Summary

Routine fiberoptic bronchoscopy is crucial for selecting lung donors. Standard chest X-rays and arterial blood gas analysis are insufficient for assessing lung viability in brain-dead donors.

Area of Science:

  • Transplantation Science
  • Pulmonary Medicine
  • Critical Care Medicine

Background:

  • Lung donor selection traditionally relies on chest X-ray and arterial blood gas (ABG) analysis.
  • Normal bronchoscopy is not always a mandatory criterion for lung procurement.
  • Brain-dead donors present unique challenges in assessing lung suitability for transplantation.

Purpose of the Study:

  • To evaluate the efficacy of fiberoptic bronchoscopy in assessing lung donor suitability.
  • To determine if chest X-ray and ABG analysis are sufficient for lung donor selection.
  • To investigate the prevalence of abnormalities in brain-dead lung donors.

Main Methods:

  • Prospective study involving 72 brain-dead donors undergoing organ procurement.
  • Assessment included chest X-ray, arterial blood gas analysis (PaO2 with FIO2 100%), and fiberoptic bronchoscopy.

  • Pulmonary shunt and arteriovenous oxygen content difference were measured in a subset of donors.

    • Main Results:

    • Only 51% of donors had normal chest X-rays and 47% had adequate gas exchange (PaO2 > 400 mm Hg on FIO2 100%).
    • Fiberoptic bronchoscopy revealed abnormalities in 67% of donors, including gastric aspiration (36%) and purulent secretions (5%).
    • Even among donors with normal chest X-rays and ABG values, 38% had abnormal bronchoscopies.

    Conclusions:

    • Chest X-ray and ABG analysis are inadequate for comprehensive lung donor assessment.
    • Fiberoptic bronchoscopy should be routinely performed to identify lung abnormalities in potential donors.
    • Pulmonary shunt measurement offers a precise assessment of gas exchange in brain-dead lung donors.
