Long-term central venous catheter (CVC) insertion in dialysis patients is an accepted method of hemodialysis. The appropriate CVC tip placement may reduce both early and late complications related to catheter and increase patency rate. This study aimed to evaluate a new, simple, and feasible method based on surface anatomy for the proper placement of tunneled CVC in the left internal jugular vein for hemodialysis or chemotherapy.
The study was carried out as a quasi-experimental model at Saint Al-Zahra Education Hospital in 2016. A total of forty patients with an indication of left-sided (upper) long-term CVC insertion were enrolled. The length of catheter to be inserted in the left internal jugular vein was considered as the sum of distance from the insertion point of the needle up to sternal notch plus the total distance between the left and right sternoclavicular joint and half-length of the sternum. The right atrium (RA) or superior vena cava-RA junction was the correct region for inserting the catheter tip. The collected data were analyzed using Fisher's exact test and -test using SPSS (version 22).
The patients were 63.75 ± 17.96 years of age, weighed 67.33 ± 13.20 kg, and height of 166.92 ± 8.99 cm. Catheters were inserted successfully in 95% of patients ( = 38). No significant relationship was found between the success of new method and age, gender, height, weight, body mass index, and sternum half-length plus the distance between the right and left sternoclavicular joint.
"The mid - sternal length plus sternoclavicular joints spacing" as a new formula (based on anatomical landmarks) was found practical and safe and could easily be used among adult patients who undergo tunneled CVC in the left internal jugular vein.
在透析患者中长期置入中心静脉导管(CVC)是一种公认的血液透析方法。合适的CVC尖端位置可减少与导管相关的早期和晚期并发症,并提高通畅率。本研究旨在评估一种基于体表解剖学的新的、简单可行的方法,用于在左侧颈内静脉正确置入带隧道的CVC以进行血液透析或化疗。
本研究于2016年在圣阿尔扎赫拉教育医院以准实验模型进行。共纳入40例有左侧(上部)长期CVC置入指征的患者。将插入左侧颈内静脉的导管长度视为从进针点到胸骨切迹的距离加上左右胸锁关节之间的总距离再加上胸骨半长。右心房(RA)或上腔静脉-RA交界处是插入导管尖端的正确区域。使用SPSS(22版)的Fisher精确检验和t检验对收集的数据进行分析。
患者年龄为63.75±17.96岁,体重为67.33±13.20 kg,身高为166.92±8.99 cm。95%的患者(n = 38)成功插入导管。新方法的成功率与年龄、性别、身高、体重、体重指数以及胸骨半长加上左右胸锁关节之间的距离之间未发现显著关系。
“胸骨长度加胸锁关节间距”作为一种新的公式(基于解剖标志)被发现实用且安全,可轻松应用于在左侧颈内静脉接受带隧道CVC置入的成年患者。
