NMB in Early ARDS.

A fascinating study from the NEJM.

Neuromuscular Blockers in Early ARDS. Papazian, L et al. NEJM. Vol 6, 12, 2010.

This RCT gave a 48 hr infusion of cis-atricurium to early (<24hrs) ARDS patients. It is the first study to show a mortality difference in this condition since ARDSnet a decade ago (although caution is required as it was underpowered). Whilst it is likely that a large proportion of the population included in this study (early, severe ARDS) will already be on NMB to aid ventilation, there has up until now been an assumption that this therapy was a necessary harm (due to the risk of critical illness polyneuropathy and subsequent slow weaning). This study questions that wisdom, showing both a reduction in adjusted mortality at 90 days (although not at 28) and no increase in the risk of CIPN. The results need to be taken with caution, but are certainly interesting and if confirmed may offer an important advance. There is further detailed analysis of the paper in the presentation ‘Atricurium ARDS’ in the blue box.
