Abstract
External chest compression (squeezing) is a technique to assist expiration. The effectiveness of squeezing on inhalation therapy in asymptomatic periods for asthmatic children was studied. Urinary DSCG excretion during 4 hours after DSCG inhalation using an ultrasonic nebulizer with and without squeezing was measured, since urinary excretion of DSCG parallels its lung deposition. The effect of squeezing on DSCG inhalation was not statistically significant. However, the urinary excretion of DSCG was increased 1.4-2.1 times with squeezing for three out of six cases. In a case of an eight-year-old girl, the urinary excretion of DSCG was not increased with squeezing; however, cough with sputa was induced. For two other cases, the effect of squeezing on inhalation therapy was not recognized. One of the two cases, a three-year-old boy, was not able to inspire deeply due to the much compression on chest wall without synchronized breathing. The effectiveness of squeezing on inhalation therapy in asymptomatic periods was shown at least in some cases.
