To enhance the utility of functional hemodynamic monitoring, the variables systolic slope (dP/dt) and dynamic arterial elastance (Eadyn) are calculated by the Hypotension Prediction Index (HPI) Acumen® Software. This study was designed to characterize the effects of phenylephrine and ephedrine on dP/dt and Eadyn. ⋯ Bolus administration of phenylephrine or ephedrine increases dP/dt but does not change Eadyn. dP/dt demonstrates potential for predicting the inotropic response to phenylephrine or ephedrine, providing guidance for the most efficacious vasopressor when treating hypotension.

This meta-analysis aimed to investigate the effect of dexmedetomidine on brain-derived neurotrophic factor (BDNF) levels in individuals undergoing various medical procedures. We systematically searched electronic databases and manually identified relevant articles to assess the impact of dexmedetomidine on BDNF levels in surgical patients. ⋯ This meta-analysis indicates that dexmedetomidine administration is associated with a significant increase in BDNF levels in individuals undergoing surgical procedures. These findings highlight the potential role of dexmedetomidine in modulating BDNF levels, which may have implications for optimizing perioperative neuroprotective strategies and improving patient outcomes.

Checklists are a common tool used in order to mitigate risks caused by human factors and can facilitate the safe induction of anesthesia as well as handovers. SBAR (Situation, Background, Assessment, Recommendation) is a checklist recommended by the WHO and DGAI for handovers, while SOAP-M (Suction, Oxygen, Airway, Pharmaceuticals, Monitoring) is a checklist for the induction of anesthesia. This study investigates the implementation and adoption of these two checklists. ⋯ SOAP-M and SBAR are perceived as useful checklists for patient handovers and anesthesia induction by tertiary referral hospital's employees with high score in general safety attitude and were therefore commonly used one year after their introduction. No significant difference in checklist adoption between occupations as well as groups divided according to work experience could be found. Perceived usefulness is significantly higher among users of the checklist, who feel using the checklists provides more support.

Randomized Controlled Trial Comparative Study
Comparing the clinical features of lateral and medial approaches of costoclavicular technique versus traditional lateral sagittal technique as infraclavicular brachial plexus block methods: a randomized controlled trial.
It is aimed to compare the block onset times and performance features of costoclavicular techniques (medial and lateral approach) versus lateral sagittal technique. ⋯ Lateral approach costoclavicular technique provides fastest block onset than the other techniques. Considering the success and safety profile, this technique stands as a good alternative in clinical practice.

Randomized Controlled Trial
The effects of remimazolam combined with sufentanil on respiration, circulation and sedation level in patients undergoing colonoscopy.
The main sedative which is propofol in painless gastroenteroscopy, has a high risk of reducing blood pressure and respiratory depression. Remimazolam (a short-acting benzodiazepine) is expected to be widely used in painless gastroenteroscopy due to its rapid onset, rapid metabolism and light respiratory and circulation inhibition. ⋯ This study revealed that remimazolam is a safe and effective medication for colonoscopy sedation, the security of remimazolam is better than propofol, and the sedative effect with the initial dose of 0.25 mg/kg of remimazolam is optimal.
