Summary

A validated prognostic index accurately predicts postoperative pulmonary complications in upper abdominal surgery patients. Age over 56, prolonged surgery, and lung disease are key risk factors, with complications being the sole predictor of mortality.

Area of Science:

  • Thoracic Surgery
  • Pulmonary Medicine
  • Surgical Outcomes

Background:

  • Postoperative pulmonary complications (PPCs) are a significant concern following major abdominal surgery.
  • Accurate prediction of PPC risk is crucial for patient management and resource allocation.

Purpose of the Study:

  • To validate the Pereira prognostic index for predicting PPCs in patients undergoing elective upper abdominal surgery.
  • To identify independent risk factors for mortality in this surgical population.

Main Methods:

  • A prospective cohort study involving 283 patients undergoing elective upper abdominal surgery.
  • Preoperative assessment included clinical questionnaires, physical exams, chest X-rays, and spirometry.
  • Data collected: patient characteristics, surgical details, ICU stay, hospitalization duration, and PPC occurrence.

Main Results:

  • PPCs occurred in 24.4% of patients, with pneumonia and atelectasis being most common.
  • Age > 56, surgery duration > 210 minutes (DS > 210), and chronic pneumopathy were associated with increased PPC risk.
  • The Pereira index demonstrated validity in predicting PPCs; inclusion of FEV1/FVC refined risk stratification.
  • Postoperative pulmonary complication was the only significant predictor of mortality.

Conclusions:

  • The Pereira prognostic index is a valid tool for estimating PPC risk after elective upper abdominal surgery.
  • Age, surgery duration, and pre-existing lung disease are significant predictors of PPCs.
  • PPCs are the primary independent risk factor for mortality in this patient group.
