简要总结
We hypothesize that the addition of modified incentive spirometry to standard postoperative chest physiotherapy will be associated with faster return to baseline/predicted pulmonary function and fewer postoperative pulmonary complications in patients following laparotomy.
详细描述
The primary objective of this study is to determine how quickly patients' peak expiratory flow measurement returns to baseline or predicted values following laparotomy with or without the assistance of modified incentive spirometry. The secondary objective is to assess the effectiveness of modified incentive spirometry in preventing postoperative pulmonary complications in patients following laparotomy. Specifically, this study will track length of stay, mortality, and evidence of pulmonary infection in both treatment and non-treatment arms.

研究组 & 干预措施
Modified incentive spirometry
Patients will be given a disposable incentive spirometer postoperatively and instructed to use the spirometer every hour while awake.
干预措施: Incentive Spirometry (Device)
Modified incentive spirometry
Patients will be given a disposable incentive spirometer postoperatively and instructed to use the spirometer every hour while awake.
干预措施: Postoperative chest physiotherapy (Other)
Postoperative chest physiotherapy
Patients will be given standard postoperative chest physiotherapy, according to hospital protocol, but will not receive incentive spirometers.

结局指标
主要结局
Return to baseline or predicted pulmonary function
时间窗: postoperative course up to discharge
Return to baseline/predicted pulmonary function based on peak expiratory flow measurement. Postoperative measurement will be compared to preoperative measurement (for elective cases) or age-predicted measurement (for emergency cases)
次要结局
- Incidence of postoperative pulmonary complications(postoperative course until discharge)
