Association between postoperative cough and thyroidectomy: a prospective study
BMC Cancer 19, Article number: 754 (2019)
Abstract
Background
This study sought to determine whether thyroidectomy is associated with self-reported cough through a prospective analysis.
Methods
Patients undergoing unilateral thyroidectomy were prospectively enrolled. The control group was selected to avoid the effect of general anaesthesia. The experimental group consisted of 300 patients (202 females and 98 males) who underwent thyroidectomy, with a mean age of 48.6 years, and the control group consisted of 103 patients (53 females and 50 males) who underwent other head and neck operations, with a mean age of 50.3 years. All patients were required to complete the Leicester Cough Questionnaire (LCQ) preoperatively and 2 weeks postoperatively.
Results
The postoperative mean total LCQ scores in the experimental and control groups were 17.9 ± 5.0 and 19.8 ± 4.2, respectively; the difference was significant (p = 0.014). Adverse event analysis showed that patients in the experimental group scored significantly worse on items for chest or stomach pains, phlegm, feeling in control of coughing, sleep disturbances, coughing bouts, frustration, and feeling fed up with coughing. In the analysis of the three LCQ domains, a significant difference was noted in the physical domain between the two groups (p < 0.001). In the one-way analysis of variance, the factors of sex and anaesthesia time were associated with the postoperative LCQ score; in further multifactor analysis of variance, only the factor of sex was significantly related to the postoperative LCQ score.
Conclusion
Thyroidectomy may be associated with postoperative cough, and a higher number of female patients complained of cough and related symptoms.
