Active clinical trials for "Pneumonia, Ventilator-Associated"

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.

A randomized controlled triple blinded clinical trial with repeated measurements. The reporting of this study complies with the CONSORT (Consolidated Standards of Reporting Trials) statement for trials of non-pharmacological treatments. The first aim of the study was to evaluate the effectiveness of the three competing interventions on the critical care nurses' knowledge of, attitudes toward and adherence to 17 ventilator bundle components; the second aim was to determine the effectiveness of adherence to 17 ventilator bundle components with pre-defined ventilator bundle on the psychological factors of critical care nurses including nurses' stressors in intensive care unit (ICU), perceived stress, trait and state anxieties; the third aim was to evaluate their impact on the clinical outcomes; and the fourth aim was comparing KAP and psychological factors with clinical outcomes.

Dental plaque score calculation and swabs of Oropharynx and teeth were collected on admission. For group I, Miswak stick was used 4 hourly for oral care. For group II, 0.12% Chlorhexidine/ toothbrush were used 4 hourly

The purpose of this study is to test the efficacy of a novel cleaning device in keeping silver-coated endotracheal tubes free from bacterial colonization.

Ventilator-associated pneumonia (VAP) is a serious complication and carries increased risks of morbidity and mortality for patients who require mechanical ventilation. VAP is associated with the contamination and colonization of bacteria in the lower airway. These bacteria may be present in the lower airway by the aspiration of oropharyngeal secretions. Therefore limiting the amount of secretions that pass the glottis and enter the airway is paramount. Patients who require prolonged mechanical ventilation may have a tracheostomy tube placed to manage breathing. These tubes may have a distal cuff which sits within the trachea. When the cuff is inflated, oropharyngeal secretions will pool above the cuff of the tracheostomy tube thereby limiting the amount of secretions entering the lower airway. These secretions may leak around the cuff and cause tracheobronchial colonization. It has been shown that removal of secretions that pool above the cuff via dorsal lumen suction leads to a decreased incidence of VAP. The purpose of this study is to measure the effect of suction above the cuff tracheostomy tubes related to VAP incidence

Background and rationale: Antimicrobial resistance is a global public health threat. An increasing number of Gram-negative bacteria isolates worldwide are resistant to virtually all antibiotics including carbapenems. Although polymyxins are the current gold standard antibiotic for treatment of severe extensively drug-resistant Gram-negative bacteria (XDR-GNB - defined in Appendix I) infections, resistance development on therapy and treatment failures are common. Combination antibiotics therapy have better in vitro efficacy, but have not been formally tested in a prospective trial. We will conduct a Phase IIB, prospective, open-label, randomized-controlled trial in 4 major Singaporean hospitals, with balanced treatment assignments achieved by permuted block randomization, stratified by hospital. There will be 75 subjects per arm, with the subjects in the comparator arm receiving standard-dose polymyxin B while the intervention arm will receive a second antibiotic, doripenem, with polymyxin B against the bacterial isolate in question. Subjects with ventilator-associated pneumonia (VAP) will additionally receive nebulized colistin. The primary outcome is 30-day mortality while secondary outcomes include microbiological clearance, time to defervescence, and toxicity of therapy, presence of secondary infections due to new multi-drug resistant bacteria and length of ICU stay. Plasma drug levels will be measured by liquid chromatography-mass spectrometry. Hypothesis: The underlying primary hypothesis is that combination antibiotic therapy (IV polymyxin B + IV doripenem) is superior to mono-antibiotics therapy (IV polymyxin B) in reducing 30-day mortality from XDR-GNB infections.

The purpose of this study is to determine if oral mucosal application of chlorhexidine gel will prevent the development of ventilator associated pneumonia in children.

Several studies have shown that PCT guidance can reduce the duration of antibiotic treatment for patients with bacterial infections in the ICU, without compromising the safety outcomes. However PCT is known to be more costly than standard biomarkers that commonly use in our ICU setup. This remain the main challenge for us whether by monitoring the PCT level, it can reduce both the duration of antibiotic simultaneously reduce the total cost of the treatment for the patients. A local study addressing efficacy, safety and cost analysis of PCT-guided antibiotic therapy in severe pneumonia patients is therefore warranted. Until the results from a local study become available, the utility of PCT to guide antibiotic duration in our patient population cannot be recommended.

asses diagnostic performance of different methods for detection of ventilator associated pneumonia.

The objective of the study is to prove that after the third day of invasive mechanical ventilation a three-day course of inhaled amikacin reduces the incidence of subsequent VAP. Parallel two group double blind randomized controlled clinical trial. Individual randomization, performed on day 4 of invasive mechanical ventilation, will be stratified on centre in order to account for variations in VAP prevention bundle implementation and use of systemic antibiotics the day of randomization. Patients will be treated three consecutive days with inhaled amikacin or placebo. Patients will be followed up daily in the intensive care unit for the occurrence of VAP according to international guidelines until day 28.
