OBJECTIVES: To investigate the application of lung ultrasound (US) in the evaluation and implementation of @entity133 maneuvers in @entity649 ( @entity649 ). METHODS: Twelve @entity95 with saline lavage-induced @entity651 were randomly divided into 2 groups: one with @entity133 guided by lung US and the other with @entity133 guided by maximal oxygenation. Recruitment maneuvers were applied according to a stepwise incremental positive end-expiratory pressure method in both groups. In the oxygenation group, a sum of the partial pressures of @entity26 and @entity544 exceeding 400 mm Hg was used to define adequate recruitment. In the lung US group, a new protocol for reaeration in US-guided lung recruitment was used to guide treatment. Evaluation by lung US, respiratory mechanical parameters, the Smith pathologic score (Crit Care Med 1997; 25:1888-1897), and wet-to-dry ratio were compared between the groups. RESULTS: Opening pressure was significantly higher in the lung US group (mean    SD, 23.4    3.4 cm @entity4358 ) than the oxygenation group (18.7    2.1 cm @entity4358 ; P < .05). The reaeration score in the lung US group significantly increased during @entity133 (6.5    1.6 points at baseline versus 13.8    3.0 points after completion; P < .05). Lung compliance, dead space shunts, the Smith pathologic score, and tissue wet-to-dry ratio, however, were not significantly different between the groups. CONCLUSIONS: Lung US is an effective means of evaluating and guiding @entity133 in @entity649 . Compared with the maximal oxygenation-guided method, the protocol for reaeration in US-guided lung recruitment achieved a higher opening pressure, resulted in greater improvements in lung aeration, and substantially reduced lung heterogeneity in @entity649 .
