Randomized Controlled Trial Multicenter StudyEfficacy and safety of a 72-h infusion of prostacyclin (1 ng/kg/min) in mechanically ventilated patients with pulmonary infection and endotheliopathy-protocol for the multicenter randomized, placebo-controlled, blinded, investigator-initiated COMBAT-ARF trial.
Acute respiratory failure (ARF) is common in critically ill patients, and 50% of patients in intensive care units require mechanical ventilation [3, 4]. The COVID-19 pandemic revealed that COVID-19 infection induced ARF caused by damage to the microvascular pulmonary endothelium. In a randomized clinical trial, mechanically ventilated COVID-19 patients with severe endotheliopathy, as defined by soluble thrombomodulin (sTM) ≥ 4 ng/mL, were randomized to evaluate the effect of a 72-h infusion of low-dose prostacyclin 1 ng/kg/min or placebo. Twenty-eight-day mortality was 21.9% versus 43.6% in the prostacyclin and the placebo groups, respectively (RR 0.50; CI 0.24 to 0.96 p = .06). The aim of the current trial is to investigate if this beneficial effect and safety of prostacyclin also are present in any patient with suspected pulmonary infection requiring mechanical ventilation and concomitant severe endotheliopathy. ⋯ This trial will investigate the efficacy and safety of prostacyclin vs. placebo for 72-hours in mechanically ventilated patients with any suspected pulmonary infection and severe endotheliopathy, as defined by sTM ≥4 ng/mL. Trial endpoints focus on the potential effect of prostacyclin to reduce 28-day all-cause mortality.

Randomized Controlled TrialEffect of individualized anesthesia and analgesia on postoperative pain in patients stratified for pain sensitivity: A study protocol for the PeriOPerative individualization trial randomized controlled trial.
Despite advancements in surgical and anesthesia techniques, acute and persistent postoperative pain are still a common challenge. Postoperative pain has direct effects on individual patient care and outcome, as well as putting strain on limited health care resources. Several prediction methods for postoperative pain have been described. One such method is the assessment of pain during peripheral venous cannulation (VCP). It is not known if different approaches to anesthesia and analgesia, depending on the evaluation of risk for postoperative pain, can improve outcome. The aim of this study is to evaluate if individualized anesthesia and analgesia can affect postoperative pain and recovery after surgery, in patients stratified by VCP. ⋯ Individualized perioperative pain management has the potential to improve patient care. This study will examine the impact of different anesthesia and analgesia regimes, in patients with differing pain sensitivity, on postoperative pain.

Randomized Controlled Trial Comparative StudyCocaine versus xylometazoline to prevent epistaxis after nasotracheal intubation: A randomized trial.
Nasotracheal intubation is associated with a risk of epistaxis. Several drugs, including cocaine and xylometazoline may be used as decongestants prior to nasotracheal intubation to prevent this. We hypothesized that xylometazoline would prevent epistaxis more effectively than cocaine, demonstrated by a lower proportion of patients with bleeding after nasotracheal intubation. ⋯ We found no statistically significant difference between cocaine and xylometazoline in preventing epistaxis after nasotracheal intubation, and the choice of vasoconstrictor should be based on other considerations, such as pricing, availability and medicolegal issues.

Randomized Controlled TrialPerioperative association between c-reactive protein, pain catastrophizing and acute pain after total knee arthroplasty: A secondary analysis of two randomised trials.
Total knee arthroplasty is associated with an inflammatory response and high levels of pain in a subset of patients. Pain catastrophizing has been associated with acute postoperative pain. The association between these variables has not been investigated in an optimised fast-track setup including preoperative glucocorticoids. The aim of this study was, first, to investigate the correlation between the increase in postoperative c-reactive protein (CRP) and acute postoperative pain after total knee arthroplasty, and second, to investigate the correlation between the increase in CRP and preoperative pain catastrophizing. ⋯ There was no association between the postoperative CRP response and postoperative acute pain or pain catastrophizing in patients undergoing total knee arthroplasty in a well-defined multimodal fast-track regime including preoperative glucocorticoids. These results suggest that acute pain after knee arthroplasty is not reflected by CRP when applying preoperative glucocorticoids.

Randomized Controlled TrialAssociations between enteral nutrition and outcomes in the SUP-ICU trial: Results of exploratory post hoc analyses.
Enteral nutrition may affect risks of gastrointestinal bleeding, pneumonia and mortality in critically ill patients and may also modify the effects of pharmacological stress ulcer prophylaxis. We undertook post hoc analyses of the stress ulcer prophylaxis in the intensive care unit trial to assess for any associations and interactions between enteral nutrition and pantoprazole. ⋯ Enteral nutrition was associated with an increased risk of pneumonia and a reduced risk of gastrointestinal bleeding. The interaction between pantoprazole and enteral nutrition suggesting an increased risk of mortality requires further study.
