Two types of intravenous nitroglycerin (NTG) perfusion sets were studied using laboratory techniques. A known concentration of NTG was placed in each of these sets, and an evaluation was made as to the dose of NTG actually received by the patient after passage of the NTG solution through the sets. Set number one consisted of a glass container and polyvinyl chloride (PVC) tubing. After passage through this set, there was a rapid and significant decrease in the NTG concentration, i.e. the dose actually received by the patient is less than the dose theoretically administered. Set number two consisted of a polypropylene syringe and polyethylene tubing. After passage through this set, there was no significant change in the NTG concentration, i.e. the patient receives the full theoretical dose.
使用实验室技术研究了两种类型的静脉注射硝酸甘油（NTG）灌注装置。将已知浓度的NTG放入每组装置中，并评估NTG溶液通过装置后患者实际接受的NTG剂量。第一组装置由一个玻璃容器和聚氯乙烯（PVC）管组成。NTG溶液通过该组装置后，NTG浓度迅速且显著降低，即患者实际接受的剂量低于理论给药剂量。第二组装置由一个聚丙烯注射器和聚乙烯管组成。NTG溶液通过该组装置后，NTG浓度没有显著变化，即患者接受了全部理论剂量。
