Abstract
Laryngotracheal aspiration has a widely-held reputation as a primary cause of lower respiratory infections, such as pneumonia, and is a major concern of care providers of the seriously ill orelderly frail patient. Laryngeal mechanical inefficiency resulting in aspiration into the lower respiratory tract, by itself, is not the cause of pneumonia. It is but one of several factors that must be present simultaneously for pneumonia to develop. Aspiration of oral and gastric contentsoccurs often in healthy people of all ages and without significant pulmonary consequences. Inthe seriously ill or elderly frail patient, higher concentrations of pathogens in the contents of theaspirate are the primary catalyst for pulmonary infection development if in an immunocompromised lower respiratory system. The oral cavity is a complex and ever changing eco-environment striving to maintain homogeneity among the numerous microbial communities inhabiting its surfaces. Poor maintenance of these surfaces to prevent infection can result inpathogenic changes to these microbial communities and, with subsequent proliferation, can altermicrobial communities in the tracheal and bronchial passages. Higher bacterial pathogen concentrations mixing with oral secretions, or with foods, when aspirated into an immunecompromised lower respiratory complex, may result in bacterial aspiration pneumonia development, or other respiratory or systemic diseases. A large volume of clinical evidence makes it clear that oral cleaning regimens, when used in caring for ill or frail patients in hospitals and long-term care facilities, drastically reduce the incidence of respiratory infection and death. The purpose of this narrative review is to examine oral health as a required causative companionin bacterial aspiration pneumonia development, and the effectiveness of oral infection control inthe prevention of this disease.

Hurley J. Rebound Inverts the Staphylococcus aureus Bacteremia Prevention Effect of Antibiotic Based Decontamination Interventions in ICU Cohorts with Prolonged Length of Stay. Antibiotics (Basel) 2024; 13:316. [PMID: 38666992 PMCID: PMC11047347 DOI: 10.3390/antibiotics13040316] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2024] [Revised: 03/25/2024] [Accepted: 03/28/2024] [Indexed: 04/29/2024] Open
Abstract
Could rebound explain the paradoxical lack of prevention effect against Staphylococcus aureus blood stream infections (BSIs) with antibiotic-based decontamination intervention (BDI) methods among studies of ICU patients within the literature? Two meta-regression models were applied, each versus the group mean length of stay (LOS). Firstly, the prevention effects against S. aureus BSI [and S. aureus VAP] among 136 studies of antibiotic-BDI versus other interventions were analyzed. Secondly, the S. aureus BSI [and S. aureus VAP] incidence in 268 control and intervention cohorts from studies of antibiotic-BDI versus that among 165 observational cohorts as a benchmark was modelled. In model one, the meta-regression line versus group mean LOS crossed the null, with the antibiotic-BDI prevention effect against S. aureus BSI at mean LOS day 7 (OR 0.45; 0.30 to 0.68) inverted at mean LOS day 20 (OR 1.7; 1.1 to 2.6). In model two, the meta-regression line versus group mean LOS crossed the benchmark line, and the predicted S. aureus BSI incidence for antibiotic-BDI groups was 0.47; 0.09-0.84 percentage points below versus 3.0; 0.12-5.9 above the benchmark in studies with 7 versus 20 days mean LOS, respectively. Rebound within the intervention groups attenuated and inverted the prevention effect of antibiotic-BDI against S. aureus VAP and BSI, respectively. This explains the paradoxical findings.

Abstract
Topical povidone-iodine (PVP-I) is currently being considered as a potential preventive measure against the spread of COVID-19. Diluted PVP-I solutions have been historically used in Asia to treat upper respiratory tract infections (URTIs) by decreasing the bacterial and viral load on oropharyngeal mucosa to decrease the transmission of diseases. Efficacy of gargling 0.23% PVP-I mouthwash in Japan demonstrated to be efficacious in lowering the prevalence of URTIs when compared with placebo. The 0.23% concentration was used in vitro on severe acute respiratory syndrome coronavirus and Middle East respiratory syndrome coronavirus, which produced undetectable results after 30 seconds of exposure. Additionally, a recent study in 2020 proved the efficacy of PVP-I 0.45%-10% in reducing COVID-19 (SARS-CoV 2) viral load in vitro. Numerous clinical trials are being conducted to determine if there is a decrease in viral load, and thus transmission, when using oral or nasal topical PVP-I in COVID-19 patients. Because of the current lack of evidence for the use of PVP-I in vivo with COVID-19, it is recommended to await the clinical trial results before initiating this practice.

Abstract
BACKGROUND Ventilator-associated pneumonia (VAP) is defined as pneumonia developing in people who have received mechanical ventilation for at least 48 hours. VAP is a potentially serious complication in these patients who are already critically ill. Oral hygiene care (OHC), using either a mouthrinse, gel, swab, toothbrush, or combination, together with suction of secretions, may reduce the risk of VAP in these patients. OBJECTIVES To assess the effects of oral hygiene care (OHC) on incidence of ventilator-associated pneumonia in critically ill patients receiving mechanical ventilation in hospital intensive care units (ICUs). SEARCH METHODS Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 25 February 2020), the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, 2020, Issue 1), MEDLINE Ovid (1946 to 25 February 2020), Embase Ovid (1980 to 25 February 2020), LILACS BIREME Virtual Health Library (1982 to 25 February 2020) and CINAHL EBSCO (1937 to 25 February 2020). We also searched the VIP Database (January 2012 to 8 March 2020). The US National Institutes of Health Trials Registry (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform were searched for ongoing trials. No restrictions were placed on the language or date of publication when searching the electronic databases. SELECTION CRITERIA We included randomised controlled trials (RCTs) evaluating the effects of OHC (mouthrinse, gel, swab, toothbrush or combination) in critically ill patients receiving mechanical ventilation for at least 48 hours. DATA COLLECTION AND ANALYSIS At least two review authors independently assessed search results, extracted data and assessed risk of bias in included studies. We contacted study authors for additional information. We reported risk ratio (RR) for dichotomous outcomes and mean difference (MD) for continuous outcomes, using the random-effects model of meta-analysis when data from four or more trials were combined. MAIN RESULTS We included 40 RCTs (5675 participants), which were conducted in various countries including China, USA, Brazil and Iran. We categorised these RCTs into five main comparisons: chlorhexidine (CHX) mouthrinse or gel versus placebo/usual care; CHX mouthrinse versus other oral care agents; toothbrushing (± antiseptics) versus no toothbrushing (± antiseptics); powered versus manual toothbrushing; and comparisons of other oral care agents used in OHC (other oral care agents versus placebo/usual care, or head-to-head comparisons between other oral care agents). We assessed the overall risk of bias as high in 31 trials and low in two, with the rest being unclear. Moderate-certainty evidence from 13 RCTs (1206 participants, 92% adults) shows that CHX mouthrinse or gel, as part of OHC, probably reduces the incidence of VAP compared to placebo or usual care from 26% to about 18% (RR 0.67, 95% confidence intervals (CI) 0.47 to 0.97; P = 0.03; I2 = 66%). This is equivalent to a number needed to treat for an additional beneficial outcome (NNTB) of 12 (95% CI 7 to 128), i.e. providing OHC including CHX for 12 ventilated patients in intensive care would prevent one patient developing VAP. There was no evidence of a difference between interventions for the outcomes of mortality (RR 1.03, 95% CI 0.80 to 1.33; P = 0.86, I2 = 0%; 9 RCTs, 944 participants; moderate-certainty evidence), duration of mechanical ventilation (MD -1.10 days, 95% CI -3.20 to 1.00 days; P = 0.30, I2 = 74%; 4 RCTs, 594 participants; very low-certainty evidence) or duration of intensive care unit (ICU) stay (MD -0.89 days, 95% CI -3.59 to 1.82 days; P = 0.52, I2 = 69%; 5 RCTs, 627 participants; low-certainty evidence). Most studies did not mention adverse effects. One study reported adverse effects, which were mild, with similar frequency in CHX and control groups and one study reported there were no adverse effects. Toothbrushing (± antiseptics) may reduce the incidence of VAP (RR 0.61, 95% CI 0.41 to 0.91; P = 0.01, I2 = 40%; 5 RCTs, 910 participants; low-certainty evidence) compared to OHC without toothbrushing (± antiseptics). There is also some evidence that toothbrushing may reduce the duration of ICU stay (MD -1.89 days, 95% CI -3.52 to -0.27 days; P = 0.02, I2 = 0%; 3 RCTs, 749 participants), but this is very low certainty. Low-certainty evidence did not show a reduction in mortality (RR 0.84, 95% CI 0.67 to 1.05; P = 0.12, I2 = 0%; 5 RCTs, 910 participants) or duration of mechanical ventilation (MD -0.43, 95% CI -1.17 to 0.30; P = 0.25, I2 = 46%; 4 RCTs, 810 participants). AUTHORS' CONCLUSIONS Chlorhexidine mouthwash or gel, as part of OHC, probably reduces the incidence of developing ventilator-associated pneumonia (VAP) in critically ill patients from 26% to about 18%, when compared to placebo or usual care. We did not find a difference in mortality, duration of mechanical ventilation or duration of stay in the intensive care unit, although the evidence was low certainty. OHC including both antiseptics and toothbrushing may be more effective than OHC with antiseptics alone to reduce the incidence of VAP and the length of ICU stay, but, again, the evidence is low certainty. There is insufficient evidence to determine whether any of the interventions evaluated in the studies are associated with adverse effects.

