Port kateter yerleştirilmesi, onkoloji hastalarında uzun dönem tedavide kullanılan bir girişimdir. Ancak girişim sonrası birçok komplikasyon meydana gelebilmektedir. Hastanın şikayeti mevcut ise lokalizasyonu ve buna bağlı oluşabilecek komplikasyonlar belli aralıklarla kontrol edilmelidir. En nadir görülen komplikasyonlardan birisi de kateterin yer değiştirmesidir. Bizim olgumuzda, subklavian v...

Urban pollution caused by road particles is widely criticized. The complex and changeable internal flow field of the dust suction port has greatest influence operation effect. aim this paper to explore law various influencing factors on characteristics sweeper’s port, reveal its mechanism efficiency port. results study show that: increasing width outlet diameter will change characteristics, acc...

This paper reports on a dielectrically actuated and piezoresistively sensed 4.41 GHz silicon bar resonator with an electromechanical Q (Qem) of 8180. The 2-port piezoresistive transconductance measurement performed provides a promising alternative to capacitive measurement at high frequencies, where nominal and feed-through capacitance often dominates the output signal. The electromechanical f·...

background: long-term tunneled catheters are used for the hemodialysis or chemotherapy in many patients. proper placement of the catheter tip could reduce early and late catheter related complications. aim of the present study was to evaluate a new formula for proper placement of tunneled hemodialysis or infusion port device by using an external anatomic landmark. materials and methods: a total...
