Interference Between Surgical Magnetic Drapes and Pacemakers

Not Applicable
Completed
Conditions
Electromagnetic Interference
Registration Number
NCT02617355
Lead Sponsor
Maisonneuve-Rosemont Hospital
Brief Summary

This study is designed to compare a new prototype surgical magnetic drape made with bottom-isolated ferrite magnets to 4 commercially available surgical magnetic drapes.

Detailed Description

Magnetic fields may potentially interfere with the function of cardiovascular implantable electronic devices. Sterile magnetic drapes used to hold surgical instruments are often placed on the patient's thorax, and they are likely to interfere with the function of these devices.

This study compares the magnetic interference of a new prototype surgical magnetic drape made with bottom-isolated ferrite magnets to the Covidien magnetic drape and 3 other commercially available surgical magnetic drapes.

Primary Outcome Measures
NameTimeMethod
Percentage of magnetic interferenceWithin 2 minutes after placement of surgical magnetic drape to the patient's chest

Percentage of patients experiencing magnetic interference with the application of each surgical magnetic drape.
