Background: The ability of current depth-of-anaesthesia monitors to differentiate subtle changes in the conscious state has not been well characterised. We examine the variability in bispectral index (BIS) scores associated with disconnected conscious and unconscious states as confirmed by a novel serial awakening paradigm.
Methods: Seventy adult participants, given propofol or dexmedetomidine, had a cumulative 1381 electroencephalographic (EEG) recordings across two centres.
Article Synopsis
- The study aimed to evaluate the outcomes of two methods for treating acromioclavicular (AC) separations using a tendon graft and a titanium implant, focusing on potential coracoid fractures as a primary concern.
- Twenty-seven patients were divided into two groups based on their AC separation severity, and outcomes like wound healing, functional scores, and patient satisfaction were assessed preoperatively and 24 months later.
- Results showed significant improvements in shoulder function and no complications related to the procedure, indicating both methods were effective without significant differences between them.
Article Synopsis
- Inhaled xenon combined with hypothermia was tested on comatose patients who survived out-of-hospital cardiac arrest (OHCA) to see if it could protect gray matter in the brain.
- A study of 110 patients found that those who received inhaled xenon and temperature management showed less reduction in brain gray matter volume, especially in areas like the amygdala and temporal gyrus, compared to those who received only temperature management.
- The results suggest that inhaled xenon can help preserve brain structure in this patient group, highlighting its potential therapeutic benefits.
Article Synopsis
- This study investigates the effects of inhaled xenon on metabolic outcomes in out-of-hospital cardiac arrest survivors receiving targeted temperature management.
- Blood samples showed that increased lactate and decreased branched-chain amino acids (BCAAs) were associated with higher mortality rates at 24 and 72 hours post-arrest.
- The findings suggest that high levels of lactate and alanine, along with low BCAAs and small HDL cholesterol, are linked to negative outcomes, while inhaled xenon did not significantly impact the metabolic profile of patients.
Background: This exploratory study aimed to investigate whether dexmedetomidine, propofol, sevoflurane, and S-ketamine affect oxylipins and bile acids, which are functionally diverse molecules with possible connections to cellular bioenergetics, immune modulation, and organ protection.
Methods: In this randomised, open-label, controlled, parallel group, Phase IV clinical drug trial, healthy male subjects (=160) received equipotent doses (EC for verbal command) of dexmedetomidine (1.5 ng ml; =40), propofol (1.
