This study presents a novel laser surgery technique for endobronchial procedures. The method uses a specialized catheter for ventilation, effectively preventing lung complications and improving oxygen saturation during recovery.

Area of Science:

  • Pulmonology
  • Surgical Technology
  • Laser Surgery

Background:

  • Endobronchial surgery presents challenges in maintaining ventilation and preventing complications.
  • Laser use in endobronchial procedures necessitates methods to protect the airway from smoke and debris.

Purpose of the Study:

  • To describe and evaluate a novel technique for endobronchial surgery using a neodynium:yttium-aluminum-garnet laser.
  • To assess the efficacy of selective ventilation via an insufflation catheter in preventing lung complications.

Main Methods:

  • A technique involving an insufflation catheter with side holes placed in the contralateral mainstem bronchus for high-frequency positive pressure ventilation.
  • General anesthesia with rigid and fiberoptic bronchoscopes was used in 35 patients (45 procedures).

  • Perioperative monitoring of oxygen saturation (SaO2), mean arterial pressure, and heart rate.

    • Main Results:

    • Oxygen saturation during recovery was comparable to intraoperative levels and significantly higher than pre-anesthesia levels (P < 0.05).
    • Six patients showed a significant increase in SaO2 post-treatment, indicating successful airway recanalization.
    • Selective ventilation of the nonaffected lung was adequate during endobronchial resection.

    Conclusions:

    • The described technique, utilizing an insufflation catheter with side holes, largely prevented laser smoke inhalation and aspiration of blood and debris.
    • Subcarinal placement of the insufflation catheter was advantageous.
    • This technique contributes to preventing lung complications during endobronchial laser surgery.
