- Brief Summary
This is a single centre, open-label, feasibility randomised controlled trial. The study aims to assess the feasibility of conducting an RCT to compare the PneuX ETT with standard care in hospitalised patients requiring mechanical ventilation. The patient population for this study are those who are experiencing critical illness requiring intubation and ventilatory support. Patients will be randomised in equal proportions into one of 2 arms: to be intubated using a Venner PneuX Endotracheal Tube (ETT) or using the standard tube. For this feasibility study, a total of 50 patients will be randomised into two groups (25 in each). All patients will be recruited at a single site (University Hospital of Wales, part of Cardiff \& Vale UHB). The study will investigate several feasibility measures including recruitment, delivery of the intervention (including device-related adverse events), acceptability and adherence to the intervention and sampling, use of Peptest to measure microaspiration events, rate of pepsin positive samples, rate of tracheobronchial colonisation, volume of sub-glottic aspirate, rate of VAP, length of ICU and hospital stay, demonstrate the validity of study documentation and provide preliminary data for 50 patients. The data will inform the pilot and main phase of the study.

Group Intervention Description PneuX endotracheal tube PneuX Endotracheal Tube Patients will be intubated using the PneuX endotracheal tube system Standard care Standard care (Taperguard, Covidien) Patients will be intubated using standard endotracheal tube (Taperguard, Covidien).
- Primary Outcome Measures
Name Time Method To assess if a recruitment rate of 50 patient annually is achievable and identify any barriers to recruitment Through study completion, an average of 1 year The recruitment rate will be assessed using the "screening and recruitment log" which will record the number of patients recruited each month and reasons for non-recruitment will be described
- Secondary Outcome Measures
Name Time Method Number of participants with a failed pepsin test Duration of study treatment (typically 4-7 days) Any issues such as failed sampling or failed testing will be recorded in case report form
Proportion of patients who require antibiotics 28 days The following will be assessed: antibiotic prescribed, indication for use, number of days administered
Rate of Ventilator Associated Pneumonia (VAP) 28 days Number of patients with VAP diagnosis. Clinical Pulmonary Infection Score (CPIS) used to predict VAP. CPIS \>6 will be used to define confirmation of VAP. Measured daily after 48 hours of intubation
Number of participants with a positive pepsin tracheal aspirate sample using Peptest Duration of study treatment (typically 4-7 days) The proportion of tracheal aspirate samples which are positive for the presence of pepsin using the Peptest test
Time spent on the ventilator Duration of study treatment (typically 4-7 days) Days spent with mechanical ventilation in ICU (from time/date of intubation to time/date of extubation or 28 days)
Number of days spent in ICU and hospital 28 days Length of stay in ICU and length of stay in hospital measured in days from ventilation
Rate of in-hospital mortality 28 days Number of patients who die in hospital up to 28 days after entry into ICU
Volume of sub-glottic aspirates Duration of study treatment (typically 4-7 days) The volume of the sub-glottic aspirates will be measured every 24 hours
To assess the feasibility of delivering the study intervention Duration of study treatment (typically 4-7 days) Any issues experienced when using the study device at any point during the study will be recorded in the CRF, including device-related complications.
Rate of tracheobronchial colonization Duration of study treatment (typically 4-7 days) Tracheobronchial colonization (no. colony forming units/ml) present in sputum samples will be measured by culture on days 3 and 7
Rate of compliance with measuring and documenting cuff pressure Duration of study treatment (typically 4-7 days) Documentation of cuff pressures in both arms of study. Cuff pressure in standard care will be measured every 12 hours. Assessment of intervention arm will have documentation that pressure has been maintained hourly either via the continual cuff pressure monitor or manually.
