NCT07163429

Brief Summary

The goal of this study is to evaluate whether topical flurbiprofen reduces the incidence and severity of postoperative sore throat (POST) and hoarseness in patients undergoing double-lumen tube (DLT) intubation for elective thoracic surgery. The main question is: Does topical flurbiprofen reduce POST and hoarseness compared with placebo in patients undergoing DLT intubation? Researchers will compare topical flurbiprofen spray with placebo spray. Participants will:

  • Receive a DLT sprayed with either topical flurbiprofen or placebo before intubation.
  • Be assessed for POST and hoarseness at 15 minutes, 2 hours, 12 hours, 24 hours, and 48 hours after surgery.

Study Arms (2)

Flurbiprofen group

EXPERIMENTAL

Participants will receive topical flurbiprofen spray (one spray on the bronchial cuff and two spray on the tracheal cuff, with a total dose of 8.75 mg of flurbiprofen) applied to both the tracheal and bronchial cuffs of the double-lumen tube before intubation

Drug: Flurbiprofen 8.75 MG

Control group

PLACEBO COMPARATOR

Participants will receive placebo spray (0.9% normal saline) applied to both the tracheal and bronchial cuffs of the double-lumen tube before intubation.

Drug: Saline spray

Interventions

Topical administration of placebo spray (0.9% normal saline) applied in the same manner as the active intervention, with one spray to the bronchial cuff and two sprays to the tracheal cuff of the double-lumen tube before intubation.

Control group

Topical administration of flurbiprofen 8.75 mg spray applied directly to the tracheal and bronchial cuffs of the double-lumen endobronchial tube before intubation. A total of three sprays will be applied: one spray to the bronchial cuff and two sprays to the tracheal cuff, immediately before intubation.
