Abstract
Objectives To investigate the epidemiology of MDR Gram-negative bacilli ventilator-associated tracheobronchitis (MDR GNB-VAT) and MDR GNB ventilator-associated pneumonia (MDR GNB-VAP) among mechanically ventilated patients. Methods We conducted a retrospective observational study among hospitalized patients who underwent continuous mechanical ventilation for ≥48 h at Siriraj Hospital, Thailand. Results During the 18 month study period, 1824 unique patients underwent continuous mechanical ventilation (12 216 ventilator-days). The cumulative incidences of MDR GNB-VAT and -VAP were 8.4% and 8.3%, respectively. The incidence rates of MDR GNB-VAT and -VAP were 12.52 and 12.44 episodes/1000 ventilator-days, respectively. Among those with VAT, the cumulative incidence and incidence rate of subsequent VAP development within 7 days were 11.76% and 2.81 episodes/1000 ventilator-days, respectively. The median durations of mechanical ventilation before having VAP and VAT were 9 and 12 days, respectively. Multivariate analysis identified three independently associated factors for patients having VAP compared with having VAT: underlying cerebrovascular disease [adjusted OR (aOR): 0.46; 95% CI: 0.27-0.78; P = 0.04], previous surgery (aOR: 0.68; 95% CI: 0.57-0.8; P < 0.001) and acute renal failure (aOR: 1.75; 95% CI: 1.27-2.40; P = 0.001). Conclusions The study revealed high incidences of MDR GNB-VAT and -VAP among mechanically ventilated patients. The independent risk factors for having VAP can help identify patients at risk for developing VAP and who need early weaning from mechanical ventilation.

Abstract
The second most prevalent healthcare-associated infection in neonatal intensive care units (NICUs) is ventilator-associated pneumonia (VAP). This review aims to update the knowledge regarding the incidence of neonatal VAP and to summarize possible strategies for prevention. The VAP incidence ranges from 1.4 to 7 episodes per 1000 ventilator days in developed countries and from 16.1 to 89 episodes per 1000 ventilator days in developing countries. This nosocomial infection is linked to higher rates of illness, death, and longer hospital stays, which imposes a substantial financial burden on both the healthcare system and families. Due to the complex nature of the pathophysiology of VAP, various approaches for its prevention in the neonatal intensive care unit have been suggested. There are two main categories of preventative measures: those that attempt to reduce infections in general (such as decontamination and hand hygiene) and those that target VAP in particular (such as VAP care bundles, head of bed elevation, and early extubation). Some of the interventions, including practicing good hand hygiene and feeding regimens, are easy to implement and have a significant impact. One of the measures that seems very promising and encompasses a lot of the preventive measures for VAP are the bundles. Some preventive measures still need to be studied.

Abstract
OBJECTIVE To characterize the oral and tracheal microbiota of patients admitted to a pediatric intensive care unit (PICU). METHODS AND RESULTS This is an exploratory study conducted on patients aged 5 months to 13 years admitted to the PICU of a referral hospital. Two microbiological samples were collected with a swab in the posterior region of the tongue from patients receiving spontaneous and mechanical ventilation within the first 24 and 48 h after admission to the PICU. Among patients receiving mechanical ventilation, tracheal secretion was also collected in a second sampling. The caries experience was evaluated using the DMFT/dmf index, and the quality of oral hygiene was assessed based on the visual plaque index (VPI). A questionnaire was applied to obtain data on hospital routine and sample characteristics. The DMFT/dmf index was 1.66 (SD = 2.18) and the mean VPI was 43.03 (SD = 36.93). The most prevalent microorganisms were Klebsiella pneumoniae (15%). Oral colonization by opportunistic pathogens was significantly higher in patients receiving mechanical ventilation compared to those on spontaneous ventilation (p < .05). There was no relationship of VPI or DMFT/dmf with oral microbiological changes. CONCLUSION The results indicate that PICU patients are susceptible to colonization by respiratory and opportunistic pathogens since the first hours of hospitalization.

Abstract
Objective This a cross-sectional study to evaluate the association between oral health findings and ventilator-associated pneumonia (VAP) among critically ill patients in intensive care units (ICU). Material and methods Data were collected from medical records, and a detailed oral physical examination was performed on 663 critically ill patients on mechanical ventilation. Data were statistically analysed using univariate and logistic regression models relating the development of VAP with the oral findings. Results At oral physical examination, the most frequent findings were tooth loss (568–85.67%), coated tongue (422–63.65%) and oral bleeding (192–28.96%). Patients with a coated tongue or oral bleeding on the first day of ICU hospitalization developed more VAP than did patients without these conditions (20.14 vs 13.69%, p = 0.02; 23.44 vs 15.50%, p = 0.01, respectively). In the logistic regression, a coated tongue and oral bleeding were considered independent risk factors for VAP development (OR = 1.61 (1.03–2.51) and OR = 1.69 (1.08–2.66), respectively). Conclusions The presence of a coated tongue and oral bleeding in ICU admission could be considered markers for the development of VAP. Clinical relevance The results of this paper reinforce the importance of proper maintenance of oral hygiene before intubation, which may lead to a decrease in the incidence of VAP in the ICU.

