Filter by:Biofilm is a microstructure organised into aggregates of microbiological species within a polymeric matrix. As early as the 2000s, the Centers for Disease Control and Prevention (CDC) recognised the possible role of the biofilm lining endotracheal endotracheal tubes in the development of ventilator-associated pneumonia (VAP) , the most common infection in intensive care, with a high morbidity and mortality rate and a significant increase in hospital costs. Targeting biofilm therefore now appears to be a new area of interest for limiting the risk of VAP, and this rationale has led to the development of an intraluminal for abrading biofilm deposited on the inside of the intubation probe . Evaluation of this type of strategy nevertheless justifies the introduction of more precise methods for characterisation of the biofilm. To this end, the investigator carried out an initial clinical study describing the biofilm on intubation probes, BIOPAVIR 1, showing the existence of several biofilm structures, each associated with a specific microbiological signature. Several limitations including a lack of power due to an insufficient number of patients and the use of number of patients, and the use of a confocal microscopy technique with poor axial without the possibility of acquiring metabolic images of the biofilm. Based on the previous description of biofilm by optical coherence tomography (OCT), and a recent experience with an optimised form of high-resolution OCT, called full-field OCT, the investigator hypothesise that full-field OCT will allow more accurate characterisation of biofilm, due to its high spatial resolution and its potential ability to capture metabolic activity in the biofilm BIOPAVIR 2 proposes to use the performance of full-field OCT to better characterise the biofilm lining endotracheal tubes in patients undergoing mechanical ventilation in intensive care units. This project represents a first step towards understanding the link between the development of biofilm on intubation and the occurrence of VAP
Artificial airways, such as endotracheal tubes and tracheostomies, in the pediatric and neonatal intensive care units (PICU, NICU respectively) are lifesaving for patients in respiratory failure, among other conditions. These devices are not without a risk of infection - ventilator-associated infections (VAIs), namely ventilator associated pneumonia (VAP) and ventilator-associated tracheitis (VAT), are common. Treatment of suspected VAI accounts for nearly half of all Pediatric Intensive Care Unit (PICU) antibiotic use. VAI can represent a continuum from tracheal colonization, progression to tracheobronchial inflammation, and then pneumonia. Colonization of these airways is common and bacterial growth does not necessarily indicate a clinically significant infection. Tracheostomies, which are artificial airways meant for chronic use, are routinely exchanged on a semi-monthly to monthly basis, in part to disrupt bacterial biofilm formation that aids bacterial colonization and perhaps infection. When patients with tracheostomies are admitted for acute on chronic respiratory failure or a concern for an infection, these artificial airways are also routinely exchanged at some institutions. There however remains a critical need to understand how an artificial airway exchange alters the bacterial environment of these patients in sickness and in health. This research hypothesizes that exchanging an artificial airway will alter the microbiome of the artificial airway, by altering the microbial diversity and relative abundance of different bacterial species of the artificial airway. This study will involve the prospective collection of tracheal aspirates from patients with artificial airways. We will screen and enroll all patients admitted to a the NICU or PICU at Cohen Children's Medical Center (CCMC) who have tracheostomies and obtain tracheal aspirates within 72 hours before and after tracheostomy or endotracheal tube exchange. Tracheal aspirates are routinely obtained in the NICU and PICU from suctioning of an artificial airway and is a minimal risk activity. These samples will be brought to the Feinstein Institutes for Medical Research for 16 s ribosomal DNA (16srDNA) sequencing, which allows for accurate and sensitive detection of relative abundance and classification of bacterial flora. Tracheal aspirate sets will be analyzed against each other. Additionally, clinical and epidemiological data from the electronic medical record will be obtained. Antibiotic exposure will be accounted for via previously published means.
The researchers are studying whether special features make it easier to see if the breathing tube is in the correct place. It is hoped that the investigational device will enable more accurate placement (depth and trachea vs. esophagus).
The aim of this prospective, randomized study is to compare the performance, safety, and ease of use (usability) between two closed suction systems, the AirWay Medix Closed Suction System and Kimberly KimVent while intubated with an endotracheal in hospitals and ICU. 26 adults with an endotracheal tube and mechanical ventilation will be randomized into 2 groups to receive one of the following closed suction systems endotracheal tubes: 1. AirWay Medix Closed Suction System 2. KimVent Turbo-Cleaning Closed Suction System Kimberly clarK The groups will be compared regarding the safety, performance and ease of use (usability).
