Postoperative pneumonia (POP) is a frequent complication after lung resection, impacting patient outcomes. Bronchial colonization and specific patient factors increase the risk of developing this serious condition.

Area of Science:

  • Thoracic Surgery
  • Infectious Diseases
  • Pulmonary Medicine

Background:

  • Postoperative pneumonia (POP) is a significant, life-threatening complication following lung resection surgery.
  • Key aspects like incidence, causative agents, risk factors, and patient outcomes for POP remain incompletely understood.

Purpose of the Study:

  • To investigate the incidence, microbiology, predisposing factors, and outcomes associated with postoperative pneumonia in patients undergoing major lung resections.
  • To identify independent risk factors for the development of POP.

Main Methods:

  • A prospective observational study was conducted over six months involving patients undergoing major lung resections for noninfectious conditions.
  • Intraoperative bronchial aspirates were cultured, and patients suspected of pneumonia underwent bronchoscopic sampling and culture prior to antibiotic treatment.

Main Results:

  • The study included 168 patients, with a POP incidence of 25%. Common pathogens included Haemophilus and Streptococcus species.
  • Intraoperative bronchial colonization (22.8%) was a significant risk factor for POP (RR 2.54).
  • POP was associated with increased mortality, need for ventilation, longer ICU and hospital stays, and independent risk factors included COPD, resection extent, colonization, and male sex.

Conclusions:

  • In-hospital pneumonia is a frequent complication after lung resections, contributing significantly to patient morbidity and mortality.
  • Identifying and managing risk factors, such as bronchial colonization, is crucial for improving outcomes in these patients.
