Pharyngeal reperforation following incentive spirometry: A case report

Despite its widespread use, complication of incentive spirometry has been rarely reported. We report a case of pharyngeal reperforation following incentive spirometry. A 75-year-old female, had a history of long-term steroid use, entered the intensive care unit for maintenance of mechanical ventilation following surgical repair of a pharyngeal perforation. After ventilator weaning, incentive spirometry was implemented on postoperative day 4. Immediately after incentive spirometry use, patient's neck began to swell, and subcutaneous emphysema was palpated. Pharyngeal reperforation was suspected on neck computed tomography, and emergency surgery was performed. Surgery revealed a 3-cm long rupture from the hypopharynx to the esophagus. The causes were thought to be delayed wound healing due to long-term steroid use and a sudden increase in pharyngeal pressure due to incentive spirometry. In conclusion, particular attention should be paid when using incentive spirometry after head and neck surgery in patients with a history of long-term steroid use.

Change in Pulmonary Function after Incentive Spirometer Exercise in Children with Spastic Cerebral Palsy: A Randomized Controlled Study

PURPOSE: The aim of this study was to investigate the effect of incentive spirometer exercise (ISE) on pulmonary function and maximal phonation time (MPT) in children with spastic cerebral palsy (CP). MATERIALS AND METHODS: Fifty children with CP were randomly assigned to two groups: the experimental group and the control group. Both groups underwent comprehensive rehabilitation therapy. The experimental group underwent additional ISE. The forced vital capacity (FVC), forced expiratory volume at one second (FEV1), FEV1/FVC ratio, peak expiratory flow (PEF), and MPT were assessed as outcome measures before and after 4 weeks of training. RESULTS: There were significant improvements in FVC, FEV1, PEF, and MPT in the experimental group, but not in the control group. In addition, the improvements in FVC, FEV1, and MPT were significantly greater in the experimental group than in the control group. CONCLUSION: The results of this randomized controlled study support the use of ISE for enhancing pulmonary function and breath control for speech production in children with CP.
