BACKGROUND: Despite intermittent control of tracheal cuff pressure (P cuff) using a manual manometer, cuff underinflation (<20 cmH2O) and overinflation (>30 cmH2O) frequently occur in intubated critically ill patients, resulting in increased risk of microaspiration and tracheal ischemic lesions. The primary objective of our study was to determine the efficiency of an electronic device in continuously controlling P cuff. The secondary objective was to determine the impact of this device on the occurrence of microaspiration of gastric or oropharyngeal secretions...

INTRODUCTION: Patients at risk for microaspiration during elective intubation often receive cricoid pressure in the hopes of mitigating such risk. However, there is scarce evidence to either support or reject this practice. The objective of this investigation was to assess the effect of cricoid pressure on microaspiration and to inform the potential feasibility of conducting a larger, more definitive clinical trial. METHODS: This was a pilot randomized clinical trial set in the operating rooms of a tertiary referral hospital between August and October of 2014...

BACKGROUND: Patients undergoing major vascular surgery often develop postoperative pneumonia that impacts their outcomes. Conflicting data exist concerning the potential benefit of tapered-shaped cuffs on tracheal sealing. The primary objective of this study was to assess the efficiency of a polyvinyl chloride tapered-cuff endotracheal tube at reducing the postoperative pneumonia rate after major vascular surgery. Secondary objectives were to determine its impact on microaspiration, ventilator-associated pneumonia rate, and inner cuff pressure...

OBJECTIVES: Gastroesophageal reflux is common but remains a controversial disease to diagnose and treat and little is known about the role of reflux testing in predicting clinical outcomes, particularly in children at risk for extraesophageal reflux complications. The aim of this study was to determine if rates of hospitalization were affected by reflux burden even after adjusting for aspiration risk. METHODS: We prospectively recruited, between 2009 and 2014, a cohort of pediatric patients with suspected extraesophageal reflux disease who were referred for reflux testing and underwent both multichannel intraluminal impedance with pH (pH-MII) and modified barium swallow studies...

BACKGROUND: Ventilator-associated pneumonia (VAP) is the most common infection in intubated critically ill patients. Microaspiration of the contaminated gastric and oropharyngeal secretions is the main mechanism involved in the pathophysiology of VAP. Tracheal cuff plays an important role in stopping the progression of contaminated secretions into the lower respiratory tract. Previous in vitro studies suggested that conical cuff shape might be helpful in improving tracheal sealing. However, clinical studies found conflicting results...

Gastroesophageal reflux (GER) can cause respiratory symptoms and may trigger, drive and/or worsen airway disorders, interstitial lung diseases and lung allograft dysfunction. Whether lifestyle changes and acid suppression alone can counter and prevent the adverse effects of GER on the respiratory tract remains unclear. Recent data suggest that antireflux surgery may be more effective in preventing lung disease progression in patients with idiopathic pulmonary fibrosis or lung transplant recipients who have evidence of allograft dysfunction associated with the presence of excessive GER...

BACKGROUND: Withholding enteral feedings during repositioning is based on tradition, but available evidence does not support this practice. Although research indicates that withholding of enteral feedings during repositioning contributes to undernourishment, the relationship between continuing enteral feedings during repositioning and the incidence of aspiration has not been determined. OBJECTIVE: To determine the feasibility of a study designed to explore differences in the incidence of aspiration when enteral feedings are withheld or continued during repositioning...

The objective of the present experimental study was to develop the qualitatively new method for the determination of stomach contents left on the material objects and in the environment with special reference to the cases of aspiration asphyxia. We proposed the original approach for the determination of the origin of the traces of stomach contents based on the detection of pepsin, an enzyme that digests in the acidic milieu protein substances, such as gelatin (hydrolyzed collagen), a component of the emulsion layer of X-ray and photographic films...

BACKGROUND: Gastroesophageal reflux (GER) and pulmonary aspiration are frequent in patients in the ICU. The presence of pepsin in airways seems to be the link between them. However, pepsin isoforms A (gastric specific) and C (pneumocyte potentially derived) need to be distinguished. This study aimed to evaluate GER patterns and to determine the presence of pepsin A and C in tracheal secretions of critically ill children receiving mechanical ventilation. METHODS: All patients underwent combined multichannel intraluminal impedance-pH (MII-pH) monitoring...

IMPORTANCE: Otitis media is characterized as an ongoing inflammation with accumulation of an effusion in the middle ear cleft. The molecular mechanisms underlying the pathogenesis, particularly the inflammatory response, remain largely unknown. We hypothesize that aspiration of gastric contents into the nasopharynx may be responsible for the initiation of the inflammatory process or aggravate a preexisting condition. OBJECTIVE: To investigate the correlation of gastric pepsin A with inflammatory cytokines, bacterial infection, and clinical outcomes...

BACKGROUND: Guidelines recommending head of bed (HOB) elevation greater than 30º to prevent ventilator-associated pneumonia conflict with guidelines to prevent pressure ulcers, which recommend HOB elevation less than 30º. OBJECTIVES: To examine the feasibility of 45º HOB elevation and describe and compare the occurrence of reflux, aspiration, and pressure ulcer development at 30º and 45º HOB elevation. METHODS: A randomized 2-day crossover trial was conducted...

Chronic inflammation induces lymphangiogenesis and blood vessel remodelling. Since aged pneumonia patients often have repeated episodes of aspiration pneumonia, the pathogenesis may involve chronic inflammation. For lymphangiogenesis, VEGFR-3 and its ligand VEGF-C are key factors. No previous studies have examined chronic inflammation or vascular changes in aspiration pneumonia or its mouse models. In lung inflammation, little is known about the effect of blocking VEGFR-3 on lung lymphangiogenesis and, moreover, its effect on the disease condition...

OBJECTIVES: To determine the frequency of tracheal pepsin in ventilated neonates and whether the angle of head elevation was associated with tracheal pepsin. STUDY DESIGN: Serial trachael samples (at 3, 7, 14, 21 and 28 days of ventilation) were obtained from intubated, ventilated very low birth weight infants. Presence of tracheal pepsin was determined by Western blot analysis using a specific anti-human pepsin antibody. RESULTS: Tracheal pepsin was detected in 35/66 (53%) of the ventilated neonates (birthweight: 798 ± 268 grams [mean ± standard deviation])...
