Effects of Preoperative Stellate Ganglion Block on Postoperative Sore Throat and Hoarseness in Patients Undergoing Double-Lumen Endobronchial Intubation: Protocol for a Prospective Randomized Controlled Trial.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Postoperative sore throat (POST) is a common complication after general anesthesia, especially following double-lumen endobronchial tube (DLT) intubation in thoracic surgery, adversely affecting recovery. Stellate ganglion block (SGB) modulates sympathetic tone and inflammation, potentially reducing airway complications, but its efficacy for POST and hoarseness after DLTs remains unclear. Objective: To evaluate the impact of preoperative SGB on the incidence and severity of POST and hoarseness in patients undergoing DLT intubation, and to explore its effects on postoperative sleep, anxiety, depression, and hemodynamics. Methods: In this single-center, prospective, randomized controlled trial, 124 patients scheduled for thoracic surgery with left DLT intubation are to be included. Patients will be randomly assigned in a 1:1 ratio to the SGB group or the control group. Patients in the SGB group will receive ultrasound-guided right SGB (5 mL of 0.5% ropivacaine) approximately 30 minutes before anesthesia induction. In the control group, ultrasound-guided scanning of the stellate ganglion will be conducted without performing SGB, and local lubrication with 1% tetracaine gel will be administered prior to intubation. The primary outcome is the incidence of POST at 6 hours after surgery. Discussion: This trial will determine whether SGB can effectively reduce POST and hoarseness after DLT intubation, potentially offering a multimodal strategy to improve postoperative recovery in thoracic surgery patients.
