摘　　要：目的探讨不同封管液对经外周留置的中心静脉导管输注20％甘露醇的影响。方法将99例颅内肿瘤患者按人院顺序分为3组，每组33例。A组用肝素钠盐水10ml正压封管；B组用0．9％生理盐水10ml脉冲式冲管，肝素钠盐水10m1正压封管；C组用0．9％生理盐水≥20ml脉冲式冲管，肝素钠盐水10m1正压封管。结果A组导管堵管率为51．5％，B组为24．6％，C组为6．1％。C组导管堵管率显著低于A组、B组（P〈0．05或0．01），B组显著低于A组（P〈0．05）。结论对经外周留置的中心静脉导管置管长期输注20％甘露醇完毕后用≥20ml生理盐水脉冲式冲管，肝素钠盐水正压封管，可有效降低导管堵管率。Objective To explore the influences of different tube sealing solutions on infused 20% mannitol via a peripherally inserted central catheter （PICC）. Methods Ninety-nine in-tracranial neoplasms patients were assigned to three groups oI 66 ones eacn according to admission order.Group A was locked using heparin sodium ＋10 ml normal saline; group B was flushed using 10 ml 0.9% normal saline and locked using heparin sodium ＋10 ml normal saline; group C was flushed using ~ 20 ml 0.9% normal saline and locked using heparin sodium ＋10 ml normal saline. Results Catheter obstruc-ting rate was 51.5% in group A, 24.6% B and 6.1% C, that significantly lower in C than in A and B （P〈0.05 or 0.01）, so was that in B than in A （P〈0.05）. Conclusion PICC flushed using ≥20 ml normal saline after long-term 20% mannitol infusion and locked using heparin sodium ＋ normal saline could effectively lower catheter obstructing rate.
