Heated Humidified Oxygen Compared to Dry Oxygen Therapy in Children With Bronchiolitis

2015-04-17 12:08:22 | BioPortfolio

Summary

The purpose of this study is to compare heat and humidified oxygen with cold and dry oxygen in children with bronchiolitis.

The hypotheses are that heating and humidifying inspired low flow supplemental oxygen will optimize mucociliary function thereby, 1) improve oxygenation, 2) decrease work of breathing, and 3) decrease length of hospital stay.

Description

Bronchiolitis is the leading cause of acute respiratory illness and hospitalization in infants and young children. The mainstay of treatment is supportive care, which includes frequent nasal suctioning, intravenous fluid hydration, and supplemental oxygen for hypoxemia.

The airways normally heat and humidify inspired ambient air to core temperature amd 100% relative humidity at the carina. This environment, at core temperature, allows for optimal mucociliary clearance. Supplemental oxygen delivered via wall source is cold and dry, and does not reach core temperature and 100% humidity until some point distal to the carina, past the main bronchi. This presses on the lower respiratory tract to assist in heat and moisture exchange and thus decrease ciliary function. This, in combination with bronchiolitis, can impair mucociliary clearance.

Specific aim 1: Determine the effect of heated and humidified oxygen therapy on clinical improvement in children with bronchiolitis, based on Respiratory Distress Assessment Instrument (RDAI) and respiratory rate (RR).

Specific aim 2: Determine the effect of heated and humidified oxygen therapy on length of hospital stay and duration of supplemental oxygen requirement in children with bronchiolitis.

Medical and Biotech [MESH] Definitions

The rate at which oxygen is used by a tissue; microliters of oxygen STPD used per milligram of tissue per hour; the rate at which oxygen enters the blood from alveolar gas, equal in the steady state to the consumption of oxygen by tissue metabolism throughout the body. (Stedman, 25th ed, p346)

Inflammation of the BRONCHIOLES.

Stable oxygen atoms that have the same atomic number as the element oxygen, but differ in atomic weight. O-17 and 18 are stable oxygen isotopes.

Molecules or ions formed by the incomplete one-electron reduction of oxygen. These reactive oxygen intermediates include SINGLET OXYGEN; SUPEROXIDES; PEROXIDES; HYDROXYL RADICAL; and HYPOCHLOROUS ACID. They contribute to the microbicidal activity of PHAGOCYTES, regulation of signal transduction and gene expression, and the oxidative damage to NUCLEIC ACIDS; PROTEINS; and LIPIDS.

Unstable isotopes of oxygen that decay or disintegrate emitting radiation. O atoms with atomic weights 13, 14, 15, 19, and 20 are radioactive oxygen isotopes.