Abstract
Aim The COVID‐19 pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) has put health care workers at risk when exposed to aerosolized viral particles during upper airway mucosal surgery. The objective of this review was to discuss topical preparations that could be utilized preoperatively to help to decrease viral load and potentially reduce the risks of viral transmission. Methods A PubMed/MEDLINE database review of articles was performed querying topical preparations with virucidal activity against coronaviruses. Results Povidone‐iodine (PVP‐I) solutions ranging from 0.23% to 7% have been found to demonstrate highly effective virucidal activity against a broad range of viruses including several coronaviruses responsible for recent epidemics including SARS‐CoV‐1 and MERS‐CoV. Conclusions While specific evidence regarding SARS‐CoV‐2 is lacking, PVP‐I‐based preparations have been successfully demonstrated to reduce viral loads of coronaviruses. They are relatively safe to use in the upper airway and may reduce risk of SARS‐CoV‐2 aerosolization during upper airway mucosal surgery.

Abstract
Hospital-acquired infections are common in neurointensive care units. We sought to review interventions which may reduce infection rates in neurocritically ill populations. We conducted a systematic review of studies targeting adult patients in neuro-intensive care units (neuro-ICUs) with an intervention designed to prevent ICU-acquired infections. Our outcome of interest was change in the prevalence or rates of infection between active and control arms of these studies. We excluded studies based on the following criteria: no English full-text version available; pediatric population; non-neurosciences ICU population; pre- or intraoperative methods to prevent infection; lack of discrete data for infection rates/prevalence; studies that were purely observational in nature and did not test an intervention; and studies performed in resource limited settings. We initially retrieved 3716 results by searching the following databases: PubMed/MEDLINE, EMBASE via Ovid, and Cochrane CENTRAL via Ovid. No date or language limits were used in the search. Computerized deduplication was conducted using EndNote followed by a confirmatory manual review resulting in 3414 citations. An additional 19 manuscripts were identified through review of references. The screening process followed a standard protocol, using two screeners at the title/abstract level to determine relevance and at the full-text level to determine eligibility for inclusion. The 3427 titles/abstracts were independently screened by two board-certified neurointensivists to determine relevance for full-text review, and 3248 were rejected. The remaining 179 abstracts were reviewed in full text using predetermined inclusion/exclusion criteria. Ultimately, 75 articles met our inclusion criteria and were utilized in the final analysis. The reviewed literature highlights the need for collaborative, multi-disciplinary, and multi-pronged approaches to reduce infections. Rates of VRI, SSI, VAP, CAUTI, and CLABSI can approach zero with persistence and a team-based approach.

Abstract
Background Most deaths following severe traumatic brain injury follow decisions to withdraw life-sustaining therapies. However, the incidence of the withdrawal of life-sustaining therapies and its potential impact on research data interpretation have been poorly characterized. The aim of this systematic review was to assess the reporting and the impact of withdrawal of life-sustaining therapies in randomized clinical trials of patients with severe traumatic brain injury. Methods We searched Medline, Embase, Cochrane Central, BIOSIS, and CINAHL databases and references of included trials. All randomized controlled trials published between January 2002 and August 2015 in the six highest impact journals in general medicine, critical care medicine, and neurocritical care (total of 18 journals) were considered for eligibility. Randomized controlled trials were included if they enrolled adult patients with severe traumatic brain injury (Glasgow Coma Scale ≤ 8) and reported data on mortality. Our primary objective was to assess the proportion of trials reporting the withdrawal of life-sustaining therapies in a publication. Our secondary objectives were to describe the overall mortality rate, the proportion of deaths following the withdrawal of life-sustaining therapies, and to assess the impact of the withdrawal of life-sustaining therapies on trial results. Results From 5987 citations retrieved, we included 41 randomized trials (n = 16,364, ranging from 11 to 10,008 patients). Overall mortality was 23% (range = 3%-57%). Withdrawal of life-sustaining therapies was reported in 20% of trials (8/41, 932 patients in trials) and the crude number of deaths due to the withdrawal of life-sustaining therapies was reported in 17% of trials (7/41, 884 patients in trials). In these trials, 63% of deaths were associated with the withdrawal of life-sustaining therapies (105/168). An analysis carried out by imputing a 4% differential rate in instances of withdrawal of life-sustaining therapies between study groups yielded different results and conclusions in one third of the trials. Conclusion Data on the withdrawal of life-sustaining therapies are incompletely reported in randomized controlled trials of patients with severe traumatic brain injury. Given the high proportion of deaths due to the withdrawal of life-sustaining therapies in severe traumatic brain injury patients, and the potential of this medical decision to influence the results of clinical trials, instances of withdrawal of life-sustaining therapies should be systematically reported in clinical trials in this group of patients.

