Update: Pyxis/Anesthesia Workstations

February 14, 2020  //  FOUND IN: Updates & Resources

Please be advised that reports have declined that Pyxis and Anesthesia Workstations (AWS) are freezing. The Pyxis vendor tested a fix on multiple Pyxis machines Thursday evening, but needs more time to ensure the repair is effective.

For more than a week, Pyxis cabinets have been freezing in the middle of medication removal, requiring reboots across many units/areas. On Thursday, incidents escalated. Once a cabinet freezes it cannot be used until the system is rebooted.

The vendor will continue to monitor the problem and report regularly to Michigan Medicine leadership. Once a repair proves to be effective, it will be implemented on all machines. The vendor has not yet determined a root cause for the problems.

Please continue to report any instances of Pyxis freezes to Pyxis-Admin@med.umich.edu. If a Pyxis cabinet needs to be rebooted, please follow the instructions below:

  • To reboot the cabinet, press the button to the off position (located on the back of the cabinet). It may take 2-3 minutes for the screen to go blank, power the cabinet back on at that time. It may take 5-10 minutes for the cabinet to fully reboot. 
  • In the event of an emergency and a medication is needed before the cabinet comes back up, employees should remove the medication per the following:
    • Remove the medication from another Pyxis in your area
    • Remove lifesaving medications from the crash cart (controlled substances are not in the crash cart)
    • Call the pharmacy that services your area to get the medication
    • Go to another unit, request visitor access and remove the medication


The safety of employees and patients is the organization’s No. 1 priority. Your commitment to providing the best possible patient care during this incident is truly appreciated.
