BACKGROUND Peripheral Intravenous cannula (IV) is the most common vascular access device used to administer medications with the exception of medication or fluid with high or low PH or hyperosmolarity which may cause severe damage to small veins. The insertion of a peripheral intravenous cannula in newborn infants can be difficult. Appropriate veins with sufficient capacity to insert a cannula become less available throughout the hospital stay. Once a peripheral intravenous cannula is inserted, it is desirable that its patency can be maintained as long as possible. This study was aimed to assess the lifespan and associated factors of peripheral intravenous cannula among infants admitted in public hospitals of Mekelle city, Tigray, Ethiopia, 2016. METHODS The method used was a prospective cohort study. 178 study subjects were recruited using systematic random sampling technique. The data was collected by structured questionairre and observational checklist. RESULTS More than half of infants (94) had a short cannula lifespan (below 30 h). Multivariable logistic regression analysis showed that Pediatric intensive care unit (PICU) [AOR = 6.93; 95% CI (1.56,30.71)], clinical experience (3-5 years) [AOR = 0.168; 95% CI (0.060-0.469)], insertion site (arm) [AOR = 0.126;95% CI (0.046-0.349)], reason for removal (dislodgement and complication) [AOR = 8.15; 95% CI (2.49,26.63) [AOR = 10.48;95% CI (3.08,35.65)], medication [AOR = 0.17;95% CI (0.37,0.784)], corticosteroids [0.164; 95% CI (0.034,0.793)] and blood transfusion [AOR = 0.12; 95% CI (0.028-0.509)] were the statistically significant variables associated with the lifespan of a peripheral intravenous cannula. CONCLUSIONS Untimely removal of peripheral intravenous cannulas was higher in infants and demographic. Cannulation and health care factors had significant effects on the lifespan of a peripheral intravenous cannula.

埃塞俄比亚提格雷，梅凯尔市公立医院收治的婴儿的外周静脉插管寿命及相关因素，2016年。

背景技术外周静脉插管（IV）是最常用的血管通路装置，除了可能引起小静脉严重损伤的高PH值或低PH值或高渗性的药物或液体外，用于给药。在新生婴儿中插入外围静脉插管可能很困难。在整个住院期间，足够有能力插入套管的适当静脉变得越来越少。一旦插入了外周静脉插管，就希望其通畅性能够保持尽可能长的时间。这项研究旨在评估2016年在埃塞俄比亚提格里市梅凯尔市公立医院收治的婴儿的寿命以及相关外周静脉插管的影响。方法该方法是一项前瞻性队列研究。使用系统随机抽样技术招募了178名研究对象。数据是通过结构化问卷和观察清单收集的。结果一半以上的婴儿（94岁）的插管寿命短（30小时以下）。多变量logistic回归分析表明，小儿重症监护病房（PICU）[AOR = 6.93; 95％CI（1.56,30.71）]，临床经验（3-5年）[AOR = 0.168; 95％CI（0.060-0.469）]，插入部位（手臂）[AOR = 0.126； 95％CI（0.046-0.349）]，移除原因（移位和并发症）[AOR = 8.15；95％CI（2.49,26.63）[AOR = 10.48; 95％CI（3.08,35.65）]，药物治疗[AOR = 0.17; 95％CI（0.37,0.784）]，糖皮质激素[0.164; 95％CI（0.034,0.793）]和输血[AOR = 0.12; 95％CI（0.028-0。[509]]是与外周静脉插管的寿命相关的统计学上显着的变量。结论在婴儿和人群中，及时清除外周静脉插管的比例较高。插管和医疗保健因素对外周静脉插管的寿命有重大影响。