Abstract
Objective To assess the effects of two different nutritional mode on the occurrence of ventilator-associated pneumonia (VAP) in patients on mechanical ventilation. Methods 70 patients admitted to the ICU and under mechanical ventilation, were randomly divided into the nasointestinal tube group and nasogastric tube group. Patients from both groups received enteral nutrition, using the same nutritional agent, through intubation. The duration of stay in the ICU, duration of mechanical ventilation, incidence of VAP, nutritional state, and survival of the intestinal tract were compared between the two groups. Results The duration of stay in the ICU, duration of mechanical ventilation and incidence of VAP in the nasointestinal tube group was lower than that in the nasogastric tube group (P<0.05). There was an increase in the levels of prealbumin and transferrin in the nasointestinal tube group (P<0.05). However, there were no obvious difference in the nasogastric tube group (P<0.05). The incidence of abdominal distension, diarrhea, regurgitation, aspiration, and hyperglycemia in the nasointestinal tube group was much lower than that in the nasogastric tube group (P < 0.05). Conclusion This study showed that enteral nutrition delivery using a nasointestinal way can effectively reduce the incidence of VAP and improve the nutritional status of patients under mechanical ventilation.

Abstract
OBJECTIVES Ventilator-associated pneumonia is the second most common nosocomial infection in pediatric intensive care. The Centers for Disease Control and Prevention recently issued diagnosis criteria for pediatric ventilator-associated pneumonia and for ventilator-associated events in adults. The objectives of this pediatric study were to determine the prevalence of ventilator-associated pneumonia using these new Centers for Disease Control and Prevention criteria, to describe the risk factors and management of ventilator-associated pneumonia, and to assess a simpler method to detect ventilator-associated pneumonia with ventilator-associated event in critically ill children. DESIGN Retrospective, observational, single-center. SETTING PICU in a tertiary-care university hospital. PATIENTS Consecutive critically ill children mechanically ventilated for greater than or equal to 48 hours between November 2013 and November 2015. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Of 304 patients mechanically ventilated for greater than or equal to 48 hours, 284 were included. Among them, 30 (10.6%) met clinical and radiologic Centers for Disease Control and Prevention criteria for ventilator-associated pneumonia, yielding an prevalence of 7/1,000 mechanical ventilation days. Median time from mechanical ventilation onset to ventilator-associated pneumonia diagnosis was 4 days. Semiquantitative culture of tracheal aspirates was the most common microbiological technique. Gram-negative bacteria were found in 60% of patients, with a predominance of Haemophilus influenzae and Pseudomonas aeruginosa. Antibiotic therapy complied with adult guidelines. Compared with patients without ventilator-associated pneumonia, those with ventilator-associated pneumonia had significantly longer median durations of mechanical ventilation (15 vs 6 d; p < 0.001) and PICU stay (19 vs 9 d; p < 0.001). By univariate analysis, risk factors for ventilator-associated pneumonia were younger age, reintubation, acute respiratory distress syndrome, and continuous enteral feeding. Among the 30 patients with ventilator-associated pneumonia, 17 met adult ventilator-associated event's criteria (sensitivity, 56%). CONCLUSIONS Ventilator-associated pneumonia is associated with longer times on mechanical ventilation and in the PICU. Using the ventilator-associated event criteria is of interest to rapidly screen for ventilator-associated pneumonia in children. However, sensitivity must be improved by adapting these criteria to children.

Abstract
Mechanical ventilation is a lifesaving treatment and has complications such as ventilator associated pneumonia (VAP) that lead to high morbidity and mortality. Moreover VAP is the second most common hospital-acquired infection in pediatric intensive care units. Although it is still not well understood, understanding molecular pathogenesis is essential for preventing and treating pneumonia. A lot of microbes are detected as a causative agent of VAP. The most common isolated VAP pathogens in pediatric patients are Staphylococcus aureus, Pseudomonas aeruginosa, and other gram negative bacteria. All of the bacteria have different pathogenesis due to their different virulence factors and host reactions. This review article focused on mechanisms of VAP with molecular pathogenesis of the causative bacteria one by one from the literature. We hope that we know more about molecular pathogenesis of VAP and we can investigate and focus on the management of the disease in near future.

