膈肌超声评估机械通气患者撤机的临床应用与研究进展
Clinical application and research progress of diaphragmatic ultrasound in assessing weaning from mechanical ventilation
摘要
Abstract
Mechanical ventilation is a common respiratory support modality in the clinical management of respiratory failure,primarily aimed at improving oxygen supply and demand,reducing carbon dioxide retention,and reopening collapsed alveoli to restore lung ventilation and gas exchange function.In the ICU,most patients require more than 24 hours of mechanical ventilation support.However,mechanical ventilation is an invasive procedure,and from the moment it is initiated,clinicians must consider two challenges in the weaning process:one is unnecessarily prolonging mechanical ventilation duration,and the other is premature weaning.Both are associated with increased morbidity and mortality risks.Therefore,reducing patient dependence on the ventilator and performing precise assessments of diaphragmatic function can help increase the success rate of weaning and improve long-term patient outcomes.Traditional weaning indicators have shown insufficient sensitivity and specificity,highlighting the need for additional metrics to enhance the robustness of clinical decision-making.As the primary respiratory muscle,the diaphragm can be assessed using safe and portable ultrasound technology,allowing for the rapid evaluation and visualization of diaphragmatic function through thickness changes and displacement analysis at specific time points during mechanical ventilation.This approach helps achieve effective weaning outcomes.关键词