Unusually High Incidences of Staphylococcus aureus Infection within Studies of Ventilator Associated Pneumonia Prevention Using Topical Antibiotics: Benchmarking the Evidence Base. Microorganisms 2018; 6:microorganisms6010002. [PMID: 29300363 PMCID: PMC5874616 DOI: 10.3390/microorganisms6010002] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2017] [Revised: 12/29/2017] [Accepted: 01/02/2018] [Indexed: 01/08/2023] Open
Abstract
Selective digestive decontamination (SDD, topical antibiotic regimens applied to the respiratory tract) appears effective for preventing ventilator associated pneumonia (VAP) in intensive care unit (ICU) patients. However, potential contextual effects of SDD on Staphylococcus aureus infections in the ICU remain unclear. The S. aureus ventilator associated pneumonia (S. aureus VAP), VAP overall and S. aureus bacteremia incidences within component (control and intervention) groups within 27 SDD studies were benchmarked against 115 observational groups. Component groups from 66 studies of various interventions other than SDD provided additional points of reference. In 27 SDD study control groups, the mean S. aureus VAP incidence is 9.6% (95% CI; 6.9–13.2) versus a benchmark derived from 115 observational groups being 4.8% (95% CI; 4.2–5.6). In nine SDD study control groups the mean S. aureus bacteremia incidence is 3.8% (95% CI; 2.1–5.7) versus a benchmark derived from 10 observational groups being 2.1% (95% CI; 1.1–4.1). The incidences of S. aureus VAP and S. aureus bacteremia within the control groups of SDD studies are each higher than literature derived benchmarks. Paradoxically, within the SDD intervention groups, the incidences of both S. aureus VAP and VAP overall are more similar to the benchmarks.

Abstract
BACKGROUND Oral care of intubated patients is essential to the prevention of infection and patient discomfort. However, barriers to oral access and delivery of oral care have received little attention. OBJECTIVE To determine prevalence and predictors of oral access difficulty. DESIGN A prospective, observational, multi-center study. SETTINGS Four intensive care units in Toronto, Canada. PARTICIPANTS Adult patients orally intubated for ≥48 h. METHODS We screened consecutive admissions once a week to identify eligible participants. We observed each patient and asked the patient's nurse about presence or absence of difficulty accessing the mouth to deliver oral care across three categories: (1) visualizing inside the mouth; (2) obtaining patient cooperation, or (3) inserting instruments for delivery of oral care. We asked nurses to identify presence of patient behaviors contributing to oral access difficulty and perceived level of difficulty on a Likert response scale. We examined patient and treatment characteristics associated with extreme difficulty (i.e., difficulty in all 3 categories) using a generalized estimating equation regression model. RESULTS A total of 428 patients were observed, 58% admitted with a medical diagnosis. More than half (57%) had ≥2 oral devices up to maximum of 4. Oral care difficulty was identified in 83% of patients and rated as moderate to high for 217 (51%). Difficulty concerned visibility (74%), patient cooperation (55%), and space to insert instruments (53%). Patient behaviors contributing difficulty included coughing/gagging (60%), mouth closing (49%), biting (45%) and localizing (27%) during care. Variables associated with extreme difficulty included neurological (OR 1.92, 95% CI 1.42-2.60) or trauma admission (OR 1.83, 95% CI 1.16-2.89), lack of pain assessment or treatment in the 4 h prior to oral care (OR 1.43, 95% CI 1.14-1.80), more oral devices (OR 1.40, 95% CI 1.05-1.87), and duration of intubation (OR 1.05, 95% CI 1.01-1.10). Absence of documented agitation in the 4 h prior to oral care was associated with less difficulty (OR 0.68, 95% CI 0.54-0.86). CONCLUSIONS Oral care is complex and difficulties are experienced in a vast majority of intubated patients. Some difficulties are amenable to correction such as pain management.

Abstract
The scope and purpose of this work is 2-fold: to synthesize the available evidence and to translate it into recommendations. This document provides recommendations only when there is evidence to support them. As such, they do not constitute a complete protocol for clinical use. Our intention is that these recommendations be used by others to develop treatment protocols, which necessarily need to incorporate consensus and clinical judgment in areas where current evidence is lacking or insufficient. We think it is important to have evidence-based recommendations to clarify what aspects of practice currently can and cannot be supported by evidence, to encourage use of evidence-based treatments that exist, and to encourage creativity in treatment and research in areas where evidence does not exist. The communities of neurosurgery and neuro-intensive care have been early pioneers and supporters of evidence-based medicine and plan to continue in this endeavor. The complete guideline document, which summarizes and evaluates the literature for each topic, and supplemental appendices (A-I) are available online at https://www.braintrauma.org/coma/guidelines.

Abstract
BACKGROUND Ventilator-associated pneumonia (VAP) is defined as pneumonia developing in people who have received mechanical ventilation for at least 48 hours. VAP is a potentially serious complication in these patients who are already critically ill. Oral hygiene care (OHC), using either a mouthrinse, gel, toothbrush, or combination, together with aspiration of secretions, may reduce the risk of VAP in these patients. OBJECTIVES To assess the effects of oral hygiene care on incidence of ventilator-associated pneumonia in critically ill patients receiving mechanical ventilation in hospital intensive care units (ICUs). SEARCH METHODS We searched the following electronic databases: Cochrane Oral Health's Trials Register (to 17 December 2015), the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, 2015, Issue 11), MEDLINE Ovid (1946 to 17 December 2015), Embase Ovid (1980 to 17 December 2015), LILACS BIREME Virtual Health Library (1982 to 17 December 2015), CINAHL EBSCO (1937 to 17 December 2016), Chinese Biomedical Literature Database (1978 to 14 January 2013), China National Knowledge Infrastructure (1994 to 14 January 2013), Wan Fang Database (January 1984 to 14 January 2013) and VIP Database (January 2012 to 4 May 2016). We searched ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform for ongoing trials to 17 December 2015. We placed no restrictions on the language or date of publication when searching the electronic databases. SELECTION CRITERIA We included randomised controlled trials (RCTs) evaluating the effects of OHC (mouthrinse, swab, toothbrush or combination) in critically ill patients receiving mechanical ventilation for at least 48 hours. DATA COLLECTION AND ANALYSIS At least two review authors independently assessed search results, extracted data and assessed risk of bias in included studies. We contacted study authors for additional information. We pooled data from trials with similar interventions and outcomes. We reported risk ratio (RR) for dichotomous outcomes and mean difference (MD) for continuous outcomes, using random-effects models unless there were fewer than four studies. MAIN RESULTS We included 38 RCTs (6016 participants). There were four main comparisons: chlorhexidine (CHX) mouthrinse or gel versus placebo/usual care; toothbrushing versus no toothbrushing; powered versus manual toothbrushing; and comparisons of oral care solutions. We assessed the overall risk of bias as low in five trials (13%), high in 26 trials (68%), and unclear in seven trials (18%). We did not consider the risk of bias to be serious when assessing the quality of evidence (GRADE) for VAP incidence, but we downgraded other outcomes for risk of bias.High quality evidence from 18 RCTs (2451 participants, 86% adults) shows that CHX mouthrinse or gel, as part of OHC, reduces the risk of VAP compared to placebo or usual care from 25% to about 19% (RR 0.74, 95% confidence intervals (CI) 0.61 to 0.89, P = 0.002, I2 = 31%). This is equivalent to a number needed to treat for an additional beneficial outcome (NNTB) of 17 (95% CI 10 to 33), which indicates that for every 17 ventilated patients in intensive care receiving OHC including chlorhexidine, one outcome of VAP would be prevented. There is no evidence of a difference between CHX and placebo/usual care for the outcomes of mortality (RR 1.09, 95% CI 0.96 to 1.23, P = 0.18, I2 = 0%, 15 RCTs, 2163 participants, moderate quality evidence), duration of mechanical ventilation (MD -0.09 days, 95% CI -1.73 to 1.55 days, P = 0.91, I2 = 36%, five RCTs, 800 participants, low quality evidence), or duration of intensive care unit (ICU) stay (MD 0.21 days, 95% CI -1.48 to 1.89 days, P = 0.81, I2 = 9%, six RCTs, 833 participants, moderate quality evidence). There is insufficient evidence to determine the effect of CHX on duration of systemic antibiotics, oral health indices, caregivers' preferences or cost. Only two studies reported any adverse effects, and these were mild with similar frequency in CHX and control groups.We are uncertain as to the effects of toothbrushing (± antiseptics) on the outcomes of VAP (RR 0.69, 95% CI 0.44 to 1.09, P = 0.11, I2 = 64%, five RCTs, 889 participants, very low quality evidence) and mortality (RR 0.87, 95% CI 0.70 to 1.09, P = 0.24, I2 = 0%, five RCTs, 889 participants, low quality evidence) compared to OHC without toothbrushing (± antiseptics). There is insufficient evidence to determine whether toothbrushing affects duration of mechanical ventilation, duration of ICU stay, use of systemic antibiotics, oral health indices, adverse effects, caregivers' preferences or cost.Only one trial (78 participants) compared use of a powered toothbrush with a manual toothbrush, providing insufficient evidence to determine the effect on any of the outcomes of this review.Fifteen trials compared various other oral care solutions. There is very weak evidence that povidone iodine mouthrinse is more effective than saline/placebo (RR 0.69, 95% CI 0.50 to 0.95, P = 0.02, I2 = 74%, three studies, 356 participants, high risk of bias), and that saline rinse is more effective than saline swab (RR 0.47, 95% CI 0.37 to 0.62, P < 0.001, I2 = 84%, four studies, 488 participants, high risk of bias) in reducing VAP. Due to variation in comparisons and outcomes among trials, there is insufficient evidence concerning the effects of other oral care solutions. AUTHORS' CONCLUSIONS OHC including chlorhexidine mouthwash or gel reduces the risk of developing ventilator-associated pneumonia in critically ill patients from 25% to about 19%. However, there is no evidence of a difference in the outcomes of mortality, duration of mechanical ventilation or duration of ICU stay. There is no evidence that OHC including both antiseptics and toothbrushing is different from OHC with antiseptics alone, and some weak evidence to suggest that povidone iodine mouthrinse is more effective than saline/placebo, and saline rinse is more effective than saline swab in reducing VAP. There is insufficient evidence to determine whether powered toothbrushing or other oral care solutions are effective in reducing VAP. There is also insufficient evidence to determine whether any of the interventions evaluated in the studies are associated with adverse effects.

