Lung isolation with a bronchial blocker placed in the lateral position for patients undergoing thoracic surgery: A multicenter, randomized clinical trial
Authors' conclusion
Lateral bronchial blocker placement reduced the incidence of malposition in patients undergoing thoracic surgery; it was associated with fewer complications and higher satisfaction scores.
Study context
- Population
- Adults aged ≥18 years scheduled for thoracic surgery, 7 tertiary hospitals in China306 completed
- Participants
- 324 adults
- Comparison
- Bronchial blocker placement in the lateral vs supine position
- Lateraln = 152
- Supinen = 154reference
- Primary endpoint
- Incidence of bronchial blocker malposition

Primary result
As reported in the abstract
P < 0.001
Secondary outcomes
Median
| Outcome | Lateral | Supine | P value |
|---|---|---|---|
| Times of bronchial blocker reposition | 0 (IQR 0,0) | 1.0 (IQR 1.0–2.0) | P < 0.001 |
| Intubation duration (single-lumen tube intubation plus bronchial blocker placement) | P = 0.089 | ||
| Patient and surgeon satisfaction scores | P < 0.001 |
Intubation duration (single-lumen tube intubation plus bronchial blocker placement)
- Median intubation duration similar between the two groups
Patient and surgeon satisfaction scores
- Higher satisfaction scores in the lateral group
Safety
| Outcome | P value |
|---|---|
| Postural injury | P < 0.001 |
Postural injury
- Lateral placement associated with lower incidences of postural injury
