Evidence: Valles 1995 Setting: Medical-surgical ICU. Setting: Medical-surgical ICU. Patients: 190 admitted to ICU during a 33-month period and whose condition suggested the need for prolonged intubation (>3 days). Patients: 190 admitted to ICU during a 33-month period and whose condition suggested the need for prolonged intubation (>3 days). Intervention: 76 patients randomly allocated to receive CASS, 77 control patients allocated to usual care. Intervention: 76 patients randomly allocated to receive CASS, 77 control patients allocated to usual care. Results: CASS vs Controls Results: CASS vs Controls –19.9 vs 39.6 episodes/1000 ventilator days (relative risk, 1.98; 95% CI, ) –VAP occurred later in CASS pts /-7.1 days vs 5.9 +/-2.1 days (P = 0.003). –The same microorganisms isolated from protected specimen brush or bronchoalveolar lavage cultures in patients with VAP were previously isolated from cultures of subglottic secretions in 85% of cases. Conclusions: The incidence of nosocomial pneumonia in mechanically ventilated patients can be significantly reduced by using a simple method that decreases the chronic microaspirations through the cuff of ETTs. Conclusions: The incidence of nosocomial pneumonia in mechanically ventilated patients can be significantly reduced by using a simple method that decreases the chronic microaspirations through the cuff of ETTs.

5 studies, 896 patients. Subglottic secretion drainage reduced the incidence of VAP by nearly half (risk ratio [RR] 0.51; 95% CI 0.37 to 0.71), primarily by reducing early-onset pneumonia (pneumonia occurring within 5 to 7 days after intubation). CASS shortened – –duration of mechanical ventilation by 2 days (95% CI: days) – –ICU length of stay by 3 days (95% CI: 2.1 to 3.9 days) – –delayed the onset of pneumonia by 6.8 days (95% CI: 5.5 to 8.1 days).

Conclusion: Subglottic secretion drainage appears effective in preventing early-onset VAP among patients expected to require 72 hours of mechanical ventilation.

Precautions for Prevention of Aspiration 1. 1.Prevention of aspiration associated with endotracheal intubation a. a. Use of NIV to reduce the need for and duration of endotracheal intubation…CATEGORY II b. …avoid repeat endotracheal intubation…CATEGORY II c. …orotracheal rather than nasotracheal intubation …CATEGORY IB d. …use an ETT with a dorsal lumen above endotracheal cuff to allow drainage (by continuous or frequent intermittent suctioning) of tracheal secretions that accumulate in the patient's subglottic area... CATEGORY II e. Before …(extubation)…ensure that secretions are cleared from above the tube cuff. CATEGORY II

Major Points and Recommendations for Modifiable Risk Factors Intubation and mechanical ventilation. 1. Intubation and reintubation should be avoided, if possible, as it increases the risk of VAP (Level I) 2. Noninvasive ventilation should be used whenever possible in selected patients with respiratory failure (Level I) 3. Orotracheal intubation and orogastric tubes are preferred over nasotracheal intubation and nasogastric tubes to prevent nosocomial sinusitis and to reduce the risk of VAP, although direct causality has not been proved (Level II) Continuous aspiration of subglottic secretions can reduce the risk of early-onset VAP, and should be used (Level I) 4. Continuous aspiration of subglottic secretions can reduce the risk of early-onset VAP, and should be used (Level I) 5. The ETT cuff pressure should be maintained at > 20 cm H2O to prevent leakage of bacterial pathogens around the cuff into the lower respiratory tract (Level II) 6. Contaminated condensate should be carefully emptied from ventilator circuits and condensate should be prevented from entering either the endotracheal tube or inline medication nebulizers (Level II) 7. Passive humidifiers or HMEs decrease ventilator circuit colonization, but have not consistently reduced the incidence of VAP, and thus they cannot beregarded as a pneumonia prevention tool (Level I) 8. Reduced duration of intubation and mechanical ventilation may prevent VAP and can be achieved by protocols to improve the use of sedation and to accelerate weaning(Level II) 9. Maintaining adequate staffing levels in the ICU can reduce length of stay, improve infection control practices, and reduce duration of mechanical ventilation (Level II)

Purpose: To develop an evidence-based guideline for VAP prevention Subglottic Secretion Drainage On the basis of evidence from five level 2 trials, we conclude that subglottic secretion drainage is associated with decreased incidence of VAP, especially early onset VAP. Status: We recommend that clinicians consider the use of subglottic secretion drainage. Ann Intern Med. 2004;141:
