"Blind" placement of plastic left double-lumen tubes

Area of Science:

• Anesthesiology
• Thoracic Surgery
• Respiratory Medicine

Background:

• Left-sided double-lumen tubes (DLTs) are crucial for one-lung ventilation during thoracic surgery.
• Accurate and rapid DLT placement is essential for patient safety and procedural efficiency.

Purpose of the Study:

• To prospectively evaluate the efficacy and safety of "blind" placement of left-sided plastic DLTs.
• To assess the time required for DLT intubation and identify common placement challenges.

Main Methods:

• Prospective analysis of 100 patients undergoing thoracic procedures requiring left-sided DLTs.
• Placement guided solely by auscultation and clinical signs, without routine bronchoscopic confirmation.
• Documentation of intubation time, initial tube position, and any intraoperative complications.

Main Results:

• Successful "blind" left main bronchus intubation in 91% of patients.
• DLT placement completed in under five minutes for 84% of patients.
• The most frequent issue was initial right main bronchus intubation (30%), requiring bronchoscopic intervention in 7 cases; minor malpositions occurred in 4%.

Conclusions:

• "Blind" placement of left-sided plastic DLTs is a feasible and efficient technique for thoracic surgery.
• While generally successful, awareness of potential right main bronchus intubation is necessary for prompt correction.
• The technique allows for rapid and safe initiation of one-lung ventilation in the majority of patients.
