Abstract

Abstract : Aim: Pulmonary complications (PCs) are a major cause of poor prognosis in chest trauma. Evidence on the effectiveness of incentive spirometry (IS) in trauma is scarce. This study investigated the effectiveness of IS in preventing PCs in patients with chest trauma with rib fractures. Methods: This retrospective observational study analyzed the data obtained from the electronic medical records of patients with chest trauma with rib fractures admitted between 2011 and 2019. We included patients 18 years of age or older with risk of worsening respiratory failure. Early IS was the primary exposure and PCs (pulmonary infection or respiratory failure requiring escalating oxygen therapy) were the primary outcomes. Secondary outcomes were length of hospital stay, duration of oxygenation therapy, and adverse events of IS. Logistic regression analysis with a propensity score was used. Results: We extracted 514 patients from the electronic medical records; 299 patients were included. The early IS group had a higher proportion of hypoxemia at admission, opioid analgesia use, invasive positive pressure ventilation, and respiratory physiotherapy. The severity of trauma was higher in the early IS group. There was no significant difference in the occurrence of the PCs between groups (adjusted odds ratio 0.71; 95% confidence interval, 0.24–2.16). No statistical differences were seen in the secondary outcomes. Conclusion: For patients with chest trauma with rib fractures at risk of worsening respiratory failure, IS early after injury did not reduce the rate of PCs. No adverse event of IS was observed and IS was shown to be safe. Abstract : Incentive spirometry early after chest trauma was not significantly associated with a lower incidence of pulmonary complications. No adverse events due to incentive spirometry were observed in patients with chest trauma. This study presents the first data on the effect of incentive spirometry on chest trauma with the risks of worsening respiratory failure.