Abstract
AIMS The aim of the study was to determine the effect of hydrogen peroxide (HP) mouthwash on the incidence of ventilator associated pneumonia (VAP) in patients admitted to the intensive care unit (ICU). METHODS This was a randomized clinical trial conducted on 68 patients. The intervention group used 3% HP as mouthwash and the control group used mouthwashes with 0.9% normal saline (NS) twice a day. Data were collected using a questionnaire and the Modified Clinical Pulmonary Infection Score (MCPIS). MCPIS includes five items, body temperature: white blood cell count, pulmonary secretions, the ratio of pressure of arterial oxygen (PaO2) to fraction of inspired oxygen (FiO2), and the chest X-ray. Each of these items scored 0-2. Scores ≥6 were considered as VAP signs. The SPSS-20 software was employed to analyze the data. RESULTS In total, 14.7% patients of the HP group and 38.2% patients of the NS group contracted VAP. The risk of VAP in the NS group was 2.60 times greater than that in the HP group (RR=2.60, 95% CI: 1.04-6.49, p=0.0279). The mean±SD MCPIS was calculated as 3.91±1.35 in the HP group and 4.65±1.55 in the NS group, a difference statistically significant (p=0.042). There were no significant differences in the risk factors for VAP between the two groups. CONCLUSION HP mouthwash was found more effective than NS in reducing VAP. HP mouthwash can therefore be used in routine nursing care for reducing VAP.

Abstract
AIMS To better inform medical practitioners on the role of antiseptics in oropharyngeal health and disease, this article focuses on povidone-iodine (PVP-I), an established and widely-available antiseptic agent. METHODOLOGY Review of the anti-infective profile, efficacy and safety of PVP-I in managing common upper respiratory tract infections such as the common cold, influenza and tonsillo-pharyngitis, as well as oral complications resulting from cancer treatment (oral mucositis), and dental conditions (periodontitis, caries). RESULTS Antiseptics with broad-spectrum anti-infective activity and low resistance potential offer an attractive option in both infection control and prevention. While there is some evidence of benefit of antiseptics in a variety of clinical settings that include dental and oral hygiene, dermatology, oncology, and pulmonology, there appears to be discordance between the evidence-base and practice. This is especially apparent in the management and prevention of oropharyngeal infections, for which the use of antiseptics varies considerably between clinical practices, and is in marked contrast to their dermal application, where they are extensively used as both a prophylaxis and a treatment of skin and wound infections, thus minimising the use of antibiotics. CONCLUSION The link between oral and oropharyngeal health status and susceptibility to infection has long been recognised. The high rates of antibiotic misuse and subsequent development of bacterial resistance (e.g. increasing vancomycin-resistant enterococci (VRE) and methicillin-resistant Staphylococcus aureus (MRSA)) in large parts of the world, especially across Asia Pacific, highlight the need for identifying alternative antimicrobials that would minimise the use of these medications. This, together with recent large-scale outbreaks of, for example, avian and swine influenza virus, further underline the importance of an increasing armamentarium for infection prevention and control.

Abstract
BACKGROUND Among methods for preventing pneumonia and possibly also bacteremia in intensive care unit (ICU) patients, Selective Digestive Decontamination (SDD) appears most effective within randomized concurrent controlled trials (RCCT's) although more recent trials have been cluster randomized. However, of the SDD components, whether protocolized parenteral antibiotic prophylaxis (PPAP) is required, and whether the topical antibiotic actually presents a contextual hazard, remain unresolved. The objective here is to compare the bacteremia rates and patterns of isolates in SDD-RCCT's versus the broader evidence base. METHODS Bacteremia incidence proportion data were extracted from component (control and intervention) groups decanted from studies investigating antibiotic (SDD) or non-antibiotic methods of VAP prevention and summarized using random effects meta-analysis of study and group level data. A reference category of groups derived from purely observational studies without any prevention method under study provided a benchmark incidence. RESULTS Within SDD RCCTs, the mean bacteremia incidence among concurrent component groups not exposed to PPAP (27 control; 17.1%; 13.1-22.1% and 12 intervention groups; 16.2%; 9.1-27.3%) is double that of the benchmark bacteremia incidence derived from 39 benchmark groups (8.3; 6.8-10.2%) and also 20 control groups from studies of non-antibiotic methods (7.1%; 4.8 - 10.5). There is a selective increase in coagulase negative staphylococci (CNS) but not in Pseudomonas aeruginosa among bacteremia isolates within control groups of SDD-RCCT's versus benchmark groups with data available. CONCLUSIONS The topical antibiotic component of SDD presents a major contextual hazard toward bacteremia against which the PPAP component partially mitigates.

