Multi-Use Vial Spike Replacement

Yes, you can replace a spike on a multi-use vial with a new sterile spike, provided you maintain strict aseptic technique and the vial's sterility has not been compromised. 1

Key Requirements for Spike Replacement

When replacing a spike on a multi-use vial, you must adhere to the following infection control principles:

Sterile Technique Protocol

  • Always use a completely sterile device (including both the new spike and any associated syringe) to access the multi-dose vial 1
  • Cleanse the access diaphragm with 70% alcohol before inserting the new spike into the vial 1
  • Avoid touching the access diaphragm during the spike replacement process to prevent contamination 1

Timing Considerations

  • Replace the spike when 72 hours have elapsed since initial placement, as extrapolated from CDC administration set guidelines 2
  • Replace immediately if any visible contamination or breach in sterility occurs 2

Critical Safety Measures

  • Discard the entire multi-dose vial immediately if sterility is compromised at any point during spike replacement 1, 2
  • Keep multi-dose vials away from the immediate patient treatment area to prevent inadvertent contamination by spray or spatter 1, 2
  • Never reuse syringes even if the needle is changed when accessing multi-dose vials 1, 2

Common Pitfalls to Avoid

The most critical error is failing to maintain sterility during the spike replacement process. Any contact with non-sterile surfaces, failure to adequately cleanse the diaphragm, or touching the access point compromises the vial and necessitates its immediate disposal 1. Additionally, leaving a spike in place beyond 72 hours without replacement increases infection risk based on administration set guidelines 2.
