Note: Compared with group L, aP < 0.05; group L: aerosol inhalation group; group S: medial branch block of superior laryngeal nerve group; T0: immediately before treatment; T1: 10 minutes after treatment; T2: 30 minutes after treatment; T3: 1 hour after treatment; T4: 2 hours after treatment; T5: 4 hours after treatment; T6: 8 hours after treatment; T7: 24 hours after treatment.
P values were calculated using t test.
