Brief Summary

The aim of this study was to determine the accuracy and practicality of ultrasound in the selection of double lumen tube and whether the complications that may occur intraoperatively and postoperatively can be reduced. Patients aged 18-75 years with ASA 1-2-3 who give informed consent for left double lumen tube placement for single lung ventilation will be included in this study. Patients with a history of previous difficult intubation, head and neck surgery and radiotherapy, class 3-4 in the Colmark-Lehane classification by the thoracic anaesthetist who will perform the intubation, and patients with previously known hoarseness and chronic cough will not be included in the study. Patients who accept the study will be randomly assigned to one of the anaesthesia groups including ultrasound group (Group 1) and classical method (Group 2). Randomisation will be in a 1:1 ratio and will be done by closed envelope method.

Conditions

One-Lung Ventilation; Thoracic Surgery

Keywords

Ultrasound; Double lumen tube; Postoperative complication

Outcome Measures

Primary Outcomes (1)

• postoperative cough and sore throat

  Zero: No sore throat; 1: Mild, sore throat only when swallowing; 2: Moderate, persistent sore throat, aggravated when swallowing; 3: Severe, throat pain affecting the patient's eating, and analgesic drugs were needed

  postoperative first at 24 hours

Study Arms (2)

Ultrasound

ACTIVE COMPARATOR

While the patients were in the supine position on the operating room table, the external tracheal diameter, measured just above the sternoclavicular junction, was measured by ultrasound. Appropriately sized tube size was selected in accordance with previous studies and cadaver studies.

Other: Ultrasound

conventional

ACTIVE COMPARATOR

For female patients, a 37 fr left double lumen tube was chosen for patients taller than 160 cm, and a 35 fr left double lumen tube was chosen for patients shorter than 160 cm. For male patients, a 41 fr left double lumen tube was selected for patients taller than 170 cm and a 39 fr tube was chosen for men shorter than 170 cm.

Other: Ultrasound
