杂谈

(1)安装前应先调试胰岛素泵,使基本程序设置无误。
(2)检查胰岛素是否失效,并提前将其放置在室温下,用胰岛素贮存器抽取所需胰岛素量后排尽注射器内空气。
(3)部位选择。常取下腹部为输注部位,避开沿着腰带周围和腰围处及距脐4~5cm区域内。新输注部位与上一次输注部位应相隔2~3cm以上。
(4)安装胰岛素泵。清洁安装者双手,避免触到贮存容器和输注装置的未端或胰岛素瓶的顶部。用75%乙醇在输注部位由内向外局部消毒,自然干燥,将针尖以助针器迅速插入,避免打弯影响输注液流人。垂直进针,轻轻转动拔除辅针,贴好胶布。
(5)设定基础量及餐前量:大多数胰岛素泵使用者在泵治疗开始时需要胰岛素总量比他们用泵前总量减少约25%,长期稳定后,减少15%~17%,故-计算最初用量时即应将用泵前总量减少25%。一般计算所得的总量50%定为基础量,50%为餐前大剂量分次输注,但临床应用时具体剂量分配需因人而异。如果因为有持续高血糖或低血糖而考虑病人用泵前每日总剂量有误差,起始基础量则应该按照当前体重来估计.适宜的每日起始总量可用每日每公斤体重0.5U。
(1) insulin pump installed before testing, so the basic procedures for setting correct.
(2) to check whether the failure of insulin, and place it ahead of time at room temperature with insulin reservoir to extract the required amount of insulin syringe back to make the air.
(3) site selection. Often remove parts of the abdomen for the infusion to avoid the belt down and around the waist and 4 ~ 5cm away from the umbilical region. Infusion site and on the new infusion site should be separated by a 2 ~ 3cm above.
(4) insulin pump installed. Installers hands clean and avoid touching the storage containers and infusion devices at the end or the top of the insulin bottle. With 75% ethanol infusion at the site from the inside out local disinfection, natural drying, the needle tip to facilitate rapid insertion devices, to avoid playing people turn affect infusion flow. Vertically into the needle, gently rotate Des needle extraction, good adhesive plaster paste.
(5) set the basic amount of volume and fasting: the majority of users of insulin pump therapy at the beginning of necessary pump total insulin pump than their pre-reduced by about 25% of the total, long-term stability, the reduction of 15% ~ 17%, it - the calculation of the initial dosage should be used when the pump before the total amount of 25% reduction. Generally calculated as 50% of the total amount of basic, 50% for fasting fractionated high-dose infusion, but the clinical application of the specific dose required varies from person to person distribution. Because if there is persistent high blood sugar or low blood sugar and the patients with pre-pump total daily dose of a margin of error, the initial basic amount should be estimated in accordance with the current weight. Appropriate initial total daily per kilogram of body weight per day available 0.5U .
