Abstract
Objective To investigate the application of ultrasound to quantify the diaphragmatic motor function of neonates and infants and the change of diaphragmatic motor in children with broncho-pulmonary dysplasia(BPD),and to evaluate the predictive value of diaphragmatic ultrasound for the results of mechanical ventilation weaning of BPD children.Methods A total of 23 children with mechanical ventilation of BPD in NICU,PICU and SNICU in Guangzhou Women and Children's Medical Center were included from August 2022 to August 2023.The children were divided into a successful group(n=18)and a failed group(n=5)according to whether they could breathe autonomically after clinical weaning.The basic clinical characteristics of the children were recorded.Meanwhile,23 newborns and infants in the same period were selected as the normal control group.Diaphragmatic motion(DM),diaphragmatic thickness at the end of inspiration(DTinsp),diaphragmatic thickness at the end of expiration(DTexp)and diaphragmatic thickening fraction(DTF)were measured by ultrasonography in all groups.The difference of diaphragmatic muscle movement between left and right sides in different groups was compared.Results The levels of DM in BPD group were significantly lower than those in control group before and after weaning(P<0.05).DTinsp,DTexp and DTF had no statistical significance compared with the control group(P>0.05).The levels of DM,DTinsp and DTF in the failed group were significantly lower than those in the successful group(P<0.05),but there was no significant difference in the DTexp group(P>0.05).Retrospective comparison before weaning:DM and DTF in the failed BPD group were lower than those in the successful BPD group,and the difference was statistically significant(P<0.05),there was no significant difference in DTexp and DTinsp between the two groups(P>0.05).Conclusion The changes of diaphragmatic motor function in children with BPD undergoing mechanical ventilation can be evaluated by bedside ultrasound,which has a good value in predicting the outcome of weaning from mechanical ventilation.关键词
