摘要
目的：探讨常规湿化与未湿化中低流量（4L/min）鼻导管吸氧对患者呼吸道症状的影响是否有明显差异.方法：选择呼吸内科接受低流量、低浓度吸氧患者800人,按随机数字表将以上患者随机分成湿化组（400例）和非湿化组（400）,记录每组患者吸氧后的呼吸道症状、细菌检出情况及不适症状并行统计学分析.结果：两组持续中低流量鼻导管吸氧12h后,湿化组出现鼻咽干燥的患者共39例（9.75%）,未湿化组为52例（13.0%）,χ2=1.156,P〉0.05;两组持续中低流量鼻导管吸氧24h后,湿化组出现鼻咽干燥的患者共71例（17.75%）,未湿化组为103例（25.75%）,χ2=0.274,P〉0.05;说明两种不同的吸氧方式对患者呼吸道影响差异无统计学意义（P〈0.05）.两种中低流量鼻导管吸氧患者应用不同时间的细菌检出率比较,P〈0.05.结论：中低流量鼻导管吸氧无需常规湿化.
Objective：To investigate the conventional wet and not wet in the low flow （4L/min）nasal oxygen catheter in patients with respiratory symptoms impact on whether a significant difference.Methods：Respiratory Medicine to accept low-flow.low concentrations of oxygen were 800 people,according to the random number table above were randomly divided into the wet group （400 cases） and non-wetting group （400）,recorded after each patient oxygen respiratory symptoms,and symptoms of bacterial detection in parallel statistical analysis.Results：There were continued in the low-flow nasal cannula oxygen for 12h,dry and wet group of patients with nasopharyngeal there were 39 cases （9.75%）.not wet group 52 cases （13.0%）, x 2=1.156,P〉0.05;two continuous low flow nasal oxygen catheter after 24h.dry and wet group of patients with nasopharyngeal there were 71 patients （17.75%）,not wet group 103 cases （25.75%）, x 2 =0.274,P〉0.05;illustrate two different ways of oxygen effects on the respiratory tract was no significant difference （P〈0.05）.Two kinds of low-flow nasal cannula oxygen patients the detection rate of bacteria at different times more.P〈0.05.Conelusion： The low-flow nasal cannula oxygen without conventional wet.
