目的探讨经外周静脉穿刺的中心静脉置管(PICC)在慢性呼吸衰竭患者临床应用的效果,为临床急救的静脉输液方案提供依据。方法选择慢性呼吸衰竭患者100例,随机抽取30例为PICC组,70例为浅静脉穿刺对照组,比较两组静脉输液日均补液治疗时间(h/d)、不良反应的发生率和急救药物使用情况。结果两组患者在日平均补液治疗时间无明显差异(P>0.05);PICC组不良事件发生率为10%,对照组不良事件发生率为61.4%,明显高于PICC组(P<0.05);PICC组患者对静脉营养和血液制品方面的使用率明显高于对照组(P<0.05),在使用血管活性药物方面无明显差异(P>0.05),急救药物用药及时性及连续性方面比较,PICC组抢救次数为20人次,平均抢救及时用药时间为2.50±0.83min,对照组抢救次数为27人次,平均抢救及时用药时间为6.19±1.27min,PICC组用药及时性明显高于对照组。结论 PICC置管能够有效降低穿刺次数,保证补液治疗的连续性,提高特殊药物的使用安全性,有效降低静脉输液不良事件的发生率,同时还能够保证抢救时用药的及时性。
Objective To investigate the clinical effect of peripheral venous catheterization (PICC) in patients with chronic respiratory failure and provide basis for clinical emergency IVF. Methods A total of 100 patients with chronic respiratory failure were enrolled. 30 patients were randomly selected as PICC group and 70 as superficial vein puncture control group. The average daily rehydration time (h / d), the incidence of adverse reactions, Usage. Results There was no significant difference between the two groups in the average rehydration treatment time (P> 0.05). The incidence of adverse events in PICC group was 10% and that in control group was 61.4%, significantly higher than that in PICC group (P <0.05). The use rate of intravenous nutrition and blood products in PICC group was significantly higher than that in control group (P <0.05), there was no significant difference in the use of vasoactive drugs (P> 0.05), the timeliness and continuity of emergency medication were compared, PICC group rescues for 20 times, the average time for rescue is 2.50 ± 0.83min, the number of rescue in control group is 27, the average time for rescue and treatment is 6.19 ± 1.27min, the timeliness of PICC group is obviously higher than that of control group. Conclusion PICC catheter can effectively reduce the number of punctures, to ensure the continuity of rehydration therapy, improve the safety of special drugs, effectively reduce the incidence of adverse events of intravenous infusion, but also can ensure the timeliness of medication when saving.
