摘要
目的研究吸痰负压对颅脑外伤后气管切开患者血氧饱和度(SPO2)的影响。方法根据患者痰液粘稠度不同,分别选择13.3 kPa、23.9 kPa、33.3 kPa的吸痰负压。观察吸痰前,吸痰后1 min、3 min5、min患者血氧饱和度(SPO2)。结果吸痰前后各时相SPO2不同,采用配对t检验,提示吸痰后1 min和吸痰后5 min SPO2与吸痰前差异有显著意义(P<0.05),而吸痰后3 min SPO2与吸痰前差异无显著意义。不同负压下吸痰前后患者的SPO2差异有显著意义P<(0.05)。结论吸痰负压越大,对SPO2影响越大。吸痰前后增加吸氧流量,可明显缩短SPO2变化时间。
Objective To compare the effect of different negative suction pressure on SPO2 for traumatic brain injury patients with tracheotomy. Method 13.3Kpa, 23.9Kpa,33.3Kpa suction pressure were used respectively to patients with tracheotomy depend on the viscidity of the sputum. Compare patients' SPO2 before suction and 1 min, 3 min and 5 min after suction. Result SPO2 differed from time to time after suction. There is significant difference of SPOz in the aspiration of sputum at 1 min and 5 min by pair t checkout(P〈0.05) ,and there is no difference of SPO2 after 3 min compared to that of het'ore aspiration of sputum. Patients' SPOz differed from different suction pressure (P〈0.05). Conclusion The higher'Pressure applied led to greater effect on SPO2 during suction. We can shorten the frustration of SPO2 obviously by increasing oxygen flow supply.
