• Registration Number: NCT05472350
• Lead Sponsor: Jianxing He

Brief Summary

Cough after lobectomy is common. The prevention and treatment of cough after lobectomy is not standardized. Breztri Aerosphere is often used to relieve cough. Therefore, we conduct a single center placebo-controlled study to evaluate the efficacy and safety of perioperative use of Breztri Aerosphere in relieving cough after lobectomy.

Detailed Description

This study is a single-center, prospective, randomized, controlled clinical trial to understand the efficacy and safety of perioperative use of Breztri in relieving cough after lobectomy. This study plans to include 128 subjects from the Department of Thoracic Surgery of the First Affiliated Hospital of Guangzhou Medical University. Participants will be randomly divided into according Breztri group and placebo group to the ratio of 1:1. Participants in Placebo group will receive 0.9% normal saline for 3 days before operation and 14 days after operation (n=64). Participants in Breztri group will receive Breztri for 3 days before operation and 14 days after operation (n=64). All patients will undergo screening and baseline visits. After sugery, they will be followed up for 2 months.

Arm && Interventions

Group	Intervention	Description
Placebo Group	Placebo	Participants will receive 0.9% normal saline twice a day from 3 days before surgery to 14 days after surgery
Breztri Aerosphere Group	Breztri Aerosphere	Participants will receive Breztri Aerosphere twice a day from 3 days before surgery to 14 days after surgery

Primary Outcome Measures

Name	Time	Method
Incidence of significant cough two weeks after surgery	12 weeks	Cough Evaluation Test (CET) is an easy way to assess the cough condition. A Visual Analogue Scale (VAS) is a cough rating scale. Significnant cough means VAS more than 3 or any item of CET score more than 2.

Secondary Outcome Measures

Name	Time	Method
The total and sub-scores of the Cough Evaluation Test (CET) score of each day after surgery	12 weeks	Cough Evaluation Test (CET) is an easy way to assess the cough condition
Incidence of significant cough 1 month after surgery	12 weeks	Cough Evaluation Test (CET) is an easy way to assess the cough condition. A Visual Analogue Scale (VAS) is a cough rating scale. Significnant cough means VAS more than 3 or any item of CET score more than 2.
LCQ-MC at 1 month after surgery	12 weeks	Leicester Cough Questionnaire in Mandarin-Chinese (LCQ-MC) is a useful questionnaire to evaluate cough after surgery
the number of days the cough lasts	12 weeks	the number of days the cough lasts
Cough start time	12 weeks	Days from surgery to onset of cough
Inflammatory factor levels in venous blood before and after surgery	12 weeks	we test the inflammatory factor 3 days before surgery and 1 day after surgery
length of postoperative hospital stay	12 weeks	length of postoperative hospital stay
Incidence of serious postoperative pneumonia	12 weeks	we make a chest radiograph after surgery to find the postoperative pneumonia
