【摘要】 目的探讨递减负压吸痰法在脑卒中气管切开术后1周患者中的应用方法与效果。方法将104例脑卒中气管切开后1周的患者按住院或转入单双日分为研究组和对照组各52例。研究组采用递减负压吸痰法,即从上往下抽吸,负压依次为-33~-36kPa,-27~-30 kPa,-22~-26 kPa。对照组采用常规吸痰法,即从下往上抽吸,压力-20~-40 kPa。结果两组在吸痰后1min2、min5、min的SpO2,气道黏膜损伤情况,痰液吸净时间比较,差异有统计学意义(P<0.05,P<0.01)。结论递减负压吸痰较常规吸痰能明显减少吸痰引起的气道黏膜损伤及SpO2的变化,有助于在较短时间内吸净痰液。更多还原

【Abstract】 Objective To study the application and effect of descending negative pressure suctioning on stroke patients one week after tracheotomy.Methods A total of 104 stroke patients given tracheotomy one week later were equally divided into an experimental group and a control group according to odd or even admission date.The experimental group applied descending negative pressure suctioning,namely researchers′ aspirating the sputum from upward to downward,with the negative pressure being-33——36 kPa,-27——30 kPa,and-22——26 kPa in order.Conversely,the control group adopted routine suctioning method with opposite direction,the pressure being-20——40 kPa.Results The results of SpO2 at 1 min,2 min and 5 min after suctioning,the severity of airway mucosa injury,and the length of sputum clearance,showed significant differences between the 2 groups(P<0.05,P<0.01).Conclusion With respect to routine method,descending negative pressure suctioning could remarkably reduce suctioning-induced mucosa injury and avoid fluctuation of SpO2,which promotes higher suctioning efficiency.更多还原
