Filter by:The objective is to assess the efficacy and safety of oral simvastatin in patients with a suspicion of ventilator-associated pneumonia (VAP). The hypothesis of this study is that simvastatin therapy will improve mortality in patients a suspicion of VAP.
- Background: Ventilator-acquired pneumonia (VAP) is the most prevalent nosocomial infection in intensive care units (ICUs). Early microbiological diagnosis and initial administration of appropriate antimicrobial therapy are associated with a better outcome. Broad-spectrum antibiotics should therefore be administered initially. However, inconsiderate antibiotic use can increase the prevalence of multi-resistant bacteria. - Purpose: A rapid antimicrobial susceptibility method is required to decrease the unnecessary use of empirical broad-spectrum antibiotics. The aim of this study is to compare the efficiency of a rapid antibiogram, provided by E-test strips directly applied to bronchoalveolar lavage (BAL) samples and analysed at 24 h, to that obtained with standard methods of culture which provide a later result. - Study design: This will be an open-label, prospective cohort study of consecutive patients with VAP, conducted in a medical ICU. In addition to standard culture methods, an E-test will be performed directly on BAL samples and analysed at 24 h. Each standard BAL culture will be used as a control for the E-test method. - Primary outcome: The occurrence of major errors, defined as isolates determined to be susceptible by the E-test but resistant by standard culture methods. - Secondary outcomes: The occurrence of minor errors (defined as isolates determined to be resistant by the E-test and susceptible by the standard method), and a comparison of two methods of seeding BAL samples on Mueller Hinton agar plates (swabbing method, flooding method). - Eligibility criteria: - Inclusion criteria: all patients with suspected VAP (defined by a Clinical Pulmonary Infection Score ≥5) undergoing BAL will be eligible. - Exclusion criteria: contraindications for BAL (PaO2/FIO2 <100, risk of bronchoscopy-related haemorrhagic complications), secondary exclusion of patients with negative cultures, defined by a threshold of bacteria <104 CFU/ml. - Interventions: BAL samples will be cultured by standard methods and the minimal inhibitory concentration (MIC) of bacteria to the usual antibiotics will be determined using standard procedures. At the time of BAL collection, a rapid antibiogram will be performed by placing E-test antibiotic strips (AB Biodisk) directly onto Mueller-Hinton agar plates seeded with the BAL specimen (both by flooding and swabbing). E-test strips will be impregnated with cefoxitin, piperacillin-tazobactam, cefepime, imipenem, ciprofloxacin and amikacin. At 24 h, the E-test plates will be photographed and then examined separately by both a bacteriologist and a medical ICU physician following a consensus method. The final E-test results will be compared with the standard MIC cultures.
The therapy with Linezolid (LIN) represents better cost-effectiveness vs. Vancomycin (VAN) for the treatment of nosocomial Pneumonia associate to ventilator (VAP).
We aim to study whether the use of inhaled antibiotics may have an impact on the incidence of tracheobronchitis and pneumonia associated with the use of mechanical ventilation. The investigators hypothesize that this could be possible by decreasing the population of gram negative germs that colonize the lumen of tracheal tube and upper airways.
The purpose of this study is to understand the utilization patterns of doripenem in Asia Pacific, including the profile of the patients treated with carbapenems.
Triggering receptor expressed on myeloid cells (TREM)-1 is a recently described molecule that plays an important role in myeloid cell-activated inflammatory responses. The aim of this study was to investigate the evolutional change of soluble TREM-1 (sTREM-1) in bronchoalveolar lavage (BAL) fluid of clinically diagnosed ventilator-associated pneumonia (VAP) and its correlation with response to treatment and outcome.
One group of hospitals participated in a collaborative approach for healthcare quality improvement while another group was provided only a tool kit. The investigators' objective was to determine if the Collaborative would perform better at preventing central line-associated bloodstream infections (CLABSI) and ventilator-associated pneumonias (VAP). Hospitals were randomized to the Tool Kit or Collaborative conditions. The investigators' study evaluated the effects on care processes and outcomes of a multi-institutional quality improvement initiative focused on preventing hospital associate infections. The investigators' hypothesis was that the strategies for implementing safe critical care practice will differ in level of achievement whereby the Collaborative group will perform better than the Tool Kit group. The outcome measure comprised clinical event rates and an index of safe practices that represent a bundling of key process measures related to evidence-based practices for preventing catheter-related blood-stream infections and ventilator-associated pneumonia in the intensive care unit.
The purpose of this study is to assess the safety and efficacy of doripenem in participants with nosocomial pneumonia (inflammation of the lungs in which the lungs become heavy; pneumonia occurring at least 48 hours after hospital admission), complicated intra-abdominal (in belly) infections and complicated urinary tract infections (bladder infections).
The study is a prospective open trial conducted in 4 centers, and designed to determine if pharmacokinetic (PK) and pharmacodynamic (PD) parameters of imipenem, associated with amikacin as empirical therapy, impact microbiological and clinical outcome of patients with Gram negative bacilli (GNB) ventilator-associated pneumonia (VAP).
Head trauma and severe cerebral hemorrhage are major risk factors for development of ventilator-associated pneumonia. In a previous open labelled, single center study the investigators showed that repeated oropharyngeal decontamination with povidone-iodine may be an effective strategy to decrease the prevalence of ventilator-associated pneumonia in patients with head trauma. The present study aims to confirm these results in a multicenter, double blind study including patients suffering from head trauma or cerebral hemorrhage.
