Summary

Accurate double-lumen tube (DLT) sizing is crucial. This study found that left bronchial diameter in male patients can be predicted using age and height, aiding DLT selection.

Area of Science:

  • Anesthesiology
  • Thoracic Surgery
  • Radiology

Background:

  • Proper sizing of double-lumen tubes (DLTs) is essential for effective one-lung ventilation during thoracic surgery.
  • Left mainstem bronchial diameter is a key determinant for selecting the appropriate DLT size.
  • Predicting bronchial diameter preoperatively can improve surgical planning and patient safety.

Purpose of the Study:

  • To investigate if left bronchial diameter can be reliably estimated from patient demographics.
  • To establish a predictive formula for left mainstem bronchial diameter in adult patients.

Main Methods:

  • Retrospective analysis of 100 adult patients' preoperative chest X-rays.
  • Measurement of left bronchial diameter and correction for PA view magnification.

  • Multiple linear regression analysis to correlate bronchial diameter with age, sex, height, weight, and body surface area.

    • Main Results:

    • Left mainstem bronchial diameter differed significantly between sexes (males: 12.4 mm, females: 10.7 mm).
    • In female patients, no demographic variable significantly predicted bronchial diameter.
    • In male patients, age and height were significant predictors (p < 0.05), leading to a predictive formula: diameter = 0.032*age + 0.072*height - 2.043.

    Conclusions:

    • A predictive formula based on age and height can estimate left bronchial diameter in male patients.
    • This formula may assist in selecting the correct double-lumen tube size for male patients undergoing thoracic procedures.
    • Further research may be needed to develop similar predictive tools for female patients.
