Video double-lumen endotracheal tube reduces hypoxemia during one-lung ventilation in thoracoscopic surgery: a prospective randomized controlled trial.

Background: Compared to the conventional double-lumen endotracheal tube (c-DLT), the video double-lumen endotracheal tube (v-DLT) demonstrates a shorter intubation time and the capability of observing and adjusting malposition at any time. Our objective was to compare the incidence of hypoxemia during one-lung ventilation (OLV) and perioperative complications between the two tube types. Methods: This single-center, prospective, randomized controlled trial enrolled 100 patients undergoing video-assisted thoracic surgery (VATS), who were randomized to receive either a v-DLT or a c-DLT. The primary outcome was the incidence of hypoxemia [defined as a peripheral oxygen saturation (SpO Results: The incidence of hypoxemia during OLV was significantly lower in the v-DLT group compared to the c-DLT group [3/48 (6.3%) Conclusions: The use of v-DLT significantly reduces the incidence of hypoxemia during OLV, decreases the need for rescue interventions and FOB. Simultaneously, it improves procedural efficiency and enhances anesthesiologist satisfaction. Trial Registration: Chinese Clinical Trial Registry ChiCTR2100046484.
