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.

Patients undergoing Extracorporeal Membrane Oxygenation (ECMO) are particularly susceptible to infections: 42% experience sepsis and 26% develop a nosocomial infection (NI). Whether antibiotic prophylaxis is effective in reducing mortality and its effects on the rate of NIs is currently unclear. ⋯ PROSPERO: International prospective register of systematic reviews, 2024, CRD42024567037.

Comparative Study
Effects of GlideScope, Pentax Airway Scope, and Macintosh Blade on the incidence of postoperative sore throat: a cohort study of 9,881 patients.
Postoperative sore throat (POST) is a common complaint after general anesthesia. POST is defined by the presence of a self-reported foreign body sensation or a painful sensation in the throat after general anesthesia. This condition may affect recovery and patient satisfaction and is associated with many factors, including intubation tools. Previous studies have reported conflicting results on POST. This retrospective cohort study, with sample size of 9,881 patients, was conducted to confirm the hypothesis that the use of video laryngoscopy (VL) is associated with a lower incidence of POST compared with direct laryngoscopy (DL). ⋯ Compared with DL, VL is associated with a lower incidence of POST. In addition, the use of AWS is associated with a lower incidence of POST compared with the use of GVL.
