Stellate ganglion block for attenuating postoperative sore throat after double-lumen tube intubation in thoracic surgery: a randomized clinical study
Authors' conclusion
Preoperative ultrasound-guided SGB significantly alleviates POST and reduces the early postoperative cough incidence in thoracic surgery patients undergoing DLT intubation.
Study context
- Population
- Patients undergoing elective thoracic surgery with double-lumen tube (DLT) intubation
- Participants
- 120 patients
- Comparison
- Stellate ganglion block (SGB) vs Control
- SGBn = 60
- Controln = 60reference
- Primary endpoint
- Incidence and severity of POST and throat pain visual analogue scale (VAS) scores
Methodological detailsprospective, double-blind
- Prospective
- Double-blind
Primary result
As reported in the abstract
Incidence of POST · 1 h, 6 h and 24 h postoperatively
SGB
10.3%, 13.8%, and 5.2%
Control
44.1%, 35.6%, and 20.3%
P < 0.05
Secondary outcomes
Cough incidence · 1 h and 6 h · same values at both time points
P = 0.014
| Outcome | SGB | Control | P value |
|---|---|---|---|
| Throat VAS score · 1 h and 6 h postoperativelySignificantly lower in the SGB group · primary outcome component | 0.45 and 0.34 ± 1.45 and 1.05 | 1.88 and 0.93 ± 2.54 and 1.41 | P < 0.05 |
