Randomized Controlled Trial Comparative Study
Microbiological comparison of the disinfecting efficacy of small and large cotton swabs in nasotracheal intubation: a randomized trial.
Nasotracheal intubation (NTI) is necessary during surgeries requiring clear access to the surgical field and in patients with respiratory issues. This study investigates the pre-NTI nasal disinfection efficacy of different cotton swab sizes, hypothesizing that smaller swabs could minimize bleeding while maintaining disinfection efficacy. ⋯ Cotton swab thickness did not impact disinfection efficacy, but large swabs increased the risk of nasal bleeding. We recommend FCS for nasal disinfection prior to NTI in ASA 1-2 patients, as they reduce bleeding risk without compromising disinfection.

Transpulmonary pressure is the effective pressure across the lung parenchyma and has been proposed as a guide for mechanical ventilation. The pleural pressure is challenging to directly measure in clinical setting and esophageal manometry using esophageal balloon catheters was suggested for estimation. However, the accuracy of using esophageal pressure to estimate pleural pressure is debated due to variability in the mechanical properties of respiratory system, esophagus and esophageal catheter. Furthermore, while a vertical pleural pressure gradient exists across lung regions, esophageal pressure balloon provides a single value, representing, at most, the pressure surrounding the esophagus. ⋯ The correction technique, based on the mechanical response of esophageal wall to the balloon inflation, is fundamental for obtaining reliable estimations of absolute intrathoracic pressure values, and for ensuring its correct application in clinical setting.

Observational Study
Changes of endotracheal tube cuff pressure and its indicators in laparoscopic resection of colorectal neoplasms: an observational prospective clinical trial.
Laparoscopic surgery is a popular alternative for resection of colorectal neoplasms. Carbon dioxide pneumoperitoneum and Trendelenburg positioning in procedure can significantly increase airway pressure, when endotracheal tube cuff pressure is not monitored. This prospective observational study aimed to evaluate indicators, changes and its correlation factors of endotracheal tube cuff pressure during laparoscopic resection of colorectal neoplasms. ⋯ Patients with normal BMI undergoing laparoscopic resection of colorectal neoplasms require continuous monitoring and timely adjustments of tracheal tube cuff pressure. Compared with BMI, waist-to-hip ratio is a better predictor of out-of-range tracheal tube cuff pressure.

Randomized Controlled Trial Comparative Study
The efficacy and safety of ciprofol versus propofol in patients undergoing painless hysteroscopy: a randomized, double-blind, controlled trial.
Studies have reported that ciprofol has the advantage of reducing injection pain compared to propofol during gastroscopy, colonoscopy, and fiberoptic bronchoscopy. The effect of ciprofol on the injection pain in painless hysteroscopy needs to further explore. ⋯ NCT06413862.

Randomized Controlled Trial Comparative Study
Ciprofol versus propofol for anesthesia induction in cardiac surgery: a randomized double-blind controlled clinical trial.
Ciprofol, a novel intravenous general anesthetic with a chemical structure similar to propofol, exhibits significantly enhanced potency. It offers a rapid onset, reduced incidence of injection pain, and has comparable effects on heart rate and blood pressure to propofol. However, clinical data on its use for anesthesia induction in cardiac surgery remain limited. ⋯ Ciprofol demonstrated a significantly lower incidence of injection pain compared to propofol, potentially improving patient comfort during anesthesia induction. Additionally, ciprofol showed comparable circulatory stability to propofol during anesthesia induction in cardiac surgery, suggesting it may be a suitable alternative to propofol for this application.
