We describe a case series constituting the first clinical trial by intravenous (IV) team nurses using the sonic flashlight (SF) for ultrasound guidance of peripherally inserted central catheter (PICC) placement.
Two IV team nurses with more than 10 years of experience with placing PICCs and 3 to 6 years of experience with ultrasound attempted to place PICCs under ultrasound guidance in patients requiring long-term IV access. One of two methods of ultrasound guidance was used: conventional ultrasound (CUS; 60 patients) or a new device called the SF (44 patients). The number of needle punctures required to gain IV access was recorded for each patient.
In both methods, 87% of the cases resulted in successful venous access on the first attempt. The average number of needle sticks per patient was 1.18 for SF-guided procedures compared with 1.20 for CUS-guided procedures. No significant difference was found in the distribution of the number of attempts between the two methods. Anecdotal comments by the nurses indicated the comparative ease of use of the SF display, although the relatively small scale of the SF image compared with the CUS image was also noted.
We have shown that the SF is a safe and effective device for guidance of PICC placement in the hands of experienced IV team nurses. The advantage of placing the ultrasound image at its actual location must be balanced against the relatively small scale of the SF image.
我们描述了一个病例系列,这是静脉输液团队护士首次使用声波手电筒(SF)进行外周静脉穿刺中心静脉导管(PICC)置入超声引导的临床试验。
两名有超过10年PICC置入经验且有3至6年超声经验的静脉输液团队护士,尝试在需要长期静脉通路的患者中,在超声引导下置入PICC。使用了两种超声引导方法之一:传统超声(CUS;60例患者)或一种名为SF的新设备(44例患者)。记录每位患者获得静脉通路所需的穿刺次数。
在两种方法中,87%的病例首次尝试即成功建立静脉通路。SF引导操作中每位患者的平均穿刺次数为1.18次,而CUS引导操作中为1.20次。两种方法之间的尝试次数分布没有显著差异。护士们的轶事评论表明,SF显示屏相对易于使用,不过也指出与CUS图像相比,SF图像的尺寸相对较小。
我们已经表明,对于经验丰富的静脉输液团队护士而言,SF是一种安全有效的PICC置入引导设备。将超声图像置于实际位置的优势必须与SF图像相对较小的尺寸相权衡。
