【摘要】 目的探讨行气管插管的老年患者吸痰时的安全有效吸痰深度。方法将60例肺部感染行气管插管的老年患者随机分为浅吸痰组和深吸痰组,各30例。浅吸痰组吸痰管深入气道超过气管插管头端2 cm;深吸痰组吸痰管深入气道遇阻力后向上2cm。观察2组患者吸痰前后心率、血压、呼吸频率、血氧饱和度的变化,同时对比2组吸痰间隔时间、吸痰次数、气道损伤出血情况。结果2组患者吸痰后心率、收缩压、呼吸频率的变化比较差异无统计学意义(P>0.05);吸痰后,患者血氧饱和度增幅深吸痰组显著高于浅吸痰组(P<0.05);与浅吸痰组相比,深吸痰组吸痰间隔时间较长,吸痰次数较少,差异均具有统计学意义(P<0.05)。结论肺部感染行气管插管老年患者吸痰时,浅层吸痰效果并不优于深层吸痰,仍需进一步研究确定有效的吸痰深度。更多还原

【Abstract】 Objective To investigate the effective and safe depth of endotracheal suction for elderly patients with trachea intubation.Methods Sixty elderly patients with pulmonary infection underwent mechanical ventilation were randomly divided into shallow suction group(tracheal suction tube over the cannula 2 cm) and depth suction group(tracheal suction tube into airway 2 cm away before insertion resisted),with 30 cases respectively.The changes in heart rate,systolic pressure,respiratory rate and oxygen saturation was measured before and after suction.Comparison was also made on interval time of suction,suction frequence and airway injury between two groups.Results There was no significant difference in changes of heart rate,systolic pressure and respiratory between two groups(P>0.05).After endotracheal suction,there was a significant difference in growth of oxygen saturation between two groups(P < 0.05).Compared with shallow suction group,depth suction group has longer interval time and less frequency(P<0.05).Conclusion There was no significant difference between shallow and depth endotraheal suction for elderly patients with trachea intubation,well- designed studies is wanted to explore the effective depth of endotraheal cannula.更多还原
