OBJECTIVE: To evaluate the efficacy of ultrasound-guided thyroid cartilage plane block (TCPB) on postoperative sore throat (POST) in patients undergoing suspension laryngoscopy vocal cord polypectomy (SLVCP).
METHODS: Ninety patients scheduled for elective SLVCP were randomized to either the TCPB group (general anesthesia + ultrasound-guided TCPB) or the C group (conventional GA), with 45 patients in each. The primary outcome was the incidence of POST at 2 h after extubation. Secondary outcomes included the incidence and severity of POST at 0.5, 2, 6, 12, and 24 h after extubation; the incidence and severity of hoarseness at 0.5, 2, 6, 12, and 24 h after extubation; and cough response during emergence.
RESULTS: The incidence of POST was significantly higher in the C group compared to the TCPB group at 0.5 h (93% vs. 67%, RR = 0.20, 95% CI [0.06-0.64]; P = 0.003), 2 h (78% vs. 47%, RR = 0.42, 95% CI [0.23-0.77]; P = 0.004), and 6 h (64% vs. 27%, RR = 0.49, 95% CI [0.32-0.77]; P = 0.001) after extubation. No significant difference in the incidence and severity of hoarseness between the groups at any time point. During extubation, the incidence of cough response in the C group was 60%, significantly higher than the 20% in the TCPB group (RR = 0.50, 95% CI [0.34-0.74]; P = 0.001).
CONCLUSION: Ultrasound-guided TCPB significantly reduces the incidence and severity of POST and cough response in SLVCP patients.
