The Effect of Incentive Spirometry and Respiratory Physiotherapy on Improving Respiratory Function in Patients Following Chest Injuries

The effect of incentive spirometry and respiratory physiotherapy on improving respiratory function in patients after chest injury

Clinical trial with control group; single-blind; randomized; on 64 patients; Random allocation software version 2 was used for randomization

After selection, demographic characteristics of patients were collected. The primary goals of this study included changes and results of PFT that were performed on all patients at the end of the third day of the study. the assessment of the patient's oxygenation status was recorded each time before and after the intervention. In the intervention group, both incentive spirometry and respiratory physiotherapy were used, while in the control group, only respiratory physiotherapy exercises were performed.

Inclusion criteria: Age range 18-65 years, consciousness, injury severity score ≥11, non-penetrating injury with rib fracture ≥1 Exclusion criteria: unwillingness to participate, loss of consciousness level <14, chronic obstructive pulmonary disease, asthma, history of heart disease, venous obstruction, coagulation problems after abdominal, thoracic, brain and eye surgery

The correct method of incentive spirometry involves placing the patient in a semi-sitting position and maintaining a deep breath for a maximum of 2 to 3 seconds and then exhaling. This process was performed daily for at least one hour for three consecutive days, 10 times a day in the intervention group. Respiratory physiotherapy exercises were performed under supervision of two trained nurses in both groups. In the comparison group, incentive spirometry wasn't performed

Pulmonary oxygen saturation (SpO2), and ABG status including pH, pO2 and pCO2, and FVC; FEV1; (FEV1/FVC) before and after the intervention between control and intervention group

In this study, a restricted randomization method of block randomization with a ratio of 1:1 and a block size of four was used. Random allocation software version 2.0 was used to randomize the samples. In addition to simple randomization, this software was able to generate a random sequence using the block method, and as a result, this software was used for randomization simultaneously with blocking the samples. In order to maintain homogeneity of sample distribution and the frequency of chest injuries (penetrating and non-penetrating), the control and intervention groups included 18 patients with non-penetrating injuries and 14 patients with penetrating injuries to the chest.

In order to blind the study, a statistician independent of the study was responsible for the random assignment of participants to each of the two groups and the final analysis of the data. As a result, one-way blinding was utilized in this study.

All data from the study, study protocol, statistical analysis map, statistical analysis form, patient consent form, clinical study report, and codes used in data analysis were used in the student thesis of Dr. Lotf Mohammadi and the published article at the end of the study, and will be visible on the website of the Department of General Surgery of Kerman University of Medical Sciences in the student theses section after 6 months from the publication of the article.

The data access period begins 6 months after the results are published.

The data will be accessible to the public after obtaining permission from the Vice Chancellor for Research and the Ethics Committee of Kerman University of Medical Sciences.

The data will be available for use by other researchers for statistical analysis and use in other research after obtaining permission from the Vice President for Research and the Ethics Committee of Kerman University of Medical Sciences.
