Risk of burn injuries caused by high illumination intensity

Page 20
General
The xenon illumination is a light source with high intensity. If used improperly,
excessive illumination intensities may lead to third-degree burns. Keep the
illuminated tissue moist and make sure it is sufficiently rinsed. Carefully
monitor the effect of the illumination on the tissue, particularly under the
following circumstances:
– During longer interventions on skin and tissue using objective lenses with
short focal depth (short working distance),
– During interventions on poorly perfused tissue,
– When the brightness control for the xenon lamp is set to a high
illumination intensity.
Please bear in mind that the values displayed for the light intensity may
not be used as a measuring function. They are intended only as an aid to
orientation.
• Only change the xenon lamp module after switching off the system.
The igniter generates a high voltage when the lamp is on.
• Any type of radiation has a damaging effect on biological tissue. This is
also true for the light illumination the surgical field. You should therefore
reduce brightness, the illuminated field size and the light exposure time to
the absolute minimum required.
If the brightness can no longer be reduced in the case of malfunctions, you
must take this into account in the light exposure time.
Various factors influence the risk of burn injuries:
System-related factors
– The wavelength range is limited by filters to the visible range between
400 nm and 700 nm in order to reduce the risk of burn injuries.
– The illumination intensity decreases with increasing number of operating
hours of the light source. In case of a lamp exchange, illumination
increases to the originally high value.
Surgery-related factors
– The selected intensity of the light source is a major factor for the risk of
injury. It should always be set to the minimum required for the surgical
procedure to be performed.
