190913 -    1.  I would not put a separate port in for this.  It's just a
190914 -        matter of placing a Huber needle which the chemo nurses, I
190915 -        believe, have done for other patients.  I'll check. ref DRT 1

190924 -            [On 080501 Brigid explained that CT test injections of
190925 -            contrast medium causes higher pressures on the port
190926 -            catheter, and so UCSF began installing only Power Ports
190927 -            designed for higher pressures, ref SDS 50 TQ6F; in some
190928 -            cases UCSF approves using port catheter for injecting CT
190929 -            test contrast medium, and in order to avoid injury, pain,
190930 -            and suffering. ref SDS 50 JJ9N

190937 -            avoid further injury, pain, and suffering, ref SDS 51 VG5J;
190938 -            there is also consideration of using the existing port
190939 -            catheter by slowing the rate of injecting contrast medium
190940 -            for CT tests (point 2), if that is possible, which reduces
190941 -            risk of damaging the port from high pressure that occurs

190963 -         ..
190964 -        OBJECTIVE. This study evaluates the feasibility, safety, and
190965 -        efficacy of power-injecting IV contrast media through central
190966 -        venous catheters for CT examinations.
190968 -         ..
190969 -        SUBJECTS AND METHODS. Two hundred ninety-five CT examinations
190970 -        were performed during an 18-month period in 225 patients with
190971 -        indwelling central venous catheters. Patients were randomized
190972 -        to power injection either through peripheral IV catheter or
190973 -        through central venous catheter. Feasibility was defined as
190974 -        the percentage of patients with contrast material injected
190975 -        successfully through the randomized access route. Safety was
190976 -        evaluated by comparing patients with complications. Efficacy
190977 -        was evaluated by comparing contrast enhancement of the
190978 -        thoracic aorta, pulmonary artery, abdominal aorta, and liver.
190980 -         ..
190981 -        RESULTS. Two hundred nine patients had randomization data
190982 -        recorded. One hundred three (94%) of 109 patients were
190983 -        successfully injected through their indwelling catheter
190984 -        compared with 42 (42%) of 100 through a peripherally placed IV
190985 -        catheter (p < 0.001). After reassignment for unsuccessful
190986 -        access, 174 patients underwent central venous catheter
190987 -        injection, and 51, peripheral IV catheter injection. No
190988 -        statistically significant difference was noted in the
190989 -        complications between the central venous catheter and
190990 -        peripheral IV catheter groups. Enhancement was greater in the
190991 -        thoracic aorta, pulmonary artery, and liver for the peripheral
190992 -        IV catheter group (p < 0.03).
190994 -         ..
190995 -        CONCLUSION. Power injection of contrast media through central
190996 -        venous catheters for CT examinations is feasible and safe when
190997 -        set hospital guidelines and injection protocols are followed.
190998 -        This technique provides an acceptable alternative in patients
190999 -        without adequate peripheral IV access when bolus contrast
191000 -        enhancement is desired.

191006 -        Port catheters can be accessed using 19-gauge hook-type needles
191007 -        (Huber needle; Baxter, Deerfield, IL), to inject contrast
191008 -        medium for CT tests.
191010 -  ..
191011 - This seems to suggest the Huber needle works with the existing port
191012 - catheter, as indicated by the doctor's letter today, per above.
