Filter by:The hyperinflation ventilator was performed in different modalities and ventilatory adjustments, with total pressure of 40cmH2O. The inspiratory volume, inspiratory time, mean airway pressure, inspiratory and expiratory flow, and bias flow were evaluated.
The study has been conducted to measure the clinical outcome of early intervention with colistin inhalation in patients with ventilator associated pneumonia suspected to have multidrug resistant gram -ve bacteria
Background: Optimising the use of antibiotic agents is a pressing challenge to overcoming the rapid emergence and spread of multidrug-resistant pathogens in intensive care units (ICUs). Although Gram staining may possibly provide immediate information for predicting pathogenic bacteria, Gram stain-guided initial antibiotic treatment is not well established in the ICU setting. The investigators planned the GRam stain-guided Antibiotics ChoicE for Ventilator-Associated Pneumonia (GRACE-VAP) trial to investigate whether Gram staining can safely restrict the use of broad-spectrum antibiotics in patients with ventilator-associated pneumonia (VAP), which is one of the most common hospital-acquired infections in ICUs. Methods/Design: The GRACE-VAP trial is a multicenter, randomised, open-label parallel-group trial to assess the non-inferiority of Gram stain-guided initial antibiotic treatment to guidelines-based initial antibiotic treatment for the primary endpoint of clinical cure rate in patients with VAP. Secondary endpoints include the coverage rates of initial antibiotic therapies, the selected rates of anti-pseudomonal agents and anti-methicillin-resistant Staphylococcus aureus (MRSA) agents as initial antibiotic therapies, 28-day all-cause mortality, ICU-free days, ventilator-free days, and adverse events. Participants are randomly assigned to receive Gram stain-guided treatment or guidelines-based treatment at a ratio of 1:1. In the Gram stain group, results of Gram staining of endotracheal aspirate are used to guide the selection of antibiotics. In the guidelines group, the combination of an anti-pseudomonal agent and anti-MRSA agent are administered. A total sample size of 200 was estimated to provide a power of 80% with a 1-sided alpha level of 2.5% and a non-inferiority margin of 20%, considering 10% non-evaluable participants. Discussion: The GRACE-VAP trial is expected reveal whether Gram staining can reduce the use of broad-spectrum antibiotics without impairing patient outcomes and thereby provide evidence for an antibiotics selection strategy in patients with VAP.
Ventilator-associated events (VAE) are a scourge of critical care settings and hospital systems at large. There is extensive evidence that ventilator-associated pneumonia (VAP) and related VAEs increase mortality rates in critically ill patients by up to 50%, while simultaneously increasing cost of care. C Best-practice guidelines state that positioning ventilated patients at an angle between 30-45 degrees significantly reduces the potential for VAP and other VAE to develop. While the intent of the guidelines is to govern patient elevation angle, the lack of a mechanism to accurately measure patient elevation requires that nurses rely on the head-of-bed (HOB) protractor - a tool which reflects the angle of the bed, not the patient - to measure compliance. Depending upon the position and posture of the patient in the bed, a patient's elevation angle may be significantly different from the HOB angle. Critical care teams currently rely on built-in HOB protractors and digital inclinometers that measure the angle of the bed not the patient. Angulus, LLC has developed a dual-component Angulus sensor to fill this gap in critical care technology. Angulus enables critical care practitioners to instantaneously understand a patient's elevation, identify when the patient is outside of the desired 30-45 degree recumbency scope, and efficiently correct the patient's orientation with immediate feedback. Angulus supports real-time minute-to-minute data display as well as longitudinal aggregation of data.