Abstract
Introduction Fever is associated with a poor outcome in severely brain-injured patients, and its control is one of the therapies used in this condition. But, fever suppression may promote infection, and severely brain-injured patients are frequently exposed to infectious diseases, particularly ventilator-associated pneumonia (VAP). Therefore, we designed a study to explore the role of a fever control protocol in VAP development during neuro-intensive care. Methods An observational study was performed on severely brain-injured patients hospitalized in a university ICU. The primary goal was to assess whether fever control was a risk factor for VAP in a prospective cohort in which a fever control protocol was applied and in a historical control group. Moreover, the density of VAP incidence was compared between the two groups. The statistical analysis was based on a competing risk model multivariate analysis. Results The study included 189 brain-injured patients (intervention group, n = 98, and historical control group, n = 91). The use of a fever control protocol was an independent risk factor for VAP (hazard ratio 2.73, 95% confidence interval (1.38, 5.38; P = 0.005)). There was a significant increase in the incidence of VAP in patients treated with a fever control protocol (26.1 versus 12.5 VAP cases per 1000 days of mechanical ventilation). In cases in which a fever control protocol was applied for >3 days, we observed a higher rate of VAP in comparison with the rate among patients treated for ≤3 days. Conclusions Fever control in brain-injured patients was a major risk factor for VAP occurrence, particularly when applied for >3 days.

Abstract
Oral hygiene is a critical element of patient care, particularly among patients who need ventilator-assisted equipment. The objective of this study was to explore the current status of oral care practices, attitudes, education and knowledge among intensive care unit (ICU) nurses caring for ventilator-assisted patients in 3A hospitals in mainland China. To achieve this aim, an 18-item self-assessment questionnaire was mailed to head ICU nurses in 189 Grade 3A hospitals. Additional data were collected through in-person interviews at 38 ICUs throughout Sichuan, Shanxi, Jiangsu provinces, as well as Chongqing and Beijing. We found that most ICUs conducted oral examinations at patient admission, and that this care was largely provided by nurses. The most common oral care methods were foam swabs and mouth rinse containing antibiotics or disinfectants. Although the majority of ICUs provided continuing training for oral care, and most training was conducted by head nurses, the content and scope of training were not consistent among the hospitals in the study. The most popular sources of oral care knowledge were academic journals, Internet and professional books. Overall, it is clear that an evidence-based oral care standard manual is urgently needed for oral practice in ICUs in mainland China.

Abstract
OBJECTIVE To evaluate the efficacy and safety of oral care with povidone-iodine on the occurrence of ventilator-associated pneumonia in a high-risk population. DESIGN A multicenter, placebo-controlled, randomized, double-blind, two-parallel-group trial performed between May 2008 and May 2011. SETTING Six ICUs in France. PATIENTS One hundred seventy-nine severely brain-injured patients (Glasgow Coma Scale ≤ 8) or cerebral hemorrhage expected to be mechanically ventilated for more than 24 hours. INTERVENTIONS Participants were randomly assigned to receive oropharyngeal care with povidone-iodine (n = 91) or placebo (n = 88) six times daily until mechanical ventilation withdrawal. MEASUREMENTS AND MAIN RESULTS Primary endpoint was the rate of ventilator-associated pneumonia. Secondary endpoint included the rates of ventilator-associated tracheobronchitis and acute respiratory distress syndrome and patient's outcome. The number of patients evaluable for the primary endpoint (preplanned modified intention-to-treat population) was 150 (78 in the povidone-iodine group, 72 in the placebo group). Ventilator-associated pneumonia occurred in 24 patients (31%) in the povidone-iodine group and 20 (28%) in the placebo group (relative risk, 1.11 [95% CI, 0.67-1.82]; p = 0.69). There was no significant difference between the two groups for ventilator-associated tracheobronchitis: eight patients (10%) in the povidone-iodine group and five patients (7%) in the placebo group (relative risk, 1.48 [95% CI, 0.51-4.31]; p = 0.47). Acute respiratory distress syndrome occurred in five patients in the povidone-iodine group but not in the placebo group (p = 0.06). There was no difference between groups for ICU and hospital lengths of stay, as well as ICU and 90-day mortality. CONCLUSIONS There is no evidence to recommend oral care with povidone-iodine to prevent ventilator-associated pneumonia in high-risk patients. Furthermore, this strategy seems to increase the rate of acute respiratory distress syndrome.

Abstract
RATIONALE Mechanical ventilation is associated with morbidity in patients with brain injury. OBJECTIVES This study aims to assess the effectiveness of an extubation readiness bundle to decrease ventilator time in patients with brain injury. METHODS Before-after design in two intensive care units (ICUs) in one university hospital. Brain-injured patients ventilated more than 24 hours were evaluated during two phases (a 3-yr control phase followed by a 22-mo intervention phase). Bundle components were protective ventilation, early enteral nutrition, standardization of antibiotherapy for hospital-acquired pneumonia, and systematic approach to extubation. The primary endpoint was the duration of mechanical ventilation. MEASUREMENTS AND MAIN RESULTS A total of 299 and 200 patients, respectively, were analyzed in the control and the intervention phases of this before-after study. The intervention phase was associated with lower tidal volume (P < 0.01), higher positive end-expiratory pressure (P < 0.01), and higher enteral intake in the first 7 days (P = 0.01). The duration of mechanical ventilation was 14.9 ± 11.7 days in the control phase and 12.6 ± 10.3 days in the intervention phase (P = 0.02). The hazard ratio for extubation was 1.28 (95% confidence interval [CI], 1.04-1.57; P = 0.02) in the intervention phase. Adjusted hazard ratio was 1.40 (95% CI, 1.12-1.76; P < 0.01) in multivariate analysis and 1.34 (95% CI, 1.03-1.74; P = 0.02) in propensity score-adjusted analysis. ICU-free days at Day 90 increased from 50 ± 33 in the control phase to 57 ± 29 in the intervention phase (P < 0.01). Mortality at Day 90 was 28.4% in the control phase and 23.5% in the intervention phase (P = 0.22). CONCLUSIONS The implementation of an evidence-based extubation readiness bundle was associated with a reduction in the duration of ventilation in patients with brain injury.

