改良药物配制法减少输液袋内气泡形成的效果研究

Research in effect of modified drug preparation method on reduction of air bubble formation in infusion bags

目的探讨药物配制时减少气泡形成的方法。方法将药房所发药物随机分为对照组和实验组各100份。实验组采用配药时输液袋平放于桌面，针头平行刺入袋内，并浸没于液体内。对照组采用配药时输液袋与桌面垂直，针头垂直刺入袋内，针头没有浸没于液体，与液体不接触。观察比较2组输液袋内气泡形成情况。结果实验组气泡形成情况明显少于对照组。结论改良的新方法配制药物时可减少气泡的形成。

Objective To investigate a new method to reduce air bubbles formation during drug preparation. Methods 200 portions of drugs from hospital pharmacy were randomly divided into the control group and the experimental group with 100 portions in each group. In the experimental group, the infusion bags were put flat on the desktop, the needles pierced into the bags parallel, and immersed in the liquid inside. In the control group, the infusion bags were put perpendicular to the desktop, the needle pierced into the bags vertically, the needles do not immersed in the liquid. Air bubble formation in the infusion bags was compared between the two groups. Results Air bubble formation in the experimental group was significantly less than that of the control group. Conclusions The modified new method for drug preparation can reduce the formation of air bubbles.
