Evidence is insufficient on the effect of tunnel lengths on tunneled peripherally inserted central catheter (PICC) placement in adult patients with cancer.
The primary objective was to explore whether there is an optimal PICC tunnel length to reduce the risk of PICC-related complications. The secondary objective was to compare patients' pain and comfort levels during catheter placement with different tunnel lengths.
Two hundred patients were randomly assigned to groups based on PICC tunnel length. Data collected included baseline characteristics, catheter-related characteristics, PICC-related complications, and patients' pain and comfort levels.
Patients with 4 cm, 5 cm, and 6 cm PICC tunnel lengths had a longer catheter dwell time and fewer PICC-related complications. No significant differences were found among all groups regarding patients' pain and comfort levels. The results suggest that a tunneled PICC is safe and effective. A tunnel length longer than 4 cm is recommended for tunneled PICC placement.
关于隧道长度对癌症成人患者经外周静脉穿刺中心静脉置管（PICC）置管的影响，证据尚不充分。
主要目的是探讨是否存在最佳的 PICC 隧道长度，以降低 PICC 相关并发症的风险。次要目的是比较不同隧道长度下患者在置管过程中的疼痛和舒适度水平。
将 200 名患者随机分配到基于 PICC 隧道长度的组中。收集的数据包括基线特征、导管相关特征、PICC 相关并发症以及患者的疼痛和舒适度水平。
隧道长度为 4cm、5cm 和 6cm 的患者的导管留置时间更长，PICC 相关并发症更少。所有组在患者的疼痛和舒适度水平方面均无显著差异。结果表明，隧道式 PICC 是安全有效的。建议对隧道式 PICC 置管采用长于 4cm 的隧道长度。