Abstract
BACKGROUND Ventilator-associated pneumonia (VAP) is defined as pneumonia developing in persons who have received mechanical ventilation for at least 48 hours. VAP is a potentially serious complication in these patients who are already critically ill. Oral hygiene care (OHC), using either a mouthrinse, gel, toothbrush, or combination, together with aspiration of secretions may reduce the risk of VAP in these patients. OBJECTIVES To assess the effects of OHC on the incidence of VAP in critically ill patients receiving mechanical ventilation in intensive care units (ICUs) in hospitals. SEARCH METHODS We searched the Cochrane Oral Health Group's Trials Register (to 14 January 2013), CENTRAL (The Cochrane Library 2012, Issue 12), MEDLINE (OVID) (1946 to 14 January 2013), EMBASE (OVID) (1980 to 14 January 2013), LILACS (BIREME) (1982 to 14 January 2013), CINAHL (EBSCO) (1980 to 14 January 2013), Chinese Biomedical Literature Database (1978 to 14 January 2013), China National Knowledge Infrastructure (1994 to 14 January 2013), Wan Fang Database (January 1984 to 14 January 2013), OpenGrey and ClinicalTrials.gov (to 14 January 2013). There were no restrictions regarding language or date of publication. SELECTION CRITERIA We included randomised controlled trials (RCTs) evaluating the effects of OHC (mouthrinse, swab, toothbrush or combination) in critically ill patients receiving mechanical ventilation. DATA COLLECTION AND ANALYSIS Two review authors independently assessed all search results, extracted data and undertook risk of bias. We contacted study authors for additional information. Trials with similar interventions and outcomes were pooled reporting odds ratios (OR) for dichotomous outcomes and mean differences (MD) for continuous outcomes using random-effects models unless there were fewer than four studies. MAIN RESULTS Thirty-five RCTs (5374 participants) were included. Five trials (14%) were assessed at low risk of bias, 17 studies (49%) were at high risk of bias, and 13 studies (37%) were assessed at unclear risk of bias in at least one domain. There were four main comparisons: chlorhexidine (CHX mouthrinse or gel) versus placebo/usual care, toothbrushing versus no toothbrushing, powered versus manual toothbrushing and comparisons of oral care solutions.There is moderate quality evidence from 17 RCTs (2402 participants, two at high, 11 at unclear and four at low risk of bias) that CHX mouthrinse or gel, as part of OHC, compared to placebo or usual care is associated with a reduction in VAP (OR 0.60, 95% confidence intervals (CI) 0.47 to 0.77, P < 0.001, I(2) = 21%). This is equivalent to a number needed to treat (NNT) of 15 (95% CI 10 to 34) indicating that for every 15 ventilated patients in intensive care receiving OHC including chlorhexidine, one outcome of VAP will be prevented. There is no evidence of a difference between CHX and placebo/usual care in the outcomes of mortality (OR 1.10, 95% CI 0.87 to 1.38, P = 0.44, I(2) = 2%, 15 RCTs, moderate quality evidence), duration of mechanical ventilation (MD 0.09, 95% CI -0.84 to 1.01 days, P = 0.85, I(2) = 24%, six RCTs, moderate quality evidence), or duration of ICU stay (MD -0.21, 95% CI -1.48 to 1.89 days, P = 0.81, I(2) = 9%, six RCTs, moderate quality evidence). There was insufficient evidence to determine whether there is a difference between CHX and placebo/usual care in the outcomes of duration of use of systemic antibiotics, oral health indices, microbiological cultures, caregivers preferences or cost. Only three studies reported any adverse effects, and these were mild with similar frequency in CHX and control groups.From three trials of children aged from 0 to 15 years (342 participants, moderate quality evidence) there is no evidence of a difference between OHC with CHX and placebo for the outcomes of VAP (OR 1.07, 95% CI 0.65 to 1.77, P = 0.79, I(2) = 0%), or mortality (OR 0.73, 95% CI 0.41 to 1.30, P = 0.28, I(2) = 0%), and insufficient evidence to determine the effect on the outcomes of duration of ventilation, duration of ICU stay, use of systemic antibiotics, plaque index, microbiological cultures or adverse effects, in children.Based on four RCTs (828 participants, low quality evidence) there is no evidence of a difference between OHC including toothbrushing (± CHX) compared to OHC without toothbrushing (± CHX) for the outcome of VAP (OR 0.69, 95% CI 0.36 to 1.29, P = 0.24 , I(2) = 64%) and no evidence of a difference for mortality (OR 0.85, 95% CI 0.62 to 1.16, P = 0.31, I(2) = 0%, four RCTs, moderate quality evidence). There is insufficient evidence to determine whether there is a difference due to toothbrushing for the outcomes of duration of mechanical ventilation, duration of ICU stay, use of systemic antibiotics, oral health indices, microbiological cultures, adverse effects, caregivers preferences or cost.Only one trial compared use of a powered toothbrush with a manual toothbrush providing insufficient evidence to determine the effect on any of the outcomes of this review.A range of other oral care solutions were compared. There is some weak evidence that povidone iodine mouthrinse is more effective than saline in reducing VAP (OR 0.35, 95% CI 0.19 to 0.65, P = 0.0009, I(2) = 53%) (two studies, 206 participants, high risk of bias). Due to the variation in comparisons and outcomes among the trials in this group there is insufficient evidence concerning the effects of other oral care solutions on the outcomes of this review. AUTHORS' CONCLUSIONS Effective OHC is important for ventilated patients in intensive care. OHC that includes either chlorhexidine mouthwash or gel is associated with a 40% reduction in the odds of developing ventilator-associated pneumonia in critically ill adults. However, there is no evidence of a difference in the outcomes of mortality, duration of mechanical ventilation or duration of ICU stay. There is no evidence that OHC including both CHX and toothbrushing is different from OHC with CHX alone, and some weak evidence to suggest that povidone iodine mouthrinse is more effective than saline in reducing VAP. There is insufficient evidence to determine whether powered toothbrushing or other oral care solutions are effective in reducing VAP.

Abstract
OBJECTIVE We investigated the overall immune response to pathogens in brain-injured patients, and assessed its relationship to nosocomial pneumonia. DESIGN Observational study. SETTING Two surgical ICUs of a single institution. PATIENTS Severe brain-injured patients (n = 32) requiring mechanical ventilation and sex- and age-matched healthy donors (n = 25). INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS We evaluated, ex vivo, the ability of peripheral blood mononuclear cells from brain injury patients to develop an effective granulomatous response to mycobacteria. Thirty-two consecutive patients (25 traumatic brain injured and seven subarachnoid hemorrhage) were included. Median Glasgow Coma Scale was 7 (5-8). Thirteen (41%) patients developed nosocomial pneumonia. Peripheral blood mononuclear cells from brain-injured patients with nosocomial pneumonia generated significantly fewer mature granulomas compared with brain-injured patients without nosocomial pneumonia and with healthy donors. The percentage of multinucleated giant cells was lower in brain-injured patients without nosocomial pneumonia (1% [range: 0%-7%]) and in brain-injured patients with nosocomial pneumonia (4% [range: 2%-5%]) compared with healthy donors (20% [range: 15%-28%]). The blood levels of γδ T cells were significantly increased in brain-injured patients without nosocomial pneumonia (66% [range: 34%-69%]) compared with healthy donors (23% [range: 8%-61%]) and was not altered in brain-injured patients with nosocomial pneumonia (31% [range: 12%-44%]). The percentage of γδ T cells in granulomas was significantly decreased in brain injury patients with nosocomial pneumonia (5% [range: 4%-43%]) compared with healthy donors (43% [range: 19%-54%]) and was not significantly altered in brain-injured patients without nosocomial pneumonia (26% [range: 10%-41%]). The blood levels of natural killer cells were not altered in brain-injured patients. The percentage of natural killer cells in granulomas was significantly decreased in brain-injured patients with nosocomial pneumonia (3% [range: 1%-9%]) compared with brain-injured patients without nosocomial pneumonia (16% [range: 6%-29%]) and with healthy donors (17% [range: 10%-29%]). CONCLUSIONS Brain-injured patients experienced a maturation defect of the ex vivo granulomatous response involving monocytes as well as natural killer cells and γδ T cells.

Abstract
Infections remain a leading cause of death in burn patients. This is as a result of loss of the environmental barrier function of the skin predisposing these patients to microbial colonization leading to invasion. Therefore, reconstitution of the environmental barrier by debriding the devitalized tissue and wound closure with application of allograft versus autograft is of optimal importance.

Abstract
Although complete healing may appear to be the logical goal for most patients and clinicians, some wounds do not have the potential to heal due to a number of factors such as inadequate vasculature, coexisting medical conditions and medications that prohibit the healing process. Local management of wounds that are considered to have poor potential for healing remains elusive. The purpose of this article is to review the evidence that supports the use of topical antiseptic agents in non-healable wounds. Retrospective chart audit was conducted to evaluate the use of povidone iodine in the management of wounds that were deemed to have poor healing potential.

