Abstract: An antibacterial fluid may be applied to a tubular medical cannula for access to a patient. The fluid comprises a metabolizable antibacterial formulation having a viscosity of at least about 5,000 cp. The cannula may then be inserted into the patient with an increased lubricity for a reduction of pain, while at the same time, unlike silicones, currently preferred materials do not readily accumulate in the patient. The tubular medical cannula may be a rigid, hollow needle, sharp or blunt, a spike, or a flexible catheter. Also, the viscous antibacterial fluid may be used to lock a catheter or other cannula while implanted in the patient, for storage purposes.
