The purpose of this study was to determine whether using a standard method of endotracheal suctioning, to ensure consistent use of available knowledge, had any impact on patient care. Using experimental study design, the results of two different methods of suctioning in a cardiovascular surgery intensive care unit were compared. One method was the suctioning procedure applied by the nurses working in the intensive care unit. The other one, standard suctioning procedure, was developed based on the related literature and applied to the patients assigned to the experimental group by the researcher herself. Mean arterial blood pressure (MAP), heart rate (HR), and arterial blood gases (ABGs) were measured before the procedure, immediately after, 5 and 15 minutes after the procedures for both control and experimental group. The majority of the nurses suctioning the control group did not evaluate the ABGs after endotracheal suctioning, none of these patients was given oxygen both before and after the suctioning, and suctioning took longer time than recommended. To compare the results of the two different methods, the values of MAP, HR, PO2 (arterial oxygenation), PCO2 (arterial carbondioxide), and HCO3- (hydrogen carbonate) 15 minutes after the procedure were used, and the differences between the two methods were statistically significant (P < 0.05).
本研究的目的是确定采用标准的气管内吸痰方法以确保对现有知识的一致应用是否对患者护理有任何影响。采用实验研究设计，比较了心血管外科重症监护病房中两种不同吸痰方法的效果。一种方法是重症监护病房护士采用的吸痰程序。另一种是标准吸痰程序，它是根据相关文献制定的，并由研究人员本人应用于分配到实验组的患者。在操作前、操作后即刻、操作后5分钟和15分钟分别测量了对照组和实验组的平均动脉血压（MAP）、心率（HR）和动脉血气（ABG）。吸痰对照组的大多数护士在气管内吸痰后未评估动脉血气，这些患者在吸痰前后均未吸氧，且吸痰时间比推荐时间长。为比较两种不同方法的效果，使用了操作后15分钟时的MAP、HR、PO2（动脉氧合）、PCO2（动脉二氧化碳）和HCO3-（碳酸氢盐）值，两种方法之间的差异具有统计学意义（P < 0.05）。
