Observational Study
Intra-abdominal hypertension in postoperative cardiac surgery patients.
To investigate screening variables identifying patients at risk of developing intra-abdominal hypertension (IAH) after cardiac surgery. ⋯ A set of screening criteria routinely available within the first 24 hours of admission to the ICU after cardiac surgery could correctly identify most patients at risk of IAH.

The Crystalloid versus Hydroxyethyl Starch Trial (CHEST) and the Scandinavian Starch in Severe Sepsis/ Septic Shock (6S) trial reported that 6% hydroxyethyl starch (HES) is associated with increased use of renal replacement therapy and death in critically ill patients. Data collection was harmonised between the two trials in order to facilitate a preplanned individual patient data meta-analysis (IPDMA) of patients with severe sepsis. ⋯ We developed a preanalysis SAP to combine data on patients with severe sepsis from the 6S trial and the CHEST. Prepublication of our SAP will reduce the risk of bias in the reporting of the results and improve confidence in the estimates of effects, allowing comparisons with conventional meta-analyses and assisting in the translation of research findings into clinical practice.

Randomized Controlled Trial
Randomised trial of software algorithm driven regional citrate anticoagulation versus heparin in continuous renal replacement therapy: the Filter Life in Renal Replacement Therapy pilot trial.
The effectiveness of continuous renal replacement therapy (CRRT) increases when unplanned circuit failure is prevented. Adequate anticoagulation is an important component. Although heparin is the predominating anticoagulant, calcium chelation with citrate is an alternative, but systemic calcium monitoring and supplementation increase the complexity of CRRT. We assessed efficacy and safety of citrate delivery via integrated software algorithms against an established regional heparin protocol. ⋯ Although the per-protocol results favoured citrate when it was actually delivered, the significant crossover between treatment arms hampered more definitive conclusions. Until further studies support improved patient outcomes, increased complexity and complications suggest that anticoagulation choice be made using patient-specific indications.
