Abstract:
To evaluate the safety, feasibility and efficacy of a novel non‐invasive ventilation (NIV) technique—pharyngeal oxygen with nose‐closure and abdominal‐compression (PhO 2 ‐NC‐AC) — to aid pediatric flexible bronchoscopy (FB). Design A prospective 1 year study of patients who received FB. A basic PhO 2 flow (0.5–1.0 L/kg/min, maximal 5.0 L/min) was routinely applied. Active NIV was initiated when the heart rate dropped 〈 80 beats/min or desaturation was 〈 80% for 〉 10 sec. It was performed as follows: NC 1 sec for inspiration then released, followed by AC 1 sec for active expiration at a rate of 20–30 cycles/min until vital signs returned to acceptable levels for 〉 10 sec. When the patients were stable, supplementary NIV was optionally given. Cardiopulmonary parameters were collected and analyzed. Measurements and Main Results Three hundred thirty‐seven FBs, including 188 therapeutic, were conducted in 286 patients with a mean age of 18.3 months (±14.4, 10 min to 12 years) and a mean body weight of 13.5 kg (±6.7, 0.5–35 kg). Three hundred thirty‐three active NIVs were executed with a mean duration of 87.8 sec (±40.4, 28–190 sec). A significantly longer FB duration (33.2 ± 16.7 min vs. 7.2 ± 2.8 min, P 〈 0.001) and a higher application rate of active NIV (1.44/FB vs. 0.42/FB) were noted in the therapeutic compared to the diagnostic group. Vital signs and blood gases (35 cases) improved rapidly and returned to baseline within 3 min. All FBs were safely and successfully completed without significant complications. Conclusions PhO 2 ‐NC‐AC is a simple, safe and effective NIV technique for respiratory support and rescue during various pediatric FB procedures.
