A Comparative Study of the Efficacy of an Improved Double-Lumen Tube Ventilation Control Device Versus A Conventional Device in Thoracic Surgery: A Randomized Controlled Trial

Abstract Background: To improve the conversion efficiency between single-lung and double-lung ventilation after Double-lumen tube(DLT) intubation, we invented a Y-shaped rotatable adjustment between three-lumen tube and double-lumen tube connector (YRC). The performance of YRC was studied with the traditional Y-shaped reconnector (YC) as the control. Methods: A total of 60 adult patients who underwent thoracic surgery with double-lumen endotracheal tube insertion were included in the study. The subjects after endotracheal tube insertion were randomly divided into two groups: YRC connecting group (YRC group, n=30) and a traditional connector connecting group (YC group, n=30), respectively. Primary endpoints were intubation time and conversion time of single-lung ventilation to double-lung ventilation. The secondary endpoints of this study were the internal gas volume of the two joints, airway pressure, and the time required for sputum aspiration during the operation. Results: Intubation time in YRC group was shorter than that in YC group (89.75±14.28s vs 107.80±14.96s, p=0.00). Compared with the YC group, the time required for ventilation conversion between single-lung and double-lung ventilation during the operation in the YRC group were significantly shortened (3.60±1.20svs9.05±2.53s, p=0.00). The internal gas volume in YRC (17.20ml) is smaller than YC (24.12ml). There was no statistical difference in airway pressure and the time required for sputum aspiration between YRC group and YC group (P > 0.05). Conclusion: Compared with the traditional connectors, the YRC can improve the conversion efficiency between single-lung ventilation and double-lung ventilation with double-lumen endotracheal tube, save positioning time, and can be safely used for the anesthesia management of double-lumen endotracheal tube. Trial registration: This clinical research was registered at the Chinese Clinical Trial Registry(www.chictr.org.cn,ChiCTR2000040188).

Endotracheal Tube Placement

Tracheobronchial disruption is an uncommon but severe complication of double lumen endotracheal tube placement. The physical properties of a double lumen tube (large external diameter and length) make tracheobronchial injury more common than that associated with smaller single lumen endotracheal tubes. Here we present the case of an iatrogenic left main bronchus injury caused by placement of a double lumen tube in an otherwise unremarkable airway.

One-lung ventilation can be achieved with a double-lumen tube or a bronchial blocker. However, the larger outer diameters of double-lumen or Univent tubes may prevent their passage through an area of subglottic stenosiss. We present five cases of subglottic stenosis in which a Fogarty catheter was used as a bronchial blocker through a single-lumen endotracheal tube. The outer diameters of a double-lumen tube, Univent tube and single-lumen tube were compared. Despite special equipment designed for one-lung ventilation, the use of a bronchial blocker through a single-lumen tube, which has the thinnest available wall thickness, seems to be one of the most effective and safest ways of achieving one-lung ventilation in patients with subglottic stenosis or narrowing.

Double Lumen Endobronchial Tube

We describe the insertion of the double lumen endobronchial tube (DLT) using a non-channeled standard blade of the King VisionTM videolaryngoscope for one lung ventilation (OLV) in a morbidly obese patient with a predicted difficult airway, severe restrictive pulmonary function, asthma, and hypertension. The patient was scheduled for a video-assisted thoracoscopic lung biopsy. The stylet of the DLT was bent to fit the natural curve of the #3 non-channeled blade of the King Vision™ videolaryngoscope. We conclude that the use of King Vision™ videolaryngoscope could offer an effective method of DLT placement for OLV.
