Abstract

Background: While bubble continuous positive airway pressure (bCPAP) is commonly used in low- and middle-income countries (LMIC) to support neonates with respiratory distress, there are limited non-invasive support options for non-neonatal children. Aim: To demonstrate safety of a new device designed to support children during respiratory distress in LMIC. Methods: A paediatric bCPAP device was designed called SEAL-bCPAP (Simplified Ear-plug Adapted-bCPAP). SEAL-bCPAP is constructed from inexpensive, easily obtainable materials. The nasal prong interface was modified from previously described neonatal bCPAP set-ups using commercial ear-plug material to improve nasal seal. A prospective interventional study was conducted to evaluate safety in children with respiratory distress treated with SEAL-bCPAP. Patients aged 30 days to 5 years presenting to a hospital in northern Uganda from July 2015 to June 2016 were screened. Those with moderate–severe respiratory distress and/or hypoxia despite nasal cannula oxygen were eligible for study. Enrolled patients were supported with SEAL-bCPAP until respiratory improvement or death. Complications attributable to SEAL-bCPAP were recorded. Clinical outcomes were compared with historical control pre-trial data. Results: Eighty-three of 87 enrolled patients were included in the final analysis. No patients had significant SEAL-bCPAP complications. Five patients had mild complications which resolved (four with nasal irritation and one with abdominal distention). Trial patients had significant (p < 0.0001) improvement in their TAL score, respiratory rate and O2sat after 2 h of SEAL-bCPAP. Fifty-two of 64 patients (62.7%) with severe illness at Time1 did not have severe illness at Time2 (after 2 h of SEAL-bCPAP) (p < 0.0001). Unadjusted mortality rates were 12.2% (6/49) and 9.6% (8/83), respectively, for pre-trial (historical control) and trial patients (p = 0.64); the study was not powered to show efficacy. Conclusions: The SEAL-bCPAP device is safe for treatment of respiratory distress in non-neonatal children in LMIC. There is a trend toward decreased mortality that should be evaluated with adequately powered clinical trials.
