Update on etiology, prevention, and management. As acknowledged by the authors, the single-center design and inclusion of only subjects after major vascular surgery preclude definite conclusions.
Shin et al 57 showed that in anesthetized subjects receiving N2O, Pcuff was significantly lower in subjects with tapered-cuff compared with those with standard-cuff tracheal tubes. Further large multi-center studies are required to confirm the impact of continuous control of Pcuff on VAP rate and to evaluate its cost-effectiveness.
Nine patients required mechanical ventilation for less than 48 h, 6 in the control group and 3 in the SSD group, and they were excluded because of the unavailability of complete data. Currently, SSD by using inspiratory pause maneuver is Effect of oropharyngeal secretion and subglottic investigational intervention, and further research with a larger sample size is needed to prove its effects.
Sub-glottic secretions accumulated above the endotracheal cuff may progress, descending along the channels within the folds of the cuff wall, into the lower respiratory tract.
CT imaging showed marked entrapment of tracheal mucosa into the suction port in all patients. There were 53 male Knowledge of the volume of secretions that accumulates over time may help to determine a recommended frequency for oropharyngeal suctioning.
Among the remaining patients, met the exclusion criteria. Because of the nature of the intervention, physicians and nurses could not be blinded to the randomisation arm. The 5 patients who required extra suctioning had significantly more secretions at the 2-hour interval The number of patients needed to treat to prevent one VAP episode was 8.
Polyurethane and PEEP both significantly protected subjects from aspiration of blue dye. Curr Infect Dis Rep. Two other randomized controlled trials reported reduced incidence of VAP in subjects intubated with polyurethane-cuffed tracheal tubes compared with PVC-cuffed tracheal tubes.
A systematic review and meta-analysis. In addition, this technique is applicable in all intubated patients, as it was tolerated by all patients in the intervention group and no adverse effect was found.
Several factors might explain the different results of these trials, including the difference in devices used for Pcuff control, study population, and VAP rate in the control group. Ina quasi-randomized controlled study was conducted to determine the impact of continuous control of Pcuff, using an electronic device, on VAP incidence in critically ill subjects.
A more recent meta-analysis, 12 including 3 additional randomized controlled trials with 3, subjects, reported similar results on efficiency. The effects of an oral care practice on incidence of pneumonia among ventilator patients in ICUs of selected hospitals in Isfahan, By reducing the volume of secretions in the mouth, oral suctioning is an important early step in reducing the risk of aspiration of secretions.
Tapered-cuff tracheal tubes are not useful to prevent VAP and should probably not be used in critically ill patients. Iran J Nurs Midwifery Res. The 5 patients who required extra suctioning had significantly more secretions at the 2-hour interval Routine suctioning of oropharyngeal secretions may reduce this risk; the recommended frequency for suctioning is unknown.
Routine oropharyngeal suctioning may reduce the likelihood of accumulation of secretions above the cuff of the endotracheal tube, where aspiration often occurs. However, no significant difference was found in other secondary outcomes, including abundant microaspiration of oropharyngeal secretions, ventilator-associated events, and VAP, between the 2 groups.
Subglottic secretion drainage for the prevention of ventilator-associated pneumonia: However, the single-center design and the very short duration of mechanical ventilation in study subjects 15 h vs 13 h in the PneuX and standard tube groups, respectively preclude any definite conclusions regarding the effectiveness of using the PneuX tube for VAP prevention.
The incidence of early-onset VAP in the case and control groups was the outcome measure and was compared between them. Polyurethane-Cuffed Tracheal Tubes Polyurethane is fold thinner than polyvinyl chloride PVCresulting in reduced channel formation between the tracheal cuff and the tracheal wall.
Studies 6 — 8 have shown that when oral suction was part of a comprehensive oral care program, rates of ventilator-associated pneumonia decreased. Using Monte Carlo simulations and sensitivity analyses, Shorr et al 64 reported that estimates were most sensitive to assumptions regarding VAP cost and relative risk reduction with silver-coated endotracheal tubes, compared with standard tubes.
Non-pharmacological prevention of ventilator associated pneumonia. Five patients required suctioning before the 4-hour interval.
First, a large proportion of study subjects received antibiotic treatment during their ICU stay, which might have been a confounder regarding the results on colonization rate.
The mean volume of secretions at the 2-hour interval was 7. Second, tracheobronchial colonization is probably not an excellent marker for microaspiration, because it could also result from exogenous contamination.
Sub-glottic suctioning was not performed in the Group II.Comparison of Two Strategies of Oropharyngeal and Tracheal Suctioning in Mechanically Ventilated Patients (AMYLASPI) The safety and scientific validity of this study is the responsibility of the study sponsor and investigators.
Secretions contaminated with oral, nasal, and gastric bacteria accumulate in the subglottic space, above the endotracheal tube cuff. If these secretions are aspirated into lower airways, the intubated patient will be susceptible to ventilator-associated pneumonia (VAP).
Background Aspiration of secretions that accumulate above the cuff of the endotracheal tube is a risk factor for ventilator-associated pneumonia. Routine suctioning of oropharyngeal secretions may reduce this risk; the recommended frequency for suctioning is unknown.
Objectives To quantify the. subglottic secretions toward the oropharynx from where they (secretions) were removed with repeated oropharyngeal suctioning by a nurse specialist in critical care.
Microaspiration of contaminated oropharyngeal and gastric secretions is the main mechanism for ventilator-associated pneumonia (VAP) in critically ill patients. Improving the performance of tracheal tubes in reducing microaspiration is one potential means to prevent VAP.
