This particular provide chain concern pertains to the dearth of provide of blue dye some producers use to color the particular low-friction plunger-style epidural syringe. This syringe is necessary as a result of anaesthetists use it to determine the epidural house within the affected person’s again.
The syringe is normally stuffed with saline and related to the hole epidural needle, which is then slowly superior into the again.
