ObjectiveTo evaluate the clinical result of lateral position ventilation and prone position ventilation in acute lung injury/acute respiratory distress syndrome (ALI/ARDS) patients.MethodsTwenty-four patients were allocated to two groups, with one group (n = 13) receiving lateral position ventilation after April 2002, and the other (n = 11) received prone position ventilation before March 2002. Respiratory and circulatory indices were monitored after position changes and compared between the two groups.ResultsOne hour after position change PaO(2) was elevated in both groups; in the lateral position group from (103 +/- 12) mm Hg to (126 +/- 13) mm Hg (P < 0.01), and in the prone position group from (87 +/- 19) mm Hg to (119 +/- 15) mm Hg (P < 0.01). If a 10 mm Hg increase was regarded as the standard of treatment effectiveness, then the effective rate in the lateral position group was 61.5% and in the prone position group was 63.6%, the difference being not significant.ConclusionAs auxiliary means in the treatment of ALI/ARDS, lateral position and prone position ventilation showed similar effects, but the lateral position was more convenient for practice and medical care, thus needs further investigation.
