Trial Outcomes & Findings for Video Double-Lumen Tube Prospective Randomized Study (NCT NCT02429414)

NCT ID: NCT02429414

Last Updated: 2022-03-29

Results Overview

The rate of FOB use for the VDLT arm and the Double-Lumenendobronchial Tubes (DLT) arm was calculated. The Fisher's exact test or chi-square test was used to evaluate the association between 2 categorical variables. Wilcoxon rank-sum test was used to evaluate the difference in a continuous variable. Rate of fiberoptic use with the Video Double-Lumen Tube (VDLT) during surgeries requiring lung isolation and to compare to the rate of Fiberoptic Bronchoscopy (FOB) use with the conventional DLT.

Measure
Mallinckrodt Double Lumen Tube (DLT)
Participants receive a non-video DLT for lung isolation before surgery. Once non-video DLT is in correct place, its final position before surgery checked with a fiberoptic bronchoscopy (FOB). Non-Video Double Lumen Tube (DLT): Participant receives non-video double lumen tube (DLT) placement before surgery. Fiberoptic Bronchoscopy (FOB): Fiberoptic bronchoscopy (FOB) performed to check placement of non-video DLT. Under General Anesthesia, the Double Lumen Tube (DLT) was inserted with conventional laryngoscopy or video laryngoscopy as per the preference of the anesthesiologist. Attending anesthesiologists performed all the intubations.
Vivasight Video Double Lumen Tube (VDLT)
Participants receive a VDLT for lung isolation before surgery. Once VDLT is in correct place, its final position before surgery checked with the camera inside the tube. Video Double Lumen Tube (VDLT): Participant receives video double lumen tube (VDLT) placement before surgery. Under General Anesthesia, the Video Double Lumen Tube (VDLT) was inserted with conventional laryngoscopy or video laryngoscopy as per the preference of the anesthesiologist. Attending anesthesiologists performed all the intubations. Prior to insertion, the VDLT was connected to its accompanying external monitor via a mini universal serial bus port.
