Management of Aspiration and Aspiration Pneumonia in CVICU

Prevention Strategies

The American College of Cardiology recommends maintaining patients in semi-recumbent position (30-45° head elevation) at all times, especially during enteral feeding, to prevent aspiration 1, 2
The American Thoracic Society suggests using orotracheal rather than nasotracheal intubation to reduce the risk of nosocomial sinusitis and subsequent pneumonia 3, 1
The Infectious Diseases Society of America recommends maintaining endotracheal tube cuff pressure above 20 cm H2O to prevent leakage of oropharyngeal contents into the lower respiratory tract 3, 4
The Society of Critical Care Medicine suggests considering endotracheal tubes with subglottic secretion drainage capability for continuous or frequent intermittent suctioning of tracheal secretions 1, 5

The American Thoracic Society recommends using noninvasive ventilation (NIV) when appropriate to reduce the need for endotracheal intubation 3, 6
The American College of Chest Physicians suggests avoiding reintubation whenever possible as it significantly increases aspiration risk 3, 1
The Society of Critical Care Medicine recommends implementing weaning protocols to reduce duration of mechanical ventilation 4
The American Thoracic Society suggests minimizing sedation through protocol-guided administration and daily interruption to reduce ventilator days 4

The American Gastroenterological Association recommends verifying appropriate placement of feeding tubes before initiating feeds 1
The Society of Critical Care Medicine suggests avoiding gastric overdistention during enteral feeding 4
The American Thoracic Society recommends draining ventilator tube condensate carefully to prevent accidental aspiration 3, 4

The American College of Radiology recommends using chest radiography to identify new infiltrates 7
The American Institute of Ultrasound in Medicine suggests considering thoracic CT or ultrasound when radiographic findings are equivocal 6
The Infectious Diseases Society of America recommends obtaining lower respiratory tract samples for Gram stain and culture before initiating antibiotics 7
The American Thoracic Society suggests evaluating Clinical Pulmonary Infection Score (CPIS) on initial assessment and at day 3 5, 7

The Infectious Diseases Society of America recommends initiating prompt empiric antibiotic therapy when aspiration pneumonia is suspected 7
The American Thoracic Society suggests basing antibiotic selection on time of onset, risk factors for multidrug-resistant (MDR) pathogens, and local pathogen epidemiology and resistance patterns 6, 7
The Society of Critical Care Medicine recommends de-escalating antibiotics based on culture results and clinical response 5, 7
The American College of Chest Physicians suggests treating for 7 days if good clinical response and no complications 5, 7

The American Diabetes Association recommends maintaining glycemic control as hyperglycemia increases aspiration risk 3
The American Thoracic Society suggests considering the impact of blood transfusions, as they may increase pneumonia risk in critically ill patients 3

The Infectious Diseases Society of America recommends avoiding treating aspiration pneumonitis with antibiotics (not indicated and contributes to antimicrobial resistance)
The American Thoracic Society suggests not delaying appropriate antibiotic therapy for true aspiration pneumonia, which increases mortality 7
The Society of Critical Care Medicine recommends not failing to de-escalate antibiotics once culture results are available 7
The American College of Chest Physicians suggests not using prolonged courses of antibiotics when shorter durations would be sufficient 5, 7
The American Thoracic Society recommends not neglecting to maintain head elevation at 30-45° (compliance with this simple intervention is often poor) 4
