Analysis on the application effect of spontaneous breathing trial combined with optimized nursing in weaning of mechanically ventilated patients
自主呼吸实验联合优化护理在机械通气患者试脱机中的应用效果分析

摘要

目的 探讨自主呼吸实验联合优化护理干预模式，在重症机械通气患者临床试脱机中的实际应用价值与临床效果，为临床安全脱机提供参考依据。方法 本研究纳入2024年1月至2025年12月于本院接受机械通气治疗的80例患者作为研究对象，采用随机数字分配法将所有受试患者均分两组，每组各40例。其中对照组予以临床常规脱机护理模式开展照护工作，观察组实施自主呼吸实验联合全程精细化优化护理干预措施。比较两组脱机相关指标、脱机成功率及并发症发生率。结果 相较于对照组，观察组机械通气耗时与住院周期显著缩短，脱机成功占比提升，并发症发生占比明显降低，两组各项观测指标比较差异具有统计学意义（P＜0.05）。结论 自主呼吸实验联合优化护理应用于机械通气患者试脱机中，可缩短通气与住院时间，提升脱机成功率，减少并发症，临床应用价值显著。

Abstract

Objective To explore the practical application value and clinical effect of spontaneous breathing trial combined with optimized nursing intervention in the trial weaning of critically ill patients with mechanical ventilation, so as to provide reference for clinical safe weaning.
Methods A total of 80 patients receiving mechanical ventilation in our hospital from January 2024 to December 2025 were enrolled in this study. All subjects were equally divided into two groups by random number allocation method, with 40 cases in each group. The control group received conventional clinical weaning nursing, while the observation group received spontaneous breathing trial combined with whole- process refined optimized nursing intervention. The weaning- related indicators, weaning success rate and complication incidence were compared between the two groups.
Results Compared with the control group, the observation group presented significantly shorter mechanical ventilation duration and hospital stay, higher weaning success rate and lower complication incidence, and the differences in all observed indicators between the two groups were statistically significant (P＜0.05).
Conclusion   The application of spontaneous breathing trial combined with optimized nursing in trial weaning for mechanically ventilated patients can shorten ventilation and hospital stay, improve weaning success rate and reduce complications, which possesses prominent clinical application value.
