This study compared patho-physical indexes, respiratory mechanics, circulatory parameters and lung injury scores of acute lung injury (ALI) induced by steam inhalation injury in a New Zealand rabbit model with different ventilatory strategies: a control group which consisted of lower tidal volume (VT 6 ml/kg) and high positive end-expiratory pressure (PEEP) (9 cmH(2)O); treatment group which was high frequency oscillatory ventilation (HFOV). Eighteen rabbits were anaesthetized, sedated, neuromuscular-blocked and ventilated with above two modes at our animal laboratory of burn center. After induction of acute lung injury by steam inhalation, animals were randomly assigned to receive either conventional mechanical ventilation (CMV) or high frequency oscillatory ventilation and were grouped as CMV and HFOV group. As a result, HFOV attenuated the decrease in oxygenation and pulmonary compliance, alleviated lung tissue damage and inflammatory response. Therefore, HFOV may be a preferable option for treatment of acute lung injury induced by steam inhalation injury.

D011897 Random Allocation A process involving chance used in therapeutic trials or other research endeavor for allocating experimental subjects, human or animal, between treatment and control groups, or among treatment groups. It may also apply to experiments on inanimate objects. Randomization,Allocation, Random
D012121 Respiration, Artificial Any method of artificial breathing that employs mechanical or non-mechanical means to force the air into and out of the lungs. Artificial respiration or ventilation is used in individuals who have stopped breathing or have RESPIRATORY INSUFFICIENCY to increase their intake of oxygen (O2) and excretion of carbon dioxide (CO2).

D006612 High-Frequency Ventilation Ventilatory support system using frequencies from 60-900 cycles/min or more. Three types of systems have been distinguished on the basis of rates, volumes, and the system used. They are high frequency positive-pressure ventilation (HFPPV); HIGH-FREQUENCY JET VENTILATION; (HFJV); and high-frequency oscillation (HFO).
