Diagnosis of the cause of malfunction of indwelling catheters for insulin injections by the use of digital fluoroscopy.
BACKGROUND
Subcutaneous indwelling catheters are used for reducing pain when injecting insulin and other drugs.


OBJECTIVE
To use digital fluoroscopy for the diagnosis of catheter malfunction.


METHODS
Seven children (aged 5-11 years) with diabetes mellitus were studied. They used indwelling catheters (Insuflon) for insulin injections. Contrast medium was injected into the problem catheter.


RESULTS
The subcutaneous position of the catheter was correct in all cases, but we found two cases of delayed absorption caused by lipohypertrophy and one case of leakage.


CONCLUSIONS
Digital fluoroscopy is a useful method for determining potential problems with indwelling catheters.