Abstract
BACKGROUND It is unclear if placing feeding tubes postpylorically to prevent respiratory complications is worth the extra effort. This study sought to determine the extent to which aspiration and pneumonia are associated with feeding site (controlling for the effects of severity of illness, degree of head-of-bed elevation, level of sedation, and use of gastric suction). METHODS A retrospective analysis was performed on a large data set gathered prospectively to evaluate aspiration in critically ill, mechanically ventilated patients. Feeding site was designated by attending physicians and confirmed by radiography. Each patient participated in the study for 3 consecutive days, with pneumonia assessed by the simplified Clinical Pulmonary Infection Score on the fourth day. Tracheal secretions were assayed for pepsin in a research laboratory; the presence of pepsin served as a proxy for aspiration. A total of 428 patients were included in the regression analyses performed to address the research objectives. RESULTS As compared with the stomach, the percentage of aspiration was 11.6% lower when feeding tubes were in the first portion of the duodenum, 13.2% lower when in the second/third portions of the duodenum, and 18.0% lower when in the fourth portion of the duodenum and beyond (all significant at P < .001). Pneumonia occurred less often when feedings were introduced at or beyond the second portion of the duodenum (P = .020). CONCLUSIONS The findings support feeding critically ill patients with numerous risk factors for aspiration in the mid-duodenum and beyond to reduce the risk of aspiration and associated pneumonia.

Abstract
OBJECTIVE To determine the effectiveness of oral care in preventing pneumonia associated with mechanical ventilation (VAP). METHOD A search was made for randomised clinical trials (RCTs) in CINAHL, Cuiden Plus, Pub Med, EMBASE, ENFISPO, Cochrane, Cuiden, DARE, EBE, JBI, and reverse lookup from the beginning of indexing of each database up to 3 May 2010. There were no restrictions on language, age, sex or underlying disease. RCTs that compared oral care and determined their effectiveness in preventing VAP were included. The different interventions were analysed to determine the most effective and protective. Epidat 3.1 was used for analysing the data. Out of a total of 858 articles reviewed, only 14 met the inclusion criteria. RESULTS Using a random effects model statistically significant results were found in favour of chlorhexidine as a protective factor against VAP (RR=0.7065, 95% CI: 0.5568-0.8963). The application of 0.12% chlorhexidine twice a day gave an RR: 0.69, 95% CI: 0.53-0.91 and 0.2% chlorhexidine four times daily: (RR=0.53, 95% CI: 0.31 to 0.90), being statistically significant. The application of 0.12% and 0.2% chlorhexidine three times a day and brushing did not give statistically significant results. CONCLUSIONS The use of chlorhexidine in oral care is a protective factor against VAP. Tooth brushing did not prevent VAP. More RCTs using this intervention are needed to confirm these results.

Abstract
Background Traumatic brain injury (TBI) is a main cause of severe prolonged disability of young patients. Hospital acquired pneumonia (HAP) add to the morbidity and mortality of traumatic brain-injured patients. In one study, hydrocortisone for treatment of traumatic-induced corticosteroid insufficiency (CI) in multiple injured patients has prevented HAP, particularly in the sub-group of patients with severe TBI. Fludrocortisone is recommended in severe brain-injured patients suffering from acute subarachnoid hemorrhage. Whether an association of hydrocortisone with fludrocortisone protects from HAP and improves neurological recovery is uncertain. The aim of the current study is to compare corticotherapy to placebo for TBI patients with CI. Methods The CORTI-TC (Corticotherapy in traumatic brain-injured patients) trial is a multicenter, randomized, placebo controlled, double-blind, two-arms study. Three hundred and seventy six patients hospitalized in Intensive Care Unit with a severe traumatic brain injury (Glasgow Coma Scale ≤ 8) are randomized in the first 24 hours following trauma to hydrocortisone (200 mg.day-1 for 7 days, 100 mg on days 8-9 and 50 mg on day-10) with fludrocortisone (50 μg for 10 days) or double placebo. The treatment is stopped if patients have an appropriate adrenal response. The primary endpoint is HAP on day-28. The endpoint of the ancillary study is the neurological status on 6 and 12 months. Discussion The CORTI-TC trial is the first randomized controlled trial powered to investigate whether hydrocortisone with fludrocortisone in TBI patients with CI prevent HAP and improve long term recovery.

Abstract
PURPOSE Povidone-iodine (polyvinylpyrrolidone iodine, PI), which is commonly used as a pre- and postoperative oral antiseptic, has been reported to cause pneumonia secondary to its pulmonary aspiration. Because no studies have yet investigated the underlying mechanisms of PI-induced pneumonia, we conducted an animal study to analyze the effect of PI on the lung following its pulmonary instillation. METHODS The lungs of 61 male Sprague-Dawley rats (150-250 g) were instilled with varying volumes of either phosphate-buffered saline or PI solutions varying in strength from 0.01% to 10%. The lungs were harvested from the rats 1 h or 1, 3, 5, 7, 14, or 21 days after instillation for radiologic examination, macroscopic and light and scanning electron microscopic assessment, and an assessment of pulmonary toxicity using an MTT-based cytotoxicity assay. RESULTS Macroscopically, atelectasis was the primary pulmonary lesion after PI instillation. The primary light and scanning electron microscopic findings were an initial inflammatory phase with edema, alveolar rupture, and leukocyte infiltration into the pulmonary interstitium, which progressed into a phase of lung parenchyma loss, and then resolved itself with scar tissue formation. Lung tissue viability following 1-day exposure to 0.01%, 0.1%, 1%, or 5% PI progressively decreased in a significant dose-dependent manner. CONCLUSIONS PI aspiration can cause lung injury, including pulmonary fibrosis.

Abstract
BACKGROUND We did a systematic review and random effects meta-analysis of randomised trials to assess the effect of oral care with chlorhexidine or povidone-iodine on the prevalence of ventilator-associated pneumonia versus oral care without these antiseptics in adults. METHODS Studies were identified through PubMed, CINAHL, Web of Science, CENTRAL, and complementary manual searches. Eligible studies were randomised trials of mechanically ventilated adult patients receiving oral care with chlorhexidine or povidone-iodine. Relative risks (RR) and 95% CIs were calculated with the Mantel-Haenszel model and heterogeneity was assessed with the I(2) test. FINDINGS 14 studies were included (2481 patients), 12 investigating the effect of chlorhexidine (2341 patients) and two of povidone-iodine (140 patients). Overall, antiseptic use resulted in a significant risk reduction of ventilator-associated pneumonia (RR 0.67; 95% CI 0.50-0.88; p=0.004). Chlorhexidine application was shown to be effective (RR 0.72; 95% CI 0.55-0.94; p=0.02), whereas the effect resulting from povidone-iodine remains unclear (RR 0.39; 95% CI 0.11-1.36; p=0.14). Heterogeneity was moderate (I(2)=29%; p=0.16) for the trials using chlorhexidine and high (I(2)=67%; p=0.08) for those assessing povidone-iodine use. Favourable effects were more pronounced in subgroup analyses for 2% chlorhexidine (RR 0.53, 95% CI 0.31-0.91), and in cardiosurgical studies (RR 0.41, 95% CI 0.17-0.98). INTERPRETATION This analysis showed a beneficial effect of oral antiseptic use in prevention of ventilator-associated pneumonia. Clinicians should take these findings into account when providing oral care to intubated patients. FUNDING None.

