The aim of this study was to determine the effective biomechanical technique for suctioning phlegm.
A novel tracheal suctioning simulator combined with a motion capture system was used to calculate the amount of simulated phlegm suctioned and the biomechanical parameters of the associated suctioning manoeuvre. A laboratory study, including 12 nurses with > 3 years of suctioning experience and 12 nursing students without any clinical suctioning experience, was conducted. The amount of phlegm suctioned, the maximum length of catheter insertion, and the biomechanical parameters of hand movement were calculated.
The mean amount of phlegm suctioned per second was significantly larger in the experienced group than in the non-experienced group. The amount of phlegm suctioned correlated positively with the length of the vertical path of motion of the wrist and forearm, and with the angular velocity of thumb rotation in both the groups.
Greater vertical motion of the wrist and thumb rotation improved the effectiveness of phlegm suctioning and prevented the need for deep suctioning, which is unsafe.
本研究旨在确定吸痰的有效生物力学技术。
使用一种结合了动作捕捉系统的新型气管吸痰模拟器来计算模拟吸痰量以及相关吸痰操作的生物力学参数。开展了一项实验室研究，纳入12名具有超过3年吸痰经验的护士和12名无任何临床吸痰经验的护生。计算了吸痰量、导管插入的最大长度以及手部运动的生物力学参数。
经验丰富组每秒平均吸痰量显著高于无经验组。两组的吸痰量均与手腕和前臂垂直运动路径的长度以及拇指旋转角速度呈正相关。
更大幅度的手腕垂直运动和拇指旋转提高了吸痰效果，避免了不安全的深部吸痰需求。
