Implanted pumps (e.g., insulin, morphine, anticancer drugs) have depth limits.+

Here's why it's a good idea to find out manufacturers' recommendations.

Abstract

Study design: Case report. Objectives:To describe the case of a spinal cord injury patient that went scuba diving resulting in a mechanical deformation of his intrathecal baclofen pump.Setting:University Hospitals Leuven, Belgium. Methods: Case report. Results: Diving below 10 meters of depth can result in irreversible mechanical damage of the drug reservoir of an intrathecal baclofen pump.Conclusionatients with an intrathecal baclofen pump should be warned for the risks associated with scuba diving and should not dive more than 10 meters below sea level."

Can you access the full text? I wonder what the manufacturer guidelines say.

Morning DDM,

I couldn't get to it.

Sorry.

According to Medtronic, their SynchroMed device testing showed that pressures above 2 ATA showed decreased flow rate and pump damage is possible. Prior to hyperbaric treatment, the pump should be filled to capacity; no changes to infusion programming should be made. Conversely at high altitudes, the concern is for increased flow rates. Ref "System Components; Hyperbaric Conditions " pp 16-17, about 3/4's into this: http://professional.medtronic.com/w...uro/documents/documents/synchii-ref-guide.pdf . Note that these models use a pressurized gas envelope around the reservoir to ensure a constant drug supply entering the dispensing mechanism.

Thanks Doc, no worries, was just curious.
