This prospective observational study collected data from pediatric patients aged less than 18 years who required PIVC. The participants were categorized into five groups for subgroup analysis: newborn, infant, toddler, pre-school, and student (children and adolescent). Data on demography, biochemistry, and PIVC executors were examined to elucidate the most powerful factors affecting the success of PIVC.
A total of 935 peripheral venous cannulations conducted within 1 year were studied. Age-subgroup analysis showed the highest failure rate (FR) of PIVC in the infant group (18.4%). No significant difference in BMI standard deviation score was noted among the groups (p-value = 0.430). Compared with those for the success group, more attempts, longer completion time, and more medical staff were needed for the failure group (all p-values < 0.05). A high serum procalcitonin level was correlated with an increased FR (p-value = 0.016). In addition, the success rate was positively associated with the seniority of the operators, except for the 3-year experienced R3 group (93.5%) showing a higher success rate than the 4-year experienced CR group (84.2%).
Difficulty in setting up PIVC was the greatest in infants and even greater than that in newborns. Even though seniority was a cardinal factor in successful PIVC, a high FR was still noted despite the lack of continuous and steady practice.
方法:这项前瞻性观察性研究收集了18岁以下需要PIVC的儿科患者的数据。将参与者分为五组进行亚组分析:新生儿,婴儿,蹒跚学步的孩子,学前,和学生(儿童和青少年)。人口数据,生物化学,和PIVC执行者进行了检查,以阐明影响PIVC成功的最有力因素。
结果:研究了1年内进行的935例外周静脉插管。年龄亚组分析显示,婴儿组的PIVC失败率(FR)最高(18.4%)。各组间BMI标准差评分无显著差异(p值=0.430)。与成功组相比,更多尝试,完成时间更长,失败组需要更多的医务人员(所有p值<0.05)。高血清降钙素原水平与FR升高相关(p值=0.016)。此外,成功率与操作人员的资历呈正相关,除了3年有经验的R3组(93.5%)的成功率高于4年有经验的CR组(84.2%)。
结论:建立PIVC的难度在婴儿中最大,甚至大于新生儿。尽管资历是PIVC成功的主要因素,尽管缺乏持续和稳定的实践,但仍注意到高FR.
