Randomized Controlled Trial Multicenter StudyCombination of Perineural and Wound Infusion After Above Knee Amputation - A randomized, controlled multicenter study.
Post-operative pain after an above-knee amputation is often severe, and in the elderly patients the adverse effects of post-operative opioids are evident. We hypothesized that continuous perineural local anesthetic infusion (CPI) combined to a wound infusion will reduce acute pain and opioid consumption compared to placebo after above knee amputation. ⋯ A combination of continuous perineural and wound local anesthetic infusion seems to diminish the intensity of stump pain after above knee amputation.

Randomized Controlled Trial Multicenter StudyLower versus higher transfusion threshold in septic shock patients of different ages: a study protocol.
Current evidence indicates that it is safe to use a lower haemoglobin (Hb) threshold for red blood cell (RBC) transfusion as compared to a higher Hb-threshold. However, the recent Transfusion Requirements in Cardiac Surgery (TRICS-3) trial reported a significant interaction between patient age and the effect of lower vs higher Hb-thresholds for RBC transfusion. The interaction between patient age and transfusion strategy appears to differ between trials. ⋯ The outlined study will make a detailed assessment of potential interaction of patient age with transfusion strategy in patients with septic shock. This may inform future trials on the benefits and harms of RBC transfusion.

Randomized Controlled Trial Multicenter Study Observational StudyCerebrovascular autoregulation following cardiac arrest: protocol for a post hoc analysis of the randomized COMACARE pilot trial.
Approximately two-thirds of the mortality following out of hospital cardiac arrest is related to devastating neurological injury. Previous small cohort studies have reported an impaired cerebrovascular autoregulation following cardiac arrest, but no studies have assessed the impact of differences in oxygen and carbon dioxide tensions in addition to mean arterial pressure management. ⋯ Cerebrovascular autoregulation is critical to maintain homoeostatic brain perfusion. This study of changes in autoregulation following out of hospital cardiac arrest over the first 48 hours, as compared to data from healthy volunteers, will generate important physiological information that may guide the rationale and design of interventional studies.

Randomized Controlled Trial Multicenter StudyPantoprazole in ICU patients at risk for gastrointestinal bleeding - one-year mortality in the SUP-ICU trial.
The long-term effects of stress ulcer prophylaxis with pantoprazole are unknown in ICU patients. We report 1-year mortality outcome in the Stress Ulcer Prophylaxis in the Intensive Care Unit (SUP-ICU) trial. ⋯ We did not observe a difference in 1-year mortality among acutely admitted adult ICU patients with risk factors for gastrointestinal bleeding allocated to stress ulcer prophylaxis with pantoprazole or placebo during the ICU stay. (The SUP-ICU trial was funded by Innovation Fund Denmark and others; ClinicalTrials.gov number, NCT02467621).

Multicenter StudyGenetic polymorphisms and prediction of chronic post-surgical pain after hysterectomy-a subgroup analysis of a multicenter cohort study.
Chronic post-surgical pain (CPSP) is a serious problem. Clinical and psychological variables have not been able to explain all observed variance in prevalence and severity of CPSP. The first objective is to determine the association between genetic polymorphisms and the prevalence of CPSP after hysterectomy. The second objective is to analyze if the implementation of genetic polymorphisms into a previously performed clinical and psychological predictor analysis on the development of CPSP after hysterectomy will improve its discriminatory power. ⋯ The rs4818 polymorphism within the COMT gene was associated with the prevalence of CPSP 3 months after hysterectomy, but the implementation of rs4818 into the prediction model did not significantly improve the chance of identifying hysterectomy patients at risk for CPSP.
