Patients requiring frequent blood sampling and/or frequent intravenous fluid administration can be difficult to manage clinically once peripheral veins become exhausted. Not only can peripheral vascular access be difficult in these patients, but patients begin to dread the attempts at blood sampling and intravenous line placement more than the chemotherapy regimen.At Howard University Hospital, several different types of commercial vascular access devices have been employed that afford reliable and dependable use in cancer patients requiring chemotherapy and blood monitoring. With the increased use of these devices, one unpleasant aspect in the management of the cancer patient, that of repeated attempts at vascular access, can be eliminated.
一旦外周静脉无法再使用，临床上对需要频繁采血和/或频繁静脉输液的患者进行管理就会变得困难。这些患者不仅外周血管通路难以建立，而且比起化疗方案，他们开始更惧怕采血尝试和静脉置管。在霍华德大学医院，已经采用了几种不同类型的商用血管通路装置，这些装置在需要化疗和血液监测的癌症患者中使用可靠且稳定。随着这些装置使用的增加，癌症患者管理中一个令人不快的方面，即反复尝试建立血管通路的问题，可以得到消除。
