Impact of neurophysiological respiratory facilitation techniques on arterial blood gas parameters in pediatric patients with bronchial pneumonia

Key Result

Neurophysiological respiratory facilitation techniques significantly improved post-treatment PaO2 to 77.36 mmHg compared to 62.33 mmHg with conventional therapy alone in pediatric bronchial pneumonia.

Key Points

To evaluate the impact of neurophysiological respiratory facilitation techniques on arterial blood gas parameters in pediatric patients with bronchial pneumonia.
Randomized control trial design
Sixty participants aged 1-4 years with bronchial pneumonia
Experimental group received neurophysiological techniques in addition to chest physiotherapy
Treatment administered twice daily for seven days
Arterial blood gases (PaO₂ and PaCO₂) were measured pre- and post-treatment.
Experimental group showed greater improvements in PaO₂ and PaCO₂ than control.
Post-treatment PaO₂ increased from 33.76 to 77.36 mmHg in the experimental group (p = 0.001).
Post-treatment PaCO₂ decreased from 53.29 to 38.36 mmHg in the experimental group (p = 0.005).

Structured PICO

Does the addition of neurophysiological respiratory facilitation techniques to conventional chest physiotherapy improve arterial blood gas parameters in pediatric patients with bronchial pneumonia?

Population

60 pediatric patients (ages 1-4 years) with bronchial pneumonia, presumed viral or bacterial etiology, oxygen saturation >85% on room air, heart rate 80-120 bpm, respiratory rate 20-30 bpm. Excluded: convulsions, fever, fractures, tumors, hemorrhagic conditions, recent neurosurgery, severe anemia, or congenital cardiac anomalies.

Intervention

Conventional chest physiotherapy plus neurophysiological facilitation techniques (peri-oral pressure, intercostal stretch, anterior stretch-lifting of the posterior basal area, and abdominal co-contraction). Each technique performed with 5 repetitions, 5-second holds, and 5-second rest intervals. Administered three times daily (abstract states twice daily) for 7 consecutive days, 20 minutes per session.

Comparator

Conventional chest physiotherapy alone (modified postural drainage, percussion, and positioning), administered three times daily for 7 consecutive days, 20 minutes per session.

Outcome

Arterial blood gas parameters (PaO2 and PaCO2) measured before and after 7 days of treatment.surrogate

Neurophysiological respiratory facilitation techniques combined with conventional chest physiotherapy significantly improve oxygenation and reduce carbon dioxide levels in pediatric patients with bronchial pneumonia.

Main Result

Absolute Event Rate: 77.36% vs 62.33%

p-value: p=0.001

Limitations

Single-center design
Relatively small sample size
Restricted age range of 1-4 years
Short duration of seven days
Lack of blinding among physiotherapists administering the interventions

Abstract

Bronchial pneumonia remains a significant cause of morbidity, particularly in pediatric populations. This study aimed to evaluate the impact of neurophysiological respiratory facilitation techniques on arterial blood gas parameters in pediatric patients with bronchial pneumonia. Sixty pediatric patients (ages 1–4 years) with bronchial pneumonia were randomly assigned to two groups. The control group (n = 30) received conventional chest physiotherapy, while the experimental group (n = 30) received additional neurophysiological facilitation techniques, including peri-oral pressure, intercostal stretch, anterior stretch-lifting, and abdominal co-contraction. Treatment was administered twice daily for a period of seven days. Arterial blood gases (PaO₂ and PaCO₂) were measured before and after treatment. The experimental group demonstrated significantly greater improvements in arterial blood gas parameters compared to the control group. Post-treatment PaO₂ increased more substantially in the experimental group (33.76 ± 11.59 to 77.36 ± 12.34 mmHg) than in controls (35.32 ± 12.16 to 62.33 ± 18.00 mmHg; p = 0.001). Similarly, PaCO₂ decreased more markedly in the experimental group (53.29 ± 9.41 to 38.36 ± 3.75 mmHg) versus controls (51.57 ± 11.59 to 41.68 ± 4.95 mmHg; p = 0.005). Neurophysiological respiratory facilitation techniques, when combined with conventional chest physiotherapy, significantly improve arterial blood gas parameters in pediatric patients with bronchial pneumonia.
