Abstract:
Objective To investigate the characteristics of lung ultrasound images in critical care postoperative patients using BLUE-plus protocol . Methods Two hundred and twenty-two patients who were performed lung ultrasound measurements according to the BLUE-plus protocol within 24 hours admitted to the Department of critical care were included in this study . Data was collected and retrospectively analyzed to compare the proportion of different lung ultrasound signs at different speculate regions ,and to compare the lung ultrasound characteristics of patients undergo different surgeries . Results Excluding A lines ,the most common abnormal lung ultrasound signs at the diaphragmatic points were B7 lines (13 .06％ ) ,and the most common abnormal lung ultrasound signs at the posterior blue points were C signs (28 .60％ ) . The rate of C signs was significantly higher in post spinal cord surgery patients than those in other groups ( P =0 .032) . The rate of B3 lines was significantly higher at bilateral PLAPS points in oxygenation index 100-200 group compared with that in oxygenation index>300 group ( P =0 .011) . The rate of C signs was significantly higher at the left posterior blue point in oxygenation index 200-300 group , and at bilateral posterior blue point in oxygenation index 100-200 and <100 groups compared with those in oxygenation index >300 group ( P =0 .011 , P <0 .001 and P =0 .002) . The rate of pleural effusion was significantly higher at the right posterior blue point in oxygenation index 200 -300 group ,and at bilateral posterior blue point in oxygenation index 100 -200 group compared with those in oxygenation index >300 group ( P = 0 .001 , P < 0 .001 ) . Conclusions Screen with the BLUE-plus protocol can help to find abnormal signs including B3 lines ,B7 lines ,C signs and pleural effusion ,therefore instructs individualized treatment for postoperative patients . Pulmonary edema ,lung consolidation and pleural effusion are three main reasons responsible for hypoxemia in postoperative patients . Intensivists should avoid fluid overload , strengthen airway management ,postural therapy and encourage early mobility in postoperative patients .
