无创通气下纤维支气管镜检查危重患者32例临床观察

摘要

Objective To observe safety of non-invasive ventilation-assisted fiber bronchoscope examination for critical patients. Methods A total of 62 critical patients were divided by random number table into treatment group (n=32) and control group (n=30). The treatment group received non-invasive ventilation-assisted fiber bronchoscope examination, and the control group only received fiber bronchoscope examination with mask oxygen-inspiration. Dynamic changes of saturation of pulse oximetry (SpO2), heart rate (HR), respiratory rate (RR), and systolic blood pressure (SBP) were observed in the two groups. Results Comparing with those before operation, the treatment group had obviously increased SpO2 and HR, with statistically significant difference (P<0.01), increased SBP, with statistically significant difference (P<0.05), and stable RR without remarkable change (P>0.05). In the control group, its SpO2 was obviously decreased, with statistically significant difference(P<0.01), and HR, RR, SBP were increased, with statistically significant difference (P<0.01). Conclusion Implement of non-invasive ventilation-assisted fiber bronchoscope examination shows obviously increased SpO2. This method can improve safety and tolerance in patients, and it is worthy of clinical promotion and application.%目的：观察危重患者无创通气辅助下行纤维支气管镜检查的安全性。方法采用随机数字表法将62例危重患者分为治疗组(n=32)和对照组(n=30)。治疗组在无创通气辅助下行纤维支气管镜检查，对照组仅使用面罩吸氧行纤维支气管镜检查。观察两组患者的脉搏血氧饱和度(SpO2)、心率(HR)、呼吸频率(RR)、收缩压(SBP)等指标的动态变化。结果治疗组操作中 SpO2、HR 较操作前明显上升，差异有统计学意义(P<0.01)， SBP 较操作前升高，差异有统计学意义(P<0.05)，而 RR 无明显变化(P>0.05)。对照组操作中 SpO2较操作前有明显下降，差异有统计学意义(P<0.01)， HR、RR、SBP 较操作前明显升高，差异有统计学意义(P<0.01)。结论在无创通气辅助下，行纤维支气管镜检查过程中 SpO2较操作前明显上升，能明显提高患者的安全性和耐受性，值得临床推广使用。
