Purpose
Little has studied the effect of the contrast injection by mechanical central catheters currently found most in vitro studies,
which have shown that speeds as high as 14ml/sec occurs no deterioration of the catheter.
Although in vivo studies have also been developed,
reaching speeds of only 2.5 ml / sec.
Most catheters are not manufacturers provide guidance on the use of power injectors in these catheters (1).
Currently the majority of existing studies in relation to the speed of injection,
are in vitro,
which show...
Methods and Materials
A study descriptive,
longitudinal and prospective patients hospitalized in the Hospital Universitario San Vicente Foundation of the city of Medellin,
Colombia from March 2010 until March 2012.
Inclusion criteria were: patients older than 18 years who had only venous access as a centerline and whose renal function was normal,
or creatinine clearance 30 to 60 ml / min,
depending upon local protocol nephroprotection,
patients with renal CKD who were on hemodialysis or peritoneal dialysis.
Exclusion criteria were: patients who had doubts about the integrity and...
Results
Hospitalized patients were included in the Hospital Universitario San Vicente Foundation,
the city of Medellin,
Colombia.
Of the 55 patients included in the study,
26 were women (47.3%) and 29 men (52.7%),
with a median age of 53 years (18-85 years) (Figure 1).
Personal history,
20 patients (36.4%) had hypertension,
11 patients (20%) were diabetic,
2 patients with coronary artery disease (3.6%),
2 with a history of arrhythmias (3.6%) and 2 with prior history of allergic reactions,
and penicillin one another to tramadol (3.6%).
There...
Conclusion
In conclusion we can say that using our results could improve the ability to access imaging studies in all patients without peripheral venous access and who have only a central venous access,
prescribed precautions being able to inject with speeds above 3 cm / sec.
