Review[Talking to Unconscious? - Therapeutic Communication During General Anaesthesia, Resuscitation and Therapy of Coma].
There are numerous reports from patients concerning perceptions during deep unconsciousness, be it general anaesthesia, cardiopulmonary resuscitation or intensive care and coma treatment. These experiences can cause considerable traumatisation. The most stressful experience is apparently not feeling pain, but the lack of communication, i.e. being recognised and being able to express oneself. Although there are already indications of positive effects of positive communication during general anaesthesia, these findings have not yet markedly changed the way we deal with the unconscious.

Continuity with caveats in anesthesia: state and response entropy of the EEG.
The growing use of neuromonitoring in general anesthesia provides detailed insights into the effects of anesthetics on the brain. Our study focuses on the processed EEG indices State Entropy (SE), Response Entropy (RE), and Burst Suppression Ratio (BSR) of the GE EntropyTM Module, which serve as surrogate measures for estimating the level of anesthesia. While retrospectively analyzing SE and RE index values from patient records, we encountered a technical anomaly with a conspicuous distribution of index values. ⋯ This phenomenon occurs independently of the BSR distribution. SE and RE index values do not adhere to a continuous distribution, instead displaying prominent pillar indices with a consistent pattern of occurrence across all age groups. The specific features of the underlying algorithm responsible for this pattern remain elusive.

Meta Analysis Comparative Study
Remimazolam vs. propofol for general anaesthesia in elderly patients: a meta-analysis with trial sequential analysis.
Elderly patients comprise an increasing proportion of patients undergoing surgery, and they require special attention due to age-related physiological changes. Propofol is the traditional agent for anaesthesia, and recently, remimazolam, a novel ultra-short-acting benzodiazepine, has emerged as an alternative to propofol in general anaesthesia. ⋯ Remimazolam significantly reduced the risk of hypotension, bradycardia and injection pain, despite an increase in the time to loss of consciousness. Remimazolam appears to be an effective and well tolerated alternative to propofol in elderly patients undergoing general anaesthesia.

Randomized Controlled TrialEfficacy of Single-Bolus Administration of Remimazolam During Induction of Anesthesia in Patients Undergoing Cardiac Surgery: A Prospective, Single-Center, Randomized Controlled Study.
Remimazolam is a recently marketed ultrashort-acting benzodiazepine. This drug is considered safe and effective during general anesthesia; however, limited information is available about its effects on patients undergoing cardiac surgery. Therefore, the present study was conducted to evaluate the efficacy and hemodynamic stability of a bolus administration of remimazolam during anesthesia induction in patients undergoing cardiac surgery. ⋯ A single-bolus injection of remimazolam provided efficient anesthetic induction in patients undergoing cardiac surgery. A 0.2 mg/kg bolus injection of remimazolam resulted in the shortest time to loss of responsiveness among the 3 groups, without significantly altering the hemodynamic parameters. Therefore, this dosing can be considered a favorable anesthetic induction method for patients undergoing cardiac surgery.
