Importance, morbidity, and mortality of pneumonia in the surgical intensive care unit
1Department of Surgery, New York-Presbyterian Hospital, Weill Medical College of Cornell University, New York, New York, USA
Abstract:
Surgical patients are at high risk to develop nosocomial pneumonia, although an accurate diagnosis is difficult to make. Staphylococcus aureus and Pseudomonas aeruginosa are the most common pathogens, but Acinetobacteris emerging as an important pathogen. Because affected patients are often critically ill with multisystem pathology, it can be difficult to ascribe morbidity or mortality directly to the infection.
Insights
Nosocomial pneumonia is a risk for surgical patients, with Staphylococcus aureus and Pseudomonas aeruginosa common. Acinetobacter is an emerging pathogen, complicating diagnosis and attributing outcomes in critically ill patients.
Area of Science:
- Infectious Diseases
- Critical Care Medicine
- Surgical Infections
Background:
- Surgical patients face a high risk of developing nosocomial pneumonia.
- Accurate diagnosis of nosocomial pneumonia in this population is challenging.
- Common pathogens include Staphylococcus aureus and Pseudomonas aeruginosa, with Acinetobacter emerging.
Purpose of the Study:
- To highlight the diagnostic challenges of nosocomial pneumonia in surgical patients.
- To identify common and emerging pathogens responsible for nosocomial pneumonia.
- To discuss the difficulties in attributing morbidity and mortality to infection in critically ill surgical patients.
Main Methods:
- Literature review of nosocomial pneumonia in surgical settings.
- Analysis of common and emerging microbial pathogens.
- Discussion of diagnostic and attribution challenges in critically ill patients.
Main Results:
- Nosocomial pneumonia is a significant complication in surgical patients.
- Staphylococcus aureus and Pseudomonas aeruginosa are prevalent pathogens.
- Acinetobacter is an increasingly important pathogen in this demographic.
Conclusions:
- Accurate diagnosis of nosocomial pneumonia in surgical patients remains difficult.
- The emergence of pathogens like Acinetobacter requires updated diagnostic and treatment strategies.
- Multisystem pathology in critically ill patients complicates the direct attribution of outcomes to infection.

The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed.

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
