Background: Thoracic surgery often demands separation of ventilation between the lungs. It is achieved with double-lumen tubes (DLTs), video double-lumen tubes (VDLTs) or bronchial blockers. We tested the hypothesis that intubation with the VivaSight double-lumen tube would be easier and faster than with a standard DLT.
Methods: Seventy-one adult patients undergoing thoracic procedures that required general anaesthesia and one-lung ventilation (OLV) were enrolled in this randomized, prospective study. Patients were randomly assigned to procedure of intubation with a standard DLT or VDLT. The collected data included: patients' demographics, surgery information, anthropometric tests used for difficult intubation prediction, specifics of intubation procedure, tube placement, fiberoptic bronchoscopy (FOB) use, lung separation, trachea temperature, and reported complications of intubation.
Results: For DLTs compared to video-double lumen tubes, intubation time was significantly longer (125 44 s; P<0.001), intubation graded harder (P<0.05) and FOB use was more prevalent [8 (20.5%) 0; P<0.05].
Conclusions: The use of VDLTs when compared with standard-double lumen tubes offers reduced intubation time and is relatively easier. Also, the reduced need for fibreoptic bronchoscopy may improve the cost-effectiveness of VDLT use. In addition, constant visualization of the airways during the procedure allows to quickly correct or even prevent the tube malposition.

The double-lumen endotracheal tube (DLT) was introduced by Carlens in 1949 and became widely used for single-lung ventilation. DLTs have since become standard for most pulmonary resections. Although the use of DLTs is routine and safe in experienced hands, it is not without risk.

Background: Hypoxemia occurs with relative frequency during one-lung ventilation (OLV) despite advances in airway management. Lung perfusion scans are thought to be one of the most accurate methods to predict hypoxemia during OLV, but their complexity and costs are well-known limitations. There is a lack of preoperative stratification models to estimate the risk of intraoperative hypoxemia among patients undergoing thoracic surgery.

In recent decades, the advantages of minimizing surgical trauma have led to the development of minimally invasive surgical procedures. While the benefits often outweigh the risks, several challenges are encountered that are not present in conventional surgical approaches. Unilateral pulmonary edema (UPE) after mitral interventions performed through a right-sided approach is a rare but potentially life-threatening event.

Innovations and challenges for lung separation or isolation have evolved during the last few years. In this chapter, we present the up-to-date, robust evidence available during the previous five years supporting the positions of the different devices, techniques, and tricks for their use in adult and pediatric patients undergoing various thoracic surgical interventions. Additionally, we presented an update on lung isolation in patients with airway difficulty and the suggested training level to master these techniques.

Reintubation in such cases is challenging and may cause additional traumatic laryngitis. Tracheostomy is the best management for subglottic stenosis after DLT intubation.
