Video double-lumen tube intubation in a modified lateral position for unilateral video-assisted thoracoscopic surgery: a randomized controlled trial

In patients undergoing unilateral VATS, VDLT intubation in a modified lateral position shortened IRCT. In exploratory analyses, several secondary outcomes favoured this approach. Intubation in a modified lateral position may be a feasible alternative to conventional supine position intubation in these patients.
Study context
- Population
- Adults aged 18–75 yr (American Society of Anesthesiologists Physical Status I–III) scheduled for elective unilateral video-assisted thoracoscopic surgery (VATS) requiring video double-lumen tube (VDLT) intubation, tertiary university hospital in Xi'an, Chinarandomized, all analyzed for the primary outcome
- Participants
- 62 adults
- Comparison
- VDLT intubation in a modified lateral position vs conventional supine intubation
