Heparina frente a cloruro sódico 0,9% para mantener permeables los catéteres venosos centrales. Una revisión sistemática

Poor evidence supports effectiveness of intermittent heparin flushing vs. NaCl 0.9% solution, although methodological limitations and small sample size make these findings very inconsistent. In infection prophylaxis, there is no data allowing us to conclude if heparin flushing is more effective than NaCl 0.9% solution. More randomized clinical trials are needed.
