Methylprednisolone in patients undergoing cardiopulmonary bypass (SIRS): a randomised, double-blind, placebo-controlled trial
This study is registered with ClinicalTrials.gov, number NCT00427388. Findings Patients were recruited between June 21, 2007, and Dec 19, 2013. Complete 30-day data was available for all 7507 patients randomly assigned to methylprednisolone (n=3755) and to placebo (n=3752). Methylprednisolone, compared with placebo, did not reduce the risk of death at 30 days (154 [4%] vs 177 [5%] patients; relative risk [RR] 0·87, 95% CI 0·70–1·07, p=0·19) or the risk of death or major morbidity (909 [24%] vs 885 [24%]; RR 1·03, 95% CI 0·95–1·11, p=0·52). The most common safety outcomes in the methylprednisolone and placebo g...

The safety of addition of nitrous oxide to general anaesthesia in at-risk patients having major non-cardiac surgery (ENIGMA-II): a randomised, single-blind trial
Publication date: 18–24 October 2014 Source:The Lancet, Volume 384, Issue 9952 Author(s): Paul S Myles , Kate Leslie , Matthew T V Chan , Andrew Forbes , Philip J Peyton , Michael J Paech , W Scott Beattie , Daniel I Sessler , P J Devereaux , Brendan Silbert , Thomas Schricker , Sophie Wallace Background Nitrous oxide is commonly used in general anaesthesia but concerns exist that it might increase perioperative cardiovascular risk. We aimed to gather evidence to establish whether nitrous oxide affects perioperative cardiovascular risk. Methods We did an international, randomised, assessor-blinded trial in patients ag...