Prevention of ventilator-associated pneumonia, mortality and all intensive care unit acquired infections by topically applied antimicrobial or antiseptic agents: a meta-analysis of randomized controlled trials in intensive care units. CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2011; 15:R155. [PMID: 21702946 PMCID: PMC3219029 DOI: 10.1186/cc10285] [Citation(s) in RCA: 67] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/04/2011] [Revised: 04/27/2011] [Accepted: 06/24/2011] [Indexed: 01/07/2023]
Abstract
INTRODUCTION Given the high morbidity and mortality attributable to ventilator-associated pneumonia (VAP) in intensive care unit (ICU) patients, prevention plays a key role in the management of patients undergoing mechanical ventilation. One of the candidate preventive interventions is the selective decontamination of the digestive or respiratory tract (SDRD) by topical antiseptic or antimicrobial agents. We performed a meta-analysis to investigate the effect of topical digestive or respiratory tract decontamination with antiseptics or antibiotics in the prevention of VAP, of mortality and of all ICU-acquired infections in mechanically ventilated ICU patients. METHODS A meta-analysis of randomised controlled trials was performed. The U.S. National Library of Medicine's MEDLINE database, Embase, and Cochrane Library computerized bibliographic databases, and reference lists of selected studies were used. Selection criteria for inclusion were: randomised controlled trials (RCTs); primary studies; examining the reduction of VAP and/or mortality and/or all ICU-acquired infections in ICU patients by prophylactic use of one or more of following topical treatments: 1) oropharyngeal decontamination using antiseptics or antibiotics, 2) gastrointestinal tract decontamination using antibiotics, 3) oropharyngeal plus gastrointestinal tract decontamination using antibiotics and 4) respiratory tract decontamination using antibiotics; reported enough data to estimate the odds ratio (OR) or risk ratio (RR) and their variance; English language; published through June 2010. RESULTS A total of 28 articles met all inclusion criteria and were included in the meta-analysis. The overall estimate of efficacy of topical SDRD in the prevention of VAP was 27% (95% CI of efficacy = 16% to 37%) for antiseptics and 36% (95% CI of efficacy = 18% to 50%) for antibiotics, whereas in none of the meta-analyses conducted on mortality was a significant effect found. The effect of topical SDRD in the prevention of all ICU-acquired infections was statistically significant (efficacy = 29%; 95% CI of efficacy = 14% to 41%) for antibiotics whereas the use of antiseptics did not show a significant beneficial effect. CONCLUSIONS Topical SDRD using antiseptics or antimicrobial agents is effective in reducing the frequency of VAP in ICU. Unlike antiseptics, the use of topical antibiotics seems to be effective also in preventing all ICU-acquired infections, while the effectiveness on mortality of these two approaches needs to be investigated in further research.

Abstract
Ventilator-associated pneumonia (VAP) remains a significant problem in the hospital setting, with very high morbidity, mortality, and cost. We performed an evidence-based review of the literature focusing on clinically relevant pharmacological and nonpharmacological interventions to prevent VAP. Owing to the importance of this condition the implementation of preventive measures is paramount in the care of mechanically ventilated patients. There is evidence that these measures decrease the incidence of VAP and improve outcomes in the intensive care unit. A multidisciplinary approach, continued education, and ventilator protocols ensure the implementation of these measures. Future research will continue to investigate cost/benefit relationships, antibiotic resistance, as well as newer technologies to prevent contamination and aspiration in mechanically ventilated patients.

Abstract
Over the last 5 y, clinical trials investigating products, procedures, and treatments aimed at preventing infections in the intensive care unit have been described. The findings of these studies appear to confirm the effectiveness of certain preventive procedures. With regard to ventilator-associated pneumonia, the efficacies of decontamination of the oral cavity, continuous suction of subglottic secretions, positioning of the patient, selective decontamination of the digestive tract, and (for higher-risk patients) endotracheal tubes coated with silver, have been demonstrated. Medicated catheters and chlorhexidine-based dressings have been found useful for catheter-related bloodstream infections, and medical catheters have also been shown to be efficacious against urinary tract infections. All these procedures can be incorporated into departmental protocols for the prevention of nosocomial infections in the intensive care unit.

Abstract
Ventilator-associated pneumonia (VAP) affects 10-20% of mechanically ventilated patients and is associated with increased morbidity and mortality and high costs. Early diagnosis is crucial for rapid appropriate antimicrobial therapy to be instituted, but debate remains as to the optimal diagnostic strategy. Noninvasive clinical-based diagnosis is rapid but may not be as accurate as invasive techniques. Increased use of biomarkers and advances in genomics and proteomics may help speed up diagnosis. Management of VAP relies principally on appropriate antimicrobial therapy, which should be selected according to individual patient factors, such as previous antibacterial therapy and length of hospitalization or mechanical ventilation, and local infection and resistance patterns. In addition, once bacterial culture and sensitivity results are available, broad-spectrum therapy should be de-escalated to provide a more specific, narrower-spectrum cover. Optimum duration of antibacterial therapy is difficult to define and should be tailored to clinical response. Biomarker levels may be useful to monitor response to therapy. With the high morbidity and mortality, prevention of VAP is important and several strategies have been shown to reduce the rates of VAP in mechanically ventilated patients, including using noninvasive ventilation where possible, and semi-recumbent positioning. Other potentially beneficial preventive techniques include subglottal suctioning, oral decontamination strategies and antimicrobial-coated endotracheal tubes, although further study is needed to confirm the cost effectiveness of these strategies.

Effects of three approaches to standardized oral hygiene to reduce bacterial colonization and ventilator associated pneumonia in mechanically ventilated patients: a randomised control trial. Int J Nurs Stud 2010; 48:681-8.

Abstract
BACKGROUND Ventilator associated pneumonia remains an important concern in the intensive care unit (ICU). An increasing body of evidence shows that mortality and morbidity can be reduced by implementing a range of preventive strategies, including optimizing oral hygiene. AIM The aim of this feasibility study was to test two oral hygiene strategies on the effects of microbial colonization of dental plaque with respiratory pathogens (primary outcome) and incidence of ventilator associated pneumonia (secondary outcome). METHODS A single blind randomised comparative study was conducted in a 20-bed adult intensive care unit in a university hospital. Patients with an expected duration of mechanical ventilation more than 48 h were eligible. Patients were randomised to one of three study regimens (Group A control, second hourly oral rinse with sterile water, Group B sodium bicarbonate mouth wash second hourly, and Group C twice daily irrigations with chlorhexidine 0.2% aqueous oral rinse and second hourly irrigations with sterile water). All study options included cleaning with a toothbrush and non foaming toothpaste. RESULTS Data from a total of 109 patients were analyzed. Group A 43, Group B 33 and Group C 33 (mean age: 58 ± 17 years, simplified acute physiology score II: 44 ± 14 points). On admission no significant differences were found between groups for all clinical data. While Group B showed a greater trend to reduction in bacterial colonization no significant differences could be demonstrated at Day 4 of admission (p=0.302). The incidence of ventilator associated pneumonia was evenly spread between Groups B and C (5%) while Group A was only 1%. CONCLUSIONS While a number of studies have advocated the use of various mouth rinses in reducing colonization of dental plaque a standardized oral hygiene protocol which includes the use of mechanical cleaning with a toothbrush may be a factor in the reduction of colonization of dental plaque with respiratory pathogens. This feasibility study provides data to inform future adequately powered studies.

Abstract
The nasal septoplasty is a very current intervention in otorhinolaryngology surgery. The infectious complications of this intervention are rare and mostly mild. We report here the case of a patient hospitalized in ambulatory surgery within a fracture of the nose with luxation of the septum in the nasal fossa. This patient was operated for a reduction of this fracture with septoplasty. Twelve hours after the intervention the patient presented septic arthritis due to Streptococcus pyogenes. The tracks of prevention are presented.
