacin. The steroid-treated group had less hypoxemia (lower PaO2/FiO2). (n=56). Critical Care 2011;15:R96.

In a rare encouraging positive study in the chronically critically ill, 71% of vent-dependent patients (~6 weeks on MV) who did multiple sets of daily inspirations backwards through a PEEP valve weaned from mechanical ventilation (defined as >72 hrs off the vent), vs. 47% receiving a sham treatment. MIP also improved by 10 cmH2O in [… read more]
