Abstract：Objective:To explore the effect of ultrasound evaluation combined with high-flow nasal cannula oxygenation(HFNCO)with heating and humidification on the success rate of extubation in children with invasive mechanical ventilation for more than 48 h in intensive care unit(ICU).Methods:Sixty children who received invasive mechanical ventilation treatment for more than 48 h in ICU of our hospital from November 2022 to November 2023 were selected as the research subjects.According to the treatment methods after extubation,they were divided into control group and observation group,with 30 cases in each group.All children underwent pulmonary ultrasound evaluation.The control group received non-invasive ventilation oxygen therapy after extubation,while the observation group received HFNCO treatment after extubation and antiemetic treatment.The therapeutic effects of different treatment methods were compared.At the same time,the children were divided into two groups based on whether extubation was successful,and their ultrasound indicators were observed.Results:The arterial blood gas indicators in the observation group were better than those in the control group after extubation(P<0.05).The HR and RR of the observation group after extubation were better than those of the control group(P<0.05),while there was no significant difference in SPO2(P>0.05).The clinical indicators related to extubation in the observation group were superior to those in the control group(P<0.05).The incidence of respiratory failure and the rate of re-extubation within 48 h after extubation in the observation group were lower than those in the control group(P<0.05).There was a significant difference in the changes of diaphragm displacement between the failed and successful weaning groups after the start of the spontaneous breathing test under ultrasound observation(P<0.05).Conclusion:For children undergoing invasive mechanical ventilation treatment in ICU for more than 48 h,ultrasound evaluation can effectively assess the condition of children's diaphragm to determine the timing of weaning.
