Summary

A case report highlights that using a Univent tube for one-lung ventilation (OLV) can lead to pulmonary soiling. Accumulated secretions near the bronchial blocker may contaminate both dependent and non-dependent lung areas during OLV.

Area of Science:

  • Anesthesiology
  • Thoracic Surgery
  • Pulmonary Medicine

Background:

  • One-lung ventilation (OLV) is crucial for thoracic surgeries.
  • Univent tubes are used to facilitate OLV by blocking specific bronchi.
  • Effective management of secretions during OLV is essential to prevent lung complications.

Observation:

  • A case of pulmonary soiling occurred in both dependent and non-dependent lung regions after using a Univent tube for OLV.
  • Abundant blood-tinged secretions were aspirated upon cuff deflation, indicating ineffective removal through the blocker's lumen.
  • Postoperative chest radiography revealed haziness in multiple lung lobes.

Findings:

  • Ineffective secretion removal through the Univent tube's lumen is a potential disadvantage.

  • Placement of the bronchial blocker in the non-dependent bronchus may increase contamination risk to the dependent lung.
  • Accumulated secretions distal to the blocker pose a risk of contaminating remaining lung tissue.

    • Implications:

    • Caution is advised when using bronchial blockers for OLV due to potential lung soiling.
    • Strategies like steep Trendelenburg positioning and intraoperative bronchoscopy with suction may mitigate risks.
    • Further research into optimizing secretion management during OLV with bronchial blockers is warranted.
