The Bispectral Index (BIS) and the Patient State Index (PSI) are commonly used measures to assess intraoperative sedation depth. However, model differences lead to different results, which in turn interferes with clinicians' judgment on the depth of anesthesia. Remimazolam tosilate (RT) for injection is a new benzodiazepine used in sedation. In its clinical application, there are few effective indicators for sedation depth monitoring. To close this gap, this study aims to compare BIS and PSI in measuring the sensitivity and specificity of intraoperative RT and to explore the safety of RT for intraspinal anesthesia in elderly patients. ⋯ BIS and PSI are strongly associated for monitoring the sedation of RT intraoperatively. Both methods can accurately reflect sedation depth. According to correlation analyses with MOAA/S scale and ROC curves, BIS is more accurate than PSI during such intraoperative monitoring. In addition, RT can be safely used in elderly patients under intraspinal anesthesia for supportive sedation, with stable vital signs and sound kidney and liver safety profiles.

Postoperative airway morbidities in pediatric patients.
Pediatric airway management is a huge challenge for anaesthetists, and airway-related complications should be actively addressed and focused on.

Multicenter Study
Critical incidents during anesthesia: prospective audit.
Critical incident reporting and analysis is one of the key components of patient safety in anesthesiology. The aim of this study was to determine the frequency and characteristics of critical incidents during anesthesia, main causes and factors involved, influence on patient outcomes, prevalence of incident reporting and further analysis. ⋯ NCT05435287, clinicaltrials.gov, 23/6/2022.

Regional anesthesia appears to reduce cancer recurrence, but the optimal anesthesia modality for non-muscle invasive bladder cancer (NMIBC) were still under debate. Therefore, we sought to assess the effect of regional and GA only upon the recurrence and long-term prognosis of NMIBC through this meta-analysis. ⋯ RA, especially spinal anesthesia, may be effective in reducing the recurrence rate after transurethral resection of NMIBC. More prospective experimental and clinical studies are needed to validate our findings.

Patients who undergo gastrointestinal endoscopy often require propofol-based sedation combined with analgesics. At present, the efficacy and safety of esketamine as an adjunct to propofol for sedation during endoscopic procedures in patients remains controversial. Moreover, there is no universal agreement regarding the appropriate dose of esketamine supplementation. This study aimed to assess the efficacy and safety of esketamine as an adjunct to propofol for sedation during endoscopic procedures in patients. ⋯ Esketamine as an adjunct to propofol, is an appropriate effective alternative for sedation in participants undergoing gastrointestinal endoscopy. However, considering the possibility of its psychotomimetic effects, esketamine should be used with caution.
