[P2-51] Efficacy of intrapulmonary percussive ventilation in severely disabled children with chronic respiratory disease
[Introduction]
Although intrapulmonary percussive ventilation (IPV) has been used in severely disabled children since the beginning of the 21st century, few reports have documented its efficacy. Herein, we investigated the efficacy of IPV in such children.
[Method]
Thirty patients (age range, 1.7 to 21 years; average age, 11.6±6.1 years) who received IPV during admission at the Ibaraki Prefectural University of Health Sciences Hospital between April 2013 and March 2016 were retrospectively evaluated using their clinical history and chest CT images. We used IPV for 1 to 123 days (average, 51 days). All patients had level V function according to the gross motor function classification system.
[Results]
Twenty-eight patients were successfully introduced to IPV, one refused treatment, and one showed apnea requiring manual ventilation for over 5 minutes for recovery. IPV was introduced because of fever elevation in seven and respiratory condition aggravation in 22. Four of the seven had aspiration pneumonia. IPV decreased sputum amount and elevation of percutaneous oxygen saturation (SpO2). Nine of the 28 patients showed decreased respiratory rate. Fourteen of the 19 who underwent chest CT showed an improvement of aspiration pneumonia or atelectasis.
Seventeen of the 28 received IPV only during hospitalization; the remaining 11 received IPV continuously at home after discharge. Two in the former group and three in the latter were hospitalized because of respiratory condition aggravation.
[Discussion]
Short-term IPV during hospitalization decreased sputum amount and SpO2 elevation. Long-term IPV during hospitalization and at home may prevent hospitalization caused by respiratory condition exacerbation.
