Preoperative US-guided iSLNB could significantly ameliorate the incidence and severity of POST induced by double-lumen bronchial catheter intubation.
Study context
- Population
- Patients undergoing thoracoscopic resection of pulmonary nodules/lobes/segments with one-lung ventilation (OLV) under general anesthesia (GA) and double-lumen tube intubation
- Participants
- 82 patients
- Comparison
- Preoperative bilateral US-guided iSLNB plus GA vs GA alone
- Sn = 41
- Cn = 41reference
- Primary endpoint
- Incidence of POST
- Follow-up
- 6 hours after surgery

|---|---|---|---|---|
| Overall accumulated incidence of POST | 9/41 | 20/41 | 0.30 (95% CI 0.11–0.77) | P = 0.011 |
| Incidence and severity of POST · 2 hours after surgeryIncidence P = .008; severity P = .004 | 9/41 | 20/41 | 0.30 (95% CI 0.11–0.77) | P = 0.008 |
Incidence and severity of postoperative sore throat (POST) · 24 hours after surgery
- Nonsignificant difference between groups
Incidence and severity of hoarseness · 2, 6, and 24 hours after surgery
- Comparable between the 2 groups