Intensive care units (ICUs), with high antibiotic consumption, are epicentres of antimicrobial resistance (AMR). Ventilator associated pneumonia (VAP) is the commonest hospital-acquired infection (HAI) in ICUs and is associated with a high morbidity and mortality in these vulnerable patients despite antibiotic therapy. No well-designed clinical trials studying antibiotic duration for VAP caused by predominantly non-fermenting Gram-negative bacteria have been conducted to date. Shortening antibiotic duration has the potential to improve individual patient outcomes and indirectly benefit other patients by reducing the selection pressure for multidrug resistant (MDR) bacteria within the ICU. The study aims to demonstrate clinical non-inferiority-superiority of a short duration of antibiotics (up to 7 days) versus prolonged antibiotic therapy (as per physician preference) in adults with VAP in Asia. Patients who have been ventilated for more than 48 hours will be screened daily for signs and symptoms of VAP according to the US Centers for Disease Control and Prevention VAP criteria. Recruited patients will be reviewed daily for clinical signs of stability including temperature <38°C for 48 hours, systolic blood pressure >90mmHg without inotropes. Recruited patients will be randomised once they fulfill these clinical criteria of stability. In the intervention arm, antibiotics should be stopped within 7 days once the above criteria are fulfilled. In the control arm, antibiotics should be at least 7 days with the exact duration decided by the managing physicians. The primary outcome of the study is a combined endpoint of mortality and VAP recurrence at day 60 of recruitment. The study hypothesis is that a shorter duration of treatment for VAP (7 days or less depending on clinical response) is not only noninferior, but may also be superior to a longer duration (8 days or more). The secondary outcomes of the study include clinical parameters such as rate of acquisition of MDRO hospital-acquired infections, duration of ventilation and hospitalization and days of antibiotics use. The study team will also characterise the microbiome changes in study participants according to the type and duration of antibiotics. MDROs collected will undergo whole genome sequencing for transmission dynamics study. The study is a multinational multicenter study involving hospitals in Asia. Funder: The project will beis partly joinly funded by Medical Research Council/ Department for International Development (MRC/DfID) and Singapore National Medical Research Council (NMRC/CTG). Grant Ref: MR/K006924/1 and MOH-000470 (MOH-CTGIIT18may-0003) Conclusions This is a randomised controlled hierarchical non-inferiority-superiority trial being conducted in ICUs across Nepal, Thailand and Singapore. The primary outcome is a composite endpoint of death and pneumonia recurrence at day 60. Secondary outcomes include ventilator-associated events, multidrug-resistant organism infection or colonisation, total duration of antibiotic exposure, mechanical ventilation and hospitalisation. Adult patients who satisfy the US Centers for Disease Control and Prevention National Healthcare Safety Network VAP diagnostic criteria are enrolled. Participants are assessed daily until fever subsides for >48 hours and have stable blood pressure, then randomised to a short duration treatment strategy or a standard-of-care duration arm. Antibiotics may be stopped as early as day 3 if respiratory cultures are negative, and day 5 if respiratory cultures are positive in the short-course arm. Participants receiving standard-of-care will receive antibiotics for at least 8 days. Study participants are followed for 60 days after enrolment. An estimated 460 patients will be required to achieve 80% power to determine non-inferiority with a margin of 12%. All outcomes are compared by absolute risk differences. The conclusion of non-inferiority, and subsequently superiority, will be based on unadjusted and adjusted analyses in both the intention-to-treat and per-protocol populations.

hospital-acquired pneumonia are a common disease in intensive care unit. The prevention, the diagnosis and the treatment of hospital acquired pneumonia are a frequent challenge. Nevertheless it seems that there are great differences in standard of care between hospitals. The investigators hypothesized that medical education and implementation of evidence-base guidelines can reduce the duration of mechanical ventilation in patients presenting of hospital acquired pneumonia
A Phase 3 comparative study to determine the efficacy, safety and tolerability of Aztreonam-Avibactam (ATM-AVI) ± Metronidazole (MTZ) versus Meropenem (MER) ± Colistin (COL) for the treatment of serious infections due to Gram negative bacteria.
Prospective, multicenter observational study to collect Escherichia coli (E. coli) isolates originating from mechanically ventilated intensive care unit (ICU) patients; in order to characterize phenotype and genotype of E. coli strains retrieved from the lower respiratory tract of ventilated patients.
Ventilator Associated Pneumonia (VAP) is associated with increased hospitalisation, increased health care cost and high morbidity and mortality. The incidence of VAP increases with duration of mechanical ventilation. There is limited data especially from India on the incidence of VAP and also the role of subglottic aspiration in its prevention. The aim of this study is to determine the role of subglottic suction in the incidence of VAP.
Ventilator-associated pneumonia (VAP), is a type of pneumonia that develops more than 48 hours after endotracheal intubation, is common in intensive care units (ICUs). It is estimated to be responsible for 27% to 47% of ICU-acquired infections. The pathogenesis of VAP is complex but typically involves colonization of the aerodigestive tract with pathogenic bacteria, the formation of biofilms, and microaspiration of contaminated secretions. Preventing carriage of potentially pathogenic micro-organisms from the aerodigestive tract is an infection control strategy used to reduce the occurrence of VAP. One novel intervention is the administration of prophylactic probiotics which restore non-pathogenic flora that compete with pathogens, modulate local and systemic immunity, and decrease intestinal permeability and thus can be beneficial in preventing nosocomial infections in critically ill patients. The role of the probiotics in preventing VAP in mechanically ventilated patients is inconclusive. Some evidence indicates that probiotics may reduce the incidence of VAP by inhibiting pathogen adhesion, improving gut mucosal barrier function, reducing bacterial translocation and up-regulating the immune system. Furthermore, guidelines remain inconclusive regarding the role of commensal oropharyngeal flora (COF) as a causative agent in VAP, mainly due to a scarcity of studies in this research field. However, there is evidence that COF may cause pulmonary infection, mostly in immunocompromised patients.
