Ventilator-associated pneumonia (VAP) is a type of lung infection that occurs in people who are on mechanical ventilation breathing machines in hospitals. As such, VAP typically affects critically ill persons that are in an intensive care unit (ICU). VAP is a major source of increased illness and death. Persons with VAP have increased lengths of ICU hospitalization and have up to a 20–30% death rate. The diagnosis of VAP varies among hospitals and providers but usually requires a new infiltrate on chest x-ray plus two or more other factors. These factors include temperatures of >38 °C or <36 °C, a white blood cell count of >12 × 10⁹/ml, purulent secretions from the airways in the lung, and/or reduction in gas exchange.
Antibacterial and anti-adhesion double-balloon tracheal tube and preparation method thereof
This invention provides an antibacterial and anti-adhesion double-balloon tracheostomy cannula and its preparation method. The invention involves constructing a coating material co-loaded with a newly developed tetradecyl antibacterial agent and chondroitin sulfate on both the cannula's surface and inner wall. This coating possesses both excellent hydrophilicity and strong antibacterial properties. The hydrophilicity makes it difficult for secretions to adhere; the antibacterial properties kill bacteria through contact, minimizing the development of drug resistance; and the anti-adhesion properties reduce the basis for biofilm formation. These three properties work synergistically to achieve full-chain protection from the "source" to the "process," significantly reducing the risk of luminal obstruction and VAP (ventilator-associated pneumonia), while also reducing the frequency of suctioning and mucosal damage, thus improving patient comfort.
