Randomized Controlled TrialHigh Dose Preoperative Glucocorticoid for Prevention of Emergence and Postoperative Delirium in Liver Resection: A Double-Blinded Randomised Clinical Trial Substudy.
Emergence delirium (ED) and postoperative delirium (POD) are associated with increased morbidity and mortality and occur in up to one-third of patients undergoing major non-cardiac surgery, where the underlying pathogenesis is multifactorial, including increased inflammation. We aimed to assess the effect of pre-operative high- versus low-dose glucocorticoid on the occurrence of ED and POD. ⋯ The primary finding of the current substudy was a lower occurrence of ED/POD in the PACU 90 min after arrival and during the first four postoperative days in patients receiving high-dose glucocorticoid compared with patients receiving low-dose glucocorticoid. The two study groups were not evenly balanced concerning known explanatory factors, i.e., age and size of surgery, which calls for larger studies to elucidate the matter.

Randomized Controlled TrialAuraGain™ versus i-gel™ for Bronchoscopic Intubation under Continuous Oxygenation: a Randomised Controlled Trial.
After failed mask ventilation and tracheal intubation, guidelines issued by the Difficult Airway Society recommend placing a second generation supraglottic airway device to secure oxygenation. Ultimately, a secure airway can be obtained by tracheal intubation through the supraglottic airway device using a bronchoscope. In this randomised trial, we compared the AuraGain™ with the i-gel™ as conduit for bronchoscopic intubation under continuous oxygenation performed by a group of anaesthesiologists with variable experience in a general population of patients. ⋯ We found no difference in total time for airway management between using the i-gel™ and using the AuraGain™.

Randomized Controlled TrialSerum biomarkers of brain injury after uncomplicated cardiac surgery: Secondary analysis from a randomized trial.
Postoperative cognitive dysfunction is common after cardiac surgery. Postoperative measurements of brain injury biomarkers may identify brain damage and predict cognitive dysfunction. We describe the release patterns of five brain injury markers in serum and plasma after uncomplicated cardiac surgery. ⋯ Uncomplicated cardiac surgery with cardiopulmonary bypass is associated with an increase in serum/plasma levels of all the studied injury markers, without signs of blood-brain barrier injury. The biomarkers differ markedly in their levels of release and time course. Further investigations are required to study associations between perioperative release of biomarkers, postoperative cognitive function and clinical outcome.

Randomized Controlled TrialUltrasound-guided multiple injection costotransverse block for mastectomy and primary reconstructive surgery. A study protocol.
Post-operative pain amelioration following breast cancer surgery is inconsistent. The novel multiple-injection costotransverse block (MICB) mimics the thoracic paravertebral block by possible anaesthetising the ventral rami of the thoracic spinal nerves and the sympathetic trunk. Proof of concept has been determined in a cadaveric study and needs further clinical testing. ⋯ Recruitment began in November 2019 and is expected to finish ultimo 2021. Results are expected to be published in an international peer-reviewed medical journal. The results will hopefully provide a substantial contribution to the knowledge of these new 'intertransverse process blocks' providing regional anaesthesia of the thoracic wall.

Randomized Controlled TrialHigher versus lower oxygenation targets in COVID-19 patients with severe hypoxaemia (HOT-COVID) trial: Protocol for a secondary Bayesian analysis.
Respiratory failure is the main cause of mortality and morbidity among ICU patients with coronavirus disease 2019 (COVID-19). In these patients, supplemental oxygen therapy is essential, but there is limited evidence the optimal target. To address this, the ongoing handling oxygenation targets in COVID-19 (HOT-COVID) trial was initiated to investigate the effect of a lower oxygenation target (partial pressure of arterial oxygen (PaO2 ) of 8 kPa) versus a higher oxygenation target (PaO2 of 12 kPa) in the ICU on clinical outcome in patients with COVID-19 and hypoxaemia. ⋯ The results of this pre-planned secondary Bayesian analysis will complement the primary frequentist analysis of the HOT-COVID trial and may facilitate a more nuanced interpretation of the trial results.
