Summary: This study developed a new coating method for endotracheal tubes, which can achieve both antibacterial and antifouling effects. The experiments demonstrated the inhibitory effect of the coating on various bacteria and its ability to prevent biofilm formation. The results also showed good stain resistance and biocompatibility of the coating.

Summary: Ventilator-associated pneumonia (VAP) is a persistent problem in hospitals, resulting in inadequate treatment, high mortality, and prolonged hospital stays. The endotracheal tube (ETT) is the main cause of VAP due to microbial colonization and biofilm formation by various pathogens. Research on antimicrobial ETT surface coating/modification approaches has been conducted to address this issue. This review provides an overview of the relevance of the ETT biofilms in VAP and the technological advancements in antimicrobial ETT materials. Rating: 8/10

Summary: This study compared the effect of closed versus open endotracheal tube suction on the occurrence of ventilator-associated pneumonia in mechanically ventilated neonates. The results showed that the choice of suction method did not significantly impact the incidence of ventilator-associated pneumonia in a unit with a low incidence of this condition.

Summary: The study evaluated the diagnostic value of ETT-aspirate sTREM-1 and serum C-reactive protein concentrations in neonatal ventilator-associated pneumonia (NVAP) among preterm and full-term neonates on mechanical ventilators. The results showed that these indicators may be useful for diagnosing NVAP, especially when combined. Changes in these indicators over ventilation days were also observed, providing valuable insights into neonatal recovery processes.

Summary: This study developed a biofilm-resistant coated endotracheal tube (ETT) that effectively reduced bacterial adhesion on the surface of the ETT. The coating had no impact on the viability of lung epithelial cells and exhibited a strong signal in computed tomography while having low cytotoxicity.

Summary: This study demonstrated that endotracheal tubes coated with the ceragenin CSA-131 significantly reduced biofilm formation of clinical strains of Pseudomonas aeruginosa and Escherichia coli. However, the difference was not statistically significant for Staphylococcus aureus. Further clinical studies are needed to support these findings.

Summary: Ventilator-associated pneumonia (VAP) is a common and serious nosocomial infection in mechanically ventilated patients. Recent studies have shown that tracheal intubation plays a key role in the pathogenesis of VAP, primarily through rapid colonization of the tracheal intubation surface by microbiota. Antibiotics are ineffective against microbial airway colonization, thus antimicrobial coating materials offer new solutions.

Summary: This study investigated the microbiome of the endotracheal tube (ETT) and found that it mainly consists of Proteobacteria, Firmicutes, and Bacteroidetes. The composition of the microbiome was associated with the ICU where the patients were hospitalized, but not with the duration of intubation or the diagnosis of ventilator-associated pneumonia (VAP). These findings suggest that the ICU environment or medical practices may influence the colonization of microbial communities in patients requiring mechanical ventilation.

Summary: Biofilm growth is important in the development of ventilator-associated pneumonia in intensive care units. The study reveals two different morphological aspects of endotracheal tube-deposited biofilm, as well as higher acquired resistance compared to other colonization sites. These findings have significant clinical implications for antimicrobial treatment in critically ill patients.

Summary: Data analysis on cases tested with bilateral BAL samples and EA showed that there was no significant improvement in diagnostic efficiency for detecting common viral respiratory pathogens. Discrepant results were observed in a small percentage of cases, indicating comparable diagnostic quality between EA and BAL samples for detecting common viral respiratory infections.

Summary: We conducted a health economic evaluation alongside the PROSPECT trial to compare the cost-effectiveness of probiotics and usual care in mechanically ventilated intensive care unit patients. The results showed that probiotics were not cost-effective for VAP prevention among critically ill patients.

Summary: This study compared the effect of regulating endotracheal tube cuff pressure using a smart cuff manager versus manual measurement approach on the incidence of VAP in mechanically ventilated patients. It was found that continuous maintenance of ETC pressure using SCM reduced the incidence of VAP, showing better effectiveness compared to manual measurement approach.

Summary: Ventilator-associated pneumonia is a common hospital infection that has a high mortality rate and prolonged hospitalization time. The endotracheal tube is a major cause of this pneumonia due to its surface being colonized by different pathogens. This paper discusses the definition, economic burdens, and outcomes of ventilator-associated pneumonia, as well as the latest technological solutions for endotracheal tube surfaces. The analysis concludes by identifying research gaps and exploring future possibilities for reducing ventilator-associated pneumonia cases and improving patient comfort.
