Prenatal sonographic markers of the outcome in fetuses with bronchopulmonary sequestration.

Purpose: To evaluate the prenatal sonographic predictive markers of the outcome in fetuses with bronchopulmonary sequestration (BPS).

Methods: BPS size and diameter of the feeding artery (FA) were measured prenatally and postnatally. Velocity of the FA and the left ventricular-modified myocardial performance index (LV mod-MPI) were also evaluated prenatally.

Sequential radiologic and functional pulmonary changes in patients with paraquat intoxication.

The sequential changes of paraquat-induced pulmonary damage were studied using high-resolution computed tomography (HRCT) and pulmonary function tests (PFTs) in long-term follow-up. Among the cohort of 27 patients who had ingested paraquat, the HRCT findings showed a normal (n = 14) and an abnormal group (n = 13). Increased paraquat ingestion in the abnormal group was associated with more rapid and severe pulmonary changes.

Morphometric effects of the recruitment maneuver on saline-lavaged canine lungs. A computed tomographic analysis.

Background: In the face of widespread use of lung-protective, low-volume ventilation in patients with acute lung injury, interest in the recruitment maneuver (RM) is growing. Little is known about lung-morphometric effects of the RM as compared with positive end-expiratory pressure (PEEP) titration (PT) without the RM.

Methods: RM was defined as a stepwise change in PEEP from baseline to 10, 20, 30, and 20 cm H(2)O every 30 s, after which PEEP was reset at the lower inflection point + 2 cm H(2)O.

Effect of alveolar recruitment maneuver in early acute respiratory distress syndrome according to antiderecruitment strategy, etiological category of diffuse lung injury, and body position of the patient.

Objective: To assess how the level of positive end-expiratory pressure (PEEP) (antiderecruitment strategy), etiological category of diffuse lung injury, and body position of the patient modify the effect of the alveolar recruitment maneuver (ARM) in acute respiratory distress syndrome (ARDS).

Design: Prospective clinical trial.

Setting: Medical intensive care unit at a tertiary hospital.