Abstract
BACKGROUND Ventilator-associated pneumonia (VAP) in neonates can be reduced by implementing preventive care practices. Implementation of a group, or bundle, of evidence-based practices that improve processes of care has been shown to be cost-effective and to have better outcomes than implementation of individual single practices. PURPOSE The purpose of this article is to describe a safe, effective, and efficient neonatal VAP prevention protocol developed for caregivers in the neonatal intensive care unit (NICU). Improved understanding of VAP causes, effects of care practices, and rationale for interventions can help reduce VAP risk to neonatal patients. METHOD In order to improve care practices to affect VAP rates, initial and annual education occurred on improved protocol components after surveying staff practices and auditing documentation compliance. FINDINGS/RESULTS In 2009, a tertiary care level III NICU in the Midwestern United States had 14 VAP cases. Lacking evidence-based VAP prevention practices for neonates, effective adult strategies were modified to meet the complex needs of the ventilated neonate. A protocol was developed over time and resulted in an annual decrease in VAP until rates were zero for 20 consecutive months from October 2012 to May 2014. IMPLICATIONS FOR PRACTICE This article describes a VAP prevention protocol developed to address care practices surrounding hand hygiene, intubation, feeding, suctioning, positioning, oral care, and respiratory equipment in the NICU. IMPLICATIONS FOR RESEARCH Implementation of this VAP prevention protocol in other facilities with appropriate monitoring and tracking would provide broader support for standardization of care. Individual components of this VAP protocol could be studied to strengthen the inclusion of each; however, bundled interventions are often considered stronger when implemented as a whole.

Exposure to reprocessed single-use tracheal suction catheter and ventilator-associated pneumonia risk: A preliminary, single unit-based, matched case-control study. J Crit Care 2016; 32:145-51. [PMID: 26775186 DOI: 10.1016/j.jcrc.2015.11.018] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2015] [Revised: 10/27/2015] [Accepted: 11/19/2015] [Indexed: 10/22/2022]
Abstract
PURPOSE The reuse of reprocessed single-use suction catheter for suctioning an amount of tracheal secretion among orally intubated, mechanically ventilated patients, who are at risk of acquiring ventilator-associated pneumonia (VAP), has not been thoroughly investigated. This study aimed to examine the association between the repetitive use of reprocessed single-use suction catheter and VAP development. MATERIALS AND METHODS A preliminary, single unit-based investigation was designed as matched case-control study to extract data from hospital's existing 5-year VAP report and inpatients' clinical records. Cases were defined as patients, who developed VAP between December 2009 and October 2014. Controls were defined as patients, who had no evidence of VAP during study period. Six hundred eight controls were frequency matched to 152 cases in 4:1 ratio. Chart-extracted clinical data were stratified and included for conditional logistic regression analysis. RESULTS Analysis showed a significant association between reprocessed single-use tracheal suction catheter exposure and VAP development [odds ratio (OR), 3.64; 95% confidence interval (CI), 2.47-5.35]. A statistically significant increase in VAP risk was found in male intubated patients (OR, 5.33; 95% CI, 1.22-23.3), who are older than 60 years (OR, 8.08; 95% CI, 1.47-44.3), had severe Glasgow Coma Scale scores (OR, 8.27; 95% CI, 1.83-37.3), and received mechanical ventilatory support for more than 96 hours (OR, 9.67; 95% CI, 1.98-47.1). In addition, a statistically significant increase in VAP risk was seen in intensive care unit, where reprocessed tracheal suction catheter changes were routinely provided (OR, 16.0; 95% CI, 2.40-106.7) and unsatisfactory hand hygiene percentage compliance was observed (OR, 8.40; 95% CI, 1.60-44.1). Ventilator-associated pneumonia proportion analysis revealed a higher number of unknown exogenous VAP among exposed cases compared to nonexposed case patients (32.2% vs 13.8%; OR, 2.31; 95% CI, 1.31-4.05; P < .005) that were mechanically ventilated for more than 96 hours (62.5% vs 25.7%; OR, 3.62; 95% CI, 2.40-5.46; P < .0001). CONCLUSIONS This current study suggests that exposure to reprocessed single-use tracheal suction catheter may predispose orally intubated, mechanically ventilated patients in developing VAP. Further research studies are recommended to validate these findings. IMPLICATIONS FOR CLINICAL NURSING PRACTICE The estimated VAP risk of this traditional-based practice is essential to provide strong basis for infection control measures to reduce, if not totally eliminate, VAP.

Abstract
The intensive care unit is a work environment where superior dedication is crucial for optimizing patients' outcomes. As this demanding commitment is multidisciplinary in nature, it requires special qualities of health care workers and organizations. Thus research in the field covers a broad spectrum of activities necessary to deliver cutting-edge care. However, given the numerous research articles and education activities available, it is difficult for modern critical care clinicians to keep up with the latest progress and innovation in the field. This article broadly summarizes new developments in multidisciplinary intensive care. It provides elementary information about advanced insights in the field via brief descriptions of selected articles grouped by specific topics. Issues considered include care for heart patients, mechanical ventilation, delirium, nutrition, pressure ulcers, early mobility, infection prevention, transplantation and organ donation, care for caregivers, and family matters.
