Under either general or topical anesthesia, undiluted vitreous fluid (200 900 µl) was first collected by 3-port pars plana vitrectomy using a 20- or 23-gauge vitreous cutter with a 5 mL-syringe, followed by irrigation from infusion port.
A 30 cm extension line with infusion port was attached and the catheter was held in place with elastic tape.
To enable optimal distribution of the study drug, 0.9% sodium chloride solution, 500 ml was administered via the i.p. port before each infusion.
Catheter models differ in that some contain an additional volume infusion port, and some have the ability to measure right ventricular end-diastolic volume.
Operation fees for placement of a central venous access port for continuous infusion of 5-FU were high for oxaliplatin-based regimens, because most FOLFOX regimens were used before FOLFIRI in this study.
They found that the incidence of vitreous incarceration and fibrovascular proliferation was maximum at the infusion port site and cited inadequate vitreous clearance at that site as a cause for proliferation.
This fact and the application of a CV catheter system with PAS or vital port and portable infusion pump thus enable the patients to receive outpatient-basis treatment which is equivalent to the inpatient treatment in quality.
Two potential advantages attributed to its use are (1) taurolidine may prevent the formation of biofilm on the internal surface of the catheter and inside the subcutaneous reservoir of infusion ports [ 20, 21].
For longer runs, additional calibrant can be injected using a six-port valve and an infusion pump during the time when no compounds are eluted.
This device has ports for eight infusions, which run through separate channels within a 150 cm flexible plastic tube.
Notably, results from two patients with simultaneous glucose infusion via another port of the CVC were excluded in the analysis.
