Purpose:
This study aims to evaluate the effect of acupoint application on the prevention of postoperative sore throat (POST), cough, expectoration, hoarseness, and patient satisfaction after general anesthesia.
Design:
Randomized controlled trial.
Methods:
A randomized double-blind clinical trial was designed. In total, 112 participants scheduled for gynecology or general surgery under general anesthesia were randomly assigned to 1 of 2 groups. One was the acupoint application group (group A) that received a session of acupoint application over the acupoints of Tiantu (RN22), Neiguan (PC6, bilateral), Zusanli (ST36, bilateral), and Yongquan (KI1, bilateral). The other was the placebo group (group P) and received a session of sham acupoint application in the same acupoints. In virtue of the visual analog scale score, the effects of acupoint application were measured by the incidence of POST, cough, expectoration, and hoarseness before, 24 hours, and 48 hours after the intervention, and patient satisfaction after surgery.
Findings:
The incidence of POST was lower in group A versus group P at 24 hours [13 (24.5%) vs 23 (44.2%), P = .033] and at 48 hours [3 (5.7%) vs 15 (28.8%), P = .002]. Compared with group P, the visual analog scale of POST was dramatically lower in group A at 24 and 48 hours (P = .024; P < .001). Group A had a reduced incidence of cough, expectoration, and hoarseness than group P at 48 hours. In addition, patients in group A felt more satisfied postoperatively than patients in group P (96.2% vs 80.8%, P = .013).
Conclusions:
Acupoint application effectively relieved POST in adults following general endotracheal anesthesia, reduced the incidence of postoperative cough, expectoration, and hoarseness, as well as improved patient satisfaction.
