Impact of Using a Novel Gastric Feeding Tube Adaptor on Patient's Comfort and Air Leaks During Non-invasive Mechanical Ventilation / Impacto del uso de un innovador adaptador para la sonda de alimentación gástrica en la comodidad y las fugas de aire durante la ventilación mecánica no invasiva

RESUMEN

INTRODUCTION: The presence of oral or naso-enteral probes during non-invasive mechanical ventilation (NIMV) increases the risk of leakage and patient discomfort. The objective of this study was to evaluate the effectiveness of a novel tube adapter for NIMV (TA-NIMV) in relation to leakage and comfort level. METHODS: A non-randomized quasi-experimental design was performed in an adult intensive care unit of a highly complex hospital, in which patients were their own controls. We included adult patients who required NIV with oronasal mask and who simultaneously had oral or naso-enteric tubes. The interventions were as follows every participant received two therapies, one with the TA-NIMV and one conventional therapy of NIMV (CT-NIMV). Comfort could be evaluated in 99 patients with a Glasgow Coma Scale of 15. The outcomes of interest was the average percentage of air leak and patient comfort during each intervention. RESULTS: 196 patients were included in the study during a 16-month period. The mean air leak percentage was 9.2% [standard deviation (SD), 7.7] during TA-NIMV and 32.5% (SD, 12.5) during CT-NIMV (p < 0.001). 84.9% reported being comfortable or very comfortable during TA-VMNI. 66.7% Uncomfortable or Very uncomfortable during CT-NIMV (p < 0.001). CONCLUSION: Higher comfort levels and lower air leakage volume percentages were achieved using the TA-NIMV than those achieved by CT-NIMV
