目的探讨在老年患者中采用自行设计的改良面罩在纤支镜吸痰中的效果。方法40例需要纤支镜吸痰治疗的患者共行纤支镜吸痰74次,随机分为两组:鼻导管给氧组36次和面罩给氧组38次,对比两组在纤维支气管镜吸痰过程中SpO2和ST段改变及心律失常发生的情况。结果鼻导管给氧组与面罩给氧组相比,在最低SpO2、ST段改变及心律失常发生方面差异有统计意义(P<0.05)。结论纤支镜吸痰时应用改良面罩给氧可明显提高患者SpO2水平、减少心肌缺氧及心律失常的发生。应用改良面罩给氧行纤支镜吸痰对老年患者是一种简便而行之有效的方法。
Objective To investigate the effect of self-designed modified face mask on sputum aspiration in elderly patients. Methods Forty patients undergoing bronchoscopy were randomly divided into two groups: 36 for nasal catheterization group and 38 for oxygen mask group. Thirty patients undergoing bronchofibroscopy SpO2 and ST segment changes during sputum aspiration and arrhythmia. Results There were significant differences in minimum SpO2, ST segment changes and arrhythmia between nasal catheter oxygenation group and oxygen mask group (P <0.05). Conclusion The application of modified face mask to sputum aspiration for bronchofibroscopy can significantly improve the level of SpO2 and reduce the occurrence of myocardial hypoxia and arrhythmia. Application of modified mask oxygen line fiberoptic bronchoscopy sputum suction is an easy and effective method for elderly patients.
